I have used with success inside an activity with TextView onclick ...

        //inside the doInBackground() ...

        try {
        while (true) {
        System.out.println(new Date());

        //should be 1 * 1000 for second
        Thread.sleep(5 * 1000);
        if (isCancelled()) {
              return null;
        }
          }

        } catch (InterruptedException e) {

        }

and in my onCreate() ...

     //set Activity
     final SplashActivity sPlashScreen = this;

     //init my Async Task
     final RetrieveFeedTask syncDo = new RetrieveFeedTask();
     syncDo.execute();

     //init skip link
     skip_text = (TextView) findViewById(R.id.skip_text);
     skip_text.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            //cancel Async
            syncDo.cancel(true);

            //goto/start another activity
            Intent intent = new Intent();
            intent.setClass(sPlashScreen, MainActivity.class);
            startActivity(intent);
            finish();

        }
    });

and my xml TextView element ...
