代码:

  //透明度变化
                AlphaAnimation alphaAnimation = new AlphaAnimation(0.0f, 1.0f);//第一个参数开始的透明度,第二个参数结束的透明度
                alphaAnimation.setDuration(3000);//多长时间完成这个动作
                imageView1.startAnimation(alphaAnimation);

第二种方法:

1,先在Android列表下,在mode的res下建一个文件夹注意文件类型为anim 
2,在project列表下,找到上一步建的文件夹在里面建一个xml文件 
3,在里面写透明度,平移等的方法 
下面的代码里我只写了旋转跟缩放的

效果:
