Android 技术总结(018)—— ImageView动画出现锯齿问题

/**

* 生成缩放的动画

*/

private AnimationSet makeAnimation() {

// 创建复合动画

AnimationSet animationSet = new AnimationSet(true);

// 创建ScaleAnimation对象

ScaleAnimation scaleAnimation = new ScaleAnimation(1, 0.1f, 1, 0.1f,

Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF,

0.5f);

scaleAnimation.setDuration(800);

animationSet.addAnimation(scaleAnimation);

// 创建TranslateAnimation对象

TranslateAnimation translateAnimation = new TranslateAnimation(

Animation.ABSOLUTE, 0f, Animation.ABSOLUTE,

(float) -(mScreenWidth * 0.14), Animation.ABSOLUTE, 0f,

Animation.ABSOLUTE, (float) (mScreenHeight / 1.56));

translateAnimation.setDuration(800);

animationSet.addAnimation(translateAnimation);

// 设置插值器

animationSet.setInterpolator(new AccelerateInterpolator());

return animationSet;

}// 初始化动画

mShrinkAnimation = makeAnimation();// 开启动画

mCutImage.setAnimation(mShrinkAnimation);

mShrinkAnimation.start();

mShrinkAnimation.setAnimationListener(mShrinkAnimationListener);解决办法：给ImageView设置padding值。
