Asking this question because I did not find solution/suggestions after searching for hours. All answered solutions are with Fragment. What I am looking for ViewPagerAdapter and FrameLayout.
My ViewPagerAdapter xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:id="@+id/promotion_layout"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<ImageView
android:id="@+id/some_image"
android:layout_width="match_parent"
android:layout_height="@dimen/view_pager_height"
android:scaleType="fitXY" />
<FrameLayout
android:id="@+id/youtube_fragment"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/>
</LinearLayout>
//Some other view items
</RelativeLayout>
My ViewPagerAdapter Java code:
public class ArticleViewPagerAdapter extends PagerAdapter {
public String TAG = ArticleViewPagerAdapter.class.getSimpleName();
private ArrayList<Article> mArticleList = new ArrayList<>();
private Activity mContext;
private LayoutInflater mLayoutInflater;
private FragmentManager mFragmentManger;
private YouTubePlayerListener mYouTubePlayerListener;
public ArticleViewPagerAdapter(Activity context, ArrayList<Article> articleList, FragmentManager fragmentManager, YouTubePlayerListener youTubePlayerListener) {
this.mContext = context;
this.mArticleList = articleList;
this.mFragmentManger = fragmentManager;
this.mYouTubePlayerListener = youTubePlayerListener;
mLayoutInflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
@Override
public int getCount() {
return mArticleList.size();
}
@Override
public boolean isViewFromObject(@NonNull View view, @NonNull Object object) {
return view == (object);
}
@NonNull
@Override
public Object instantiateItem(@NonNull ViewGroup container, int position) {
View itemView = mLayoutInflater.inflate(R.layout.activity_news, container,
false);
itemView.setTag(position);
updateView(itemView, position);
((ViewPager) container).addView(itemView);
return itemView;
}
@Override
public void destroyItem(ViewGroup container, int position, Object object) {
container.removeView((View) object);
}
private void updateView(View itemView, int position) {
final int index = position;
final View finalView = itemView;
//Initializing the view items
final ImageView mNewsImage = itemView.findViewById(R.id.some_image);
final FrameLayout mYoutubeFragment = itemView.findViewById(R.id.youtube_fragment);
//Let's Test using this
final YouTubePlayerSupportFragment youTubePlayerFragment = YouTubePlayerSupportFragment.newInstance();
ResArticle articleResponse = response.body(); //Got response from API
if (articleResponse != null && articleResponse.getData() != null) {
final Article article = articleResponse.getData();
final String pageUrl = SHARE_BASE_URL + article.getArticleId();
if (article != null) {
if (article.getArticleType()==Constants.ARTICLE_TYPE_NEWS) {
//Basically setting visibility But you can ignore this part
mNewsImage.setVisibility(View.VISIBLE);
mYoutubeFragment.setVisibility(View.GONE);
}
if(article.getArticleType()==Constants.ARTICLE_TYPE_VIDEO) {
Log.d(TAG,"Article Type is Video");
mYoutubeFragment.setVisibility(View.VISIBLE);
mNewsImage.setVisibility(View.GONE);
youTubePlayerFragment.initialize(mContext.getString(R.string.web_client_id), new YouTubePlayer.OnInitializedListener() {
@Override
public void onInitializationSuccess(YouTubePlayer.Provider provider, YouTubePlayer youTubePlayer, boolean wasRestored) {
youTubePlayer.setShowFullscreenButton(false);
youTubePlayer.cueVideo("video_id");
if (mYouTubePlayerListener!=null)
mYouTubePlayerListener.setYouTubePlayer(youTubePlayer);
}
@Override
public void onInitializationFailure(YouTubePlayer.Provider provider, YouTubeInitializationResult youTubeInitializationResult) {
Log.e(TAG, "Youtube Video initialization failed");
}
});
FragmentTransaction transaction = mFragmentManger.beginTransaction();
transaction.replace(R.id.youtube_fragment, youTubePlayerFragment).commit();
}
}
} else {
Toast.makeText(mContext, mContext.getString(R.string.article_info_not_found), Toast.LENGTH_SHORT).show();
Log.e(TAG, "Article info not found");
}
}
}
}
And I am calling the adapter from the Activity NOT the YouTubeBaseActivity.
Problem: YouTube video playback stopped due to unauthorized overlay on top of player. The YouTubePlayerView is not contained inside its ancestor android.widget.FrameLayout The distances between the ancestor's edges and that of the YouTubePlayerView is: left: 0, top: 0, right: 0, bottom: 0 (these should all be positive).
Why I am getting the error? As I am loading Multiple YouTube Player using the ViewPager. As we know the viewpager loads next, previous and current item. So current YouTube video gets initialized and so does the next one. But As current YouTubePlayer overlays the next one(which is pre-loaded).
Please help. Or should I use any library to load YouTube videos.
fix this by removing the padding in the YouTubePlayerView in the layout. So your layout looks like this:
<com.google.android.youtube.player.YouTubePlayerView
android:id="@+id/video_player"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#000" />
why you are using instantiateItem instead of getItem in adapter?
