I have a TextView showing integer value. Integer value is transferred from previous activity, and I want to add nice animation. I want to if for example int value is 73, I want textView to increase shown number by 1 until 73, so it would be 1-2-3-4-5...etc etc. How can I do this?

推荐答案

下面是一个简单的功能，根据最初和最终值动画一个TextView的文本

Here is a simple function to animate the text of a textView according to an initial and final value

public void animateTextView(int initialValue, int finalValue, final TextView textview) {
        DecelerateInterpolator decelerateInterpolator = new DecelerateInterpolator(0.8f);
        int start = Math.min(initialValue, finalValue);
        int end = Math.max(initialValue, finalValue);
        int difference = Math.abs(finalValue - initialValue);
        Handler handler = new Handler();
        for (int count = start; count <= end; count++) {
            int time = Math.round(decelerateInterpolator.getInterpolation((((float) count) / difference)) * 100) * count;
            final int finalCount = ((initialValue > finalValue) ? initialValue - count : count);
            handler.postDelayed(new Runnable() {
                @Override
                public void run() {
                    textview.setText(finalCount + "");
                }
            }, time);
        }
    }
