帧动画+补间动画

帧动画+补间动画

帧动画得在drawable下创建一个xml文件
在aniation-list下添加item 两个属性 一个drawable放图片 duration是图片显示的时间

补间动画
分为透明 旋转 平移 缩放 还可以把他们组合起来

旋转

	<alpha xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="3000"
    android:fillBefore="true"
    android:fromAlpha="1.0"
    android:toAlpha="0.0">
</alpha>

     Animation animation = AnimationUtils.loadAnimation(MainActivity.this, R.anim.alpha);
        imageView.startAnimation(animation);

平移

	<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromXDelta="0"
    android:fromYDelta="0"
    android:toXDelta="200"
    android:toYDelta="300"
    android:duration="3000"
    android:fillBefore="true">

</translate>
Animation animation = AnimationUtils.loadAnimation(MainActivity.this, R.anim.translate);
        imageView.startAnimation(animation);

旋转

<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:fromDegrees="0"
    android:toDegrees="720"
    android:pivotX="200"
    android:pivotY="200"
    android:duration="3000"
    android:fillBefore="true">
Animation animation = AnimationUtils.loadAnimation(MainActivity.this, R.anim.rotate );
        imageView.startAnimation(animation);

缩放

 ScaleAnimation scaleAnimation = new ScaleAnimation(1, 2, 1, 4, ScaleAnimation.ABSOLUTE, 100, ScaleAnimation.ABSOLUTE, 100);
        scaleAnimation.setFillBefore(true);
        scaleAnimation.setDuration(3000);
//        scaleAnimation.setRepeatMode(ScaleAnimation.REVERSE);
//        scaleAnimation.setInterpolator(new BounceInterpolator());

        imageView.startAnimation(scaleAnimation);
