怎样使android的view动画循环弹动

在res中建立文件夹anim,分别写下cycles.xml,shake1.xml,shake2.xml

怎样使android的view动画循环弹动

cycles.xml:

 <?xml version="1.0" encoding="utf-8"?>
<!-- android:cycles代表移动的速度 -->
<cycleInterpolator xmlns:android="http://schemas.android.com/apk/res/android"
android:cycles="1" />

shake1.xml:

 <?xml version="1.0" encoding="utf-8"?>
<!--水平移动 -->
<!--android:duration代表运行时间 -->
<!-- android:fromXDelta代表起始横坐标位置 (0,0)-->
<!-- android:toXDelta代表离横坐标起始位置的X距离为100 (100,0)-->
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="3000"
android:fromXDelta="0.0"
android:toXDelta="100.0"
android:interpolator="@anim/cycles"/>

shake2.xml:

 <?xml version="1.0" encoding="utf-8"?>
<!--垂直移动 -->
<!--android:duration代表运行时间 -->
<!-- android:fromXDelta代表起始纵坐标位置 (0,0)-->
<!-- android:toXDelta代表离横坐标起始位置的Y距离为100(0,100)-->
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="3000"
android:fromYDelta="0.0"
android:toYDelta="100.0"
android:interpolator="@anim/cycles"/>
