如何实现Thread与AsyncTask之间的通信

Question

I am developing an application using Android SDK. In this application I am facing a problem when an Activity starts a Thread . The new Thread starts an AsyncTask , but the Thread has to wait for completion of the AsyncTask execution.

Is it possible to start AsyncTask in a thread, and if so, how should it be implement? Please can anyone share your experience with me about this kind of tasks.

Thanks in advance

Answer 1

1. You should not create an AsyncTask from a thread other than main thread.
2. If you should wait anyway, why create AsyncTask? perform it on the thread.

Answer 2

just say thread to sleep for some times and then check a variable again like this in below code someValue was setted in asynctask postExecute method

new Thread(new Runnable(){
    @Override
    public void run(){
        while(!someValue) {
            try {
                Thread.sleep(200);
            } catch {
                Log.i("LOG", "ERROR");
            }
        }
        Log.i("LOG", "Async Task Finished");
    }
}).start();
