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="123456789@qq.com" />

</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
