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);
