如何设置导航抽屉从右到左打开？

Question

我需要在xml文件和java文件（如下所示）中进行哪些更改，以便我的导航抽屉从右向左打开？通过使用下面的代码，我的导航抽屉从左到右打开，请建议我需要在我的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"/>
</android.support.v4.widget.DrawerLayout>

Answer 1

设置ListView引力right或end而不是start

android:layout_gravity="right" 

同时将DrawerToggle更新为：

mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
        R.drawable.ic_drawer, R.string.drawer_open,
        R.string.drawer_close) {

    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        if (item != null && item.getItemId() == android.R.id.home) {
            if (mDrawerLayout.isDrawerOpen(Gravity.RIGHT)) {
                // Notice the Gravity.Right 
                mDrawerLayout.closeDrawer(Gravity.RIGHT);
            } else {
                mDrawerLayout.openDrawer(Gravity.RIGHT);
            }
        }
        return false;
    }
};

来自Docs：

  

抽屉视图（ListView）必须使用android：layout_gravity属性指定其水平重力。要支持从右到左（RTL）语言，请使用＆＃34; start＆＃34;指定值。而不是＆＃34;左＆＃34; （所以当布局为RTL时，抽屉会出现在右侧。）

Answer 2

就像vjdhama说的那样简单。添加到上面你将不得不将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"/>

另外，请记住将Gravity.START / Gravity.LEFT的出现更改为Gravity.END / Gravity.Right，如果您使用它来关闭或打开抽屉。玩得开心。 ：）

Answer 3

如果你想在打开之前从按钮添加这个动作，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);
    }
}
});
