I built a Navigation Drawer with fragments and an Activity. All the fragments have the icon and drawer access is smooth as butter, but there is nothing in the Activity. The Activity is the default "Home Page", so access to the Navigation Drawer is critical. Typically not calling toggle.syncState(); is the solution, but it fails in this case.
MainActivity:
public class MainActivity extends AppCompatActivity
implements NavigationView.OnNavigationItemSelectedListener {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(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);
drawer.addDrawerListener(toggle);
toggle.setDrawerIndicatorEnabled(true);
toggle.syncState();
NavigationView navigationView = findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
//Sets default fragment
Intent i = new Intent(MainActivity.this,GarageActivity.class);
startActivity(i);
navigationView.setCheckedItem(R.id.nav_garage);
}
//Name in Action bar
public void setActionBarTitle(String title) {
getSupportActionBar().setTitle(title);
}
#Override
public void onBackPressed() {
DrawerLayout drawer = findViewById(R.id.drawer_layout);
if (drawer.isDrawerOpen(GravityCompat.START)) {
drawer.closeDrawer(GravityCompat.START);
} else {
super.onBackPressed();
}
}
Activity in question:
public class GarageActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_garage);
getSupportActionBar().setTitle("My Garage");
}
}

First you need to enable actionbar's Home button. Then Assign Hamburger icon to Home button and write code to open the drawer in his listener. following are the steps:
Get hamburger/menu icon:
In the Project window, right-click the res folder and select New > Vector Asset.
Select Material icon as the asset type and then click the Icon button to open the Select Icon window.
Search for "menu" and select the menu icon (the icon is 3 horizontal lines).
Click OK, and then rename the file to "ic_menu" and click Next to import it.
Enable "Home" button in actionbar:
add this code in your onCreate method:-
ActionBar actionbar = getSupportActionBar();
actionbar.setDisplayHomeAsUpEnabled(true);
actionbar.setHomeAsUpIndicator(R.drawable.ic_menu);
Add code in onOptionsItemSelected method:
first create global variable of DrawerLayout so you can access it in other methods. add reference to that variable in onCreate and use it in onOptionsItemSelected to open the drawer. following is the code:
public class MainActivity extends AppCompatActivity {
private DrawerLayout mDrawerLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mDrawerLayout = findViewById(R.id.drawer_layout);
...
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
mDrawerLayout.openDrawer(GravityCompat.START);
return true;
}
return super.onOptionsItemSelected(item);
}
}

Main Activity ScreenI have made a custom calendar with textview, So I want the calendar to show current date and month when I open the calendar...
`My calendar should open directly in the current month and show the current date, just like google calendar.
<TextView

