Android版YouTube API取得查看传呼机问题 [英] Android Youtube api View Pager issue
本文介绍了Android版YouTube API取得查看传呼机问题的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我使用的是viewpager加载YouTube视频使用它来FragmentPagerAdapter饲料的Youtube片段的viewpager。我遇到的问题是，第一个YouTube视频负载，剩下的一点儿也不。
I am using a viewpager to load youtube videos which using FragmentPagerAdapter to feed Youtube fragment to the viewpager. The problem i am having is that the first youtube video loads and the rest does'nt.
下面是我HomeFragment创建该viewpager方法
Here is the method in my HomeFragment that creates the viewpager
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;
}
下面是加载YouTube视频
Here's the fragment that loads youtube video
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());
}
/**

* fragment to allow an interaction in this fragment to be communicated
* to the activity and potentially other fragments contained in that
* activity.

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

帮助将是非常美联社preciated。
在此先感谢
Help would be really appreciated. Thanks in advance
推荐答案
//我觉得释放在暂停的片段是你缺少的东西。
//I think releasing the fragment in on Pause is the thing you are missing
@覆盖
公共无效的onPause（）{
@Override public void onPause() {
super.onPause();
if (youTubePlayerFragment != null) {
getChildFragmentManager().beginTransaction()
.remove(getChildFragmentManager().findFragmentById(R.id.yourcontainerid))
.commit();
}
Player.release();
}
