Question

I do have a button and when this button is clicked I want to do some actions and revert them back, in lets to say 5 secs. Example, when Button A is clicked, TextA.Text becomes “Clicked” for 5 secs, in 5 secs the value of text should come back to its original. Here what I do have, but I feel that it is totally wrong way. The code that do delay:

diff=time2-time1;

            while (diff<5000) {
                //Log.d("Timer is", String.valueOf(diff));
                time2=System.currentTimeMillis();
                diff=time2-time1;
            }

so untill loop is working its simulate delay and after i do what i want. Any advice?

Answer 1

Use a Handler, something like this:

new Handler().postDelayed(new Runnable() {
    void run() {
        // do something later
    }
}, 5000);

Edit: Note that this solution allows the main thread to continue during the delay – refreshing the GUI, handling activity changes (such as “Home” button) correctly, etc. Using Thread.sleep() does not.
