文本抖动效果

几句代码如下:
Java代码 
Animation animation = AnimationUtils.loadAnimation(this, R.anim.shake);  
EditText editText = (EditText) findViewById(R.id.edittext);  
     editText.startAnimation(animation); 

Animation animation = AnimationUtils.loadAnimation(this, R.anim.shake);
EditText editText = (EditText) findViewById(R.id.edittext);
editText.startAnimation(animation);


shake.xml:
里面面的fromXDelta,toXDelta是表示x轴方向的移动距离
Java代码 
<translate xmlns:android="http://schemas.android.com/apk/res/android" 
    android:fromXDelta="0" android:toXDelta="30" android:duration="1000" 
    android:interpolator="@anim/cycle_interpolator" /> 

<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:fromXDelta="0" android:toXDelta="30" android:duration="1000"
android:interpolator="@anim/cycle_interpolator" />


cycleInterpolator.xml文件:
Java代码 
<cycleInterpolator xmlns:android="http://schemas.android.com/apk/res/android" 
    android:cycles="3" />
