Android 微信摇一摇播放音乐简单功能实现
在这里需要设置一个权限：
uses-permission android:name=“android.permission.VIBRATE”
然后来看一下，mainactivity.xml中的代码：
mipmap-hdpi文件夹下需要放入maintivity.xml相对应的图片，这里就不多演示了
因为需要播放音乐所以这里需要建一个raw文件夹，这里面是放音乐资源的，也不过多演示了
values文件夹下的colors.ml与Strings.xml分别要写的代码：
colors.xml是设置颜色用的
String.xml可以放入字符串：
接下来就是最为重要的mainactivity里面的代码：
