android Notification与BroadcastReceiver结合使用

1. NotificationUtils 类

public class NotificationUtils {    private static final String TAG = "NotificationUtils";    static int i = 0;    private static  int id = 1;    public static void setNotification(Context context, String content,String toUserId ) {//        Intent intent = new Intent(Intent.ACTION_MAIN);//        intent.addCategory(Intent.CATEGORY_LAUNCHER);//        intent.setClass(MyApplication.getInstance(), MainActivity.class);//        RxBus.getDefault().post(Constants.NOTIFICATION);        MilierLog.i(TAG,"setNotification***");        Intent intent = new Intent(MyApplication.getInstance(), NotificationClickReceiver.class);        intent.setAction("notification_clicked");        intent.putExtra(NotificationClickReceiver.TYPE, id);        MilierLog.i(TAG,"通知里toUserId is :"+toUserId);        Constants.TO_USER_ID = toUserId;        intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_RESET_TASK_IF_NEEDED);//        PendingIntent pendingIntent = PendingIntent.getActivity(context, 0, intent, 0);        PendingIntent pendingIntent = PendingIntent.getBroadcast(MyApplication.getInstance(), id++, intent, PendingIntent.FLAG_UPDATE_CURRENT);        NotificationManager notificationManager = (NotificationManager) context.getSystemService(context.NOTIFICATION_SERVICE);        Notification.Builder builder = new Notification.Builder(context);//        if (content.equals(context.getString(R.string.newMessage))) {//            builder.setContent(new RemoteViews(context.getPackageName(), R.layout.layout_notification));//        } else {//            builder.setContent(new RemoteViews(context.getPackageName(), R.layout.layout_notification));//        }        builder.setContentIntent(pendingIntent)//设置通知栏点击意图                .setContentTitle(content)                .setTicker(content)                .setWhen(System.currentTimeMillis())//通知产生的时间，会在通知信息里显示，一般是系统获取到的时间                  .setAutoCancel(true)//设置这个标志当用户单击面板就可以让通知将自动取消                    .setOngoing(false)//ture，设置他为一个正在进行的通知。他们通常是用来表示一个后台任务,用户积极参与(如播放音乐)或以某种方式正在等待,因此占用设备(如一个文件下载,同步操作,主动网络连接)                  .setDefaults(Notification.DEFAULT_ALL)//向通知添加声音、闪灯和振动效果的最简单、最一致的方式是使用当前的用户默认设置，使用defaults属性，可以组合                  .setSmallIcon(R.mipmap.ic_launcher);//设置通知小ICON          Notification notification = builder.getNotification();        notificationManager.notify(i++, notification);    }}

重要的两点:
PendingIntent.getBroadcast(MyApplication.getInstance(), id++, intent, PendingIntent.FLAG_UPDATE_CURRENT);
PendingIntent.getBroadcast的第四个参数设置于PendingIntent.FLAG_UPDATE_CURRENT
第二个参数区分注册的Intent

2.NotificationClickReceiver 类

public class NotificationClickReceiver extends BroadcastReceiver {    private static final String TAG = "NotificationClickReceiver";    public static final String TYPE = "type";     @Override    public void onReceive(Context context, Intent intent) {        //todo 跳转之前要处理的逻辑        String action = intent.getAction();        int type = intent.getIntExtra(TYPE, -1);        if (type != -1) {            NotificationManager notificationManager = (NotificationManager) context.getSystemService(Context.NOTIFICATION_SERVICE);            notificationManager.cancel(type);        }        MilierLog.i(TAG,"action is :"+action);        if (action.equals("notification_clicked")) {            //处理点击事件            MilierLog.i(TAG,"NotificationClickReceiver***");//            Intent newIntent = new Intent(context,    MainActivity.class).addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);//            context.startActivity(newIntent);            RxBus.getDefault().post(Constants.NOTIFICATION);        }        if (action.equals("notification_cancelled")) {            //处理滑动清除和点击删除事件        }    }}

1. AndroidManifest.xml中注册监听

<receiver android:name=".broadcast.NotificationClickReceiver">            <intent-filter>                <action android:name="notification_cancelled"/>                <action android:name="notification_clicked"/>            </intent-filter>        </receiver>
