【Activity、service】点击不同的图片播放不同的声音

一下，我只把主要的代码贴出来给大家，如果哪里写的不好，希望大家能多多指教，灰常感谢。

/** 定义播放小孩声音的ACTION */
public static String SOUND_ACTION = "com.vtion.ym.box.sound";

XxxActivity.java Activity里面中的代码

View Code

 1     @Override
 2     public void onClick(View v) {
 3         Intent intent = new Intent(Constant.SOUND_ACTION);
