基于google ExoPlayer 简单自定义播放界面

 1. 基于google ExoPlayer播放m3u8，mp4等文件  

简单自定义播放界面，新建一个Layout

布局文件命名为exo_playback_control_view，控件的id不能随便起，

要与exoPlayer原来PlaybackControlView的布局控件id，名称一致，

布局名称不一定是exo_playback_control_view，不过需要在SimpleExoPlayerView控件中添加一个：

app:controller_layout_id="@layout/id" ，指定control的布局；如：

  2.如果需要详细的自定义播放界面，需要重写SimpleExoPlayerView，和PlaybackControlView。  3.重要的类

/**
* 监听播放状态
*/

private final class ComponentListener implements ExoPlayer.EventListener {

@Override
public void onPlayerStateChanged(boolean playWhenReady, int playbackState) {

switch (playbackState) {
/**
* The player is able to immediately
/*play from its current position. The player will be playing if
* {@link #getPlayWhenReady()} is true, and paused otherwise.
*/

case Player.STATE_READY://
showLoading(false);
play(playWhenReady);
break;
/**
* The player has finished playing the media.
*/
case Player.STATE_ENDED:
showLoading(false);
playDefault();
break;
/**
* The player does not have any media to play.
*/
case Player.STATE_IDLE:
showLoading(true);
break;
/**
* The player is not able to
/*immediately play from its current position. This state typically
* occurs when more data needs to be loaded.
*/
case Player.STATE_BUFFERING:
showLoading(true);
break;
}
}

@Override
public void onRepeatModeChanged(int repeatMode) {
// Do nothing.
}

@Override
public void onPositionDiscontinuity() {
// Do nothing.
}

@Override
public void onPlaybackParametersChanged(PlaybackParameters playbackParameters) {
// Do nothing.
}

@Override
public void onTimelineChanged(Timeline timeline, Object manifest) {
// Do nothing.
}

@Override
public void onTracksChanged(TrackGroupArray trackGroups, TrackSelectionArray trackSelections) {
// Do nothing.
}

@Override
public void onLoadingChanged(boolean isLoading) {
// Do nothing.
}

@Override
public void onPlayerError(ExoPlaybackException error) {
// Do nothing.
}

}

  4.重要的方法：

/**
* 根据不同的Uri文件，生成不同的MediaSource
*
* @param uri
* @param overrideExtension
* @return
*/

private MediaSource buildMediaSource(Uri uri, String overrideExtension) {
int type = Util.inferContentType(!TextUtils.isEmpty(overrideExtension) ?
"." + overrideExtension
: uri.getLastPathSegment());
switch (type) {
case C.TYPE_SS:
return new SsMediaSource(uri, buildDataSourceFactory(false),
new DefaultSsChunkSource.Factory(mediaDataSourceFactory), null, null);
case C.TYPE_DASH:
return new DashMediaSource(uri, buildDataSourceFactory(false),
new DefaultDashChunkSource.Factory(mediaDataSourceFactory), null, null);
case C.TYPE_HLS:
return new HlsMediaSource(uri, mediaDataSourceFactory, null, null);
case C.TYPE_OTHER:
return new ExtractorMediaSource(uri, mediaDataSourceFactory, new DefaultExtractorsFactory(),
null, null);
default: {
throw new IllegalStateException("Unsupported type: " + type);
}
}
}
