android的左右侧滑菜单实现

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
