How can I nest fragments with a navigation drawer? - java

I've been trying for the last few hours to search around SO, but I couldn't find a solution outside of trying to create a workaround. I'm trying to create a navigation drawer for my app, but to do so I had to end up trying to change my base activity into a fragment. This is the result:
public class ToolReaderActivity extends Fragment implements ToolListFragment.OnToolSelectedListener, CompatActionBarNavListener, OnClickListener {
boolean mIsDualPane = false;
Context c;
ToolListFragment mToolListFragment;
InfoFragment mInfoFragment;
Fragment mContent;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
c = getActivity();
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.onepane_with_bar, container, false);
// find our fragments
mToolListFragment = (ToolListFragment) getActivity().getSupportFragmentManager().findFragmentById(R.id.toolList);
mInfoFragment = (InfoFragment) getActivity().getSupportFragmentManager().findFragmentById(R.id.toolInfo);
FragmentTransaction transaction = getActivity().getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.toolList, mToolListFragment).commit();
FragmentTransaction transaction2 = getActivity().getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.toolInfo, mInfoFragment).commit();
mToolListFragment.setContext(c);
mToolListFragment.setOnToolSelectedListener(this);
View infoView = getView().findViewById(R.id.toolInfo);
mIsDualPane = infoView != null && infoView.getVisibility() == View.VISIBLE;
int catIndex = savedInstanceState == null ? 0 : savedInstanceState.getInt("catIndex", 0);
setUpActionBar(mIsDualPane, catIndex);
mToolListFragment.setSelectable(mIsDualPane);
restoreSelection(savedInstanceState);
if (savedInstanceState != null) {
//Restore the fragment's instance
mContent = getActivity().getSupportFragmentManager().getFragment(savedInstanceState, "mContent");
}
return rootView;
}
...
...
...
}
The intended output is a activity with a navigation drawer and thus a fragment. The fragment contains this main activity ToolReaderActivity (named so because it was formerly an activity) which has 1-2 fragments inside of it. It's a ListFragment with a fragment showing the selected items information (as either another fragment if mDualPane is true or launched as a seperate activity otherwise).
I can't figure out a way to get this to work, I've tired changing the order that things are done using onCreate, onCreateView, onActivityCreated, but the error I keep getting is that mToolsListFragment is null at mToolsListFragment.setContext(c);

You can simply create NavigationDrawer with the code below.
public class MainActivity extends AppCompatActivity
{
private NavigationView mNavigationView;
private DrawerLayout mDrawerLayout;
private Toolbar toolbar;
private ActionBarDrawerToggle mDrawerToggle;
private FragmentActivity fragment;
private FragmentManager fragmentManager;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initDrawerNavigation();
fragmentManager = getFragmentManager();
}
public void initDrawerNavigation()
{
toolbar = (Toolbar) findViewById(R.id.toolbar);
toolbar.setTitle(R.string.app_name);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayShowHomeEnabled(true);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
mNavigationView = (NavigationView) findViewById(R.id.navigation_view);
mNavigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener()
{
#Override
public boolean onNavigationItemSelected(MenuItem item)
{
item.setChecked(true);
switch (item.getItemId())
{
case R.id.st_menu:
fragment = new FirstFragment();
break;
case R.id.nd_menu:
fragment = new Second Fragment();
break;
}
fragmentManager.beginTransaction().replace(R.id.container, fragment).commit();
mDrawerLayout.closeDrawers();
return true;
}
});
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, toolbar, R.string.drawer_open,
R.string.drawer_close)
{
// Called when a drawer has settled in a completely closed state.
public void onDrawerClosed(View view)
{
super.onDrawerClosed(view);
}
// Called when a drawer has settled in a completely open state.
public void onDrawerOpened(View drawerView)
{
super.onDrawerOpened(drawerView);
}
};
mDrawerLayout.addDrawerListener(mDrawerToggle);
}
#Override
protected void onPostCreate(Bundle savedInstanceState)
{
super.onPostCreate(savedInstanceState);
mDrawerToggle.syncState();
}
#Override
public boolean onCreateOptionsMenu(Menu menu){
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item){
switch(item.getItemId())
{
case android.R.id.home:
mDrawerLayout.openDrawer(GravityCompat.START); // OPEN DRAWER
return true;
}
return super.onOptionsItemSelected(item);
}
}
Here you have activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="?attr/colorPrimary"
android:minHeight="?attr/actionBarSize"
app:theme="#style/ThemeOverlay.AppCompat.ActionBar" />
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="#dimen/activity_vertical_margin"
tools:context=".MainActivity">
<include
layout="#layout/your_layout" />
<android.support.design.widget.NavigationView
android:id="#+id/navigation_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:choiceMode="singleChoice"
app:menu="#menu/navigation_items" />
</android.support.v4.widget.DrawerLayout>
</LinearLayout>
your_layout can be anything you want. Now you define your FirstFragment class like here:
public class FirstFragment extends Fragment
{
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
ViewGroup view = (ViewGroup) inflater.inflate(R.layout.target_layout, container, false);
return view;
}
}
You can also refer to this question Navigation Drawer to switch between activities if you want to switch between activities and not fragments. Hope this helps.

