Android 代碼設置來電鈴聲

一、若是讀到的是音頻文件路徑，須要先將音樂文件插入到多媒體庫。

//設置--鈴聲的具體方法
    public void setMyRingtone(String path)
    {
      File sdfile = new File(path);
      ContentValues values = new ContentValues();
      values.put(MediaStore.MediaColumns.DATA, sdfile.getAbsolutePath());
      values.put(MediaStore.MediaColumns.TITLE, sdfile.getName());
      values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/*");
      values.put(MediaStore.Audio.Media.IS_RINGTONE, true);
      values.put(MediaStore.Audio.Media.IS_NOTIFICATION, false);
      values.put(MediaStore.Audio.Media.IS_ALARM, false);
      values.put(MediaStore.Audio.Media.IS_MUSIC, false);

      Uri uri = MediaStore.Audio.Media.getContentUriForPath(sdfile.getAbsolutePath());
      Uri newUri = this.getContentResolver().insert(uri, values);
      RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_RINGTONE, newUri);
      Toast.makeText( getApplicationContext (),"設置來電鈴聲成功！", Toast.LENGTH_SHORT ).show();
      System.out.println("setMyRingtone()-----鈴聲");
    }

  //設置--提示音的具體實現方法
    public void setMyNotification(String path)
    {

      File sdfile = new File(path);
      ContentValues values = new ContentValues();
      values.put(MediaStore.MediaColumns.DATA, sdfile.getAbsolutePath());
      values.put(MediaStore.MediaColumns.TITLE, sdfile.getName());
      values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/*");
      values.put(MediaStore.Audio.Media.IS_RINGTONE, false);
      values.put(MediaStore.Audio.Media.IS_NOTIFICATION, true);
      values.put(MediaStore.Audio.Media.IS_ALARM, false);
      values.put(MediaStore.Audio.Media.IS_MUSIC, false);

      Uri uri = MediaStore.Audio.Media.getContentUriForPath(sdfile.getAbsolutePath());
      Uri newUri = this.getContentResolver().insert(uri, values);

      RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_NOTIFICATION, newUri);
      Toast.makeText( getApplicationContext (),"設置通知鈴聲成功！", Toast.LENGTH_SHORT ).show();
      System.out.println("setMyNOTIFICATION-----提示音");
    }
  //設置--鬧鈴音的具體實現方法
  public void setMyAlarm(String path)
    {
      File sdfile = new File(path);
      ContentValues values = new ContentValues();
      values.put(MediaStore.MediaColumns.DATA, sdfile.getAbsolutePath());
      values.put(MediaStore.MediaColumns.TITLE, sdfile.getName());
      values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/*");
      values.put(MediaStore.Audio.Media.IS_RINGTONE, false);
      values.put(MediaStore.Audio.Media.IS_NOTIFICATION, false);
      values.put(MediaStore.Audio.Media.IS_ALARM, true);
      values.put(MediaStore.Audio.Media.IS_MUSIC, false);

      Uri uri = MediaStore.Audio.Media.getContentUriForPath(sdfile.getAbsolutePath());
      Uri newUri = this.getContentResolver().insert(uri, values);
      RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_ALARM, newUri);
      Toast.makeText( getApplicationContext (),"設置鬧鐘鈴聲成功！", Toast.LENGTH_SHORT ).show();
      System.out.println("setMyNOTIFICATION------鬧鈴音");
    }

二、若是讀取多媒體庫的音頻文件，設爲鈴聲，使用如下方式：

首先寫一個常量類(定義想要設置爲那種鈴聲的標示)：

AppConstant.java
 public interface AppConstant {
     public static final int RINGTONE = 0;                   //鈴聲

     public static final int NOTIFICATION = 1;               //通知音

     public static final int ALARM = 2;                      //鬧鐘

    public static final int ALL = 3;                        //全部聲音

}

此方法須要傳入想要設置爲鈴聲的全路徑（如：/mnt/sdcard/mp3/a.mp3 ），和想要設置爲那種鈴聲的標示：

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        // 查詢音樂文件在媒體庫是否存在
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            // 把須要設爲鈴聲的歌曲更新鈴聲庫
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          // 一下爲關鍵代碼：
90
91            switch (id) {
92
93               case AppConstant.RINGTONE:
94
95                   RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_RINGTONE, newUri);
96

104
105               case AppConstant.ALARM:
106
107                  RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_ALARM, newUri);
108
109                   break;

114

116
117
118
119               default:

121                   break;
122
123            }
124
125

133        }
135     }
