override getItemViewType(int position) and getViewTypeCount() method in your adapter and inflate you view according to it from getView(). In you case write methods like

 @Override
public int getItemViewType(int position) {
        if(list.get(position).flag == text)
            return 0;
         else if(list.get(position).flag == image) 
            return 1;
         else
            return 2;         
}

@Override
public int getViewTypeCount() {
    return 3;
}

I am not pretty much sure but it's my concept that firstly create a layout for row that can hold every thing that you want show(image, video, text etc ). And make this layout such a way if one thing is not present then it automatically wrapped(means if video is not present then video space will not be there). Now make json of every list row and pass it to Adapter of list. Then override getView() method of the
adapter and parse json there and display according to your layout.
