Question

我使用videoView从Internet播放mp4文件，但是它不能一直播放此视频。这是我的代码：

Uri uri = Uri.parse("http://vfx.mtime.cn/Video/2019/02/08/mp4/190208204943376259.mp4");
videoView.setVideoURI(uri);
videoView.setOnPreparedListener(createOnPreparedListener());

private MediaPlayer.OnPreparedListener createOnPreparedListener(){
        return new MediaPlayer.OnPreparedListener() {
            @Override
            public void onPrepared(MediaPlayer mp) {
                mp.start();
            }
        };
    }

它可以在我的模拟器中很好地运行，但在我的android设备中却无法成功。我的targetSdkVersion和compileSdkVersion是28，我的android设备API是android 28，我的模拟器API是23

Answer 1

全部删除，只需使用

 videoView.setVideoPath(videoUrl);

        videoView.start();

Answer 2

请尝试

 mVideoViewIntro = findViewById(R.id.video_view_intro);
    MediaController mediaController = new MediaController(this);
    mediaController.setAnchorView(mVideoViewIntro);
    mVideoViewIntro.setMediaController(mediaController);
    mVideoViewIntro.setVideoURI(Uri.parse("YOURURLGOESHERE"));
    mVideoViewIntro.start();
    mImageViewClose.setOnClickListener(v -> onBackPressed());

    mVideoViewIntro.setOnPreparedListener(mp -> {
        mp.start();
        mp.setOnVideoSizeChangedListener((mp1, arg1, arg2) -> {
            mProgressBar.setVisibility(View.GONE);
            mp1.start();
        });
    });

Answer 3

我可以通过将其添加到清单清单android：usesCleartextTraffic =“ true”中来解决此问题：

<?xml version="1.0" encoding="utf-8"?>
<manifest ...>
    <uses-permission android:name="android.permission.INTERNET" />
    <application
        ...
        android:usesCleartextTraffic="true"
        ...>
        ...
    </application>
</manifest>
