Android中DrawerLayout实现侧滑菜单效果

众所周知，android里面我们很熟悉的一个功能，侧滑菜单效果在以前我们大部分都是用的slidingmenu这个开源框架，自从谷歌官方新出的一个drawerlayout控件之后，越来越多的应用开始使用谷歌的官方的控件写这个效果了。
话不多说，先来发图以表我滴诚意：

开始写代码

drawerlayout 是v4包里面的，所以项目里面需要添加v4包，具体怎么添加就不多说了，
navigationview需要在build.gradle里面添加compile ‘com.android.support:design:25.1.0'

activity_main.xml

<android.support.v4.widget.drawerlayout xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:app="http://schemas.android.com/apk/res-auto"
 xmlns:tools="http://schemas.android.com/tools"
 android:id="@+id/drawer_layout"
 android:layout_width="match_parent"
 android:layout_height="match_parent"
 android:fitssystemwindows="true"
 tools:opendrawer="start">

 <!-- 右边视图 -->
 <include
 layout="@layout/app_bar_main"
 android:layout_width="match_parent"
 android:layout_height="match_parent" />

 <!-- 左边菜单 -->
 <android.support.design.widget.navigationview
 android:id="@+id/nav_view"
 android:layout_width="wrap_content"
 android:layout_height="match_parent"
 android:layout_gravity="start"
 android:fitssystemwindows="true"
 app:headerlayout="@layout/nav_header_main"
 app:menu="@menu/activity_main_drawer" />

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

然后在res文件夹里面添加一个menu菜单文件夹，已经添加的就不用添加了

上面的代码里面navigationview里面有个 app:menu=”@menu/activity_main_drawer”对应如下:
添加一个菜单文件，名字随意，我的是activity_main_drawer.xml

activity_main_drawer.xml

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">

 <group android:checkablebehavior="single">
 <item
  android:id="@+id/nav_camera"
  android:icon="@drawable/ic_menu_camera"
  android:title="第一行" />
 <item
  android:id="@+id/nav_gallery"
  android:icon="@drawable/ic_menu_gallery"
  android:title="第二行" />
 <item
  android:id="@+id/nav_slideshow"
  android:icon="@drawable/ic_menu_slideshow"
  android:title="第三行" />
 <item
  android:id="@+id/nav_manage"
  android:icon="@drawable/ic_menu_manage"
  android:title="第四行" />
 </group>

 <item android:title="communicate">
 <menu>
  <item
  android:id="@+id/nav_share"
  android:icon="@drawable/ic_menu_share"
  android:title="第五行" />
  <item
  android:id="@+id/nav_send"
  android:icon="@drawable/ic_menu_send"
  android:title="第六行" />
 </menu>
 </item>

</menu>

再添加一个布局

上面的代码里面app:headerlayout=”@layout/nav_header_main”对应如下:
添加一个布局，名字是nav_header_main.xml

nav_header_main.xml

<?xml version="1.0" encoding="utf-8"?>
<linearlayout xmlns:android="http://schemas.android.com/apk/res/android"
 xmlns:app="http://schemas.android.com/apk/res-auto"
 android:layout_width="match_parent"
 android:layout_height="@dimen/nav_header_height"
 android:background="@drawable/side_nav_bar"
 android:gravity="bottom"
 android:orientation="vertical"
 android:paddingbottom="@dimen/activity_vertical_margin"
 android:paddingleft="@dimen/activity_horizontal_margin"
 android:paddingright="@dimen/activity_horizontal_margin"
 android:paddingtop="@dimen/activity_vertical_margin"
 android:theme="@style/themeoverlay.appcompat.dark">

 <imageview
 android:id="@+id/imageview"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:paddingtop="@dimen/nav_header_vertical_spacing"
 app:srccompat="@android:drawable/sym_def_app_icon" />

 <textview
 android:layout_width="match_parent"
 android:layout_height="wrap_content"
 android:paddingtop="@dimen/nav_header_vertical_spacing"
 android:text="哈哈哈"
 android:textappearance="@style/textappearance.appcompat.body1" />

 <textview
 android:id="@+id/textview"
 android:layout_width="wrap_content"
 android:layout_height="wrap_content"
 android:text="[e-mail]" />

</linearlayout>

mainactivity：

public class mainactivity extends baseactivity implements navigationview.onnavigationitemselectedlistener {

 private linearlayout right;
 private navigationview left;
 private boolean isdrawer=false;
 private drawerlayout drawer;



 @override
 public int getlayoutid() {
 return r.layout.activity_main;
 }

 @override
 public void initpresenter() {

 }

 @override
 public void initview() {
 drawer = (drawerlayout) findviewbyid(r.id.drawer_layout);


 right = (linearlayout) findviewbyid(r.id.right);
 left = (navigationview) findviewbyid(r.id.nav_view);

 navigationview navigationview = (navigationview) findviewbyid(r.id.nav_view);
 navigationview.setnavigationitemselectedlistener(this);

 right.setontouchlistener(new view.ontouchlistener() {
  @override
  public boolean ontouch(view view, motionevent motionevent) {
  if(isdrawer){
   return left.dispatchtouchevent(motionevent);
  }else{
   return false;
  }
  }
 });
 drawer.setdrawerlistener(new drawerlayout.drawerlistener() {
  @override
  public void ondrawerslide(view drawerview, float slideoffset) {
  isdrawer=true;
  //获取屏幕的宽高
  windowmanager manager = (windowmanager) getsystemservice(context.window_service);
  display display = manager.getdefaultdisplay();
  //设置右面的布局位置 根据左面菜单的right作为右面布局的left 左面的right+屏幕的宽度（或者right的宽度这里是相等的）为右面布局的right
  right.layout(left.getright(), 0, left.getright() + display.getwidth(), display.getheight());
  }
  @override
  public void ondraweropened(view drawerview) {}
  @override
  public void ondrawerclosed(view drawerview) {
  isdrawer=false;
  }
  @override
  public void ondrawerstatechanged(int newstate) {}
 });


 }



 @override
 public void onbackpressed() {
 if (drawer.isdraweropen(gravitycompat.start)) {
  drawer.closedrawer(gravitycompat.start);
 } else {
  super.onbackpressed();
 }
 }




 @suppresswarnings("statementwithemptybody")
 @override
 public boolean onnavigationitemselected(menuitem item) {
 // handle navigation view item clicks here.
 int id = item.getitemid();

 if (id == r.id.nav_camera) {
  // handle the camera action
 } else if (id == r.id.nav_gallery) {

 } else if (id == r.id.nav_slideshow) {

 } else if (id == r.id.nav_manage) {

 } else if (id == r.id.nav_share) {

 } else if (id == r.id.nav_send) {

 }

 drawerlayout drawer = (drawerlayout) findviewbyid(r.id.drawer_layout);
 drawer.closedrawer(gravitycompat.start);
 return true;
 }

drawer.opendrawer(gravitycompat.start);//打开滑动菜单

drawer.closedrawer(gravitycompat.start);//关闭滑动菜单

drawer.isdraweropen(gravitycompat.start);//判断滑动菜单是否打开
