Android  简单的动画效果有Animtion 类提供 1.在XML中实现动画效果；2.在java代码中实现动画效果。

动画相关的属性

1.@android:anim/accelerate_decelerate_interpolator：先加速后减速

2.@android:anim/accelerate_interpolator ：加速

3.@android:anim/decelerate_interpolator：减速

4.@android:anim/anticipate_interpolator：先往动画移动的反方向移动一点然后在沿着设定的动画移动  移动轨迹如下图。

5.anticipate_overshoot_interpolator：先往动画的反方向移动一点，然后沿着设定的方向移动到终点之后继续移动一点然后在回弹到最终设定的位置。如下图：

6.@android:anim/bounce_interpolator：动画移动到最后会有几次回弹的效果，最终停止在设定的位置。

7.@android:anim/cycle_interpolator：动画周期移动。

8.@android:anim/linear_interpolator：动画匀速移动。

9.@android:anim/overshoot_interpolator：动画到最后的位置会向反方向移动一点。

一..XML 实现 alpha ：

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" 
   >
	
    <alpha
        android:duration="2000"
        android:fromAlpha="0"
        android:repeatCount="3"//动画重复的次数
        android:repeatMode="reverse"//动画重复的模式  reverse：倒序，即从最后一帧播放动画；  restart：顺序，即从头开始播放动画
        android:toAlpha="1.0" />

</set>

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android" 
   android:fillAfter="true"
   >
	
    <alpha
        android:duration="2000"
        android:fromAlpha="0"
        
        android:repeatCount="3"
        android:repeatMode="reverse"
        android:toAlpha="1.0" />

</set>

二.代码实现alpha  

Animation anim = new AlphaAnimation(0f, 1.0f);
		anim.setDuration(2000);
		anim.setRepeatCount(Animation.INFINITE);
		anim.setRepeatMode(Animation.RESTART);

三.XML实现scale

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:fillAfter="true"
    android:interpolator="@android:anim/decelerate_interpolator" >
 <!-- 画面停留在最后一帧 -->
    >

    <scale
        android:duration="2000"
        android:fromXScale="0.5"
        android:fromYScale="0.5"
        android:pivotX="50.0%" >
 <!-- 动画相对于空间X坐标开始的位置50。0%表示从空间的正中央开始缩放动画 -->
        android:pivotY="50.0%"
        android:repeatCount="3"
        android:repeatMode="reverse"
        android:toXScale="1.0"
        android:toYScale="1.0"
         />

    </scale>

</set>

Animation anim1 = new ScaleAnimation(0.5f, 1.0f, 0.5f, 1.0f, 0.5f, 0.5f);
		anim1.setDuration(2000);
		anim1.setRepeatCount(3);
		anim1.setRepeatMode(Animation.REVERSE);
		anim1.setInterpolator(this, interpolator.accelerate_decelerate);
		anim1.setFillAfter(true);

五.XML实现stranslate  

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:interpolator="@android:anim/decelerate_interpolator"
    android:fillAfter="true" >

    <translate
        android:duration="2000"
        android:fromXDelta="0"
        android:fromYDelta="0"
        android:toXDelta="0"
        android:toYDelta="1080" />

</set>

Animation animTranlate = new TranslateAnimation(0, 0, 0, 400);
		animTranlate.setDuration(2000);
		animTranlate.setFillAfter(true);
		animTranlate.setInterpolator(this, interpolator.bounce);
		text.startAnimation(animTranlate);

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:fillAfter="true"
    android:interpolator="@android:anim/accelerate_decelerate_interpolator" >

    <rotate
        android:duration="2000"
        android:fromDegrees="0"
        android:pivotX="50%"
        android:pivotY="50%"
        android:toDegrees="180" //负数就是逆时针，正数顺时针。

/>

</set>

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

		animRotate.setDuration(2000);
		animRotate.setInterpolator(this, interpolator.bounce);
		animRotate.setFillAfter(true);
<span style="white-space:pre">		animRotate.setStartOffset(2000);</span>//动画执行前停留时间
		text.startAnimation(animRotate);

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="2000"
    android:fillAfter="true"
    android:interpolator="@android:anim/accelerate_decelerate_interpolator" >

    <alpha
        android:fromAlpha="0"
        android:toAlpha="1.0" />

    <scale
        android:fromXScale="0"
        android:fromYScale="0"
        android:pivotX="50%"
        android:pivotY="50%"
        android:toXScale="1.0"
        android:toYScale="1.0" />

</set>

Animation anim1 = new ScaleAnimation(0.5f, 1.0f, 0.5f, 1.0f, 0.5f, 0.5f);
		anim1.setDuration(2000);
		anim1.setRepeatCount(3);
		anim1.setRepeatMode(Animation.REVERSE);
		anim1.setInterpolator(this, interpolator.accelerate_decelerate);
		anim1.setFillAfter(true);
		// text.setAnimation(anim1);

		Animation animTranlate = new TranslateAnimation(0, 0, 0, 400);
		animTranlate.setDuration(2000);
		animTranlate.setFillAfter(true);
		animTranlate.setInterpolator(this, interpolator.bounce);
		// text.startAnimation(animTranlate);
		Animation animRotate = new RotateAnimation(0f, 360f,
				Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF,
				0.5f);

		animRotate.setDuration(2000);
		animRotate.setInterpolator(this, interpolator.bounce);
		animRotate.setFillAfter(true);
		// text.startAnimation(animRotate);

		AnimationSet animationSet = new AnimationSet(true);
		animationSet.addAnimation(animRotate);
		animationSet.addAnimation(animTranlate);
		animationSet.addAnimation(anim1);
		text.startAnimation(animationSet);
