我试图在片段中实现YouTube播放器。
当我进入屏幕时，我会看到YouTube播放器，但它只是一个黑色背景和一个文字说＆＃34;初始化YouTube播放器时发生错误＆＃34;。
相应的错误堆栈：

在我的片段中我有这个方法来初始化播放器：
private void initYouTubeVideo(final String youTubeVideoId) {
youtubeVideoContainer.setVisibility(View.VISIBLE);
YouTubePlayerSupportFragment youTubePlayerSupportFragment = YouTubePlayerSupportFragment.newInstance();
FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
transaction.replace(R.id.youtube_video_fragment, youTubePlayerSupportFragment).commit();
youTubePlayerSupportFragment.initialize(getResources().getString(R.string.youtube_key),
new YouTubePlayer.OnInitializedListener() {
@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider,
YouTubePlayer youTubePlayer, boolean b) {
YouTubePlayer player;
if (!b) {
player = youTubePlayer;
player.setFullscreen(false);
player.loadVideo(youTubeVideoId);
player.play();
}
}
@Override
public void onInitializationFailure(YouTubePlayer.Provider provider,
YouTubeInitializationResult youTubeInitializationResult) {
// ...
}
});
}
我的xml布局如下所示：
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
android:id="@+id/root_container"
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ScrollView
android:id="@+id/fragment_advice_detail_scrollview"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fillViewport="true">
<LinearLayout
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<!-- Some Views ... -->
<RelativeLayout
android:id="@+id/youtube_video_container"
android:layout_width="match_parent"
android:layout_height="240dp"
android:visibility="gone">
<FrameLayout
android:id="@+id/youtube_video_fragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_centerHorizontal="true"
android:visibility="visible"/>
</RelativeLayout>
<!-- More Views ... -->
</LinearLayout>
</ScrollView>
<FrameLayout
android:id="@+id/progressbar_background"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/progressBackgroundEnabled"
android:clickable="true"
android:visibility="gone">
</FrameLayout>
<ProgressBar
android:id="@+id/progressbar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:indeterminate="true"
android:indeterminateOnly="true"
android:visibility="gone"/>
</FrameLayout>
我知道我的方法到目前为止工作但突然不再起作用了。
当我进入屏幕时，视频会加载很短的时间（几乎不会引人注意），之后会出现这个＆＃34;黑屏并显示错误消息＆＃34;

有时，YouTubePlayerSupportFragment无法正常运行。
请使用WebView在下面的代码中查看。这在我的应用程序中运行良好。
youTubePlayerView = (WebView) view.findViewById(R.id.youtube_view)if (videoUrl != null && !videoUrl.isEmpty()) {
youTubePlayerView.getSettings().setJavaScriptEnabled(true);
youTubePlayerView.getSettings().setPluginState(WebSettings.PluginState.ON);
youTubePlayerView.setWebChromeClient(new WebChromeClient() {
});
final String mimeType = "text/html";
final String encoding = "UTF-8";
String html = getHTML(Utils.getYouTubeVideoId(videoUrl));
youTubePlayerView.loadDataWithBaseURL("", html, mimeType, encoding, "");}
public String getHTML(String videoId) {
String html =
"<iframe class=\"youtube-player\" "
+ "style=\"border: 0; width: 100%; height: 95%;"
+ "padding:0px; margin:0px\" "
+ "id=\"ytplayer\" type=\"text/html\" "
+ "src=\"http://www.youtube.com/embed/" + videoId
+ "?fs=0\" frameborder=\"0\" " + "allowfullscreen autobuffer "
+ "controls onclick=\"this.play()\">\n" + "</iframe>\n";
return html;}
