Android 如何设置从右向左打开导航抽屉？

为了让导航抽屉从右向左打开，我需要在下面给出的xml文件和java文件中做哪些更改？通过使用下面的代码，我的导航抽屉将从左到右打开，请建议我需要在xmml代码和java代码中进行哪些更改

activity_main.xml：

<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" />

<ListView
    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/transparent"
    android:dividerHeight="0dp"
    android:background="#ffff"/>

将ListView重力设置为右或结束而不是开始

同时将抽屉切换更新为：

发件人：

列表视图的抽屉视图必须使用android:layout\u gravity属性指定其水平重力。要支持从右到左的RTL语言，请使用start而不是left指定值，以便在布局为RTL时抽屉显示在右侧

就像维德哈马说的那样简单。添加到上面，您必须将ListView更改为下面

<ListView
    android:id="@+id/left_drawer"
    android:layout_width="240dp"
    android:layout_height="match_parent"
    android:layout_gravity="end" //change this, you can also use **right**
    android:choiceMode="singleChoice"
    android:divider="@android:color/transparent"
    android:dividerHeight="0dp"
    android:background="#ffff"/>

---

此外，如果您要使用Gravity.START/Gravity.LEFT关闭或打开抽屉，请记住将其发生位置更改为Gravity.END/Gravity.Right。玩得开心

如果要在按钮打开之前添加此操作，我找到了一个解决方案：

toolbar = (Toolbar) findViewById(R.id.tool_bar);
Drawer = (DrawerLayout) findViewById(R.id.DrawerLayout);
mDrawerToggle = new   ActionBarDrawerToggle(this,Drawer,toolbar,R.string.openDrawer,R.string.closeDrawer){

@Override
public void onDrawerOpened(View drawerView) {
    super.onDrawerOpened(drawerView);
}
@Override
public void onDrawerClosed(View drawerView) {
    super.onDrawerClosed(drawerView);
}
}; // Drawer Toggle Object Made
Drawer.setDrawerListener(mDrawerToggle);
mDrawerToggle.syncState();               
toolbar.setNavigationOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View v) {
    if (Drawer.isDrawerOpen(Gravity.RIGHT)) {
        Drawer.closeDrawer(Gravity.RIGHT);
    } else {
        Drawer.openDrawer(Gravity.RIGHT);
    }
}
});

更改您的ListView android:layout\u gravity！更改您的ListView android:layout\u gravity！我已将GravityCompat.START更改为GravityCompat.END，android:layout\u gravity=START更改为android:layout\u gravity=END，但我仍然没有在模拟器中获得所需的结果。我是否需要在java代码中进行进一步更改。我想你已经得到了答案：我在代码中提到要替换相同的，但我只提到了Gravity.START.：我将GravityCompat.START改为GravityCompat.END，android:layout\u Gravity=START改为android:layout\u Gravity=END，但我仍然没有在模拟器中得到想要的结果。我是否需要在java代码中做进一步的更改。我猜你得到了答案：我在代码中提到要替换相同的，但我只提到了Gravity.START.：我已经将android:layout\u Gravity=start更改为android:layout\u Gravity=end，但我仍然没有在模拟器中获得所需的结果。我是否需要在java代码中进行更改。我已经将android:layout\u Gravity=start更改为android:layout\u Gravity=end，但仍然没有获得所需的结果我的模拟器。我是否需要在java代码中进行更改。