Hello, I do know that this is a duplicate question, but i was not able to find the solution from the other threads.
Here is my problem,
I have an app with bottom navigation bar with five fragment. I want to open the those fragment via the app shortcut.
Here what i have created,
shortcut.xml
<shortcuts xmlns:tools="http://schemas.android.com/tools"
xmlns:android="http://schemas.android.com/apk/res/android">
<shortcut
android:shortcutId="first"
android:enabled="true"
android:icon="#drawable/shortcut_1"
android:shortcutShortLabel="#string/shortcut_short_label_one"
android:shortcutLongLabel="#string/shortcut_long_label_one"
tools:targetApi="n_mr1">
<intent
android:action="com.xxxxxxx.xxxx.FIRST"
android:targetPackage="com.xxxxxxx.xxxx.test"
android:targetClass="com.xxxxxxx.xxxx.test.MainActivity" />
</shortcut>
<!-- Specify more shortcuts here. -->
<shortcut
android:shortcutId="second"
android:enabled="true"
android:icon="#drawable/shortcut_2"
android:shortcutShortLabel="#string/shortcut_short_label_two"
android:shortcutLongLabel="#string/shortcut_long_label_two"
tools:targetApi="n_mr1">
<intent
android:action="com.xxxxxxx.SECOND"
android:targetPackage="com.xxxxxxx.xxxx.test"
android:targetClass="com.xxxxxxx.xxxx.test.SecondFragment" />
</shortcut>
</shortcut>
Here is the onCreate() from the MainActivity
private static final String Second = "com.xxxxxxx.xxxx.SECOND";
//code vomited
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (Second.equals(getIntent().getAction())){
SecondFragment secondFragment = new SecondFragment();
android.support.v4.app.FragmentTransaction fragmentTransactionTwo = getSupportFragmentManager().beginTransaction();
fragmentTransactionTwo.replace(R.id.content_main, secondFragment, "Fragment two");
fragmentTransactionTwo.commit();
}
BottomNavigationView navigation = findViewById(R.id.navigation);
BottomNavigationViewHelper.disableShiftMode(navigation); //disabling the shitty shifting mode
navigation.setOnNavigationItemSelectedListener(mOnNavigationItemSelectedListener);
FirstFragment firstFragment = new FirstFragment();
android.support.v4.app.FragmentTransaction fragmentTransactionOne = getSupportFragmentManager().beginTransaction();
fragmentTransactionOne.replace(R.id.content_main, firstFragment, "Fragment one");
fragmentTransactionOne.commit();
}
Here the first activty launches fine i.e MainActivity(). But Click on the second shortcut nothing happens.
Anyone explain me what am i doing wrong?
I see a couple of things that don't look right:
On shortcut.xml:
Both shortcuts should target the 'MainActivity' class, as this is the point of entry and the responsible for adding the fragments to the ui. So, you need to change the targetClass on the second shortcut and target the 'MainActivity' instead.
On the onCreate method:
When the action corresponds to the second shortcut, it sets the second fragment on the screen but the method goes on and sets the first fragment over it.
I guess it should be an if-else:
if (Second.equals(getIntent().getAction())) {
SecondFragment secondFragment = new SecondFragment();
android.support.v4.app.FragmentTransaction fragmentTransactionTwo = getSupportFragmentManager().beginTransaction();
fragmentTransactionTwo.replace(R.id.content_main, secondFragment, "fragment two");
fragmentTransactionTwo.commit();
} else {
FirstFragment firstFragment = new FirstFragment();
android.support.v4.app.FragmentTransaction fragmentTransactionOne = getSupportFragmentManager().beginTransaction();
fragmentTransactionOne.replace(R.id.content_main, firstFragment, "Fragment one");
fragmentTransactionOne.commit();
}
i have same problem like yours, i found how to move to fragment. you should hit the action. put this in onCreate, maybe this will help you
if ("com.xxxxxxx.YourShortcutAction".equals(getIntent().getAction())) {
val fragment = YourFragment()
addFragment(fragment)
}
im using kotlin for android
After some time I found the answer to how to open the fragment via the shortcut Kotlin:
shortcut.xml
<shortcuts xmlns:android="http://schemas.android.com/apk/res/android">
<shortcut
android:shortcutId="mainShortcut"
android:enabled="true"
android:shortcutShortLabel="#string/somestring">
<intent
android:action="xxx.example.workapp.test"
android:targetPackage="xxx.example.workapp"
android:targetClass="xxx.example.workapp.MainActivity">
</intent>
</shortcut>
MainActivity
class MainActivity : AppCompatActivity() {
private lateinit var bottomNav : BottomNavigationView
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.activity_main)
loadFragment(HomeFragment())
if ("xxx.example.workapp.test" == intent.action) {
loadFragment(YourFragment())
}
bottomNav = findViewById(R.id.bottomNav)
bottomNav.setOnItemSelectedListener {
when (it.itemId) {
R.id.homeFragment -> {
loadFragment(HomeFragment())
true
}
R.id.SettingsFragment -> {
loadFragment(SettingsFragment())
true
}
else -> {
false
}
}
}
}
private fun loadFragment(fragment: Fragment){
val transaction = supportFragmentManager.beginTransaction()
transaction.replace(R.id.container,fragment)
transaction.addToBackStack(null)
transaction.commit()
}}
AndroidManifest.xml
...
<activity
android:name=".MainActivity"
android:configChanges="locale"
android:exported="true"
android:screenOrientation="portrait" >

I've created a basic Android app that is intended to have a map with a hamburger drawer on-top of that. Each hamburger menu option will run object methods on the GoogleMap object.
The issue is that while the hamburger drawer is created and works, the map's fragment is placed in the correct place, the onCreate and subsequently onMapReady functions in MainActivity are not running meaning the GoogleMap object is never made. I added some print statements to these functions to make sure and they are never printed.
I've got two classes, HamburgerDrawer.java and MainActivity.java.
HamburgerDrawer.java:

