Usage

From source file:com.hamzahrmalik.calculator2.Calculator.java

@Override
public void onTextSizeChanged(final TextView textView, float oldSize) {

        // Only animate text changes that occur from user input.
        return;/*from w w  w . j  a v a 2s. co m*/
    }

    // Calculate the values needed to perform the scale and translation
    // animations,
    // maintaining the same apparent baseline for the displayed text.
    final float textScale = oldSize / textView.getTextSize();
    final float translationX = (1.0f - textScale) * (textView.getWidth() / 2.0f - textView.getPaddingEnd());
    final float translationY = (1.0f - textScale) * (textView.getHeight() / 2.0f - textView.getPaddingBottom());

    final AnimatorSet animatorSet = new AnimatorSet();
