在不同活动中使用相同的导航抽屉，工具栏错误

Question

I'm trying to develop an app with multiple activities and the same navigation drawer and toolbar. I've created a BaseActivity for initialization of drawer and other activities extend it, but I have problems with toolbar, in particular when using setSupportActionBar(toolbar).

How can I fix this problem?

BaseActivity.java

    public abstract class BaseActivity extends AppCompatActivity
  implements NavigationView.OnNavigationItemSelectedListener {

private DrawerLayout drawer;
private ActionBarDrawerToggle toggle;

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(getLayoutResourceId());

}

protected abstract int getLayoutResourceId();

public void initDrawer() {

   drawer = (DrawerLayout) findViewById(R.id.drawer_layout);

   Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
   setSupportActionBar(toolbar);


   toggle = new ActionBarDrawerToggle(
            (Activity) this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);

    drawer.setDrawerListener(toggle);
    toggle.setDrawerIndicatorEnabled(true);
    toggle.syncState();

    getActionBar().setDisplayHomeAsUpEnabled(true);
    getActionBar().setHomeButtonEnabled(true);

    NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
    navigationView.setNavigationItemSelectedListener(this);

}

@SuppressWarnings("StatementWithEmptyBody")
@Override
public boolean onNavigationItemSelected(MenuItem item) {
    int id = item.getItemId();

    if (id == R.id.food) {
        final Intent intent = new Intent(this, FoodDiary.class);
        startActivity(intent);
    }

    drawer.closeDrawer(GravityCompat.START);
    return true;
}

}

Answer 1

You can't use same Navigation Drawer and Toolbar with different Activities. If you want different screens with the same components, you have to use Fragments with one Activity, for example FragmentActivity.
