tengo estocajón de navegación que funcionaba perfectamente bien Refactorizando mi código, eliminé todoonOptionsItemSelecteds en actividades e hizo que todas las actividades hereden de una actividad base que se extiendeAppComplatActivity yimplementos Todos los métodos necesarios. Después de hacer clic en el icono de hamburguesa ya no funciona, aunque tengosyncstate() y todo.

¿Alguna pista de por qué esto no funciona?

Una de las actividades:

public class MainActivity extends BaseActivity implements SearchFilterFragment.OnFragmentInteractionListener {

NavigationView navigationView;
DrawerLayout drawerLayout;

private Tracker mTracker;

@Override
protected void onResume() {
    super.onResume();
    drawerLayout.openDrawer(GravityCompat.START);
}

@Override
protected void onPostResume() {
    super.onPostResume();
    mTracker.setScreenName("MainActivity" + "-----");
    mTracker.send(new HitBuilders.ScreenViewBuilder().build());
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    getWindow().getDecorView().setLayoutDirection(View.LAYOUT_DIRECTION_RTL);
    drawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
    drawerLayout.openDrawer(GravityCompat.START);
    navigationView = (NavigationView) findViewById(R.id.navigation_view_primary);
    navigationView.setNavigationItemSelectedListener(new NavigationDrawerListener(this));
    setupToolbar();
    Haftdong application = (Haftdong) getApplication();
    mTracker = application.getDefaultTracker();
}

private void setupToolbar() {
    // Show menu icon
    final ActionBar actionBar = getSupportActionBar();
    actionBar.setDisplayHomeAsUpEnabled(true);// will make the icon clickable and add the < at the left of the icon.
    DrawerLayout mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
    ActionBarDrawerToggle mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
    mDrawerLayout.setDrawerListener(mDrawerToggle);
    mDrawerToggle.syncState();//for hamburger icon
}

@Override
public void onFragmentInteraction(Uri uri) {
}

}

Actividad base:

public class BaseActivity extends AppCompatActivity {

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

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.menu_base, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();
    //noinspection SimplifiableIfStatement
    if (id == R.id.action_settings) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}

}
