bottomnavigationview with navigation Drawer - java

I want to implement a bottomnavigationview with a navigation drawer as an interior element
I managed to create a bottomnavigationview and a navigation drawer but I don't see how to put the navigation drawer in the bottomnavigationview
My MainActivity java:
public class MainActivity extends AppCompatActivity {
private static final String TAG = "debinf MainActivity";
//public static final String FRAGMENT_KEY = "fragment";
private BottomNavigationView bottomNavigationView;
private NavigationView navigationView;
private DrawerLayout drawerLayout;
private NavController navController;
private AppBarConfiguration appBarConfiguration;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Log.i(TAG, "onCreate: ");
bottomNavigationView = (BottomNavigationView) findViewById(R.id.main_bottom_nav);
navigationView = (NavigationView) findViewById(R.id.main_sidebar);
drawerLayout = (DrawerLayout) findViewById(R.id.main_drawer);
setupNavigation();
}
private void setupNavigation() {
Log.i(TAG, "setupNavigation: ");
navController = Navigation.findNavController(this, R.id.main_fragment);
appBarConfiguration =
new AppBarConfiguration.Builder(R.id.navigation_friends,R.id.navigation_order,R.id.navigation_home,R.id.navigation_groups,R.id.navigation_settings,R.id.navigation_profile,R.id.navigation_all_activity) //Pass the ids of fragments from nav_graph which you dont want to show back button in toolbar
.setDrawerLayout(drawerLayout)
.build();
NavigationUI.setupActionBarWithNavController(this, navController, appBarConfiguration); //Setup toolbar with back button and drawer icon according to appBarConfiguration
NavigationUI.setupWithNavController(navigationView, navController);
NavigationUI.setupWithNavController(bottomNavigationView, navController);
/*
** Listener for bottomNavigation must be called after been setupWithNavController
** This command will override NavigationUI.setupWithNavController(bottomNavigationView, navController)
** and the automatic transaction between fragments is lost
* */
//bottomNavigationView.setOnNavigationItemSelectedListener(this);
//navigationView.setNavigationItemSelectedListener(this);
}
#Override
public void onBackPressed() {
Log.i(TAG, "onBackPressed: ");
if (drawerLayout.isDrawerOpen(GravityCompat.START)) {
Log.i(TAG, "onBackPressed: DRAWER IS OPEN - CLOSING IT");
drawerLayout.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}
#Override
public boolean onSupportNavigateUp() {
Log.i(TAG, "onSupportNavigateUp: ");
// replace navigation up button with nav drawer button when on start destination
return NavigationUI.navigateUp(navController, appBarConfiguration) || super.onSupportNavigateUp();
}

How to apply drawerlayout on specific fragments?

I have the following problem:
I want to use navigation components and therefore I have only one activity (MainActivity) and several fragments.
I have two types of fragments: authenticating stuff and the actual app.
The actual app contains a drawer layout and the auth stuff should only be in contraint layouts.
But the problem is that the auth fragments also are showing the statusbar of the drawer layout.
I tried to hide the actionbar on these fragments calling ((AppCompatActivity)getActivity()).getSupportActionBar().hide();
But this did not work and I got a black space at the top of the screen.
Is there any way to apply the drawerlayout to specific fragments or a general better approach to get this behavior?
MainActivity.java
public class MainActivity extends AppCompatActivity
{
private NavController navController;
private DrawerLayout drawerLayout;
private AppBarConfiguration appBarConfiguration;
private NavController.OnDestinationChangedListener listener;
#Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
navController = Navigation.findNavController(this, R.id.fragment);
drawerLayout = findViewById(R.id.drawer_layout);
NavigationView navigationView = findViewById(R.id.navigationView);
NavigationUI.setupWithNavController(navigationView, navController);
appBarConfiguration = new AppBarConfiguration.Builder(R.id.firstFragment, R.id.secondFragment)
.setOpenableLayout(drawerLayout)
.build();
NavigationUI.setupActionBarWithNavController(this, navController, appBarConfiguration);
navController.addOnDestinationChangedListener((_c, destination, _b) ->
{
if (destination.getId() == R.id.mainFragment ||
destination.getId() == R.id.loginFragment ||
destination.getId() == R.id.registerUserFragment)
drawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_LOCKED_CLOSED);
else
drawerLayout.setDrawerLockMode(DrawerLayout.LOCK_MODE_UNLOCKED);
});
}

