对于Android应用开发来说，手机铃声是一个非常重要的需求，网上查了很多例子，都有点问题，综合几个自己写了个可以设置铃声、通知声音、闹钟声音和所有声音功能的方法。
首先写一个常量类(定义想要设置为那种铃声的标示)：
AppConstant.java
public interface AppConstant {
public static final int RINGTONE = 0; //铃声
public static final int NOTIFICATION = 1; //通知音
public static final int ALARM = 2; //闹钟
public static final int ALL = 3; //所有声音
}
public interface AppConstant {
public static final int RINGTONE = 0; //铃声
public static final int NOTIFICATION = 1; //通知音
public static final int ALARM = 2; //闹钟
public static final int ALL = 3; //所有声音
}
此方法需要传入想要设置为铃声的全路径（如：/mnt/sdcard/mp3/a.mp3 ），和想要设置为那种铃声的标示：
private void setVoice(String path2,int id)

3 {
4
5 ContentValues cv = new ContentValues();
6
7 Uri newUri = null;
8
9 Uri uri = MediaStore.Audio.Media.getContentUriForPath(path2);
10
11 // 查询音乐文件在媒体库是否存在
12
13 Cursor cursor = this.getContentResolver().query(uri, null,
MediaStore.MediaColumns.DATA + "=?", new String[]
{ path2 },null);
14
15 if (cursor.moveToFirst() && cursor.getCount() > 0)
16
17 {
18
19 String _id = cursor.getString(0);
20
21 switch (id) {
22
23 case AppConstant.RINGTONE:
