I have three Fragments that I am trying to display by clicking the appropriate option from a Navigation Drawer. I have the Navigation Drawer displaying and opening/closing fine. But I can't get any of the Fragments to display in the Activity. The main screen just stays blank whenever I click an option. There are no compilation errors. I am new to Android development and also Java dev, and I've been trying to complete this project for a month so it will be finished as soon as I can get this to work. You may see some instances of redundant code, because I just wanted to try anything that could work and I am not sure what to delete, so any clarification on that would help too.
The Fragments should be displayed as results in a RecyclerView.

public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener {
private DrawerLayout mDrawer;

I have two other Fragments that I set up a little differently but just showing the one for ATMs because I feel it is the closest to working.

In MainActivity, I've created a DrawerLayout and ActionBar. Is there any way to use that same Drawer and ActionBar in other activities without writing the same code again? Here's the code I'm using:

android:layout_gravity="start"
app:headerLayout="#layout/header"
app:menu="#menu/drawer_menu"></com.google.android.material.navigation.NavigationView>
</androidx.drawerlayout.widget.DrawerLayout>
Main Java (I've Removed The Extra Code [Non Drawer-Actionbar Code]):
DrawerLayout drawerLayout;
Toolbar toolbar;
TextView json;
RequestQueue requestQueue;
ActionBarDrawerToggle actionBarDrawerToggle;
private RequestQueue mqueue;
private RecyclerView recyclerView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mqueue = Volley.newRequestQueue(this);
setuptools();
setUpToolbar();
}
private void setUpToolbar()
{
drawerLayout = (DrawerLayout) findViewById(R.id.drawer);
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
actionBarDrawerToggle = new ActionBarDrawerToggle(this,drawerLayout,toolbar,R.string.app_name,R.string.app_name) ;
drawerLayout.addDrawerListener(actionBarDrawerToggle);
actionBarDrawerToggle.syncState();
toolbar.setNavigationIcon(R.drawable.ic_menu);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.right_menu,menu);
final MenuItem awesomeMenuItem = menu.findItem(R.id.notification_iconmain);
View awesomeActionView = awesomeMenuItem.getActionView();
awesomeActionView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
onOptionsItemSelected(awesomeMenuItem);
}
});
final TextView not_num = (TextView) menu.findItem(R.id.notification_iconmain).getActionView().findViewById(R.id.hotlist_hot);
String username = Settings.Secure.getString(getContentResolver(), Settings.Secure.ANDROID_ID);
String server_url = "https://google.com/api/notifications.php?username="+username;
JsonObjectRequest request = new JsonObjectRequest(Request.Method.GET, server_url, null,
new Response.Listener<JSONObject>() {
#Override
public void onResponse(JSONObject response) {
try {
JSONArray jsonArray = response.getJSONArray("results");
for (int i = 0; i < jsonArray.length(); i++) {
JSONObject notification_numbers = jsonArray.getJSONObject(i);
String final_num = notification_numbers.getString("notifications");
if(final_num.equals("0")){
}else{
not_num.setVisibility(View.VISIBLE);
not_num.setText(final_num);
}
}
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
}
}
);
mqueue.add(request);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if(id == R.id.notification_iconmain){
Intent intent_noti = new Intent(this, NotificationsPage.class);
this.startActivity(intent_noti);
}
if(id == R.id.user_icon){
Intent intent_user = new Intent(this, Profile_Page.class);
this.startActivity(intent_user);
}
return super.onOptionsItemSelected(item);
}
}
What It Does:
It creates a slider drawer, an action bar with the right side menu, and displays the notification count on Bell Icon, and each item has its custom on-click event.
Now, how I can use the same drawer, action bar without writing the code again and again in each activity.
Menu Item click not working I tried various things but it won't work.
Here are my code:

When I try to view activity_home.xml as a design it will not showing left drawer but when I install the app on device it will show the left drawer on click but when I click on any time it will not showing check able box and not working.
Update These lines of code works for me.. after update clean and rebuild Project.
NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
navigationView.setNavigationItemSelectedListener(this);
navigationView.bringToFront();
Here is a simple solution to address this issue. You can just link your HomeActivity methods to the menu items (whichever you want to). Now just create your methods and go to the menu layout. In the menu layout just add the android:onClick inside the item tag and put the particular method name inside it. And you are done. Let me know if this was useful.

I tried all thing but not getting proper way to implement.Any suggestion how to correct this will be helpful
Hiho!
I build a navigation drawer into my android app. I used the howto from http://blog.teamtreehouse.com/add-navigation-drawer-android and modified it at one place of the layout. I can activate the menu when i touch and swing my finger from left to right. But if I touch the hamburger menu nothing hapend. What ist wrong?
If i swipped in the menu the icon changed to an arrow, so there is a connection.
Hope some one can help me.
