Android 8.0及以上广播（动态、静态）使用

基本使用

  createNotificationChannel("@AA","@我的消息",NotificationManager.IMPORTANCE_HIGH);
    ButtonHandeler bh = new ButtonHandeler();
    setOnClickListerner(this);

    private String createNotificationChannel(String channelId,String channelName,int level){
        if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.O){
            NotificationManager manager = (NotificationManager)getSystemService(NOTIFCATION_SERVICE);
            NotificationChannel channel = new NotificationChannel(channelId,channelName,level);
            channel.setDescription("通知级别"+level);
            channel.setSound(Uri.parse("播放音乐地址"),Notification.AUDIO_ATTRIBUTES_DEFAULT);
            manager.createNotificationChannel(channel);
        }
    }

    private class ButtonHandeler implements View.OnClickListener{

        @Override
        public void onClick(View view) {
            NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
            Intent intent = new Intent(MainActivity.this, PayActivity.class):
            PendingIntent pendingIntent = PendingIntent.getActivity(
                    MainActivity.this,
                    0,
                    intent,
                    PendingIntent.FLAG_MUTABLE);
            Notification notification = new NotificationCompat.Builder(MainActivity.this, channelId)
                    .setContentInfo("你有新消息")
                    .setContentText("你的花费已用完，请及时充值")
                    .setContentIntent(pendingIntent)
                    .setWhen(System.currentTimeMillis())
                    .setSmallIcon(R.drawable.bb_small_3)
                    .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.bb))
                    .setAutoCancel(true)
                    .setDefaults(Notification.DEFAULT_ALL).build();
            manager.notify(1, notification):
        }

    }

完整的广播发送接受示例

//定义广播
 public class MessageBroadcastReceiver extends BroadcastReceiver {
        @Override
        public void onReceive(Context context, Intent intent) {
            if (intent == null) return;
            if (! TextUtils.equals(intent.getAction(), ACTION_TEST)) {
                return;
            }
            final String param = intent.getStringExtra("param");
            Log.i("TAG", " 广播里面收到参数：" + param);//接受广播
            runOnUiThread(new Runnable() {
                @Override
                public void run() {

                }
            });
        }
    }
  //注册广播
  private void registerBroadCast() {
        try {
            //注册点击事件广播
            IntentFilter filter = new IntentFilter(ACTION_TEST);
            filter.setPriority(Integer.MAX_VALUE); //设置级别
            MessageBroadcastReceiver broadcastReceiver = new MessageBroadcastReceiver();
            LocalBroadcastManager.getInstance(this).registerReceiver(broadcastReceiver, filter);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
  //发送广播
     try {
            Intent intent = new Intent();
            intent.putExtra("param", param);
            intent.setAction(ACTION_TEST);
            LocalBroadcastManager.getInstance(this).sendBroadcast(intent);//发送标准广播
        } catch (Exception e) {
            e.printStackTrace();
        }

动态广播基本使用

    private TimeChangeReceiver timeChangeReceiver;

    public void show() {
        IntentFilter intentFilter = new IntentFilter();
        intentFilter.addAction("android.intent.action.TIME_TICK");
        registerReceiver(timeChangeReceiver,intentFilter);
    }

    private class TimeChangeReceiver extends BroadcastReceiver{
        @Override
        public void onReceive(Context context, Intent intent) {
            Date date = new Date();
            //这里设置通知显示的内容
        }
    }

    protected  void  onDestroy(){
        super.onDestroy();
        unregisterReceiver(timeChangeReceiver);
    }

静态广播基本使用

//创建广播文件
//清单文件中注册
<receiver>
android:name="MyReceiver
android:enabled="true'
android:exported="true"
<intent-filter>
<action android:name="com.example.noticicationtest.CLOSE_NOTIFICATION"/></intent-filter>
</receiver>
//

    private class  MyReceiver extends BroadcastReceiver{
        @Override
        public void onReceive(Context context, Intent intent) {
            NotificationManager manager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
            manager.cancel(intent.getIntExtra("nid",888));
        }
    }

//
    NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
            Intent intent = new Intent(MainActivity.this, PayActivity.class):
            PendingIntent pendingIntent = PendingIntent.getActivity(
                    MainActivity.this,
                    0,
                    intent,
                    PendingIntent.FLAG_MUTABLE);
                        Intent intent2 = new Intent("com.example.noticicationtest.CLOSE_NOTIFICATION");
    intent2.setPackage(getPackageName);//
    intent2.putExtra("nid",id);
    PendingIntent pendingIntent = PendingIntent.getActivity(
            MainActivity.this,
            id,
            intent,
            PendingIntent.FLAG_MUTABLE|PendingIntent.FLAG_UPDATE_CURRENT);
            Notification notification = new NotificationCompat.Builder(MainActivity.this, channelId)
                    .setContentInfo("你有新消息")
                    .setContentText("你的花费已用完，请及时充值")
                    .setContentIntent(pendingIntent)
                    .setWhen(System.currentTimeMillis())
                    .setSmallIcon(R.drawable.bb_small_3)
                    .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.drawable.bb))
                    .setAutoCancel(true)
                        .addAction(0,"关闭通知"，intent2);
                    .setDefaults(Notification.DEFAULT_ALL).build();
            manager.notify(id++, notification):
