Android Fragment onCreateAnimator总是输入true

Question

我在htc欲望4.0.3上面临这个问题。即使片段正在退出，动画仍会一直输入...... 4.4或5.0上不存在问题

 public Animator onCreateAnimator(int transit, boolean enter, int nextAnim) {
    Animator anim;
    if (enter) {
          Log.d("Animation", "enter");
        anim = ENTER_RIGHT_ANIMATOR;
    } else {
         Log.d("Animation", "exit");
       anim = EXIT_RIGHT_ANIMATOR;
   }
    return anim;

}
