android - 将 youtube 集成到 fragment

标签 android android-fragments youtube fragment

我的 Activity 扩展了另一个 Activity 并由抽屉导航组成，其中每个项目打开一个新 fragment 。我想将 Youtube 集成到其中一个 fragment 中。以前我使用 YouTubePlayerView 将 Youtube 集成到 Activity 但这里在 fragment 中是必需的。我在网上搜索，发现 YouTubePlayerFragment 将 youtube 集成到 fragment 。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

我无法理解如何使用 YouTubePlayerFragment 以使我的类扩展 Fragment 而不是我的项目中所需的 YouTubeBaseActivity..正如您在下面看到的那样，我的类扩展了另一个 Activity 并包含抽屉导航，其中第五个选项打开 YouTube Fragment .我想在这个 fragment 中播放 Youtube 视频..我正在简要布局我的类(class)如何-

public class LandingActivity extends BaseGActivity {
.
.

public void selectDrawerItem(int position) {

        Bundle args = new Bundle();

        switch (position) {
            case 0:
                currentFragment = new HomeFragment_();
                args.putString(G.General.MEDIA_TYPE_KEY, G.General.MEDIA_TYPE_ALL);
                GApplication.getInstance().stopGPlayer();
                break;
            case 1:
                currentFragment = new HomeFragment_();
                args.putString(G.General.MEDIA_TYPE_KEY, G.General.MEDIA_TYPE_PHOTO);
                GApplication.getInstance().stopGPlayer();
                break;
//
            case 2:

                GApplication.getInstance().stopGPlayer();
                break;

            case 3:
                currentFragment = new HomeFragment_();
                args.putString(G.General.MEDIA_TYPE_KEY, G.General.MEDIA_TYPE_VIDEO);
                GApplication.getInstance().stopGPlayer();
                break;
            case 4:
                currentFragment = new HomeFragment_();
                args.putString(G.General.MEDIA_TYPE_KEY, G.General.MEDIA_TYPE_MEME);
                GApplication.getInstance().stopGPlayer();
                break;
            case 5:
                currentFragment = new YoutubeFragment();
            default:
                currentFragment = new HomeFragment_();
                args.putString(G.General.MEDIA_TYPE_KEY, G.General.MEDIA_TYPE_ALL);
                GApplication.getInstance().stopGPlayer();
                break;
        }

        currentFragment.setArguments(args);
        FragmentManager frgManager = getFragmentManager();
        frgManager.beginTransaction().replace(R.id.content_frame, currentFragment)
                .commit();

        mDrawerList.setItemChecked(position, true);
        setTitle(dataList.get(position).getItemName());
        mDrawerLayout.closeDrawers();

        @Override
        public void onInitializationFailure(YouTubePlayer.Provider provider,

    }

YouTubeFragment.java

public class YoutubeFragment extends Fragment implements
        YouTubePlayer.OnInitializedListener {
    private FragmentActivity myContext;

private YouTubePlayer YPlayer;
private static final String YoutubeDeveloperKey = "xyz";
private static final int RECOVERY_DIALOG_REQUEST = 1;

@Override
public void onAttach(Activity activity) {

    if (activity instanceof FragmentActivity) {
        myContext = (FragmentActivity) activity;
    }

    super.onAttach(activity);
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

    View rootView = inflater.inflate(R.layout.activity_you_tube_api, container, false);

    YouTubePlayerSupportFragment youTubePlayerFragment = YouTubePlayerSupportFragment.newInstance();

    youTubePlayerFragment.initialize("DEVELOPER_KEY", new YouTubePlayer.OnInitializedListener() {


    });
    FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
    transaction.add(R.id.youtube_fragment, youTubePlayerFragment).commit();
    return rootView;

}
    @Override
    public void onInitializationSuccess (YouTubePlayer.Provider provider, YouTubePlayer
    youTubePlayer,boolean b){
        if (!b) {
            YPlayer = youTubePlayer;
            YPlayer.setFullscreen(true);
            YPlayer.loadVideo("2zNSgSzhBfM");
            YPlayer.play();
        }
    }

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

    }
}

布局

 <?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>

错误-

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

最佳答案

首先正常扩展您的 Activity 

 class YourActivity extends Activity...

在布局文件中放入以下行

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

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

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

或者您可以在您的 xml 中声明一个 FrameLayout，然后使用以下行启动 YouTubeSupportFragment

<?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 中的代码

 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();

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

希望这会有所帮助。

这是你的 fragment 

import android.app.Activity;
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentTransaction;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import com.google.android.youtube.player.YouTubeInitializationResult;
import com.google.android.youtube.player.YouTubePlayer;
import com.google.android.youtube.player.YouTubePlayer.OnInitializedListener;
import com.google.android.youtube.player.YouTubePlayer.Provider;
import com.google.android.youtube.player.YouTubePlayerSupportFragment;
import com.ismart.omanapp.R;

public class YoutubeFragment extends Fragment {
    private FragmentActivity myContext;

    private YouTubePlayer YPlayer;
    private static final String YoutubeDeveloperKey = "xyz";
    private static final int RECOVERY_DIALOG_REQUEST = 1;

    @Override
    public void onAttach(Activity activity) {

        if (activity instanceof FragmentActivity) {
            myContext = (FragmentActivity) activity;
        }

        super.onAttach(activity);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        View rootView = inflater.inflate(R.layout.activity_you_tube_api, container, false);

        YouTubePlayerSupportFragment youTubePlayerFragment = YouTubePlayerSupportFragment.newInstance();
        FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
        transaction.add(R.id.youtube_fragment, youTubePlayerFragment).commit();

        youTubePlayerFragment.initialize("DEVELOPER_KEY", new OnInitializedListener() {

            @Override
            public void onInitializationSuccess(Provider arg0, YouTubePlayer youTubePlayer, boolean b) {
                if (!b) {
                    YPlayer = youTubePlayer;
                    YPlayer.setFullscreen(true);
                    YPlayer.loadVideo("2zNSgSzhBfM");
                    YPlayer.play();
                }
            }

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

            }
        });

    }
}
