Question

I have a button that I don’t want to be clickable until a certain amount of time has run (say, 5 seconds?) I tried creating a thread like this

    continueButtonThread =  new Thread()
    {
        @Override
        public void run()
        {
            try {
                synchronized(this){
                    wait(5000);
                }
            }
            catch(InterruptedException ex){                    
            }

            continueButton.setVisibility(0);                
        }
    };

    continueButtonThread.start();

But I can’t modify the setVisibility property of the button within a different thread. This is the error from the LogCat:

10-02 14:35:05.908: ERROR/AndroidRuntime(14400): android.view.ViewRoot$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views.

Any other way to get around this?

Answer 1

The problem is that you can touch views of your activity only in UI thread. you can do it by using runOnUiThread function. I would like to suggest you to use

handler.postDelayed(runnable, 5000)`
