How to get Ringtone name in Android?
提问by stacksonstacks
I'm allowing my user to pick a ringtone for notifications in my app. I want to store the URI of the sound along with the human readable title of the sound.
我允许我的用户在我的应用程序中为通知选择铃声。我想存储声音的 URI 以及声音的人类可读标题。
So far the URI code works great:
到目前为止，URI 代码运行良好：
Uri uri = intent.getParcelableExtra(RingtoneManager.EXTRA_RINGTONE_PICKED_URI);
But when I try to get the title, and set it as a button text, I don't get anything. Seems to have no title?
但是当我尝试获取标题并将其设置为按钮文本时，我什么也没得到。好像没有标题？
String title = intent.getParcelableExtra(RingtoneManager.EXTRA_RINGTONE_TITLE);
button.setText(title);
But my button text is empty. If I do:
但是我的按钮文本是空的。如果我做：
button.setText(uri.toString());
then I see the uri perfectly. Should I just try to get the title from the URI? Thanks
然后我完美地看到了uri。我应该尝试从 URI 中获取标题吗？谢谢

This should get it:
这应该得到它：
Ringtone ringtone = RingtoneManager.getRingtone(this, uri);
String title = ringtone.getTitle(this);
Refer to http://developer.android.com/reference/android/media/Ringtone.htmlfor the documentation, but the short story: Ringtone.getTitle(Context ctx);
有关文档，请参阅http://developer.android.com/reference/android/media/Ringtone.html，但简短的故事： Ringtone.getTitle(Context ctx);

I had problems with 'MediaPlayer finalized without being released'. I use this:
我遇到了“MediaPlayer 最终确定但未发布”的问题。我用这个：
Cursor returnCursor = getContentResolver().query(uri, null, null, null, null);
returnCursor.moveToFirst();
String title = returnCursor.getString(returnCursor.getColumnIndex(OpenableColumns.DISPLAY_NAME));
returnCursor.close();
Refer to https://developer.android.com/training/secure-file-sharing/retrieve-info.htmlfor the documentation.

I personally had a serious performance problem when I tried the accepted answer, it took about 2 seconds to just load a list of 30 ringtones. I changed it a bit and it works about 10x faster:
当我尝试接受的答案时，我个人遇到了严重的性能问题，加载一个包含 30 个铃声的列表需要大约 2 秒钟。我对其进行了一些更改，它的运行速度提高了大约 10 倍：
uri = ringtoneMgr.getRingtoneUri(cursor.getPosition());
ContentResolver cr = getContext().getContentResolver();
String[] projection = {MediaStore.MediaColumns.TITLE};
String title;
Cursor cur = cr.query(uri, projection, null, null, null);
if (cur != null) {
if (cur.moveToFirst()) {
title = cur.getString(0);
cur.close();
