手机输入框抖动效果 和 震动效果

首先分析  输入框抖动 效果 实际上 就是一个动画  左右循环 抖动  

Animation animation = AnimationUtils.loadAnimation(this, R.anim.shake);

//下面的 可以设置 动画的 插入器  用函数来控制动画的动作

    /*                   animation.setInterpolator(new Interpolator() {

@Override
public float getInterpolation(float input) {
// TODO Auto-generated method stub
return 0;
}
});*/
edt_select_number.startAnimation(animation);

上面 2行 代码设置 动画  其中R.anim.shake  是 一个抖动动画的  xml文件  从系统中得到的  自己也可以 自定义  

R.anim.shake

<cycleInterpolator xmlns:android="http://schemas.android.com/apk/res/android" android:cycles="7" />

其中  插入器可以 自定义 就相当于  初中学的函数

而对于震动效果  需要一个private Vibrator vibrator;  

vibrator = (Vibrator) getSystemService(VIBRATOR_SERVICE);  这是一个系统服务  

由于 震动效果  会影响用户的使用 所以必须 添加相应的权限  

<uses-permission android:name="android.permission.VIBRATE"/>

 vibrator.vibrate(2000);//振动两秒钟

   //-1不重复，非-1为从pattern的指定下标开始重复

   long[] pattern = {100,200,100,200,50,50};  //这个数组  是控制  震动的变化的  

   vibrator.vibrate(pattern, 1);
