视频无法播放
我有一个包含Exoplayer的活动。如果我们将视频放在相对布局中，它可以正常工作，但是当我们旋转相对布局时，它不会播放视频，如何做到这一点
这是活动的代码
public class ExoplayerAct extends Activity implements VideoRendererEventListener {
private static final String TAG = "MainActivity";
private SimpleExoPlayerView simpleExoPlayerView;
private SimpleExoPlayer player;
private TextView resolutionTextView;
String j;
RelativeLayout mainlayoutexo;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.exoplayer);
resolutionTextView = new TextView(this);
//resolutionTextView = (TextView) findViewById(R.id.resolution_textView);
Intent iin = getIntent();
Bundle b = iin.getExtras();
if (b != null) {
j = (String) b.get("fileVideoPath");
}
mainlayoutexo = (RelativeLayout) findViewById(R.id.mainlayoutexo);
mainlayoutexo.setRotation(90);
// 1. Create a default TrackSelector
BandwidthMeter bandwidthMeter = new DefaultBandwidthMeter();
TrackSelection.Factory videoTrackSelectionFactory = new AdaptiveTrackSelection.Factory(bandwidthMeter);
TrackSelector trackSelector = new DefaultTrackSelector(videoTrackSelectionFactory);
// 2. Create a default LoadControl
LoadControl loadControl = new DefaultLoadControl();
// 3. Create the player.newSimpleInstance(RenderersFactory, TrackSelector, LoadControl).
player = ExoPlayerFactory.newSimpleInstance(this, trackSelector, loadControl);
simpleExoPlayerView = new SimpleExoPlayerView(this);
simpleExoPlayerView = (SimpleExoPlayerView) findViewById(R.id.player_view);
//Set media controller
simpleExoPlayerView.setUseController(true);
simpleExoPlayerView.requestFocus();
// Bind the player to the view.
simpleExoPlayerView.setPlayer(player);
Uri mp4VideoUri = Uri.parse(j);
//Measures bandwidth during playback. Can be null if not required.
DefaultBandwidthMeter bandwidthMeterA = new DefaultBandwidthMeter();
//Produces DataSource instances through which media data is loaded.
DefaultDataSourceFactory dataSourceFactory = new DefaultDataSourceFactory(this
, Util.getUserAgent(this, "exoplayer2example"), bandwidthMeterA);
//Produces Extractor instances for parsing the media data.
ExtractorsFactory extractorsFactory = new DefaultExtractorsFactory();
// II. ADJUST HERE:
//This is the MediaSource representing the media to be played:
//FOR SD CARD SOURCE:
MediaSource videoSource = new ExtractorMediaSource(mp4VideoUri, dataSourceFactory, extractorsFactory, null, null);
//FOR LIVESTREAM LINK:
// MediaSource videoSource = new HlsMediaSource(mp4VideoUri, dataSourceFactory, 1, null, null);
final LoopingMediaSource loopingSource = new LoopingMediaSource(videoSource);
// Prepare the player with the source.
player.prepare(loopingSource);
player.addListener(new ExoPlayer.EventListener() {
@Override
public void onTimelineChanged(Timeline timeline, Object manifest) {
Log.v(TAG, "Listener-onTimelineChanged...");
}
@Override
public void onTracksChanged(TrackGroupArray trackGroups, TrackSelectionArray trackSelections) {

Log.v(TAG, "Listener-onLoadingChanged...isLoading:"+isLoading);
}
@Override
public void onPlayerStateChanged(boolean playWhenReady, int playbackState) {
Log.v(TAG, "Listener-onPlayerStateChanged..." + playbackState);
}
@Override
public void onRepeatModeChanged(int repeatMode) {
Log.v(TAG, "Listener-onRepeatModeChanged...");
}
@Override
public void onPlayerError(ExoPlaybackException error) {
Log.v(TAG, "Listener-onPlayerError...");
player.stop();
player.prepare(loopingSource);
player.setPlayWhenReady(true);
}
@Override
public void onPositionDiscontinuity() {
Log.v(TAG, "Listener-onPositionDiscontinuity...");
}
@Override
public void onPlaybackParametersChanged(PlaybackParameters playbackParameters) {
Log.v(TAG, "Listener-onPlaybackParametersChanged...");
}
});
PlaybackParameters playbackParameters = new PlaybackParameters(2.0f, 1.0f);
player.setPlaybackParameters(playbackParameters);
player.setPlayWhenReady(true); //run file/link when ready to play.
player.setVideoDebugListener(this); //for listening to resolution change and outputing the resolution
}//End of onCreate
@Override
public void onVideoEnabled(DecoderCounters counters) {
}
@Override
public void onVideoDecoderInitialized(String decoderName, long initializedTimestampMs, long initializationDurationMs) {
}
@Override
public void onVideoInputFormatChanged(Format format) {
}
@Override
public void onDroppedFrames(int count, long elapsedMs) {
}
@Override
public void onVideoSizeChanged(int width, int height, int unappliedRotationDegrees, float pixelWidthHeightRatio) {
Log.v(TAG, "onVideoSizeChanged [" + " width: " + width + " height: " + height + "]");
resolutionTextView.setText("RES:(WxH):"+width+"X"+height +"\n "+height+"p");
}
@Override
public void onRenderedFirstFrame(Surface surface) {
}
@Override
public void onVideoDisabled(DecoderCounters counters) {
}
//-------------------------------------------------------ANDROID LIFECYCLE---------------------------------------------------------------------------------------------
@Override

super.onStop();
Log.v(TAG, "onStop()...");
}
@Override

}

}
}
，布局是
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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"

</RelativeLayout>
我只想旋转包含exoplayer的相对布局，如何做到这一点并用它进行视频播放
答案 0 :(得分：0)
我正在运行相同的代码，虽然旋转dosnt有任何处理，但是当我在纵向和横向之间切换时，视频仍会运行。它暂停一秒，然后继续新的方向。
我在日志中收到警告，但这是关于预期的。
你可以发布你得到的日志吗？
