你需要檢查EDITTEXT對焦並設置AnimatioValue

edt.setOnFocusChangeListener(new View.OnFocusChangeListener() { 
      @Override 
      public void onFocusChange(View arg0, boolean hasfocus) { 
       if (hasfocus) { 
        Log.e("TAG", "edt focused"); 
        //ValueAnimator total 
        ValueAnimator valueAnimator = ValueAnimator.ofFloat(1f, 1.5f); 
        valueAnimator.setDuration(325); 
        valueAnimator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() { 
         public void onAnimationUpdate(ValueAnimator animation) { 
          float value = (Float) animation.getAnimatedValue(); 
          edt.setScaleX(value); 
          edt.setScaleY(value); 
          edt.requestLayout(); 
         } 
        }); 
        valueAnimator.start(); 
       } else { 
        Log.e("TAG", "edt not focused"); 
        //animation inverse 
       } 
      } 
});
