Android手机铃声代码实现
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）：- 1 AppConstant.java 2 3 public interface AppConstant { 4 5 6 7 public static final int RINGTONE = 0; //铃声 8 9 public static final int NOTIFICATION = 1; //通知音10 11 public static final int ALARM = 2; //闹钟12 13 public static final int ALL = 3; //所有声音14 15 }此方法需要传入想要设置为铃声的全路径（如：/mnt/sdcard/mp3/a.mp3 ），
- 1 private void setVoice(String path2,int id) 2 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: 24 25 cv.put(MediaStore.Audio.Media.IS_RINGTONE, true); 26 27 cv.put(MediaStore.Audio.Media.IS_NOTIFICATION, false); 28 29 cv.put(MediaStore.Audio.Media.IS_ALARM, false); 30 31 cv.put(MediaStore.Audio.Media.IS_MUSIC, false); 32 33 break; 34 35 case AppConstant.NOTIFICATION: 36 37 cv.put(MediaStore.Audio.Media.IS_RINGTONE, false); 38 39 cv.put(MediaStore.Audio.Media.IS_NOTIFICATION, true); 40 41 cv.put(MediaStore.Audio.Media.IS_ALARM, false); 42 43 cv.put(MediaStore.Audio.Media.IS_MUSIC, false); 44 45 break; 46 47 case AppConstant.ALARM: 48 49 cv.put(MediaStore.Audio.Media.IS_RINGTONE, false); 50 51 cv.put(MediaStore.Audio.Media.IS_NOTIFICATION, false); 52 53 cv.put(MediaStore.Audio.Media.IS_ALARM, true); 54 55 cv.put(MediaStore.Audio.Media.IS_MUSIC, false); 56 57 break; 58 59 case AppConstant.ALL: 60 61 cv.put(MediaStore.Audio.Media.IS_RINGTONE, true); 62 63 cv.put(MediaStore.Audio.Media.IS_NOTIFICATION, true); 64 65 cv.put(MediaStore.Audio.Media.IS_ALARM, true); 66 67 cv.put(MediaStore.Audio.Media.IS_MUSIC, false); 68 69 break; 70 71 72 73 default: 74 75 break; 76 77 } 78 79 80 81 // 把需要设为铃声的歌曲更新铃声库 82 83 getContentResolver().update(uri, cv, MediaStore.MediaColumns.DATA + "=?",new String[] { path2 }); 84 85 newUri = ContentUris.withAppendedId(uri, Long.valueOf(_id)); 86 87 88 89 // 一下为关键代码： 90 91 switch (id) { 92 93 case AppConstant.RINGTONE: 94 95 RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_RINGTONE, newUri); 96 97 break; 98 99 case AppConstant.NOTIFICATION:100 101 RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_NOTIFICATION, newUri);102 103 break;104 105 case AppConstant.ALARM:106 107 RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_ALARM, newUri);108 109 break;110 111 case AppConstant.ALL:112 113 RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_ALL, newUri);114 115 break;116 117 118 119 default:120 121 break;122 123 }124 125 126 127 //播放铃声128 129 // Ringtone rt = RingtoneManager.getRingtone(this, newUri);130 131 // rt.play();132 133 }134 135 }
