Answer 1

试试这个

 String path="https://www.merastories.com/VideoFiles/a81d1e5c-3e23-418a-9ba8-fca601d1a966-VID_20180322_152225.mp4";
Uri uri=Uri.parse(path1);
VideoView videoview=findViewById(R.id.videoview);
video.setVideoURI(uri);
video.start();

Answer 2

使用ExoPlayer从任何地方显示视频 " 编译 'com.google.android.exoplayer：exoplayer：r2.5.2' ">

使用外线玩家的代码

 if (videoUri != null) {
        shouldAutoPlay = true;
        bandwidthMeter = new DefaultBandwidthMeter();
        mediaDataSourceFactory = new DefaultDataSourceFactory(this, Util.getUserAgent(this, MyApplication.getApplication().getResources().getString(R.string.app_name)), (TransferListener<? super DataSource>) bandwidthMeter);
        window = new Timeline.Window();
        initializePlayer(videoUrl);
    }

  private void initializePlayer(Uri iVideoUri) {
    simpleExoPlayerView = (SimpleExoPlayerView) findViewById(R.id.video_view);
    simpleExoPlayerView.requestFocus();
    TrackSelection.Factory videoTrackSelectionFactory =
            new AdaptiveTrackSelection.Factory(bandwidthMeter);
    trackSelector = new DefaultTrackSelector(videoTrackSelectionFactory);
    player = ExoPlayerFactory.newSimpleInstance(this, trackSelector);
    simpleExoPlayerView.setPlayer(player);
    player.setPlayWhenReady(shouldAutoPlay);
    DefaultExtractorsFactory extractorsFactory = new DefaultExtractorsFactory();
    MediaSource mediaSource = new ExtractorMediaSource(iVideoUri,
            mediaDataSourceFactory, extractorsFactory, null, null);
    player.prepare(mediaSource);
}
private void releasePlayer() {
    if (player != null) {
        shouldAutoPlay = player.getPlayWhenReady();
        player.release();
        player = null;
        trackSelector = null;
    }
