Timer timer = new Timer(); 
timer.scheduleAtFixedRate(new TimerTask() 
    { 
            


        

Answer 1

Use onPostDelayed() accessed from any of your View or a Handler. You save memory by not creating a Timer or new Thread.

private final Handler mHandler = new Handler();

private final Runnable mUpdateUI = new Runnable() {
    public void run() {
        displayData();
        mHandler.postDelayed(mUpdateUI, 1000); // 1 second
        }
    }
};

mHandler.post(mUpdateUI);
