相同的抽屉在不同的活动，工具栏错误

Question

我试图开发一个应用程序与多个活动和相同的导航抽屉和工具栏。 我创建了一个BaseActivity，用于初始化抽屉和其他活动扩展它，但是我遇到了工具栏问题，特别是在使用setSupportActionBar（工具栏）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; 
} 

} 

activity_main.xml中

<?xml version="1.0" encoding="utf-8"?> 
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools"

     app:popupTheme="@style/AppTheme.PopupOverlay" /> 

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


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

FoodDiary.java

public class FoodDiary extends BaseActivity { 

     @Override 
     protected int getLayoutResourceId() { 
     return R.layout.content_fooddiary; 
     } 

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

content_fooddiary.xml

<?xml version="1.0" encoding="utf-8"?> 
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
     xmlns:tools="http://schemas.android.com/tools"

     android:orientation="vertical" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:paddingBottom="@dimen/activity_vertical_margin" 
     app:layout_behavior="@string/appbar_scrolling_view_behavior" 

    <Space 
     android:layout_width="wrap_content" 
     android:layout_height="match_parent" 
     android:layout_weight="0.5"/> 

    <ImageView 
     android:layout_width="30dp" 
     android:layout_height="match_parent" 
     android:id="@+id/imageView" 
     android:src="@drawable/left2"/> 

    </LinearLayout>

不能使用相同的抽屉式导航栏和工具栏与不同的活动。 如果您想要使用相同组件的不同屏幕，则必须将Fragments与一个Activity一起使用，例如FragmentActivity。
