Navigation drawer on click issue upon extending activity

So i have extended this DrawerActivity to other activities and I can see the Navigation bar in the extended activities but the on item click listener doesnt work.
This is the drawer activity
public class DrawerActivity extends AppCompatActivity {
public DrawerLayout mDrawarlayout;
public ActionBarDrawerToggle mToggle;
public NavigationView mNavigationView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_drawer);
mDrawarlayout = findViewById(R.id.drawer_layout);
mToggle = new ActionBarDrawerToggle(this, mDrawarlayout, R.string.open, R.string.close);
mDrawarlayout.addDrawerListener(mToggle);
mNavigationView = findViewById(R.id.navigationView);
mToggle.syncState();
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
setupDrawerContent(mNavigationView);
}
public void selectItemDrawer(MenuItem menuItem) {
switch (menuItem.getItemId()) {
case R.id.settings_drawer:
Toast.makeText(getApplicationContext(), "Clicked", Toast.LENGTH_LONG).show();
Intent anIntent = new Intent(getApplicationContext(), PatientSettingsActivity.class);
startActivity(anIntent);
//drawerLayout.closeDrawers();
break;
case R.id.logout:
Toast.makeText(getApplicationContext(), "Logout Clicked", Toast.LENGTH_LONG).show();
break;
case R.id.chat:
Toast.makeText(getApplicationContext(), "CHat Clicked", Toast.LENGTH_LONG).show();
break;
case R.id.history:
Toast.makeText(getApplicationContext(), "Hisotry Clicked", Toast.LENGTH_LONG).show();
break;
case R.id.db:
Toast.makeText(getApplicationContext(), "Dashboard Clicked", Toast.LENGTH_LONG).show();
break;
}
menuItem.setChecked(true);
setTitle(menuItem.getTitle());
mDrawarlayout.closeDrawers();
}
private void setupDrawerContent(NavigationView navigationView) {
navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
selectItemDrawer(item);
return true;
}
});
}
}
This is the drawer activity xml
<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:layout_width="match_parent"
android:layout_height="match_parent"
android:id="#+id/drawer_layout"
tools:context=".DrawerActivity">
<android.support.design.widget.NavigationView
app:headerLayout="#layout/header"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:background="#color/white"
app:itemTextColor="#color/primaryTextColor"
app:menu= "#menu/drawermenu"
android:id="#+id/navigationView"
android:layout_gravity = "start">
</android.support.design.widget.NavigationView>
</android.support.v4.widget.DrawerLayout>
This is how i have extended DrawerActivity
P.S this is what i followed
Same Navigation Drawer in different Activities
public class MapActivity extends DrawerActivity{
........}
And i have noticed that the on item click listener works when i run the DrawerActivity only

I solved my problem by following this tutorial below
http://mateoj.com/2015/06/21/adding-toolbar-and-navigation-drawer-all-activities-android/
and the github link

NavigationDrawerActivity with BottomNavigationActivity

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)
<?xml version="1.0" encoding="utf-8"?>

In my Fragment is the Layout of Mainactivity also shown

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:
MainActivity(Navigation Drawer Templated, I wrote only in the onNavigationItemSelected, so that it goes to the fragment when I click on the first item:

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
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will

}
return super.onOptionsItemSelected(item);

// Handle navigation view item clicks here.
int id = item.getItemId();
if (id == R.id.nav_camera) {

first first = new first();
FragmentManager fragmentManager = getSupportFragmentManager();
fragmentManager.beginTransaction().replace(R.id.fragment, first).commit();

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;

Android navigation drawer icon not working [duplicate]

This question already has an answer here:
Navigation drawer not opening from cutom menu button
(1 answer)
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:
MainActivity.java
//Drawer and fragments variables
private FragmentManager fragmentManager;
private ActionBarDrawerToggle toggle;
private DrawerLayout drawer;
//Searchbar variables
private Toolbar toolbar, searchtollbar;
private Menu search_menu;
private MenuItem item_search;

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//Setup toolbar
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
setSearchtollbar();
//Setup navigationdrawer
drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
toggle = new ActionBarDrawerToggle(this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
drawer.addDrawerListener(toggle);
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
navigationView.getMenu().getItem(0).setChecked(true);
//Setup fragments
fragmentManager = getSupportFragmentManager();
try{
fragmentManager.beginTransaction().replace(R.id.container, HomeFragment.class.newInstance()).commit();
}catch(Exception e){
handleError(e);
}
}
#Override
public void onBackPressed() {

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();

Android GoogleMaps - onMapReady never called

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");
}
