I didn't use a real device, I was working on emulator. (Problem Solved)

我正在开发一个直播视频应用程序。我有很多带有 *.m3u8 后缀的直播 URL。

当我启动应用程序时，我只能听到声音，但没有视频显示。视频显示区域总是很暗。

我正在等待您的有用建议来解决我的问题。

问候。

我的一些代码：

public class MainActivity extends Activity {

    private static ProgressDialog progressDialog;

    String videourl = "URL/playlist.m3u8";
    VideoView videoView;

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

        videoView = (VideoView) findViewById(R.id.video_View);

        progressDialog = ProgressDialog.show(MainActivity.this, "", "Buffering video...", true);
        progressDialog.setCancelable(false);

        PlayVideo();
    }

    private void PlayVideo() {
        try {
            getWindow().setFormat(PixelFormat.TRANSLUCENT);

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

            Uri video = Uri.parse(videourl);
            videoView.setMediaController(mediaController);
            videoView.setVideoURI(video);
            videoView.requestFocus();
            videoView.setVisibility(View.VISIBLE);

            videoView.setOnPreparedListener(new OnPreparedListener() {

                public void onPrepared(MediaPlayer mp) {
                    progressDialog.dismiss();
                    videoView.start();

                }
            });

        } catch (Exception e) {
            progressDialog.dismiss();
            System.out.println("Video Play Error :" + e.toString());
            finish();
        }

    }

}

布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >



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


</LinearLayout>
