Question

我是Android开发的新手，想知道一些事情。我正在为我的应用程序使用导航抽屉，但它在左侧。我想知道是否有办法让它在右侧以及如何。

activity_home.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" >

<!-- The main content view -->

<FrameLayout
    android:id="@+id/content_frame"

    android:layout_width="match_parent"
    android:layout_height="match_parent" />
<!-- The navigation drawer -->

<ListView

    android:id="@+id/drawer_list"
    android:layout_width="240dp"
    android:layout_height="match_parent"
    android:layout_gravity="start"
    android:background="#111"
    android:choiceMode="singleChoice"
    android:divider="@android:color/transparent"
    android:dividerHeight="0dp" />

drawer_list_item.xml

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceListItemSmall"
android:gravity="center_vertical"
android:paddingLeft="16dp"
android:paddingRight="16dp"

android:textColor="#fff"
android:background="?android:attr/activatedBackgroundIndicator"
android:minHeight="?android:attr/listPreferredItemHeightSmall"/>

fragment_layout.xml

<?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >

<WebView
    android:id="@+id/webView"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

正如文件所述：

http://developer.android.com/reference/android/support/v4/widget/DrawerLayout.html

使用子视图上的android：layout_gravity属性控制抽屉定位和布局，该属性对应于您希望抽屉出现的视图的哪一侧：左侧或右侧。（或者在支持布局方向的平台版本上开始/结束。）

所以是的，你可以使用android:layout_gravity属性将它放在右边：）

屏幕右侧的抽屉？
