NavigationView 从右侧滑动

Question

我正在使用来自 android 支持设计库的新 NavigationView。它工作正常，但是当我尝试设置它从右侧滑动时，它会因该异常而崩溃：

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

我的主要布局：

<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>

谁能知道如何改变这个？我尝试将“layout_gravity”更改为“end”，这给了我同样的错误。

    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" />

你应该确保android:layout_gravity="end"
