android – Exoplayer 2可防止视频播放时屏幕变暗

概述我有简单的玩家活动： <?xml version="1.0" encoding="utf-8"?><android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.co 我有简单的玩家活动：

<?xml version="1.0" enCoding="utf-8"?><androID.support.constraint.ConstraintLayout    xmlns:androID="http://schemas.androID.com/apk/res/androID"    xmlns:tools="http://schemas.androID.com/tools"    androID:layout_wIDth="match_parent"    androID:layout_height="match_parent"    tools:context="com.epix.presentation.player.PlayerActivity">    <com.Google.androID.exoplayer2.ui.SimpleExoPlayerVIEw        androID:ID="@+ID/vIDeo_vIEw"        androID:layout_wIDth="match_parent"        androID:layout_height="match_parent" /></androID.support.constraint.ConstraintLayout>

当视频运行时,屏幕会变暗,我必须点击屏幕才能让它再次变亮.我已经尝试设置androID：keepScreenOn =“true”,这当然没有用,因为屏幕没有关闭它只是暗淡.

有没有办法防止屏幕变暗发生？

解决方法 希望这会对某人有所帮助.

在视频播放时设置setKeepScreenOn&仅缓冲,&当视频暂停/未播放/发生任何错误时允许屏幕进入睡眠状态.

playerVIEw = exoPlayerLayout.findVIEwByID(R.ID.exo_player_vIEw);player = ExoPlayerFactory.newSimpleInstance(new DefaultRenderersFactory(context),new DefaultTrackSelector(),new DefaultLoadControl());player.addListener(new PlayerEventListener());

PlayerEventListener

private class PlayerEventListener implements Player.EventListener {    @OverrIDe    public voID onPlayerStateChanged(boolean playWhenReady,int playbackState) {        if (playbackState == Player.STATE_IDLE || playbackState == Player.STATE_ENDED ||                !playWhenReady) {            playerVIEw.setKeepScreenOn(false);        } else { // STATE_IDLE,STATE_ENDED            // This prevents the screen from getting dim/lock            playerVIEw.setKeepScreenOn(true);        }    }    @OverrIDe    public voID onTimelineChanged(Timeline timeline,Object manifest) {}    @OverrIDe    public voID onTracksChanged(TrackGroupArray trackGroups,TrackSelectionArray trackSelections) {}    @OverrIDe    public voID onLoadingChanged(boolean isLoading) {}    @OverrIDe    public voID onRepeatModeChanged(int repeatMode) { }    @OverrIDe    public voID onPlayerError(ExoPlaybackException error) { }    @OverrIDe    public voID onpositiondiscontinuity() { }    @OverrIDe    public voID onPlaybackParametersChanged(PlaybackParameters playbackParameters) { }}

如果要根据需要修改setKeepScreenOn,请检查播放状态here.
