Question

I have an activity thats waiting for the user press on an image. if the user dont press anything in 3 second i want the activity to close (finish()).
thats my code:

private final int delay = 3000;
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.after_hangup);
    getWindow().addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED);
    final ImageView pressToLaunchbrowser = (ImageView) findViewById(R.id.after_hang_up_image);

    pressToLaunchbrowser.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            //getWindow().addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);   // if we want to open the device.
            Intent intent = new Intent(Intent.ACTION_VIEW);
            intent.setData(Uri.parse(url));
            startActivity(intent);
            Thread.interrupted();
        }
    }); 
    new Thread() {
        public void run() {
            try {
                    Thread.sleep(delay);
                    finish();
            }
            catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }.start();
}}

My question is how can i wake the Thread if the press was made? i tried Thread.interrupted(); but its not working. the thread still waits 3 seconds if i press or not. Thanks!
