Android Slide Menu Drawerlayout (drawer layout) Implementation

Application Scenarios:because the side-slip menu has a better user experience effect, so more apps use the slide-down Drawer menu list, such as NetEase client, Baidu AV, Iqiyi art and so on. At this point, the slide-by menu has more usage requirements.
Knowledge Point Introduction:There are many ways to implement the side-by-Side menu function, if open source project Slidingmenu, for Https://github.com/jfeinstein10/SlidingMenu. The open source project relies on another open source project, Actionbarsherlock, for Https://github.com/JakeWharton/ActionBarSherlock. This way of realization, the reader can usually have time to study on their own. This example mainly introduces the support provided by Android-support-v4.jar, Android.support.v4.widget.DrawerLayout, which is compatible with the lower version of the system.
How to use:First step: Create a new test project Drawerlayout.
The second step: write the related layout file, the main interface layout file activity_main.xml.

<linearlayout 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 "Android:orien tation= "Vertical" tools:context= ".

the layout file for the fragment class Layout_first.xml,layout_next.xml. "Layout_first.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:o rientation= "vertical" >    <textview         android:layout_width= "match_parent"        android:layout_height= " 20DP "        android:text=" firstfragment "        android:id=" @+id/texttextview "/>    <linearlayout android: Layout_width= "Match_parent"        android:layout_height= "wrap_content"        android:orientation= "vertical" >        <listview android:layout_height= "wrap_content"            android:layout_width= "Wrap_content"            android: Cachecolorhint= "#FFFFFF"            android:id= "@+id/firstfragmentlistview" >        </ListView>    </ Linearlayout></linearlayout>

"Layout_next.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:o rientation= "vertical" >    <textview         android:layout_height= "wrap_content"        android:layout_width= " Match_parent "        android:text=" Nextfragment "/></linearlayout>

The listitem layout file for the ListView is Main_listitem.xml.
"Main_listitem.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:o rientation= "vertical" >    <textview android:layout_width= "match_parent"        android:layout_height= "40DP"        android:id= "@+id/menu"        android:textsize= "20DP"        android:gravity= "center_vertical"        android:text = "Loading ..."/></linearlayout>

The second step: write the relevant Java files, Firstfragment.java, Nextfragment, Mainactivity.java, Menulistviewadapter.java, Databuiltutils.java.
"Firstfragment.java"
