如何打开音乐选择器? [英] How to open music picker?

问题描述

在我的应用程序中，我想选择一个可以使用户选择音乐的选择器.我想使用本地android选择器.我使用以下代码打开了本地android音乐选择器:

In my application, I want to make a picker that offers the user the choice to pick a music. I want to use the native android picker. I used the following code to open the native android music picker:

final Intent intent2 = new Intent(Intent.ACTION_PICK);
intent2.setType("audio/*");
startActivityForResult(intent2, 1);

但是当我执行它时，我得到一个ActivityNotFoundException和以下错误消息:

But when I execute it, I get an ActivityNotFoundException and this error message:

您的手机没有可用于选择文件的音乐库.请尝试发送其他类型的文件"

"Your phone has no music gallery that can be used to select a file. Please try sending a different type of files"

我在那做错了吗?

推荐答案

这对我来说效果很好:

public static final int REQ_PICK_AUDIO = 10001;
//------   
Intent audio_picker_intent = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Audio.Media.EXTERNAL_CONTENT_URI);
activity.startActivityForResult(audio_picker_intent, REQ_PICK_AUDIO);

更通用的Intent.ACTION_GET_CONTENT可以为用户提供许多选择活动的选项，以选择音频文件(Astro文件管理器等).但是，用户可以选择任何文件，而不必选择音频文件.我想要一个仅允许用户从其媒体中选择音频文件的文件.这就是窍门.

The more general intent with Intent.ACTION_GET_CONTENT can present the user with a number of options for activities to pick an audio file (Astro file manager, etc.). However, the user could select any file, not necessarily an audio file. I wanted one that simply allowed the user to select an audio file from their media. This did the trick.
