android 中的抖动效果(仿苹果)

三种抖动效果
1. 左右抖动
2. 上下抖动

核心代码:

res/anim/cycle.xml

<?xml version="1.0" encoding="utf-8"?>
<cycleInterpolator xmlns:android="http://schemas.android.com/apk/res/android" 
android:cycles="20" />

res/anim/shage_x.xml

<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android" 
android:fromXDelta="0" 
android:toXDelta="10" 
android:duration="1000" 
android:interpolator="@anim/cycle" />

res/anim/shage_y.xml


<?xml version="1.0" encoding="utf-8"?>
<translate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="1000"
    android:fromYDelta="0"
    android:interpolator="@anim/cycle"
    android:toYDelta="10" >

</translate>


3. 仿苹果长按时的抖动

res/anim/anim.xml

<?xml version="1.0" encoding="utf-8"?>
<rotate xmlns:android="http://schemas.android.com/apk/res/android"
    android:duration="180"
    android:fromDegrees="-2"
    android:pivotX="100%"
    android:pivotY="100%"
    android:repeatCount="infinite"
    android:repeatMode="reverse"
    android:toDegrees="2" />


代码中使用方法:

				Animation shake = AnimationUtils.loadAnimation(
						ShakeDemoActivity.this, R.anim.anim);
				shake.reset();
				shake.setFillAfter(true);
				imageview.startAnimation(shake);
