NavigationView Folie von rechts

Question

Im mit neuen NavigationView von Android-Support-Design-Bibliothek. Es funktioniert gut, aber wenn ich versuche, es zu setzen Schlitten von der rechten Seite es mit dieser Ausnahme abgestürzt wird:

java.lang.IllegalArgumentException: No drawer view found with gravity LEFT 

Mein Haupt Layout:

<android.support.v4.widget.DrawerLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    android:id="@+id/navigationDrawer" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"> 

    <include layout="@layout/activity_main_content" /> 

    <android.support.design.widget.NavigationView 
     android:id="@+id/navigationView" 
     style="@style/NavigationView" 
     android:layout_width="wrap_content" 
     android:layout_height="match_parent" 
     android:layout_gravity="right" 
     app:headerLayout="@layout/header" 
     app:menu="@menu/menu_drawer"/> 

</android.support.v4.widget.DrawerLayout> 

Kann jemand wissen, wie das ändern? ich versuche, "layout_gravity" zu "end" zu ändern und es gibt mir den gleichen Fehler.

EDIT: voll logcat:

java.lang.IllegalArgumentException: No drawer view found with gravity LEFT

Answer 2

import android.support.v4.widget.DrawerLayout; 
private DrawerLayout drawerLayout; 


drawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout); 
     drawerListener = new ActionBarDrawerToggle(this, drawerLayout, 
       R.drawable.ic_drawer2, R.string.drawer_open, 
       R.string.drawer_close) { 
      @Override 
      public void onDrawerClosed(View drawerView) { 

       Toast.makeText(NavigationDrawerActivity.this, "on drawer close", 
         Toast.LENGTH_SHORT).show(); 
      } 

      @Override 
      public void onDrawerOpened(View drawerView) { 

       Toast.makeText(NavigationDrawerActivity.this, "on drawer open", 
         Toast.LENGTH_SHORT).show(); 
      } 
     }; 
     drawerLayout.setDrawerListener(drawerListener); 


@Override 
    protected void onPostCreate(Bundle savedInstanceState) { 
     super.onPostCreate(savedInstanceState); 
     drawerListener.syncState(); 
    } 

@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(); 
     if(drawerListener.onOptionsItemSelected(item)){ 
      return true; 
     } 


     return super.onOptionsItemSelected(item); 

    } 
@Override 
    public void onConfigurationChanged(Configuration newConfig) { 
     super.onConfigurationChanged(newConfig); 
     drawerListener.onConfigurationChanged(newConfig); 
    } 

Answer 3

<android.support.design.widget.NavigationView 
     android:id="@+id/nav_view" 
     android:layout_width="wrap_content" 
     android:layout_height="match_parent" 
     android:layout_gravity="end" 
     android:fitsSystemWindows="true" 
     app:headerLayout="@layout/nav_header" 
     app:menu="@menu/drawer_view" /> 

Sie sollten sicherstellen, dass android:layout_gravity="end"
