Android Youtube api View Pager问题

Question

我正在使用viewpager来加载youtube视频，它使用FragmentPagerAdapter来提供Youtube片段到viewpager。我遇到的问题是，第一个youtube视频被加载了，而其他的没有。

下面是在我的HomeFragment中创建viewpager的方法

public void setupUI(View view)
{
   // viewPager = (ViewPager) findViewById(R.id.pager);
    viewpager = (ViewPager) view.findViewById(R.id.pager);
    pager_adapter = new ViewPagerAdapter(getActivity(),rank,country,population,flag);
    FragmentActivity fragact = myContext;



    FragmentPagerAdapter fragmentAdapter = new FragmentAdapter(fragact.getSupportFragmentManager());
    viewpager.setAdapter(fragmentAdapter);

    //pager_adapter = new ViewPagerAdapter(MainActivity.this, rank, country, population, flag);
    // Binds the Adapter to the ViewPager
    //viewPager.setAdapter(adapter);

    CirclePageIndicator titleIndicator = (CirclePageIndicator)view.findViewById(R.id.indicator);
    titleIndicator.setViewPager(viewpager);
}

下面是我的片段适配器

public class FragmentAdapter extends FragmentPagerAdapter{

public FragmentAdapter(FragmentManager fragmentManager) {

    super(fragmentManager);
}
@Override
public Fragment getItem(int position) {
    String test = Integer.toString(position);
    ImageFragment imgfrag = ImageFragment.newInstance(test,test);
    return imgfrag;
}

@Override
public int getCount() {
    return FRAGMENT_COUNT;
}

以下是加载youtube视频的片段

public class ImageFragment extends Fragment implements YouTubePlayer.OnInitializedListener {
// TODO: Rename parameter arguments, choose names that match
// the fragment initialization parameters, e.g. ARG_ITEM_NUMBER
private static final String ARG_PARAM1 = "param1";
private static final String ARG_PARAM2 = "param2";
private YouTubePlayer activePlayer;
public static final String YOUTUBE_API_KEY = "xxxxxxxxxxxxxxxxxxx";



// TODO: Rename and change types of parameters
private String mParam1;


private OnFragmentInteractionListener mListener;

/**
 * Use this factory method to create a new instance of
 * this fragment using the provided parameters.
 *
 * @param param1 Parameter 1.
 * @param param2 Parameter 2.
 * @return A new instance of fragment ImageFragment.
 */
// TODO: Rename and change types and number of parameters
public static ImageFragment newInstance(String param1, String param2) {
    ImageFragment fragment = new ImageFragment();
    Bundle args = new Bundle();
    args.putString(ARG_PARAM1, param1);
    fragment.setArguments(args);
    return fragment;
}



public ImageFragment() {
    // Required empty public constructor
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    if (getArguments() != null) {
        mParam1 = getArguments().getString(ARG_PARAM1);

    }
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View RootView = inflater.inflate(R.layout.fragment_image, container, false);
    YouTubePlayerSupportFragment youTubePlayerFragment = new YouTubePlayerSupportFragment();
    youTubePlayerFragment.initialize(YOUTUBE_API_KEY,this);
    //FragmentTransaction transaction = getFragmentManager().beginTransaction();
    //android.support.v4.app.FragmentManager fragmentManager = getActivity().getSupportFragmentManager();
    android.support.v4.app.FragmentTransaction fragmentTransaction = getActivity().getSupportFragmentManager().beginTransaction();
    fragmentTransaction.replace(R.id.youtubeplayerfragment,youTubePlayerFragment,YouTubePlayerFragment.class.getSimpleName());
    fragmentTransaction.commit();
    RootView.findViewById(R.id.youtubeplayerfragment).setVisibility(View.VISIBLE);
    return RootView;
}

// TODO: Rename method, update argument and hook method into UI event
public void onButtonPressed(Uri uri) {
    if (mListener != null) {
        mListener.onFragmentInteraction(uri);
    }
}

@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean b) {

        youTubePlayer.cueVideo("nCgQDjiotG0");
    Log.v("Youtube", "Success occured one");


}

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

    String errorMessage = String.format("error reason", youTubeInitializationResult.toString());
    Toast.makeText(getActivity(), errorMessage, Toast.LENGTH_SHORT).show();
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == 1) {
        // Retry initialization if user performed a recovery action
        getYouTubePlayerProvider().initialize(YOUTUBE_API_KEY, this);
    }
}

protected YouTubePlayer.Provider getYouTubePlayerProvider() {
    return (YouTubePlayerSupportFragment) getFragmentManager().findFragmentByTag(YouTubePlayerFragment.class.getSimpleName());
}


/**

public interface OnFragmentInteractionListener {
    // TODO: Update argument type and name
    public void onFragmentInteraction(Uri uri);
}

//我认为在暂停时释放片段是您缺少的东西

@Override public void onPause() {

    super.onPause();
    if (youTubePlayerFragment != null) {
        getChildFragmentManager().beginTransaction()
                .remove(getChildFragmentManager().findFragmentById(R.id.yourcontainerid))
                .commit();

    }
    Player.release();
}
