Question

我设置了铃声，它可以正常工作但是＆＃34; .MediaColumns.TITLE＆＃34;和＆＃34; .Media.ARTIST＆＃34;不工作。我已设置铃声，然后检查。显示文件名而不是＆＃34;标题名称＆＃34;。

我的代码;

public boolean setRingtone(int p, String s) {

    String path = Environment.getExternalStorageDirectory().getPath()
            + "/sdcard/media/audio/ringtones/";
    String filename = s+'.mp3';

    boolean exists = (new File(path)).exists();
    if (!exists) {
        new File(path).mkdirs();
    }

    File k = new File(path, filename);

    ContentValues values = new ContentValues();
    values.put(MediaStore.MediaColumns.DATA, k.getAbsolutePath());
    values.put(MediaStore.MediaColumns.TITLE, "Title Name");
    values.put(MediaStore.MediaColumns.MIME_TYPE, "audio/mp3");
    values.put(MediaStore.Audio.Media.ARTIST, "Ringtones");
    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(k.getAbsolutePath());

    getContentResolver().delete(uri,MediaStore.MediaColumns.DATA + "=\"" + k.getAbsolutePath() + "\"", null);

    Uri newUri = getContentResolver().insert(uri,values);
    RingtoneManager.setActualDefaultRingtoneUri(SingleListItem.this,RingtoneManager.TYPE_RINGTONE,newUri);

    String desc= "Ringtone has been set";

    Toast.makeText(getApplicationContext(), desc, Toast.LENGTH_LONG).show();
    return true;

}

你的插入看起来是正确的...我使用了几乎相同的代码，它的工作原理。它在哪里显示文件名而不是＆＃34;标题名称＆＃34;？在手机设置中或再次查询数据库中的媒体条目时？如果是在查询时，请确保索引到正确的列以获取字符串：

Uri ringtoneUri = ...however you are getting the URI...
String[] retCol = { MediaStore.MediaColumns.TITLE };
Cursor cur =   context.getContentResolver().query(ringtoneUri,retCol,null,null, null);
if (cur.getCount() > 0) {
    cur.moveToFirst();
    String name = cur.getString(cur.getColumnIndex( MediaStore.MediaColumns.TITLE ));
    //Do something with name...
}
cur.close();

Android RingtoneManager“标题”和“艺术家”信息
