How to play a video that currently focuses on recycler viewing

Question

My application has a video viewer, I want to automatically play back a specific video image that fully focuses when scrolling.

Answer 1

RecyclerView rv_featureList;
private View currentFocusedLayout, oldFocusedLayout;

@Override
public void onCreate(Bundle instanceState) {
    rv_featuredList.addOnScrollListener(new RecyclerView.OnScrollListener() {
        @Override
        public void onScrollStateChanged(RecyclerView recyclerView,
                                         int newState) {
            super.onScrollStateChanged(recyclerView, newState);


            if (newState == AbsListView.OnScrollListener.SCROLL_STATE_IDLE) {
                //get the recyclerview position which is completely visible and first
                int positionView = ((LinearLayoutManager) rv_featuredList.getLayoutManager()).findFirstCompletelyVisibleItemPosition();
                Log.i("VISISBLE", positionView + "");
                if (positionView >= 0) {
                    if (oldFocusedLayout != null) {
                        //Stop the previous video playback after new scroll
                        VideoView vv_dashboard = (VideoView) oldFocusedLayout.findViewById(R.id.vv_dashboard);
                        vv_dashboard.stopPlayback();
                    }


                    currentFocusedLayout = ((LinearLayoutManager) rv_featuredList.getLayoutManager()).findViewByPosition(positionView);
                    VideoView vv_dashboard = (VideoView) currentFocusedLayout.findViewById(R.id.vv_dashboard);
                    //to play video of selected recylerview, videosData is an array-list which is send to recyclerview adapter to fill the view. Here we getting that specific video which is displayed through recyclerview.
                    playVideo(videosData.get(positionView));
                    oldFocusedLayout = currentFocusedLayout;
                }
            }

        }

    });
}
