android.view.InflateException：二进制XML文件第9行：二进制XML文件第9行：错误夸大类

Question

我到处都在寻找，但找不到针对此错误的任何解决方案。

我正在使用ExoPlayer进行实时视频流传输。而且我的应用每次运行时都会崩溃。如果您能帮助我，我会很高兴。

我想它应该在XML文件中的某个位置，但是我不明白这是什么意思。XML：

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

<com.devbrackets.android.exomedia.ui.widget.VideoView
    android:id="@+id/video_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    app:useDefaultControls="true"/>

</androidx.constraintlayout.widget.ConstraintLayout>

MainActivity文件：

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    final ProgressDialog progressDialog = new ProgressDialog(MainActivity.this);
    progressDialog.setMessage("Please Wait");
    progressDialog.setCancelable(false);
    progressDialog.show();

    MediaController mediaController = new MediaController(this);
    mediaController.setAnchorView(videoView);
    videoView.setMediaController(mediaController);

    videoView.setVideoURI(Uri.parse("Here's path"));
    videoView.start();

    videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
        @Override
        public void onPrepared(MediaPlayer mp) {
            progressDialog.dismiss();
        }
    });
  }
}

如果可以，请向我详细说明此错误，因为如果我再次遇到此问题，则可以轻松解决。

编辑：伙计们，谢谢大家！我解决了这个问题。

解决方案：

• VideoView videoView = findViewById(R.id.video_view);
• 并且我根据我的packageName更改了VideoView的路径。

Answer 1

请检查是否

<com.devbrackets.android.exomedia.ui.widget.VideoView
android:id="@+id/video_view"
android:layout_width="match_parent"
android:layout_height="match_parent"
app:useDefaultControls="true"/>

VideoView的路径根据您的packageName是正确的。

Answer 2

当我根据用户的反馈检查此文件是否完整时，请尝试这样的另一个视频视图

 <VideoView 
     android:layout_height="fill_parent"
     android:layout_width="fill_parent" 
     android:id="@+id/VideoView" />

Answer 3

确保您添加了库依赖项，并且必须在此行中添加它

VideoView vedioView = findViewById(R.id.video_view);

使用前vedioView。我认为它将解决您的问题