LatLng sydney = new LatLng(-34, 151);
mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney"));
mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
}
}
I have multiple layout xml files to implement the hamburger menu, although the relevant one which contains the content for the drawer is here:
content_hamburger_drawer.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"

android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"
tools:context="com.vanleusen.brighthelp.HamburgerDrawer"
tools:showIn="#layout/app_bar_hamburger_drawer">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Hello World!" />
<FrameLayout
android:layout_width="match_parent"
android:layout_height="match_parent" >
<fragment
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.MapFragment" />
<view
android:id="#+id/myview"
android:layout_width="match_parent"
android:layout_height="fill_parent"
class="android.view.View" />
</FrameLayout>
</RelativeLayout>
And finally I've heard this may be connected to my AndroidManifest although I tried some corrections nothing seemed to work for me, I included this below:
AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>

I'd highly appreciate it if someone could help me work out why my map's onCreate and onMapReady functions are not being executed.
I think you are not calling MainActivity class from anywhere that's why this problem is coming.Please call it from HamburgerDrawer class in onCreate method or any clicklistener.
Intent a=new Intent(getApplicationContext,MainActivity.class);
startActivity(a);
I want to ask for help.
I already created a list of activities in Android Studio.
Each Activity contains a specific item. Those items are different "Departments" in our University.
Example:
Activity 1 = College of Computer Studies;
Activity 2 = College of Teacher Education;
Activity 3 = College of Engineering.
My Spinner contains the departments.
My problem is, if I choose "College in Computer Science" in Spinner and click the "SEND" button, I want Activity 1 to be shown.
Would you help me with the code to do that?
**Spinner in activity_main.xml
<Spinner
android:layout_width="wrap_content"
android:layout_height="wrap_content"

first get your spinner in the main class like this
Spinner spin =(Spinner)findViewById(R.id.spin);
now in your on click method do this
int position =spin.getSelectedItemPosition();
//change the activities with yours
switch (position){
case 0: intent.setClass(Activity1.class,MainActivity.this);
break;
case 1: intent.setClass(Activity2.class,MainActivity.this);
break;
case 2: intent.setClass(Activity3.class,MainActivity.this);
break;
case 3: intent.setClass(Activity4.class,MainActivity.this);
break;
case 4: intent.setClass(Activity5.class,MainActivity.this);
break;
}
startActivity(intent);
I have created in Eclipse a Android default project with navigation drawer.
But my App Icon is not showing on the Action bar. I want to use the min API 9.
I also using appcombat V7 for support library.
Main Activity :
public class MainActivity extends ActionBarActivity implements
NavigationDrawerFragment.NavigationDrawerCallbacks {
/**
* Fragment managing the behaviors, interactions and presentation of the
* navigation drawer.
*/
private NavigationDrawerFragment mNavigationDrawerFragment;
/**
* Used to store the last screen title. For use in
* {#link #restoreActionBar()}.
*/
private CharSequence mTitle;
ActionBar actionBar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Initiate
actionBar = getSupportActionBar();
mNavigationDrawerFragment = (NavigationDrawerFragment) getSupportFragmentManager()
.findFragmentById(R.id.navigation_drawer);
mTitle = getTitle();
// Set up the drawer.
mNavigationDrawerFragment.setUp(R.id.navigation_drawer,
(DrawerLayout) findViewById(R.id.drawer_layout));
}
#Override
public void onNavigationDrawerItemSelected(int position) {
// update the main content by replacing fragments
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager
.beginTransaction()
.replace(R.id.container,
Fragment1.newInstance(position + 1)).commit();
}
public void onSectionAttached(int number) {
switch (number) {
case 1:
mTitle = getString(R.string.title_section1);
break;
case 2:
mTitle = getString(R.string.title_section2);
break;
case 3:
mTitle = getString(R.string.title_section3);
break;
}
}
public void restoreActionBar() {
actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_STANDARD);
actionBar.setDisplayShowTitleEnabled(true);
actionBar.setTitle(mTitle);
// enable ActionBar app icon to behave as action to toggle nav drawer
actionBar.setDisplayHomeAsUpEnabled(true);
actionBar.setHomeButtonEnabled(true);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
if (!mNavigationDrawerFragment.isDrawerOpen()) {
// Only show items in the action bar relevant to this screen
// if the drawer is not showing. Otherwise, let the drawer
// decide what to show in the action bar.
getMenuInflater().inflate(R.menu.main, menu);
restoreActionBar();
return true;
}
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