No view found for ID

I'm trying to achieve Fragment to Fragment transaction with onOptionsItemSelected but I keep getting
java.lang.IllegalArgumentException: No view found for id
I also read this thread:
Android Fragment no view found for ID? and applied some answer to my code but it is not solve my problem
Here is my HomeFragment.java
private Toolbar toolbar;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
//Set Toolbar for Fragment
View v = inflater.inflate(R.layout.fragment_home, container, false);

((AppCompatActivity) getActivity()).setSupportActionBar(toolbar);
setHasOptionsMenu(true);
return v;
}
#Override

inflater.inflate(R.menu.toolbar_menu,menu);
super.onCreateOptionsMenu(menu, inflater);
}
#Override
public boolean onOptionsItemSelected(#NonNull MenuItem item) {
FragmentManager fm = getActivity().getSupportFragmentManager();
fm.beginTransaction().replace(R.id.cart_fragment_layout,new CartFragment())
.commitNow();
return super.onOptionsItemSelected(item);
}
}

and my CartFragment.java
public class CartFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View v = inflater.inflate(R.layout.fragment_cart, container, false);
return v;
}
}
My MainActivity.java just in case, I set HomeFragment as default:
public class MainActivity extends AppCompatActivity {
Toolbar toolbar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
toolbar = findViewById(R.id.main_toolbar);
setSupportActionBar(toolbar);
setContentView(R.layout.activity_main);
BottomNavigationView bottomNav = findViewById(R.id.bottom_navigation);
bottomNav.setOnNavigationItemSelectedListener(navListener);
getSupportFragmentManager().beginTransaction().replace(R.id.frament_container,
new HomeFragment()).commit();
}
private BottomNavigationView.OnNavigationItemSelectedListener navListener =
new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
Fragment selectedFragment = null;
switch (item.getItemId()){
case R.id.nav_home:
selectedFragment = new HomeFragment();
break;
case R.id.nav_menu:
selectedFragment = new MenuFragment();
break;
case R.id.nav_user:
selectedFragment = new UserFragment();
break;
case R.id.nav_more:
selectedFragment = new MoreFragment();
break;
}
getSupportFragmentManager().beginTransaction().replace(R.id.frament_container,
selectedFragment).commit();
return true;
}
};
}
The id you use in a fragment transaction is NOT the view id of a view in the fragment. Its the id of the fragment stub view in the layout you're popping the fragment into. So you're passing in the wrong id. I can't tell you what the right one is, as you don't give us the xml of your main layout.
Basically the fragment transaction looks for the id you pass out in the context root layout, then pops out what's already there and replaces it with your fragment.

navigation drawer not showing properly

Bottom nav view fragment NullPointerException

In my one of my fragments I have a toggle button in the xml:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"

<!-- TODO: Update blank fragment layout -->
<ToggleButton
android:id="#+id/metronome"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="ToggleButton" />
</FrameLayout>
And
toggleButton = (ToggleButton) getView().findViewById(R.id.metronome);
But when trying to open the fragment it crashes and the logcat shows that it was a
java.lang.NullPointerException:Attempt to invoke virtual method 'android.view.View android.view.View.findViewById(int)' on a null object reference
Here's the Main Activity:
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
BottomNavigationView bottomNavigationView = (BottomNavigationView)findViewById(R.id.bottomView);
bottomNavigationView.setOnNavigationItemSelectedListener(new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
switch (item.getItemId())
{
case R.id.moosic:
rhythm fragmentone = new rhythm();
android.support.v4.app.FragmentTransaction fragmentTransaction3 = getSupportFragmentManager().beginTransaction();
fragmentTransaction3.replace(R.id.frame, fragmentone, "rhythm");
fragmentTransaction3.commit();
return true;
case R.id.call:
intervals fragmenttwo = new intervals();
android.support.v4.app.FragmentTransaction fragmentTransaction2 = getSupportFragmentManager().beginTransaction();
fragmentTransaction2.replace(R.id.frame, fragmenttwo, "intervals");
fragmentTransaction2.commit();
return true;
case R.id.thinga:
piano fragmentthree = new piano();
android.support.v4.app.FragmentTransaction fragmentTransaction1 = getSupportFragmentManager().beginTransaction();
fragmentTransaction1.replace(R.id.frame, fragmentthree, "piano");
fragmentTransaction1.commit();
return true;
}
return false;
}
});
}
}
getView() might be returning null. Use the below code to reference the toggle button
View view = inflater.inflate(R.layout.fragmentlayout, container, false);
toggleButton = (ToggleButton) view.findViewById(R.id.metronome);

