How to create a count-up effect for a textView in Android

I've used a more conventional Android-style animation for this:

        ValueAnimator animator = new ValueAnimator();
        animator.setObjectValues(0, count);
        animator.addUpdateListener(new AnimatorUpdateListener() {
            public void onAnimationUpdate(ValueAnimator animation) {
                view.setText(String.valueOf(animation.getAnimatedValue()));
            }
        });
        animator.setEvaluator(new TypeEvaluator<Integer>() {
            public Integer evaluate(float fraction, Integer startValue, Integer endValue) {
                return Math.round(startValue + (endValue - startValue) * fraction);
            }
        });
        animator.setDuration(1000);
        animator.start();

You can play with the 0 and count values to make the counter go from any number to any number, and play with the 1000 to set the duration of the entire animation.

Note that this supports Android API level 11 and above, but you can use the awesome nineoldandroids project to make it backward compatible easily.

Try this:

private int counter = 0;
private int total = 30; // the total number
//...
//when you want to start the counting start the thread bellow.
    new Thread(new Runnable() {

                public void run() {
                    while (counter < total) {
                        try {
                            Thread.sleep(500);
                        } catch (InterruptedException e) {
                            // TODO Auto-generated catch block
                            e.printStackTrace();
                        }
                        t.post(new Runnable() {

                            public void run() {
                                t.setText("" + counter);

                            }

                        });
                        counter++;
                    }

                }

            }).start();
