1、如果讀到的是音頻文件路徑，需要先將音樂文件插入到多媒體庫。
Java代碼
//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");
}
2、如果讀取多媒體庫的音頻文件，設為鈴聲，使用以下方式：
首先寫壹個常量類（定義想要設置為那種鈴聲的標示）：
AppConstant.java
Java代碼
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; //所有聲音
}
此方法需要傳入想要設置為鈴聲的全路徑（如：/mnt/sdcard/mp3/a.mp3），和想要設置為哪種鈴聲的標示：
Java代碼
private void setVoice(String path2,int id)
{
ContentValues cv = new ContentValues();
Uri newUri = null;
Uri uri = MediaStore.Audio.Media.getContentUriForPath(path2);
// 查詢音樂文件在媒體庫是否存在
Cursor cursor = this.getContentResolver().query(uri, null, MediaStore.MediaColumns.DATA + "=?", new String[] { path2 },null);
if (cursor.moveToFirst() && cursor.getCount() > 0)
{
String _id = cursor.getString(0);
switch (id) {
case AppConstant.RINGTONE:
cv.put(MediaStore.Audio.Media.IS_RINGTONE, true);
cv.put(MediaStore.Audio.Media.IS_NOTIFICATION, false);
cv.put(MediaStore.Audio.Media.IS_ALARM, false);
cv.put(MediaStore.Audio.Media.IS_MUSIC, false);
break;
case AppConstant.NOTIFICATION:
cv.put(MediaStore.Audio.Media.IS_RINGTONE, false);
cv.put(MediaStore.Audio.Media.IS_NOTIFICATION, true);
cv.put(MediaStore.Audio.Media.IS_ALARM, false);
cv.put(MediaStore.Audio.Media.IS_MUSIC, false);
break;
case AppConstant.ALARM:
cv.put(MediaStore.Audio.Media.IS_RINGTONE, false);
cv.put(MediaStore.Audio.Media.IS_NOTIFICATION, false);
cv.put(MediaStore.Audio.Media.IS_ALARM, true);
cv.put(MediaStore.Audio.Media.IS_MUSIC, false);
break;
case AppConstant.ALL:
cv.put(MediaStore.Audio.Media.IS_RINGTONE, true);
cv.put(MediaStore.Audio.Media.IS_NOTIFICATION, true);
cv.put(MediaStore.Audio.Media.IS_ALARM, true);
cv.put(MediaStore.Audio.Media.IS_MUSIC, false);
break;
default:
break;
}
// 把需要設為鈴聲的歌曲更新鈴聲庫
getContentResolver().update(uri, cv, MediaStore.MediaColumns.DATA + "=?",new String[] { path2 });
newUri = ContentUris.withAppendedId(uri, Long.valueOf(_id));
// 壹下為關鍵代碼：
switch (id) {
case AppConstant.RINGTONE:
RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_RINGTONE, newUri);
break;
case AppConstant.NOTIFICATION:
RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_NOTIFICATION, newUri);
break;
case AppConstant.ALARM:
RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_ALARM, newUri);
break;
case AppConstant.ALL:
RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_ALL, newUri);
break;
default:
break;
}
//播放鈴聲
//Ringtone rt = RingtoneManager.getRingtone(this, newUri);
//rt.play();
}
}
