根据这份文件,它没有说明是否可以从右侧实施抽屉.它甚至可能吗？:(

我打算建一个Persian app (RTL).我的应用程序包括ListView和导航抽屉.

我Manifest在应用程序标签中添加了android:supportsRtl="true"

并在onCreate()方法中:getWindow().getDecorView().setLayoutDirection(View.LAYOUT_DIRECTION_RTL);

我知道,LayoutDirection不到17 api不起作用.

对于api等级17及更高:

对于api低于17:

我该如何解决这个问题.1-设置一个conditional statement检查android api并指定一个特定的布局？layout-ldrtleclipse中的2用文件夹？3 - ......？什么是最好的方法？？

如何从DrawerLayout格式从右到左滑动ExpandableListView

我想在屏幕的右下角显示ExpandableListView,我该怎么做？

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

    <FrameLayout
        android:id="@+id/content_frame"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <ExpandableListView
        android:id="@+id/left_drawer"
        android:layout_width="240dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:choiceMode="singleChoice"
        android:divider="@android:color/white"
        android:dividerHeight="0dp"
      />
</android.support.v4.widget.DrawerLayout>

我正在使用最新版本的Android Studio(1.5),我想使用抽屉布局制作一个菜单,以便调用GravityCompat.

我正在尝试使用这些组件并对其进行修改,将Drawer从右向左放置.这是我的代码.

public class MainActivity extends AppCompatActivity
    implements NavigationView.OnNavigationItemSelectedListener {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    ActionBarDrawerToggle toggle = new ActionBarDrawerToggle(
            this, drawer, toolbar, R.string.navigation_drawer_open, R.string.navigation_drawer_close);
    drawer.setDrawerListener(toggle);
    toggle.syncState();

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

@Override
public void onBackPressed() {
    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    if (drawer.isDrawerOpen(GravityCompat.END)) {
        drawer.closeDrawer(GravityCompat.END);
    } else {
        super.onBackPressed();
    }
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this …
