I have a navigation drawer layout with a map fragment in the content. The problem is the onMapReady is never called.
I need reference or initialize the map in the class that handle the navigation drawer? Like call getMapAsync in PrincipalActivity class?
Map:
public class MapaActivity extends FragmentActivity implements OnMapReadyCallback {
private GoogleMap mapa;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.content_principal);
// Obtain the SupportMapFragment and get notified when the mapa is ready to be used.
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
Log.d("Test1", "Here");
mapFragment.getMapAsync(this);
}
#Override
public void onMapReady(GoogleMap googleMap) {
mapa = googleMap;
Log.d("Test2", "Here");
}

I have made a toolbar and Navigation Drawer java class along with its XML, it works perfectly.
Here is the code:
Java:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_navigation);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar1);
setSupportActionBar(toolbar);
//This part is new for NavigationDrawer:
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.addDrawerListener(toggle);
toggle.syncState();
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.items, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.ticket:
startActivity(new Intent(NavigationActivity.this, TicketMasterActivity.class));
break;
case R.id.recipe:
Intent goToRecipe = new Intent(NavigationActivity.this, RecipeSearchActivity.class);
startActivity(goToRecipe);
break;
case R.id.covid:
Intent goToCovid = new Intent(NavigationActivity.this, MainActivity_covid.class);
startActivity(goToCovid);
break;
case R.id.album:

startActivity(goToAlbum);
break;

alertDialogBuilder.setTitle(R.string.WelcomeTotal);
alertDialogBuilder.setMessage(R.string.WelcomeTotalMessage);
alertDialogBuilder.setPositiveButton("OK", (click2, arg) -> {
});
alertDialogBuilder.create().show();
}
return true;
}
#Override
public boolean onNavigationItemSelected(MenuItem item) {
// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.ticket1) {
startActivity(new Intent(NavigationActivity.this, TicketMasterActivity.class));
} else if (id == R.id.recipe1) {
Intent goToRecipe = new Intent(NavigationActivity.this, RecipeSearchActivity.class);
startActivity(goToRecipe);

I want to make it so that every activity uses this specific toolbar. And that every toolbar is preloaded with the items that I put inside in the java class. Is this possible and if so, how?
Thank you.
Create and Activity which will behave as a Parent Activity with your own custom toolbar.
Extend that activity where ever you want.
I am trying to use NavigationDrawerActivity with a BottomNavigationActivity.
I have implemented NavigationDrawerActivity(Separate) first and saved BottomNavigationActivity(Separate) in HomeActivity but a black screen comes out while running app, with no errors!
My HomeActivity
public class HomeActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener{
private DrawerLayout drawerLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
NavigationView navigationView = findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(this, drawerLayout, toolbar,
R.string.navigation_drawer_open, R.string.navigation_drawer_close){
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (item != null && item.getItemId() == android.R.id.home) {
if (drawerLayout.isDrawerOpen(Gravity.RIGHT)) {
drawerLayout.closeDrawer(Gravity.RIGHT);
}
else {
drawerLayout.openDrawer(Gravity.RIGHT);
}
}
return false;
}
};
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,
new HomeFragment()).commit();
navigationView.setCheckedItem(R.id.home);
}
}
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem menuItem) {
switch (menuItem.getItemId()) {
case R.id.search:
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,
new SearchFragment()).commit();
break;
case R.id.home:
getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,
new HomeFragment()).commit();
break;
}
drawerLayout.closeDrawer(GravityCompat.END);
return true;
}
}
Code for My HomeFragment consisting BottomNavigationView
public class HomeFragment extends Fragment {
View view;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_home, container, false);
BottomNavigationView bottomNav = view.findViewById(R.id.bottom_navigation);
bottomNav.setOnNavigationItemSelectedListener(navListener);
getActivity().getSupportFragmentManager().beginTransaction().replace(R.id.fragment_container,
new HomeFragment()).commit();
return view;
}
private BottomNavigationView.OnNavigationItemSelectedListener navListener =
new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
Fragment selectedFragment = null;
switch (item.getItemId()) {
case R.id.tours:
selectedFragment = new ToursFragment();
break;
case R.id.hotel:
selectedFragment = new HotelFragment();
break;
case R.id.maps:
selectedFragment = new SearchFragment();
break;
}
FragmentTransaction transaction = getActivity().getSupportFragmentManager().beginTransaction();
transaction.replace(R.id.content, selectedFragment);
transaction.commit();
return true;
}
};
}
I wanted to use Navigation Drawer Activity with BottomNavigationActivity in this code and wanted to show BottomNavigationActivity in only one fragment.
I solved this problem, but first we forget HomeFragment, I deleted almost everything except View there.
I put BottomNavigationActivity with Navigation Drawer Activity in one Activity
Here is my xml from HomeActivity (i.e. it is MainActivity)

I'm working the first time with Fragments, so sorry if I did smt very stupid :D
I have a Navigation Drawer Activity. When I click in it on the first item i want to open a Fragment. When I open it, there is not only the Layout of the Fragment shown, but also the layout of my MainActivity, it looks very strange.
[1]: https://i.stack.imgur.com/iqTAq.png MainActivity
[2]: https://i.stack.imgur.com/kULQY.png Navigation Drawer
[3]: https://i.stack.imgur.com/T2vDJ.png First Fragment
How can I solve the problem?
Here is my code if you need it:

fab.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
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();
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();
}
}
#Override

getMenuInflater().inflate(R.menu.main, menu);
return true;
}

I hope someone can help me :)
Add a background to your fragment layout, it should solve your problem.
<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"
android:background="#color/white" //Your background color
tools:context="com.gsr.fragmenttest.first">
<!-- TODO: Update blank fragment layout -->
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent">
...
I think the problem is in your activity layout
<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>
</android.support.v4.widget.DrawerLayout>
try to change your main activity layout like above. Hope it will solve your problem.
1) implements first.OnOnFragmentInteractionListener
2) in onNavigationItemSelected method put this code
if (id == R.id.nav_camera) {
setTitle("First Fragment");
first first = new first();
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.fragment, new first()).commit();
3)In first fragment use this line
import android.app.Fragment;

Navigation drawer not opening from cutom menu button

Closed 5 years ago.
I had a working navigation drawer, but I changed the toolbar, and now the icon of the navigationdrawer stopped working. It works again after pulling the drawer out. This is the relevant code:

Now my questions are:
Why doesn't the hamburger icon work the first time?
Why does it start working after pulling the navigation drawer out?
Thanks in advance.
Use This code :
ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
this, mDrawerLayout, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
toggle.setDrawerIndicatorEnabled(false); //disable "hamburger to arrow" drawable
toggle.setHomeAsUpIndicator(R.drawable.menu); //set your own
// setting click listener on hamburger icon
toolbar.setNavigationOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
mDrawerLayout.openDrawer(Gravity.START);
}
}
});
// setting listerner on drawer
mDrawerLayout.addDrawerListener(toggle);
toggle.syncState();
after setting drawer listener add toggle sync and check
drawer.addDrawerListener(toggle);
toggle.syncState();
I have created a Navigation Drawer "BaseActivity" to be extended by multiple activities however when I open the Navigation Drawer none of the menu items can be clicked, there is a semi-opaque layer over them which suggests to me the z-order in which they are loaded is incorrect. How would I go about fixing this?

If the problem is with the Z-index as you said, then you can make it always on top using bringToFront() call this method to your DrawerLayout or NavigationView!
