  1. private void flipCoin() {
  2.     final Drawable drawable = getResources().getDrawable(R.drawable.ic_launcher_background);
  3.     final ImageView iv = ((ImageView) findViewById(R.id.imageView));
  4.     iv.setRotationY(0f);
  5.     //iv.animate().setDuration(10);
  6.     iv.animate().rotationY(90f).setListener(new Animator.AnimatorListener() {
  8.         @Override
  9.         public void onAnimationStart(Animator animation) {
  10.         }
  12.         @Override

  14.         }
  16.         @Override
  17.         public void onAnimationEnd(Animator animation) {
  18.             iv.setImageDrawable(drawable);
  19.             iv.setRotationY(270f);

i have this code here. I want that the Imageview do the animation 5 times. How i need to set the setRepeatCount? How to inilize it?

  1. private void flipCoin() {
  2.     final Drawable drawable = getResources().getDrawable(R.drawable.ic_launcher_background);
  3.     final ImageView iv = ((ImageView) findViewById(R.id.imageView));
  4.     iv.setRotationY(0f);
  5.     //iv.animate().setDuration(10);
  6.     iv.animate().rotationY(90f).setListener(new Animator.AnimatorListener() {

  10.         }
  12.         @Override
  13.         public void onAnimationRepeat(Animator animation) {
  14.         }
  16.         @Override
  17.         public void onAnimationEnd(Animator animation) {
  18.             iv.setImageDrawable(drawable);
  19.             iv.setRotationY(270f);
  20.             iv.animate().rotationY(360f).setListener(null);
  22.         }
  24.         @Override

以下是您要翻译的内容：

方法setRepeatCount属于Animation类，您正在使用Animator。

尝试这样做：

  1. int times = 5;
  3. private void flipCoin() {
  4.     final Drawable drawable = getResources().getDrawable(R.drawable.ic_launcher_background);
  5.     final ImageView iv = findViewById(R.id.imageView);
  6.     iv.setRotationY(0f);
  7.     //iv.animate().setDuration(10);
  8.     final ViewPropertyAnimator viewPropertyAnimator = iv.animate();
  9.     viewPropertyAnimator.rotationY(90f);
  10.     viewPropertyAnimator.setListener(new Animator.AnimatorListener() {
  12.         @Override
  13.         public void onAnimationStart(Animator animation) {
  14.         }
  16.         @Override
  17.         public void onAnimationRepeat(Animator animation) {
  18.         }
  20.         @Override
  21.         public void onAnimationEnd(Animator animation) {
  23.             times--;
  24.             if (times > 0) {
  25.                 iv.setImageDrawable(drawable);
  26.                 iv.setRotationY(270f);
  27.                 viewPropertyAnimator.rotationY(360f);
  28.                 viewPropertyAnimator.start(); //重新开始
  29.             }
  30.         }
  32.         @Override
  33.         public void onAnimationCancel(Animator animation) {
  34.         }
  35.     });
  37.     viewPropertyAnimator.start(); //初始化
  38. }

英文:

The method setRepeatCount belongs to Animation class, you are using Animator.

Try this:

  1. int times = 5;
  3. private void flipCoin() {
  4.     final Drawable drawable = getResources().getDrawable(R.drawable.ic_launcher_background);
  5.     final ImageView iv = findViewById(R.id.imageView);
  6.     iv.setRotationY(0f);
  7.     //iv.animate().setDuration(10);
  8.     final ViewPropertyAnimator viewPropertyAnimator = iv.animate();
  9.     viewPropertyAnimator.rotationY(90f);
  10.     viewPropertyAnimator.setListener(new Animator.AnimatorListener() {
  12.         @Override
  13.         public void onAnimationStart(Animator animation) {
  14.         }
  16.         @Override
  17.         public void onAnimationRepeat(Animator animation) {
  18.         }
  20.         @Override
  21.         public void onAnimationEnd(Animator animation) {
  23.             times--;
  24.             if (times > 0) {
  25.                 iv.setImageDrawable(drawable);
  26.                 iv.setRotationY(270f);
  27.                 viewPropertyAnimator.rotationY(360f);
  28.                 viewPropertyAnimator.start(); //Restart
  29.             }
  30.         }
  32.         @Override
  33.         public void onAnimationCancel(Animator animation) {
  34.         }
  35.     });
  37.     viewPropertyAnimator.start(); //Init
  38. }
