Android 将 youtube 集成到片段中

Integrating youtube to fragment

提问by Android Developer

My Activity extends another activity and consists of navigation drawer where each item opens a new fragment.I want to integrate Youtube to one of the fragment..Previously i used YouTubePlayerView to integrate Youtube to activity but here it is required in fragment.I searched on net and found YouTubePlayerFragment to integrate youtube to fragment. But when i searched in tutorials I found that even by using YouTubePlayerFragment we are extending YouTubeBaseActivity .These are the examples.. 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

我的活动扩展了另一个活动，并由导航抽屉组成，其中每个项目打开一个新片段。我想将 Youtube 集成到其中一个片段中。以前我使用 YouTubePlayerView 将 Youtube 集成到活动中，但这里需要在片段中进行搜索。我搜索了net 并找到 YouTubePlayerFragment 将 youtube 集成到片段中。但是当我在教程中搜索时，我发现即使使用 YouTubePlayerFragment 我们也在扩展 YouTubeBaseActivity 。这些是示例.. http://android-coding.blogspot.in/2013/04/example-to-use-youtubeplayerfragment-of。 html http://android-er.blogspot.in/2013/06/example-to-use-youtubeplayerfragment-of.html

I failed to understand how to use YouTubePlayerFragment such that my class extends Fragment rather than YouTubeBaseActivity which is required in my project..As u can see below my class extends another activity and consists of navigation drawer in which fifth option opens YouTube Fragment.I want to play Youtube video inside this fragment..I am giving brief layout how my classes are-

我无法理解如何使用 YouTubePlayerFragment 以便我的课程扩展 Fragment 而不是我的项目中所需的 YouTubeBaseActivity ..正如您在下面看到的，我的课程扩展了另一个活动并由导航抽屉组成，其中第五个选项打开 YouTube Fragment。我想要在这个片段中播放 Youtube 视频..我给出了我的课程的简要布局 -

First extend your Activity as normal

首先像往常一样扩展您的活动

 class YourActivity extends Activity...

in Layout file put the below lines

在布局文件中放置以下几行

<fragment
  android:name="com.google.android.youtube.player.YouTubePlayerSupportFragment"
  android:id="@+id/youtube_fragment"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"/>

Then in your Activity you can create its instance using below line in your onCreareView method of your Fragment.

然后在您的 Activity 中，您可以在 Fragment 的 onCreareView 方法中使用以下行创建其实例。

YouTubePlayerSupportFragment youTubePlayerFragment = (YouTubePlayerSupportFragment) getActivity().getSupportFragmentManager()
                    .findFragmentById(R.id.youtube_fragment);

or you can declare a FrameLayout in your xml and then initiate the YouTubeSupportFragmentusing below lines

或者你可以在你的 xml 中声明一个 FrameLayout 然后开始YouTubeSupportFragment使用下面的行

<?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>

Code in your onCreateView

在您的 onCreateView 中编写代码

 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();

The key thing here is to use YouTubePlayerSupportFragmentinstead of YouTubePlayerFragment.

这里的关键是使用YouTubePlayerSupportFragment而不是YouTubePlayerFragment.

Hope this helps.

希望这可以帮助。

Here is your Fragment