PreferenceFragmentCompat doesn't show

I need help to fix a problem with PreferenceFragmentCompat, which simply doesn't shows, no error in console, no message, nothing, just a blank page.
The fragment is shown as a result of the selection of an element in a navigation drawer. Here's the Activity XML:

Here's the Fragment's Java:
public class SettingsFragment extends PreferenceFragmentCompat {
View rootView;
#Override
public void onCreatePreferences(Bundle savedInstanceState, String rootKey) {
addPreferencesFromResource(R.xml.fragment_settings);
}
#Nullable
#Override
public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, Bundle savedInstanceState) {

public PreferenceFragmentCompat getCallbackFragment() {
return this;
}
public static SettingsFragment newInstance() {
Bundle args = new Bundle();
SettingsFragment fragment = new SettingsFragment();
fragment.setArguments(args);
return fragment;
}
}
I've removed all of the code which was useless for this purpose. Sorry for the huge amount of code.
I've figured it out by myself:
when you are using preferencefragment you cannot override the onCreateView method, or you'll get a blank screen.

How to Display Navigation Drawer in all activities?

I have a Navigation Drawer which should appear in all my activities.
I saw many questions similar to this & found a solution like Extending the MainActivity with the Other Activities .
So i extended My Main Activity to my Second Activity.But the Drawer is not being showed in the Second Activity
MainActivity
public class MainActivity extends ActionBarActivity
{
private ListView mDrawerList;
private DrawerLayout mDrawer;
private CustomActionBarDrawerToggle mDrawerToggle;
private String[] menuItems;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
supportRequestWindowFeature(WindowCompat.FEATURE_ACTION_BAR);
// getSupportActionBar().hide();
setContentView(R.layout.activity_main_drawer);
// enable ActionBar app icon to behave as action to toggle nav drawer
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setHomeButtonEnabled(true);
mDrawer = (DrawerLayout) findViewById(R.id.drawer_layout);
// set a custom shadow that overlays the main content when the drawer
// opens
mDrawer.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START);
_initMenu();
mDrawerToggle = new CustomActionBarDrawerToggle(this, mDrawer);
mDrawer.setDrawerListener(mDrawerToggle);
}
private void _initMenu()
{
NsMenuAdapter mAdapter = new NsMenuAdapter(this);
// Add Header
mAdapter.addHeader(R.string.ns_menu_main_header);
// Add first block
menuItems = getResources().getStringArray(R.array.ns_menu_items);
String[] menuItemsIcon = getResources().getStringArray(R.array.ns_menu_items_icon);
int res = 0;
for (String item : menuItems)
{
int id_title = getResources().getIdentifier(item, "string", this.getPackageName());
int id_icon = getResources().getIdentifier(menuItemsIcon[res], "drawable", this.getPackageName());

mDrawerList.setAdapter(mAdapter);
mDrawerList.setOnItemClickListener(new DrawerItemClickListener());
}

super.onPostCreate(savedInstanceState);
// Sync the toggle state after onRestoreInstanceState has occurred.

