1.为一个activity定义进入和退出的动画：
首先在Manifest文件中为activity 添加style属性
<activity
android:name=".activity.MainTopRightDialog"
android:theme="@style/MyDialogStyleTop" />
<activity
然后在styles.xml文件中定义MyDialogStyleTop属性，以及里边引用的相关属性当然还要在anim文件夹下编写push_top_in2等动画文件：
<style name="AnimTop2" parent="@android:style/Animation">
<item name="android:windowEnterAnimation">@anim/push_top_in2</item>
<item name="android:windowExitAnimation">@anim/push_top_out2</item>
</style>
<style name="MyDialogStyleTop" parent="android:Theme.Dialog" >
<item name="android:windowAnimationStyle">@style/AnimTop2</item>
<item name="android:windowFrame">@null</item><!--边框-->
<item name="android:windowIsFloating">true</item><!--是否浮现在activity之上-->
<item name="android:windowIsTranslucent">true</item><!--半透明-->
<item name="android:windowNoTitle">true</item><!--无标题-->
<item name="android:windowBackground">@android:color/transparent</item><!--背景透明-->
<item name="android:backgroundDimEnabled">false</item><!--模糊-->
</style>
下面是animpush_top_in2.xml
<?xml version="1.0" encoding="utf-8"?>
<!-- 上下滑入式 -->
<scale xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="@android:anim/accelerate_decelerate_interpolator"
android:fromXScale="1.0"
android:toXScale="1.0"
android:fromYScale="0"
android:toYScale="1.0"
android:pivotX="0"
android:pivotY="80%"
android:duration="800" />
2.
对于点击之后触发事件而进行的动画可以用先编写动画文件，再加载，然后用相应的view启动
Animation anim=AnimationUtils.loadAnimation(this,R.anim.my_rotate_action); findViewById(R.id.TextView01).startAnimation(anim);或者像下面这样：
public void startAnim () { //定义摇一摇动画动画
AnimationSet animup = new AnimationSet(true);
TranslateAnimation mytranslateanimup0 = new TranslateAnimation(Animation.RELATIVE_TO_SELF,0f,Animation.RELATIVE_TO_SELF,0f,Animation.RELATIVE_TO_SELF,0f,Animation.RELATIVE_TO_SELF,-0.5f);
mytranslateanimup0.setDuration(1000);
TranslateAnimation mytranslateanimup1 = new TranslateAnimation(Animation.RELATIVE_TO_SELF,0f,Animation.RELATIVE_TO_SELF,0f,Animation.RELATIVE_TO_SELF,0f,Animation.RELATIVE_TO_SELF,+0.5f);
mytranslateanimup1.setDuration(1000);
mytranslateanimup1.setStartOffset(1000);
animup.addAnimation(mytranslateanimup0);
animup.addAnimation(mytranslateanimup1);
mImgUp.startAnimation(animup);
AnimationSet animdn = new AnimationSet(true);
TranslateAnimation mytranslateanimdn0 = new TranslateAnimation(Animation.RELATIVE_TO_SELF,0f,Animation.RELATIVE_TO_SELF,0f,Animation.RELATIVE_TO_SELF,0f,Animation.RELATIVE_TO_SELF,+0.5f);
mytranslateanimdn0.setDuration(1000);
TranslateAnimation mytranslateanimdn1 = new TranslateAnimation(Animation.RELATIVE_TO_SELF,0f,Animation.RELATIVE_TO_SELF,0f,Animation.RELATIVE_TO_SELF,0f,Animation.RELATIVE_TO_SELF,-0.5f);
mytranslateanimdn1.setDuration(1000);
mytranslateanimdn1.setStartOffset(1000);
animdn.addAnimation(mytranslateanimdn0);
animdn.addAnimation(mytranslateanimdn1);
mImgDn.startAnimation(animdn);
}
