在媒体播放器中使用来自 android 项目的文件 [英] Using file from android project in media Player

问题描述

enter image description here i have a mobile application that is dedicated to playing articles using MediaPlayer. I am trying to set the pause between individual sentences however i keep getting null reference at the pausesPlayer so accesing the mp3 files in my droid project from shared project must be wrong. Please do you have any experience with how to acess the file in droid without Main Activity

MediaPlayer.Create(MainActivity.Instance, Resource.Raw.silent_1);

public static void SetPauseBetweenSentences(int timeout)
{
    lock (syncRoot)
    {
        pausesPlayer = new MediaPlayer();
        if (timeout != 0)
        {
            switch (timeout)
            {
                case 1:
                    pausesPlayer = MediaPlayer.Create(Android.App.Application.Context, Android.Net.Uri.Parse("AT.Droid/Resources/raw/silent_1"));
                    break;
                case 2:
                    pausesPlayer = MediaPlayer.Create(Android.App.Application.Context, Android.Net.Uri.Parse("AT.Droid/Resources/raw/silent_2"));
                    break;
                case 3:
                    pausesPlayer = MediaPlayer.Create(Android.App.Application.Context, Android.Net.Uri.Parse("AT.Droid/Resources/raw/silent_3"));
                    break;
                case 4:
                    pausesPlayer = MediaPlayer.Create(Android.App.Application.Context, Android.Net.Uri.Parse("AT.Droid/Resources/raw/silent_4"));
                    break;
                case 5:
                    pausesPlayer = MediaPlayer.Create(Android.App.Application.Context, Android.Net.Uri.Parse("AT.Droid/Resources/raw/silent_5"));
                    break;
            }
            pausesPlayer.Start();
        }
    }
}

I have tried

pausesPlayer = MediaPlayer.Create(Android.App.Application.Context, Android.Net.Uri.Parse("android.resource://AT.Droid/Resources/raw/silent_1"));
    

and

pausesPlayer = MediaPlayer.Create(Android.App.Application.Context, Android.Net.Uri.Parse("android.resource://AT/Resources/raw/silent_1"));

解决方案

From the document, you can use:

Convenience method to create a MediaPlayer for a given resource id.

public static Android.Media.MediaPlayer Create (Android.Content.Context context, int resid);

And in your case, it is:

MediaPlayer player = MediaPlayer.Create(this, Resource.Raw.silent_1);

For more solutions, you can have a look at this thread.
