另一个 AsyncTask 中的 Android AsyncTask

Question

我想用这段代码在另一个 AsyncTask 中运行一个 AsyncTask：

   protected Integer doInBackground(Void... params) {
    InetAddress inetAddress;
    try {
        while (true) {
            inetAddress = InetAddress.getByName("192.168.1.1");
            mSocket = new Socket(inetAddress, 4444);

            SocketData data = new SocketData();


            GetPacket pack = new GetPacket();
            AsyncTask<SocketData, Integer, Integer> running = pack.execute(data);

但有一个错误： 方法必须从主线程调用android当前推断线程是worker

Answer 1

做在onProgressUpdate这个方法在MainThread上运行

protected Integer doInBackground(Void... params) {
    publishProgress(data);
}

protected void onProgressUpdate(SocketData... data) {
    GetPacket pack = new GetPacket();
    AsyncTask<SocketData, Integer, Integer> running = pack.execute(data[0]);
}
