最近看了很多app应用都采用的是左右侧滑，比如网易新闻、凡客等
这里也试着写一下侧滑
首先看一下效果
然后给出xml布局代码
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity" >
<LinearLayout
android:id="@+id/layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<LinearLayout
android:id="@+id/leftMenu"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/left_text" />
</LinearLayout>
<LinearLayout
android:id="@+id/content"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<RelativeLayout
android:layout_width="fill_parent"
android:id="@+id/layout01"
android:layout_height="wrap_content"
android:background="@drawable/bg_title"
android:layout_alignParentTop="true"
android:gravity="center"
android:orientation="horizontal">
<ImageView
android:id="@+id/leftBtn"
android:layout_alignParentLeft="true"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:padding="10dp"
android:src="@drawable/home_category"/>
<ImageView
android:id="@+id/leftIcon"
android:layout_toRightOf="@+id/leftBtn"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:src="@drawable/title_icon_line"/>
<TextView
android:id="@+id/home_resource"
android:text="@string/app_name"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textColor="@color/white"
android:textSize="@dimen/title_size"
android:textStyle="bold"
android:padding="10dp"
android:gravity="center"/>
<ImageView
android:id="@+id/rightIcon"
android:layout_toLeftOf="@+id/rightBtn"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:src="@drawable/title_icon_line"/>
<ImageView
android:id="@+id/rightBtn"
android:padding="10dp"
android:layout_alignParentRight="true"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:src="@drawable/home_myvancl"
/>
</RelativeLayout>
</LinearLayout>
<LinearLayout
android:id="@+id/rightMenu"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/right_text" />
</LinearLayout>
</LinearLayout>
</RelativeLayout>
接着写Activity
