android.view.InflateException：二进制 XML 文件第 9 行：二进制 XML 文件第 9 行：膨胀 class 时出错

Question

我到处找，但找不到解决此错误的方法。

我正在使用 ExoPlayer 进行实时视频流。每次运行我的应用程序都会崩溃。如果你能帮助我，我会很高兴。

我想它应该在 XML 文件中的某处，但我不明白所有这些错误是什么意思。 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();
        }
    });
  }
}

如果你能更详细地解释这个错误，因为如果我再次遇到这个问题，我可以很容易地解决它。

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);
并且我根据我的包名称更改了 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 的路径根据您的包名是正确的。

Answer 2

根据用户的反馈，我检查此文件不完整，请尝试另一个视频视图

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

Answer 3

确保添加库依赖项并且必须添加这一行

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

使用前 vedioView。我想它会解决你的问题

Answer 4

你必须覆盖构造函数

public VideoPlayerView(Context context, AttributeSet attributeSet) {
super(context, attributeSet);
}

这将解决您的问题。
