安卓：开放的对话框中选择音频 [英] Android: open dialog for select audio

问题描述

我需要让用户从自己的媒体库中的一些audiofile的。

I need to allow user to select some audiofile from his media library.

下面就是我想要做的：

        Intent tmpIntent = new Intent(
              Intent.ACTION_PICK,
              android.provider.MediaStore.Audio.Media.EXTERNAL_CONTENT_URI
              );

        startActivityForResult(tmpIntent, 0);

不过，我得到错误：

But I get error:

08-20 17:44:35.444: E/AndroidRuntime(3773): android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.PICK dat=content://media/external/audio/media }

要在安全方面，我也试过 INTERNAL_CONTENT_URI ，但结果是类似的。

To be on the safe side, I also tried INTERNAL_CONTENT_URI, but result is similar.

我怎样才能做到这一点？

How can I achieve this?

UPD：顺便说一句，如果我试图通过URI获得的图像（即 android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI ），那么它的工作原理：像打开的对话​​框打开。

UPD: by the way, if I try to pass URI to get images (i.e. android.provider.MediaStore.Images.Media.INTERNAL_CONTENT_URI), then it works: image open dialog is opened.

UPD2：只是尝试这样的模拟器 - 我的code的作品！但它没有两个设备（SE XPERIA neo和一些宏碁）。但如果我尝试从第二个变种<一个href=\"http://stackoverflow.com/questions/10461065/how-to-pickup-an-audio-files-path-or-uri-from-device-in-android/10461112#10461112\">this回答，然后我得到了所有我现有的文件经理菜单，并用选择音乐呢！但我只是需要写意图打开这个选择音乐。

UPD2: Just tried this on emulator - my code works! But on two devices it doesn't (SE Xperia Neo and some Acer). But if I try the second variant from this answer, then I got menu with all my existing file-managers, and with "Music select" too! But I need to write Intent just to open this "Music select".

推荐答案

好吧，我在LogCat中所看到的，当我打开音乐选择对话框中会发生什么，我得到了我所需要的。这code为我工作：

Well, I have seen in LogCat what happens when I open music select dialog, and I got what I need. This code works for me:

     Intent tmpIntent = new Intent(RingtoneManager.ACTION_RINGTONE_PICKER);
     startActivityForResult(tmpIntent, 0);

如果我想要得到的，也就是说，只通知声音，然后我需要把多余的，就像这样：

If I want to get, say, notifications sounds only, then I need to put extra, just like that:

     Intent tmpIntent = new Intent(RingtoneManager.ACTION_RINGTONE_PICKER);
     tmpIntent.putExtra(RingtoneManager.EXTRA_RINGTONE_TYPE, RingtoneManager.TYPE_NOTIFICATION);
     startActivityForResult(tmpIntent, 0);
