Answer 1

I replaced timers with Runnables/Handlers recently, it’s much easier

//declare at top of your activity
private Handler h = new Handler();

private Runnable myRunnable = new Runnable() {
   public void run() {
    //do stuff  

        //run again in one second
    h.postDelayed(myRunnable, 1000);
   }
};

//trigger the runnable somewhere in your code e.g. onClickHander or onCreate etc
h.postDelayed(myRunnable, 1000);
