如何讓動畫視圖消失？

使用NineOldAndroid的AnimatorSet，當我想擺脫的動畫，使消失的觀點 - 什麼也沒有發生

如何使視圖消失？

public void showAnimation(boolean show) { 
    if (show) { 
     if (mTarget.getVisibility() != View.VISIBLE) { 
      // play sound 

      mTarget.setVisibility(View.VISIBLE); 
      pauseAnimation = false; 
      // start animation 
      initTargetAnimation(); 
     } 
    } else { 

     pauseAnimation = true; //All of this block gets executed in the debugger, but none of it actually take effect 
     if (mTarget.getAnimation() != null) { 
      mTarget.getAnimation().cancel(); 
      mTarget.clearAnimation(); 
     } 
     mTarget.setVisibility(View.GONE); 
    } 



} 

    private void initTargetAnimation() { 

    final AnimatorSet set = new AnimatorSet(); 

    // init animation properties 
    set.playTogether(ObjectAnimator.ofFloat(mTarget, "scaleX", RELEVANT_ANIMATION_SEQUENCE), ObjectAnimator.ofFloat(mTarget, "scaleY", RELEVANT_ANIMATION_SEQUENCE)); 

    // add animation listener 
    set.setDuration(1500).addListener(new Animator.AnimatorListener() { 
     @Override 
     public void onAnimationStart(Animator animation) { 

     } 

     @Override 
     public void onAnimationEnd(Animator animation) { 
      // RESTART ANIMATION 
      if (!pauseAnimation) { 
       initTargetAnimation(); // TODO fix 
      } 
     } 

     @Override 
     public void onAnimationCancel(Animator animation) { 

     } 

     @Override 
     public void onAnimationRepeat(Animator animation) { 

     } 
    }); 

    // start animation 
    set.start(); 

}

當您在View mTarget上設置可見性後，嘗試在其上調用invalidate（）。這假定你從主線程調用它，否則它是postinvalidate（）。
