使用 VideoView 时获取 java.io.FileNotFoundException

Question

我有以下代码：

   VideoView videoView = (VideoView)findViewById(R.id.instructionsvideo);
   assert videoView != null;
   videoView.setVideoPath("android.resource://" + getPackageName() + R.raw.testnatureclip);
   videoView.start();

“testnatureclip”位于原始文件夹中：

出于某种原因，在我构建项目后，文件变为红色。

这是我得到的错误： com.roymunson.vroy.copypastakeyboard W/MediaPlayer: Couldn't open file on client side; trying server side: java.io.FileNotFoundException: No package found for authority: android.resource://com.roymunson.vroy.copypastakeyboard2131165184

mp4应该是H.264格式编码的，不知道我用的在线编码服务有没有用。

此外，如果这很重要，视频视图与文件的尺寸不同。

问题是什么？文件路径不正确，还是我在初始化视频视图时缺少某些元素？

更新一：

使用 User8 的解决方案，我收到以下错误：

Answer 1

我找到了2个解决方案：

String uriPath = "android.resource://" + getPackageName() + "/raw/testnatureclip";
Uri uri = Uri.parse(uriPath);
videoView.setVideoURI(uri);

或者

videoView.setVideoURI(Uri.parse("android.resource://ABSOLUTE_PACKAGE_NAME/" + R.raw.testnatureclip));
