How To Create A Listener For Bottom Navigation And Navigation Drawer In The Same Activity?

//Here is my java code public class HomeActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener { BottomNavigationView bottomNavigationVi

Solution 1:

Answer :

Try the following steps to get it working:

Step1: Implement onNavigationItemSelected as shown below:

.... extendsAppCompatActivityimplementsNavigationView.OnNavigationItemSelectedListener { 

Step2: Use the method generated by the interface as:

@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
    switch (item.getItemId()) {
        caseR.id.your_drawer_item_id:
            ....
            ....
        caseR.id.your_drawer_item_id:
            ....
            ....
    }
}

Step3: In your class declare a Global variable:

public NavigationView navigationView;

Step4: In your onCreate() initialize the variable as:

navigationView = (NavigationView) findViewById(R.id.your_nav_view);

Finally: Setup the navigationView:

navigationView.setNavigationItemSelectedListener(this);

That's it.

Hope it works.

DrawerLayout xml:

Try it.

Solution 2:

You can use on the same activity using a method that recive a MenuItem parameter like this:

privatevoidmyClickItem(MenuItem item){
    switch (item.getItemId()) {
        case R.id.bottom_home:
            // DO SOMETHINGbreak;

        case R.id.drawer_main:
            // DO SOMETHINGbreak;
      }
}

Then, call like this:

BottomNavigationViewbottomNavigationView=  findViewById(R.id.bottom_navigation);
bottomNavigationView.setOnNavigationItemSelectedListener(item -> { // using lamda
     myClickItem(item); //call herereturntrue;
});

NavigationViewnavigationView= findViewById(R.id.nv);
navigationView.setNavigationItemSelectedListener(item -> {
    myClickItem(item); // call the same method here

    drawerLayout.closeDrawers(); // bonus: hide navigation after clickreturnfalse;
});

You don't need to modify your xml res, it'll work fine.