Here is my implementation.. hope it help
FIRST, this POST is concept.
SECOND, this is also the KEY one.
FINALLY, Here is combination of all answer in one place
BASE ACTIVITY
This is a base activity for all other activity
You can extends Activity or FragmentActivity or etc. base on your requirement.
Navigation Drawer setup here for one time.
public class BaseActivity extends FragmentActivity {
protected DrawerLayout mDrawer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.base_layout);
mDrawer = (DrawerLayout) findViewById(R.id.drawer_layout);
//This is about creating custom listview for navigate drawer
//Implementation for NavigateDrawer HERE !
ArrayList<DrawerListItem> drawerListItems = new ArrayList<DrawerListItem>();
drawerListItems.add(new DrawerListItem(0,"AIRĀ° DEVICES"));
drawerListItems.add(new DrawerListItem(1,"A/C Device [1]"));
drawerListItems.add(new DrawerListItem(1,"A/C Device [2]"));
drawerListItems.add(new DrawerListItem(1,"A/C Device [3]"));
drawerListItems.add(new DrawerListItem(0,"AIRĀ° FEATURES"));
drawerListItems.add(new DrawerListItem(2,"SLEEP MODE"));
drawerListItems.add(new DrawerListItem(2,"TRACKING MODE"));
drawerListItems.add(new DrawerListItem(2,"SETTINGS"));
DrawerAdapter mDrawerAdapter = new DrawerAdapter(this, R.layout.drawer_list_header, drawerListItems);
ListView mDrawerList = (ListView) findViewById(R.id.left_drawer);
mDrawerList.setAdapter(mDrawerAdapter);
}
}
BASE ACTIVITY XML
This xml layout is for Navigation Drawer
<?xml version="1.0" encoding="utf-8"?>
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<FrameLayout
android:id="#+id/content_frame"
android:layout_width="match_parent"
android:layout_height="match_parent">
</FrameLayout>
<!-- The navigation drawer -->
<ListView
android:id="#+id/left_drawer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_gravity="left"
android:scrollingCache="false"
android:background="#drawable/drawer_bg"
android:divider="#null"
android:choiceMode="singleChoice"/>
</android.support.v4.widget.DrawerLayout>
ALL OTHERS ACTIVITY
Other Activity just extends BaseActivity and define code as below.
The Navigation Drawer will appear for particular activity.
mDrawer is form BaseActivity. it's a protected variable.
public class Screen1 extends BaseActivity
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
//inflate your activity layout here!
View contentView = inflater.inflate(R.layout.screen1, null, false);
mDrawer.addView(contentView, 0);
//Do the rest as you want for each activity
}
SCREEN 1 XML SAMPLE
Design as you wish it each activity. no more Navigation Drawer Layout !
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
</LinearLayout>
NOTE
In this implementation, The Navigation Drawer doesn't bind with Action Bar. If you wish to do that do it in BaseActivity.Also, This guide is not cover all requirement. It's just a sample.
in onCreate of TutorialActivity don't call setContentView instead do this:
#Override
protected void onCreate(Bundle savedInstanceState)
{
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
LayoutInflater inflater = (LayoutInflater) this
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View contentView = inflater.inflate(R.layout.help, null, false);
mDrawer.addView(contentView, 0);
}
make mDrawer in MainActivity protected. and in R.layout.activity_main_drawer just keep drawer tag and the element with gravity left(or right).
I made a BaseActivity activity which extends SherlockActivity (or ActionBarActivity if is your case)
public class BaseActivity extends SherlockActivity
Then, make all your activities extends BaseActivity, like:
public class GlossaryActivity extends BaseActivity
Later, you must replace the activity layout with the one that correspond to your activity, I made a method in BaseActivity like that:
protected void replaceContentLayout(int sourceId, int destinationId) {
View contentLayout = findViewById(destinationId);
ViewGroup parent = (ViewGroup) contentLayout.getParent();
int index = parent.indexOfChild(contentLayout);
parent.removeView(contentLayout);
contentLayout = getLayoutInflater().inflate(sourceId, parent, false);
parent.addView(contentLayout, index);
}
I called this method on the onCreate method in each activity:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
super.replaceContentLayout(R.layout.activity_glossary, super.CONTENT_LAYOUT_ID);
}
super.CONTENT_LAYOUT_ID is the FrameLayout of the BaseActivity, and other param is the layout you want replace with
You omitted the #Override from your derived class onCreate.
UPDATE: I'm not sure what the effects are of calling setContentView twice but that could be the problem. Separate out the code that sets up the drawer, and call that from both of the onCreate methods.
I had this problem too. This is my implementation:
activity_main.xml - the child at index 1 in the CoordinatorLayout is the content_main.xml, this I can change in code.
<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">
<android.support.design.widget.CoordinatorLayout
android:id="#+id/coordinator"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
**<include layout="#layout/content_main" />**
<android.support.design.widget.FloatingActionButton
