1、自定义一个带按钮的Notification布局:layout_notification;

2、创建Notification:

  RemoteViews views = new RemoteViews(getPackageName(),R.layout.layout_nitification);  //自定义的布局视图

  //按钮点击事件:

  PendingIntent homeIntent = PengdingIntent.getBroadcast(this,1,new Intent("action"),PengdingIntent.FLAG_UPDATE_CURRENT);

  views.setOnClickPendingIntent(R.id.btn,homeIntent);    //点击的id,点击事件

  //创建通知:

    NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(getApplicationContext);

    mBuilder.setContent(views)    //设置布局

        .setOngoing(true)    //设置是否常驻,true为常驻

        .setSmallIcon(R.mipmap.ic_laucher)    //设置小图标

        .setTicker("通知来了")        //设置提示

        .setPriority(Notification.PRIORITY_MAX)  //设置优先级

        .setWhen(System.currentTimeMillis())    //设置展示时间

        .setContentIntent(PendingIntent.getBroadcast(this,2,new Intent("action.view"),PengingIntent.FLAG_UPDATE_CURRENT);    //设置视图点击事件

    NotificationManager mNotificationManager = (NotificationManager)getSystemService(NOTIFICATION_SERVICE);

    mNotificationManager.notify(100,mBuilder.build())    //显示通知: 当前notificationid,当前notification

3、创建NotificationBroadcast接收通知:

public class NotificationBroadcast extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();    //动作
collapseStatusBar(context);        //收起通知栏
Intent i = new Intent(context,MainActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);    //必须添加,避免重复打开
if (action.equals("com.xczl.smart.notification.home")){
i.putExtra("flag","home");    //传值
context.startActivity(i);
}
} 

public void collapseStatusBar(Context context) {
    try {
Object statusBarManager = context.getSystemService("statusbar");
Method collapse;
if (Build.VERSION.SDK_INT <= 16) {
collapse = statusBarManager.getClass().getMethod("collapse");
} else {
collapse = statusBarManager.getClass().getMethod("collapsePanels");
}
collapse.invoke(statusBarManager);
} catch (Exception localException) {
localException.printStackTrace();
}
}

4、MainActivity接收消息:

  覆写 onNewIntent():

@Override
protected void onNewIntent(Intent intent) {
String extra = intent.getStringExtra("flag");
if (!TextUtils.isEmpty(extra)){
if (extra.equals("home")){
//接收到值的具体操作
}
}
}

5、配置清单:

   MainActivity:设置LanchMode为singleTask

   注册Broadcast:

<receiver
android:name="com.xczl.smart.broadcast.NotificationBroadcast"
android:enabled="true">
<intent-filter>
<action android:name="action"/>
<action android:name="action.view"/>
</intent-filter>
</receiver>

     配置通知栏伸缩权限:  

<uses-permission android:name="android.permission.EXPAND_STATUS_BAR"/>
