不断将数据传递给AsyncTask吗？

Question

In my Android app, I have a snippet of code, similar to Run code for x seconds in Java?

long t= System.currentTimeMillis();
long end = t+15000;
while(System.currentTimeMillis() < end) {
//useful calculation
}

And this code will freeze the UI thread, so I'm wondering if there's a way to continuously pass in data to my AsyncTask that will do the calculation in the background thread to avoid freezing? Or is there a better way, or to keep calling AsyncTask from within my while loop?

For this purpose, use a Handler instead.

It goes like this :

Handler timerHandler = new Handler();

Runnable timerRunnable = new Runnable() {

    @Override
    public void run() {
        //READ HERE WHAT YOU NEED FROM THE SENSOR (useful calculation)

        //And then set the next execution of the sensor reading
        timerHandler.postDelayed(this, 1000); //runs 1000 milliseconds
    }
};

//Launch It for the first time
timerHandler.post(timerRunnable);

//Whenever you would like to stop it, use the following commented line
//timerHandler.removeCallbacks(timerRunnable);
