185.m1-DrawerLayout的应用

首先布局文件activity_main.xml布局是由android.support.v4.widget.DrawerLayout开始，然后里面一个线性布局一个FrameLayout

<android.support.v4.widget.DrawerLayout 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" 
    android:id="@+id/dl">

	<LinearLayout 
	    android:layout_width="match_parent"
    	android:layout_height="match_parent"
	    >
	    
	    <TextView 
	        android:layout_width="wrap_content"
    		android:layout_height="wrap_content"
    		android:text="asd"
	        />
	</LinearLayout>
	<!-- 抽屉 -->
    <FrameLayout 
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@drawable/bg_tab"
        android:layout_gravity="left">
        
    </FrameLayout>

</android.support.v4.widget.DrawerLayout>

逻辑代码MainActivity.java实现了滑动的抽屉效果，同时实现了Home图标的点击的抽屉效果

点击的抽屉效果的时候需要让图标显示，同时作为按钮可见

/让拉出显示详情的图片显示，可以拉出详情
actionBar.setDisplayHomeAsUpEnabled(true);
//让按键点击有效
actionBar.setHomeButtonEnabled(true);

需要让ActionBar和开关建立关系

//  让开关和actionbar建立关系 
drawerToggle.syncState();

同时由于ActionBar也会处理点击事件，因此需要在ActionBar将点击事件抛出之前处理图标的点击事件

//优先处理drawerToggle的点击，drawerToggle出不不了交给父类
return drawerToggle.onOptionsItemSelected(item)|super.onOptionsItemSelected(item);

全部代码如下
