正文

String paths = mCurrentPath + MountPointManager.SEPARATOR

+ mAdapter.getCheckedFileInfoItemsList().get(0).getFileName();

settingRingertone(paths);

private void settingRingertone(String path) {

ContentValues cv = new ContentValues();

Uri uri = MediaStore.Audio.Media.EXTERNAL_CONTENT_URI;

Cursor cursor = this.getContentResolver().query(uri,

null, MediaStore.MediaColumns.DATA + "=?", new String[] { path }, MediaStore.Audio.Media.DEFAULT_SORT_ORDER);

if (cursor.moveToFirst()) {

String _id = cursor.getString(0);

cv.put(AudioColumns.IS_RINGTONE, true);

cv.put(AudioColumns.IS_MUSIC, true);

// Insert the bell library

getContentResolver().update(uri, cv,MediaStore.MediaColumns.DATA + "=?", new String[] { path });

Uri newUri = ContentUris.withAppendedId(uri, Long.valueOf(_id));

// Set up the bell

RingtoneManager.setActualDefaultRingtoneUri(this,RingtoneManager.TYPE_RINGTONE, newUri );

Toast.makeText(this, R.string.ring_set_succeed, Toast.LENGTH_SHORT).show();

}

}如果不成功请检查_id的值。
