1、帶數字的進度條 NumberProgressView
先來效果圖
添加動畫方法: private void setTvAnimation(final TextView view, final int mProgressBar) {
ValueAnimator animator = ValueAnimator.ofInt(0, mProgressBar).setDuration(5000);
animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
@Override
public void onAnimationUpdate(ValueAnimator valueAnimator) {
view.setText(String.valueOf(valueAnimator.getAnimatedValue()));
}
});
animator.start();
}
使用方法:直接把控件傳進去就可以了
/開啓動畫
setAnimation(HProgress,2000);
