Android 代码实现动画

//透明动画

AlphaAnimationalphaAnimation =new AlphaAnimation(1.0f,0.0f);

alphaAnimation.setDuration(3000);

alphaAnimation.setFillAfter(true);

iv.startAnimation(alphaAnimation);

//渐变动画

ScaleAnimation scaleAnimation =new ScaleAnimation(0,1,0,1);

scaleAnimation.setDuration(3000);

scaleAnimation.setFillAfter(true);

iv.startAnimation(scaleAnimation);

//平移动画

TranslateAnimation translateAnimation =new TranslateAnimation(0,300,0,300);

translateAnimation.setDuration(3000);

translateAnimation.setFillAfter(true);

iv.startAnimation(translateAnimation);

//旋转动画

RotateAnimation rotateAnimation =new RotateAnimation(0f,360f, Animation.RELATIVE_TO_SELF,0.5f, Animation.RELATIVE_TO_SELF,0.5f);

rotateAnimation.setDuration(3000);

rotateAnimation.setFillAfter(true);

iv.startAnimation(rotateAnimation);
