java - fragment 中的 YouTubePlayerSupportFragment

Question

我有一个 MenuActivity，在 MenuActivity 中我有一个 SeguridadMenuFrament，在 SeguridadMenuFrament 中我有 SeguridadFragment。在 SeguridadFrament 中，我需要实现 YoutubePlayer。

在我的fragment_seguridad.xml

    <?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <TextView
    android:id="@+id/tvTitle"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="@string/TR_CARACTERISTICAS"
    android:textSize="@dimen/text_14"
    android:layout_marginTop="20dp"/>

    <TextView
    android:id="@+id/tvCaracteristicas"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:textSize="@dimen/text_12"
        app:layout_constraintTop_toBottomOf="@id/tvTitle"
    android:layout_marginTop="20dp"/>

    <fragment
        android:name="com.google.android.youtube.player.YouTubePlayerSupportFragment"
        android:id="@+id/youtubePF"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_marginTop="20dp"
        app:layout_constraintTop_toBottomOf="@id/tvCaracteristicas"/>


</android.support.constraint.ConstraintLayout>

在 SeguridadFragment.java 中

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    rootView = inflater.inflate(R.layout.fragment_seguridad, container, false);

    mYoutubePlayerFragment = new YouTubePlayerSupportFragment();
    mYoutubePlayerFragment.initialize(YoutubeDeveloperKey, new YouTubePlayer.OnInitializedListener() {
        @Override
        public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {
            if (!b) {
                youTubePlayer.cueVideo("NMwE93GQcKs");
            }
        }

        @Override
        public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {

        }
    });

    FragmentManager fragmentManager = getFragmentManager();
    FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
    fragmentTransaction.replace(R.id.youtubePF, mYoutubePlayerFragment);
    fragmentTransaction.commit();

    return rootView;
}

但是当运行应用程序并显示 fragment 时，应用程序崩溃并显示:

您需要在布局中使用 FrameLayout 而不是 Fragment

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <TextView
        android:id="@+id/tvTitle"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="@string/TR_CARACTERISTICAS"
        android:layout_marginStart="20dp"
        android:layout_marginLeft="20dp"
        android:layout_marginEnd="20dp"
        android:layout_marginRight="20dp"
        android:layout_marginTop="20dp"/>

    <TextView
    android:id="@+id/tvCaracteristicas"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:textSize="@dimen/text_12"
        app:layout_constraintTop_toBottomOf="@id/tvTitle"
    android:layout_marginTop="20dp"/>

    <FrameLayout
        android:id="@+id/frame_fragment"
        android:layout_width="match_parent"
        android:layout_height="200dp"/>

</LinearLayout>

然后在您的 Fragment 类中使用此代码:

YouTubePlayerSupportFragment youTubePlayerFragment = YouTubePlayerSupportFragment.newInstance();

        FragmentTransaction transaction = getFragmentManager().beginTransaction();
        transaction.replace(R.id.frame_fragment, youTubePlayerFragment);
        transaction.commit();

        youTubePlayerFragment.initialize(YoutubeDeveloperKey, new YouTubePlayer.OnInitializedListener() {

            @Override
            public void onInitializationSuccess(YouTubePlayer.Provider arg0, YouTubePlayer youTubePlayer, boolean b) {
                if (!b) {
                    YPlayer = youTubePlayer;
                    YPlayer.setFullscreen(false);
                    YPlayer.loadVideo("NMwE93GQcKs");
                    YPlayer.play();
                }
            }

            @Override
            public void onInitializationFailure(YouTubePlayer.Provider arg0, YouTubeInitializationResult arg1) {
                // TODO Auto-generated method stub

            }
        });

希望对您有所帮助!
