在 VideoView [Android] 中播放来自 url 的视频

Question

我发现了类似的问题，但对我没有任何帮助。我尝试从 url:

播放视频

http://videocdn.bodybuilding.com/video/mp4/62000/62792m.mp4

我的java代码：

VideoView videoView= (VideoView)findViewById(R.id.exerciseVideo);
    Uri uri = Uri.parse(TEST_URL);
    videoView.setVideoURI(uri);
    videoView.requestFocus();
    videoView.start();

当我运行应用程序在 activity 中不显示任何内容并且 IDE 不显示任何错误。有什么想法吗？

编辑：

我的 activity 我想显示视频的地方：

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

Answer 1

试试这个代码。这个代码非常适合我。

VideoView videoView = findViewById(R.id.videoView);
videoView.setVideoPath("http://videocdn.bodybuilding.com/video/mp4/62000/62792m.mp4");
videoView.start();

Answer 2

据我所知，您不应使用 wrap_content 作为 VideoView 高度。 VideoView 视频缓存后未自行调整大小

Answer 3

请为他们添加互联网权限将 layout_height wrap_content 更改为匹配父项。这是这个问题的代码

public class MainActivity extends Activity {
    private ProgressDialog bar;
    private String path="https://videocdn.bodybuilding.com/video/mp4/62000/62792m.mp4";
    private MediaController ctlr;
    private VideoView videoView;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        getWindow().setFormat(PixelFormat.TRANSLUCENT);
        setContentView(R.layout.activity_main);
      bar=new ProgressDialog(MainActivity.this);
        bar.setTitle("Connecting server");
        bar.setMessage("Please Wait... ");
        bar.setCancelable(false);
        bar.show();
       if(bar.isShowing()) {
           videoView = findViewById(R.id.v1);
           Uri uri = Uri.parse(path);
           videoView.setVideoURI(uri);
           videoView.start();
           ctlr = new MediaController(this);
           ctlr.setMediaPlayer(videoView);
           videoView.setMediaController(ctlr);
           videoView.requestFocus();
       }
        bar.dismiss();
    }
}

Answer 4

videoView.setURI(Uri.parse(url));// use methods to set url
videoView.start();

然后接受许可

<uses-permission android:name="android.permission.INTERNET"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>

Answer 5

对我来说，将 URL 从

"http://videocdn.bodybuilding.com/video/mp4/62000/62792m.mp4"

至：

"https://videocdn.bodybuilding.com/video/mp4/62000/62792m.mp4"

成功了。

换句话说，我使用了 HTTPS 而不是 HTTP。

我使用以下代码启动视频：

final VideoView videoView = findViewById(R.id.videoview); //id in your xml file
videoView.setVideoURI(Uri.parse(URL)); //the string of the URL mentioned above
videoView.requestFocus();
videoView.start();

public class ShowVideoActivity extends AppCompatActivity {
    private static final String VIDEO_SAMPLE =
            "https://www.youtube.com/watch?v=HexFqifusOk&list=RDHexFqifusOk&start_radio=1";
    private VideoView mVideoView;
    private TextView mBufferingTextView;
    // Current playback position (in milliseconds).
    private int mCurrentPosition = 0;
    // Tag for the instance state bundle.
    private static final String PLAYBACK_TIME = "play_time";

        }

        // Set up the media controller widget and attach it to the video view.
        MediaController controller = new MediaController(this);

        // In Android versions less than N (7.0, API 24), onPause() is the
        // end of the visual lifecycle of the app.  Pausing the video here
        // prevents the sound from continuing to play even after the app
        // disappears.
        //
        // This is not a problem for more recent versions of Android because
        // onStop() is now the end of the visual lifecycle, and that is where
        // most of the app teardown should take place.
        if (Build.VERSION.SDK_INT < Build.VERSION_CODES.N) {

                        // Hide buffering message.
                        mBufferingTextView.setVisibility(VideoView.INVISIBLE);

                        // Restore saved position, if available.
                        if (mCurrentPosition > 0) {
                            mVideoView.seekTo(mCurrentPosition);
                        } else {
