私のアクティビティは別のアクティビティを拡張し、各アイテムが新しいフラグメントを開くナビゲーションドロワーで構成されています.YouTubeをフラグメントの1つに統合したいです。以前はYouTubePlayerViewを使用してYouTubeをアクティビティに統合しましたが、ここではフラグメントで必要です。 netとYouTubePlayerFragmentを見つけて、youtubeをfragmentに統合します。しかし、チュートリアルで検索すると、YouTubePlayerFragmentを使用してもYouTubeBaseActivityを拡張していることがわかりました。これらは例です。 http://Android-coding.blogspot.in/2013/04/example-to-use- youtubeplayerfragment-of.htmlhttp://Android-er.blogspot.in/2013/06/example-to-use-youtubeplayerfragment-of.html
私のクラスがプロジェクトで必要なYouTubeBaseActivityではなくFragmentを拡張するようにYouTubePlayerFragmentを使用する方法を理解できませんでした。このフラグメント内でYoutubeビデオを再生します。クラスの様子を簡単なレイアウトで示しています。

レイアウト
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:Android="http://schemas.Android.com/apk/res/Android"
Android:layout_width="match_parent"
Android:layout_height="match_parent">
<fragment
Android:name="com.google.Android.youtube.player.YouTubePlayerSupportFragment"
Android:id="@+id/youtube_fragment"
Android:layout_width="match_parent"
Android:layout_height="wrap_content"/>
</LinearLayout>
エラー-
Error:(64, 101) error: <anonymous com.pc.gi.ui.fragment.YoutubeFragment$1> is not abstract and does not override abstract method onInitializationFailure(Provider,YouTubeInitializationResult) in OnInitializedListener
最初に通常どおりアクティビティを拡張します
class YourActivity extends Activity...
レイアウトファイルに以下の行を入れて
<fragment
Android:name="com.google.Android.youtube.player.YouTubePlayerSupportFragment"
Android:id="@+id/youtube_fragment"
Android:layout_width="match_parent"
Android:layout_height="wrap_content"/>
次に、アクティビティで、フラグメントのonCreareViewメソッドの以下の行を使用してインスタンスを作成できます。
YouTubePlayerSupportFragment youTubePlayerFragment = (YouTubePlayerSupportFragment) getActivity().getSupportFragmentManager()
.findFragmentById(R.id.youtube_fragment);
または、xmlでFrameLayoutを宣言し、以下の行を使用してYouTubeSupportFragment
を開始できます
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:Android="http://schemas.Android.com/apk/res/Android"
Android:layout_width="match_parent"
Android:layout_height="match_parent" >
<FrameLayout
Android:id="@+id/youtube_fragment"
Android:layout_width="match_parent"
Android:layout_height="match_parent"
Android:layout_centerHorizontal="true"
Android:visibility="visible" />
</RelativeLayout>
OnCreateViewのコード
YouTubePlayerSupportFragment youTubePlayerFragment = YouTubePlayerSupportFragment.newInstance();
youTubePlayerFragment.initialize("DEVELOPER_KEY", new OnInitializedListener() {
@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer player, boolean wasRestored) {
if (!wasRestored) {
YPlayer = player;
YPlayer.setFullscreen(true);
YPlayer.loadVideo("2zNSgSzhBfM");
YPlayer.play();
}
}
@Override
public void onInitializationFailure(Provider arg0, YouTubeInitializationResult arg1) {
// TODO Auto-generated method stub
}
});
FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
transaction.add(R.id.youtube_fragment, youTubePlayerFragment).commit();
ここで重要なことは、YouTubePlayerSupportFragment
の代わりにYouTubePlayerFragment
を使用することです。
