Android仿Iphone图标抖动效果

最近闲来无聊，研究了一下IPhone桌面图标的抖动，网上有一个类似的事例，但是我看来效果实在不佳，自己也来写一个玩玩，当然代码很乱，杂乱无章，不满意的别骂我啊，当然也欢迎一起交流啊，嚯嚯

首先是JAVA代码ShakeTestActivity.java：

package com.android.shake;import android.app.Activity;import android.os.Bundle;import android.util.DisplayMetrics;import android.view.animation.Animation;import android.view.animation.Animation.AnimationListener;import android.view.animation.RotateAnimation;import android.widget.TextView;import android.view.View;import android.view.Window;public class ShakeTestActivity extends Activity implements View.OnClickListener {    private TextView mtv0;

       } else if (c == 1) {            rotate = DEGREE_1;        } else if (c == 2) {            rotate = DEGREE_2;        } else if (c == 3) {            rotate = DEGREE_3;        } else {            rotate = DEGREE_4;

           mStartShake = false;        }    }}

然后是main.xml文件

string.xml

<?xml version="1.0" encoding="utf-8"?><resources>    <string name="hello">Hello World</string>    <string name="app_name">ShakeTest</string></resources>

测试机的分辨率是320x480，640x960，其他分辨率显示效果不佳自行调整吧