change burger icon side for nav drawer

I used a Android Studio Template for Side menu drawer.
Problem : I want the whole drawer to appear on right.
Progress : I can change the android:layout_gravity to "end" for drawer layout, but i cannot move the three-line-icon (also called shelf, burger or Navigation Drawer icon) in ActionBar to the right side.
Visual source to maybe provide better understanding of my problem:
Here comes the code :
Drawer activity (Lecture_graph.java) :
public class Lectures_graph extends AppCompatActivity implements course_list.OnFragmentInteractionListener, lectures_graph.OnFragmentInteractionListener{
private AppBarConfiguration mAppBarConfiguration;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_lectures_graph);
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
DrawerLayout drawer = findViewById(R.id.drawer_layout);
NavigationView navigationView = findViewById(R.id.nav_view);
// Passing each menu ID as a set of Ids because each
// menu should be considered as top level destinations.
mAppBarConfiguration = new AppBarConfiguration.Builder(
R.id.nav_course_list, R.id.nav_lectures_greph)
.setDrawerLayout(drawer)
.build();
NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment);
NavigationUI.setupActionBarWithNavController(this, navController, mAppBarConfiguration);
NavigationUI.setupWithNavController(navigationView, navController);
}
#Override
public boolean onSupportNavigateUp() {
NavController navController = Navigation.findNavController(this, R.id.nav_host_fragment);
return NavigationUI.navigateUp(navController, mAppBarConfiguration)
|| super.onSupportNavigateUp();
}
#Override
public void onFragmentInteraction(Uri uri) {
}
}

Will be thankful for any help.
you can use ActionBarDrawerToggle.
try this (kotlin) :
val toggle = ActionBarDrawerToggle(
this, drawer_layout, toolbar,
R.string.navigation_drawer_open,
R.string.navigation_drawer_close
)
toggle.isDrawerIndicatorEnabled = false
toggle.setHomeAsUpIndicator(R.drawable.ic_menu_black_24dp)
toggle.setToolbarNavigationClickListener {
if (drawer .isDrawerVisible(GravityCompat.START)) {
drawer .closeDrawer(GravityCompat.START)
} else {
drawer .openDrawer(GravityCompat.START)
}
}
drawer .addDrawerListener(toggle)
toggle.syncState()
for (Java)
Toolbar toolbar = findViewById(R.id.toolbar);
DrawerLayout drawer = findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar,
R.string.navigation_drawer_open,
R.string.navigation_drawer_close
);
toggle.setDrawerIndicatorEnabled(false);
toggle.setHomeAsUpIndicator(R.drawable.ic_menu_black_24dp);
toggle.setToolbarNavigationClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (drawer .isDrawerVisible(GravityCompat.START)) {
drawer .closeDrawer(GravityCompat.START);
} else {
drawer .openDrawer(GravityCompat.START);
}
}
});
drawer .addDrawerListener(toggle);
toggle.syncState();

Open navigation drawer menu in another activity

I have created the navigation drawer menu and now i want it to appear in my main activity.
I have the following code in my main activity:
public class MainActivity extends sideMenu {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
FrameLayout contentFrameLayout = (FrameLayout) findViewById(R.id.content_frame);
getLayoutInflater().inflate(R.layout.activity_main, contentFrameLayout);
}}
When i run the app it crashes when entering main activity and it tells this:
**Caused by: java.lang.IllegalStateException: This Activity already has an action bar supplied by the window decor. Do not request Window.FEATURE_SUPPORT_ACTION_BAR and set windowActionBar to false in your theme to use a Toolbar instead.**
It specifies the error is in two places:
Menu activity -
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
Main activity -
super.onCreate(savedInstanceState);
If someone can shed some light here i'd be grateful!

