图片放大

1、可以这样直接设置宽高缩放比例：image.setScaleX(); image.setScaleY();

2、用动画：ScaleAnimation

		Animation animation = new ScaleAnimation(1.0f, 3.0f, 1.0f, 3.0f,Animation.RELATIVE_TO_SELF,0.5f,Animation.RELATIVE_TO_SELF,0.5f);
		animation.setDuration(2000);
		animation.setFillAfter(true);//保持放大后的状态
		image.startAnimation(animation );