android:id="#+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="#dimen/fab_margin"
android:src="#android:drawable/ic_dialog_email" />
</android.support.design.widget.CoordinatorLayout>
<android.support.design.widget.NavigationView
android:id="#+id/nav_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:fitsSystemWindows="true"
app:headerLayout="#layout/nav_header_main"
app:menu="#menu/activity_main_drawer" />
</android.support.v4.widget.DrawerLayout>
I've created a class that uses inflates the others activities UI:
public class MyLayoutInflater {
public void inflate(Activity activity, int LayoutResource, android.app.ActionBar getSupportActionBar, Intent getIntent){
CoordinatorLayout coordinatorLayout = (CoordinatorLayout) activity.findViewById(R.id.coordinator);
android.view.LayoutInflater inflater = (android.view.LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View contentView = inflater.inflate(LayoutResource, null, false);
//change i so that it suits the child number in you coordinator layout
int i = 1;
coordinatorLayout.removeViewAt(i);
coordinatorLayout.addView(contentView, i);
getSupportActionBar.setTitle(actionBarTitle);
}
public void inflate(Activity activity, int LayoutResource, android.support.v7.app.ActionBar getActionBar, String actionBarTitle){
CoordinatorLayout coordinatorLayout = (CoordinatorLayout) activity.findViewById(R.id.coordinator);
android.view.LayoutInflater inflater = (android.view.LayoutInflater) activity
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View contentView = inflater.inflate(LayoutResource, null, false);
//change i so that it suits the child number in you coordinator layout
int i = 1;
coordinatorLayout.removeViewAt(i);
coordinatorLayout.addView(contentView, i);
getActionBar.setTitle(actionBarTitle);
}
}
Now on the other activities all you have to do is extend the MainActivity and call this method and give it the necessary parameters:
public class AnotherActivity extends MainActivity {
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
new MyLayoutInflater().inflate(this,R.layout.content_activity_another, getSupportActionBar(), getIntent());
}
}
Ok here is hacky way to do this, I use it only for special kind of debug build to set properties of views in realtime (design tool).
It has advantage that you can use your child activities as usual without, special behavior that is required in different answers.
so in BaseActvity you can add:
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
// WARNING: Hacky, use carefully!!!
ViewGroup androidBaseView = (ViewGroup) findViewById(android.R.id.content);
//this one in what child activity has just set in setContentView()
ViewGroup childContent = (ViewGroup) androidBaseView.getChildAt(0);
View drawerView = LayoutInflater.from(this)
.inflate(R.layout.base_activity_drawer, androidBaseView, false);
FrameLayout frameLayout = (FrameLayout) drawerView.findViewById(R.id.content);
androidBaseView.removeView(childContent);
frameLayout.addView(childContent);
androidBaseView.addView(drawerView);
}
and xml for drawer is just:
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/nav_drawer"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true">
<FrameLayout
android:id="#+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
<LinearLayout
android:id="#+id/drawer_for_components"
android:layout_width="240dp"
android:layout_height="match_parent"
android:layout_gravity="end"
android:orientation="vertical"
android:fitsSystemWindows="true"
/>
</android.support.v4.widget.DrawerLayout>
Here is a simple and fast way to do it in android studio:
Create a new activity (Navigation drawer activity) from the gallery, and name it whatever you want, android studio will create everything for you (the class and the xml files that you can customize it later)
In other activities you should extend your Navigation drawer activity, and make sure these other activities has "no action bar" in the manifests file (android:theme="#style/AppTheme.NoActionBar")
You should modify your other activities as follows:
public class Mainactivity extends NavActivity
{
super.onCreate(savedInstanceState);
LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
//inflate your activity layout here!
View contentView = inflater.inflate(R.layout.activity_main, null, false);
drawer.addView(contentView, 0);
}
Note: the mainactivity will extend the action bar of the NavActivity, the NavActivity has a full functional action bar that will call the navigation drawer
I hope it will work with you
Nowadays you should use Single-Activity App Architecture (source).
Then simple add Navigation Drawer to Main Activity
you can simply use <include/>
By creating a nav drawer
<?xml version="1.0" encoding="utf-8"?>
<androidx.drawerlayout.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:openDrawer="start">
and then include the layout in it
<include
layout="#layout/activity_accounts"
android:layout_width="match_parent"
android:layout_height="match_parent" />
in your main activity make setContentView(R.layout.your_drawer_activity)
take note that if you use this method you have to create a nav drawer layout for every activity you have, unless you found a way to do includes programmatically.
