Radio broadcast

Customize a broadcast inheritor within service

class FloatWindowBroadcastReceiver extends BroadcastReceiver {

        @Override
        public void onReceive(Context context, Intent intent) {
            String action = intent.getAction();
            //IntentFilter identity
            if (ACTION_FLOAT.equals(action)){
                //Transmit data
                String command = intent.getStringExtra("command");
                int position = intent.getIntExtra("position",0);
                switch (command){
                    case test:
                         break;
                    default:
                        ToastUtil.showMessage("Parameter error");
                        break;
                }

            }
        }
    }

Initialize, add identity, register broadcast.

private FloatWindowBroadcastReceiver floatWindowBroadcastReceiver;
@Override
    public void onCreate() {
        super.onCreate();
       //Initialization
        floatWindowBroadcastReceiver = new FloatWindowBroadcastReceiver();
       //Identification
        IntentFilter filter = new IntentFilter(ACTION_FLOAT);
       //Registered broadcasting
        registerReceiver(floatWindowBroadcastReceiver,filter);       
    }

Unregister broadcast when service is destroyed

@Override
    public void onDestroy() {
        if (floatWindowBroadcastReceiver != null){
            unregisterReceiver(floatWindowBroadcastReceiver);
            floatWindowBroadcastReceiver = null;
        }
        super.onDestroy();
    }

Call the method action in another page

Intent intent=new Intent(FloatWindowService.ACTION_FLOAT);
intent.putExtra("command","add");
sendBroadcast(intent);

Handler

Create a Handler in service to receive messages

private Handler handler=new Handler(){
        @Override
        public void handleMessage(Message msg) {
            super.handleMessage(msg);
            switch (msg.what){

            }
        }
 };

Send message, whether it is necessary to enable thread to operate according to requirements

 public void send(){
     new Thread(new Runnable() {
          @Override
          public void run() {
          Message message=new Message();
          Bundle bundle=new Bundle();
          message.setData(bundle);
          handler.sendMessageDelayed(message,2000);
    }).start();

 }
