我如何更改铃声在机器人编程？ [英] How can I change the ringtone in android programmatically?

问题描述

我想编写一个应用程序，基于他们的位置（除其他事项外）将改变用户的铃声。

I'm trying to write an app that (among other things) will change the user's ringtone based on their location.

不过，我有困难，从我的应用程序设置我的手机铃声。我已经能够显示手机的铃声列表，并一直在使用下面的code，试图设定铃声：

However, I'm having difficulty setting the ringtone of my phone from within my app. I've been able to display a list of the phone's ringtones, and have been using the following code to try and set the ringtone:

RingtoneManager.setActualDefaultRingtoneUri(applicationContext, 
      RingtoneManager.TYPE_RINGTONE,
      MediaStore.Audio.Media.getContentUriForPath(settings.getRingtoneURI()));

Settings.System.putString(c.getContentResolver(), Settings.System.RINGTONE, 
      settings.getRingtoneURI());

在这里settings.getRingtoneURI（）返回一个字符串所需铃声的URI。

where settings.getRingtoneURI() returns a string with the URI of the desired ringtone.

当我运行这个，我收到没有错误，但铃声也不会改变。

When I run this, I receive no errors but the ringtone does not change.

任何意见？

推荐答案

请问您的应用程序的权限android.permission.WRITE_SETTINGS？

Does your app have permission android.permission.WRITE_SETTINGS?
