Android-将数据从活动发送到服务

您可以在服务中创建一个BroadcastReceiver对象,并将其注册以侦听所需的任何广播事件。是这样的:

BroadcastReceiver mScreenStateReceiver = new BroadcastReceiver() {

    @Override
    public void onReceive(Context context, Intent intent) {
        //handle the broadcast event here
    }
};

@Override
public void onCreate() {
    super.onCreate();

    IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_OFF);
    filter.addAction(Intent.ACTION_SCREEN_ON);
    registerReceiver(mScreenStateReceiver, filter);

}

@Override
public void onDestroy() {
    super.onDestroy();
    unregisterReceiver(mScreenStateReceiver);
}

当做,
