Automatically Playing video in listview/scrollview similar to facebook

问题

I need Video to play automatically in listview/scrollview, if view contains video. This is ver much similar with facebook. If user scrolls down and visible area contains video that system will play video and if still scroll then it automaticaly stops that video. It should work like one video should play at one time.

Can someone help me on this ?

Please follow the points

First you need to add a scroll listener into RecyclerView

Then through the listener update your RecyclerView adapter

protected void onListViewUpdate(final int position, final Object object) {
    final RecyclerView view = mView;
    LinearLayoutManager layoutManager = ((LinearLayoutManager)view.getLayoutManager());
    final View convertView = layoutManager.findViewByPosition(position);
    int firstVisiblePosition = layoutManager.findFirstCompletelyVisibleItemPosition();
    int lastVisiblePosition = layoutManager.findLastCompletelyVisibleItemPosition();            

    if (firstVisiblePosition <= position && position <= lastVisiblePosition) {
        // this is the convertView that you previously returned in getView
        // just fix it (for example:)

        Thread thread = new Thread(){
            @Override
            public void run() {
                super.run();

                runOnUiThread(new Runnable() {
                    @Override
                    public void run() {
                        adapter.updateRow(adapter.getItem(position), convertView, object);
                    }
                });
            }
        };
        thread.start();
    } else {
        // just update your data set, UI will be updated automatically in next
        // getView() call
        adapter.updateData(position, object);
    }
}

From the adapter update the current visible view from updateRow() method.

Job Done :)
