安卓：执行线程与onTouchListener循环（） [英] Android: executing the thread in a loop with onTouchListener()

问题描述

你好我的应用程序有8个按键。每个按钮配置onclickListener（）被点击的字符串写入TI插座时。现在我想，当我preSS并按住该按钮的字符串必须写在一个循环。这就是我要做的。

Hi in my app there are 8 buttons. Each button is configured onclickListener() when it is clicked the String is written ti the socket. Now i want that when i press and hold the button the String must be written in a loop. Here is what i am trying to do.

bLeft.setOnTouchListener(new View.OnTouchListener() {

        @Override
        public boolean onTouch(View arg0, MotionEvent event) {
            // TODO Auto-generated method stub
            MyThread start = new MyThread();
             boolean isReleased = event.getAction() == MotionEvent.ACTION_UP || event.getAction() == MotionEvent.ACTION_CANCEL;
             boolean isPressed = event.getAction() == MotionEvent.ACTION_DOWN;

        while (isPressed) {

                start.execute(ip, "left");

                break;
        }
            return false;
        }
    });

不知何故，我不知道为什么它不工作。开始，执行（字符串，字符串）执行中的AsyncTask类线程创建一个socket输出流。

Somehow i don't know why it is not working. start,execute(string, string) executes the thread in AsyncTask class to create a socket and output stream.

推荐答案

这是asynchronos任务只能执行一次......你试图使用它在一个while循环......这意味着你试图重复使用它。 ..你需要重新初始化启动的，而每次循环......

an asynchronos task can only execute one time... you are trying to employ it in a while loop... meaning you are trying to use it repeatedly... you need to re-initialize start for each iteration of the while loop...

 while (ispressed){
      start = new YourAsyncTask();
      start.execute(params);
 }