Your theme already has an ActionBar so you will have to convert it to NoActionBar.
For Whole App:
Open the styles.xml and make sure the last line of the parent has a word NoActionBar for example :
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar"> <!-- changed .DarkActionBar to .NoActionBar -->
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>
<item name="colorAccent">#color/colorAccent</item>
For An Activity:
Or you can just change it for one particular activity in the Manifest like by adding this atrribute in the Manifest :
android:theme="#style/Theme.AppCompat.Light.NoActionBar"
use this theme.
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>

Android Object coming back null after onCreate

Android newbie here.
I'm trying to set an onClick event on a LinearLayout. But I keep getting the error
Attempt to invoke virtual method 'void android.widget.LinearLayout.setOnClickListener(android.view.View$OnClickListener)' on a null object reference
Which, if I understand correctly means that the reference is null. Which doesn't make sense to me since I'm calling it after onCreate
Here's my code, anybody have any clues what I'm doing wrong?
MainActivity - The place with HERE! is where the crash is occuring
package ...
import ...
public class MainActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();
final NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
setNavHeaderOnClickAction();
}
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// ...
}
public void setNavHeaderOnClickAction(){
// HERE! Here's the problemsome area
LinearLayout navHeaderUser = (LinearLayout) findViewById(R.id.nav_header_user);
navHeaderUser.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Intent myIntent = new Intent(MainActivity.this, UserProfile.class);
// MainActivity.this.startActivity(myIntent);
// DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
// drawer.closeDrawer(GravityCompat.START);
}
});
}

NavigationView header is usually included this way:
<android.support.design.widget.NavigationView
android:id="#+id/nvView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="#android:color/white"
app:headerLayout="#layout/main_drawer_header"
app:itemTextColor="#color/black"
app:menu="#menu/menu_main_drawer"
app:itemIconTint="#null"/>
Since support libraries version 23.1.0 NavigationView is using a RecyclerView and the header is added as one of RecyclerView's items.
Activity's findViewById won't find the header and its internals.
To get access to it you need to get the header from NavigationView and call findViewById relative to header view:
NavigationView navigationView = (NavigationView) findViewById(R.id.nvView);
View navHeaderview = navigationView.getHeaderView(0);
LinearLayout navHeaderUser = (LinearLayout) navHeaderview.findViewById(R.id.nav_header_user);
navHeaderUser.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Intent myIntent = new Intent(MainActivity.this, UserProfile.class);
// MainActivity.this.startActivity(myIntent);
// DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
// drawer.closeDrawer(GravityCompat.START);
}
});
Hope I got it right and it'll work for you!

extending NavigationDrawer Activity

I created NavigationDrawer class and now I`m creating new Activities which extends Navigation Drawer class. Unfortunately I am constantly getting such errors:
java.lang.IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.
java.lang.IllegalStateException: This Activity already has an action bar supplied by the window decor. Do not request Window.FEATURE_SUPPORT_ACTION_BAR and set windowActionBar to false in your theme to use a Toolbar instead.
here is the code for the NavigationDrawer Class:
public class Requests extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
public DrawerLayout drawer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.requests);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.setDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
#Override
public void onBackPressed() {
DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}
#SuppressWarnings("StatementWithEmptyBody")
#Override
public boolean onNavigationItemSelected(MenuItem item) {
int id = item.getItemId();
Intent in = getIntent();
if (in.hasExtra("warehouse"))
{
id = R.id.nav_warehouse;
}
else if (in.hasExtra("cash"))
{
id = R.id.nav_cash;
}
if (id == R.id.nav_warehouse) {
Intent i = new Intent(getApplicationContext(), WarehouseRequests.class);
startActivity(i);
} else if (id == R.id.nav_cash) {
Intent i = new Intent(getApplicationContext(), CashRequests.class);
startActivity(i);
} else if (id == R.id.nav_log_out) {
Intent i = new Intent(getApplicationContext(), LoginActivity.class);
i.putExtra("logout", 1);
startActivity(i);
}
return true;
}
}

View contentView = inflater.inflate(R.layout.warehouse, null, false);
drawer.addView(contentView, 0);
}
}
and here is what I have in styles:
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">#color/colorPrimary</item>
<item name="colorPrimaryDark">#color/colorPrimaryDark</item>

<style name="AppTheme.PopupOverlay" parent="Theme.AppCompat.Light.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
</resources>
add this to your styles.xml file
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
and apply this style to your Activity in the manifest.xml file.
android:theme="#style/AppTheme.NoActionBar"
android:theme="#style/AppTheme.NoActionBar"
add this to your warehouserequests activity in manifest file
