我在制作CHROMELESS youtube播放器视图时创建的内容在这里。它加载和播放都很完美，但即使视频完成，缓冲圈也会持续播放。有人能帮助我在不需要的时候删除缓冲进度，并制作一个完美的youtube播放器吗？

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
context = this;
playerStateChangeListener = new MyPlayerStateChangeListener();
playbackEventListener = new MyPlaybackEventListener();
YOUTUBE_API_KEY = "PLACE_YOUR_API_KEY_HERE";
youTubeView = (YouTubePlayerView) findViewById(R.id.youtube_view);
youTubeView.initialize(YOUTUBE_API_KEY, this);
}
@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, final YouTubePlayer player, boolean wasRestored) {
player.setPlayerStateChangeListener(playerStateChangeListener);
player.setPlaybackEventListener(playbackEventListener);
if (!wasRestored) {
player.loadVideo("fhWaJi1Hsfo"); // Plays https://www.youtube.com/watch?v=fhWaJi1Hsfo
player.setPlayerStyle(YouTubePlayer.PlayerStyle.CHROMELESS);
}
}
@Override
public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult errorReason) {
if (errorReason.isUserRecoverableError()) {
Toast.makeText(context, errorReason.toString(), Toast.LENGTH_LONG).show();
// errorReason.getErrorDialog(this, RECOVERY_REQUEST).show();
} else {
String error = errorReason.toString();
Toast.makeText(context, error, Toast.LENGTH_LONG).show();
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == RECOVERY_REQUEST) {
// Retry initialization if user performed a recovery action
getYouTubePlayerProvider().initialize(YOUTUBE_API_KEY, this);
}
}
private void showMessage(String message) {
Toast.makeText(this, message, Toast.LENGTH_LONG).show();
}

return youTubeView;
}
private final class MyPlaybackEventListener implements YouTubePlayer.PlaybackEventListener {
@Override

showMessage("Playing");
}

showMessage("Paused");
}
@Override
public void onStopped() {
// Called when playback stops for a reason other than being paused.
showMessage("Stopped");
}
@Override

// due to user scrubbing or call to seekRelativeMillis() or seekToMillis()

}

activity_main.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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"

</RelativeLayout>
在onInitializationSuccess()中，在播放器上设置一个PlaybackEventListener。覆盖onBuffering()并执行以下操作：
ViewGroup ytView = youTubeView; // if you are using YouTubePlayerView
ViewGroup ytView = (ViewGroup)ytPlayerFragment.getView(); // if you are using YouTubePlayerFragment
ProgressBar progressBar;
try {
// As of 2016-02-16, the ProgressBar is at position 0 -> 3 -> 2 in the view tree of the Youtube Player Fragment/View
ViewGroup child1 = (ViewGroup)ytView.getChildAt(0);
ViewGroup child2 = (ViewGroup)child1.getChildAt(3);
progressBar = (ProgressBar)child2.getChildAt(2);
} catch (Throwable t) {
// As its position may change, we fallback to looking for it
progressBar = findProgressBar(ytView);
// I recommend reporting this problem so that you can update the code in the try branch: direct access is more efficient than searching for it
}
int visibility = isBuffering ? View.VISIBLE : View.INVISIBLE;
if (progressBar != null) {
progressBar.setVisibility(visibility);
// Note that you could store the ProgressBar instance somewhere from here, and use that later instead of accessing it again.
}
制作方法如下：
private ProgressBar findProgressBar(View view) {
if (view instanceof ProgressBar) {
return (ProgressBar)view;
} else if (view instanceof ViewGroup) {
ViewGroup viewGroup = (ViewGroup)view;
for (int i = 0; i < viewGroup.getChildCount(); i++) {
ProgressBar res = findProgressBar(viewGroup.getChildAt(i));
if (res != null) return res;
}
}
return null
}
通过这种方式，您可以在缓冲时启用进度，而在不缓冲时禁用进度。
