Question

In my app, I’ve been asked to add an auto update function. What I’m trying to do is have a timer event so that if the user hasn’t pressed the update button in the last 60 seconds, do a ‘refreshButton.performClick();’.

I’ve been searching but I can’t find an example where the timer interacts with the UI. I keep getting errors like ‘only the original thread that created a view hierarchy’.

If the user does press the button, I want to reset the timer.

Is this even possible?

Answer 1

You only can interact with aView from the UI thread.

You can make something like this in your timer task;

• Define this variable in your class:

  Handler handler = new Handler();

• In your timer task call:

    handler.post(new Runnable(){ 
         public void run(){  
             refreshButton.performClick();  
         }
    });
