Sliding Navigation Drawer Not Handling Clicks on Menu Items Android

Sliding navigation drawer not handling clicks on menu items android

Your DrawerLayout's child Views are incorrectly z-ordered. The View for the drawer - in this case, the ListView - needs to be listed last in order to be on top of everything else.

Side Navigation Drawer Item click not working

Just put your NavigationView after FrameLayout. Check below code:

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

            android:theme="@style/CustomTheme.AppBarOverlay">

            <android.support.v7.widget.Toolbar
                android:id="@+id/toolbar"

                android:background="?attr/colorPrimary"
                app:popupTheme="@style/CustomTheme.PopupOverlay" />

        </android.support.design.widget.AppBarLayout>

        <android.support.design.widget.BottomNavigationView

    </FrameLayout>

    <android.support.design.widget.NavigationView
        android:id="@+id/nav_view"
        android:layout_width="wrap_content"
        android:layout_height="match_parent"

Navigation drawer Items not registering click event

The problem is the z ordering. When you expand the list in onDrawerOpened put:

mDrawerList.bringToFront();
mDrawerLayout.requestLayout();

In this post explain the problem and how fix it:

onClick event in navigation drawer

You need to add implements NavigationView.OnNavigationItemSelectedListener

public class MainActivity extends AppCompatActivity implements NavigationView.OnNavigationItemSelectedListener

and add method

@Override
public boolean onNavigationItemSelected(@NonNull MenuItem item) {
    // Handle navigation view item clicks here.
    switch (item.getItemId()) {

       case R.id.nav_maths: {
      //do somthing
            break;
        }  
    }
    //close navigation drawer
    mDrawerLayout.closeDrawer(GravityCompat.START);
    return true;
}

method to set Listener

private void setNavigationViewListener() {
    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);
}

call method in onCreate()

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setNavigationViewListener()
}

My navigation Drawer not close after I click the menu item?

put this line:

mDrawerLayout.closeDrawer(GravityCompat.START);

after:

navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {
            @Override
            public boolean onNavigationItemSelected(@NonNull MenuItem item) {
                int id=item.getItemId();
     /*-------------------HERE--------------------*/
