在哪里放置媒体资源并启动媒体播放器? [英] Where to put media resource and start media player?

问题描述

我想使用标准 Android 媒体播放器在 Xamarin 应用中播放歌曲.

我有两个问题无法回答:

1. 我在这里放置媒体文件(.mp3 文件)或如何链接到该文件(它也保存在我的 SD 卡上)我尝试将其保存在原始文件夹中，但似乎没有上班
2. 如何正确启动播放器?要么我的代码不起作用，要么播放器找不到该文件，因为它没有正确存储.

然而，这是我用来准备媒体播放器的方法:

受保护的 MediaPlayer 播放器；公共无效StartPlayer(){如果(玩家==空){播放器 = 新媒体播放器()；player.SetDataSource("Ressources.raw.test");玩家准备()；player.Start();text = "运行";} 别的 {player.Reset();player.SetDataSource("Ressources.raw.test");玩家准备()；player.Start();}}

解决方案

我尝试将其保存在原始文件夹中，但这似乎不起作用

您不能直接使用字符串Ressources.raw.test"作为DataSource.如果您需要播放 Resource/Raw 文件夹中的歌曲，这里有两种解决方案.

解决方案 1:

您可以尝试使用 MediaPlayer.Create(Context context, int resid)方法:

<块引用>

为给定资源 ID 创建 MediaPlayer 的便捷方法.成功后，prepare() 将已被调用，不得再次调用.

用途:

MediaPlayer player = MediaPlayer.Create(this, Resource.Raw.test);player.Start();

解决方案 2:

将您的 Resource/Raw/test 路径转换为 ​​Android.Net.Uri:

player = new MediaPlayer();Android.Net.Uri uri = Android.Net.Uri.Parse("android.resource://" + PackageName + "/" + Resource.Raw.test);player.SetDataSource(this, uri2);玩家准备()；player.Start();

<块引用>

我如何链接到文件(它也保存在我的 SD 卡上)

解决方案:

尝试使用 SetDataSource(Context context, Uri uri)方法，例如:

player = new MediaPlayer();//我的文件路径是Path == file:///storage/emulated/0/netease/cloudmusic/Music/love.MP3var uri = Android.Net.Uri.Parse("file://" + Android.OS.Environment.ExternalStorageDirectory + "/netease/cloudmusic/Music/love.MP3");player.SetDataSource(this, uri);玩家准备()；player.Start();

I want to play a song in a Xamarin app using the standard android media player.

I've got two questions that i haven't been able to answer myself:

1. Here do I put the media file (.mp3-file) or how do i link to the file (it's also saved on my SD-Card) I tried saving it in the raw-folder, but that doesn't seem to work
2. How do I correctly launch the player? Either my code doesn't work or the player doesn't find the file because it isn't stored correctly.

However, that's the method I use to prepare the media player:

protected MediaPlayer player;

public void StartPlayer() {
    if (player == null) {
        player = new MediaPlayer();
        player.SetDataSource("Ressources.raw.test");
        player.Prepare();
        player.Start();
        text = "Running";
    } else {
        player.Reset();
        player.SetDataSource("Ressources.raw.test");
        player.Prepare();
        player.Start();
    }
}

解决方案

I tried saving it in the raw-folder, but that doesn't seem to work

You can't directly use string "Ressources.raw.test" as the DataSource. If you need play a song from Resource/Raw folder, here is two solutions.

Solution 1:

You could try using MediaPlayer.Create(Context context, int resid) method:

Convenience method to create a MediaPlayer for a given resource id. On success, prepare() will already have been called and must not be called again.

Usage：

MediaPlayer player = MediaPlayer.Create(this, Resource.Raw.test);
player.Start();

Solution 2:

Convert your Resource/Raw/test path to Android.Net.Uri:

player = new MediaPlayer();
Android.Net.Uri uri = Android.Net.Uri.Parse("android.resource://" + PackageName + "/" + Resource.Raw.test);
player.SetDataSource(this, uri2);
player.Prepare();
player.Start();

how do I link to the file (it's also saved on my SD-Card)

Solution:

Try using SetDataSource (Context context, Uri uri) method, for example:

player = new MediaPlayer();

//My file path is Path == file:///storage/emulated/0/netease/cloudmusic/Music/love.MP3
var uri = Android.Net.Uri.Parse("file://" + Android.OS.Environment.ExternalStorageDirectory + "/netease/cloudmusic/Music/love.MP3");

player.SetDataSource(this, uri);
player.Prepare();
player.Start();
