属性动画相关使用

  1.使用propertyValuesHolder，属性动画多组属性同时改变

[java]  view plain copy

1. public void propertyValuesHolder(View view)  
2.     {  
3.         PropertyValuesHolder pvhX = PropertyValuesHolder.ofFloat("alpha", 1f,  
4.                 0f, 1f);  
5.         PropertyValuesHolder pvhY = PropertyValuesHolder.ofFloat("scaleX", 1f,  
6.                 0, 1f);  
7.         PropertyValuesHolder pvhZ = PropertyValuesHolder.ofFloat("scaleY", 1f,  
8.                 0, 1f);  
9.         ObjectAnimator.ofPropertyValuesHolder(view, pvhX, pvhY,pvhZ).setDuration(1000).start();  
10.     }  
11. 
    
    
    
    
    
    2.viewhelper的使用，setbackground和alpha,还有等等的属性能在2.x一下机子运行
    
    
      ViewHelper.setScaleX(view,1f);

                 ViewHelper.setScaleY(view,1f);
