Implementing Android (no 3rd party) Listview Subheaders

is there any possibility to implement the subheader behaviour as suggested by the google guidelines (see: https://www.google.com/design/spec/components/subheaders.html)? Especially the sticky functionality of the headers is important for me.

I found different libraries on github (e.g. https://github.com/emilsjolander/StickyListHeaders), but i wonder if there is a direct support in the android sdk.

Thanks

If you don't want them sticky, and exactly know what positions the headers are going to be( in your data array), then you could simply use following trick :

header is just another list item type,

so extend BaseAdapter and override following methods : 

@Override
getViewTypeCount(){
    return 2;// 1(list items) + 1(for header)
}

@Override
getItemViewType(int position){
if(want to show header at position)
    return 1; // header item
else
    return 0;// regular items
}

@Override
getView(int pos,....)
{
    if(getItemViewType(pos)==0){// regular item
        inflate/reuse convertView; // cast to regular item & bind data
    } else {
        inflate/reuse convertView; // cast to hdr view and bind data 
    }
    return convertView;
}
