不同活动中的相同导航抽屉，工具栏错误

Question

我正在尝试开发具有多个活动和相同导航抽屉和工具栏的应用程序。我已经创建了一个 BaseActivity 用于抽屉初始化和其他活动扩展它，但我在工具栏上遇到问题，特别是在使用 setSupportActionBar(toolbar) 时。

我该如何解决这个问题？

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;
}

}

您不能对不同的 Activity 使用相同的导航抽屉和工具栏。如果您想要具有相同组件的不同屏幕，则必须使用具有一个 Activity 的 Fragment，例如 FragmentActivity.
