android - Add a full width header item to a Grid View in AbsListView (Xamarin) -


i have list in app, , it's implemented abslistview, when working on smaller screen (phone) it's list , when on larger screen (tablet) it's grid. works well.

now want add in header item different regular items on list - has different xml file. it's first item in list.

i've added in code adapter class so:

    public override view getview(int position, view convertview, viewgroup parent)     {         savedinfo subviews = null;         var rowview = convertview;         var channel = items[position];          // don't want reuse if our previous view header         if (rowview?.tag != null)         {             subviews = rowview.tag savedinfo;         }          // try put in different view if there header shown         // special id value header -1         if (position == 0)         {             subviews = null;         }          if (subviews == null)         {             if (position == 0)             {                 rowview = context.activity.layoutinflater.inflate(resource.layout.header_layout, null);                  // setup stuff layout                 rowview.tag = null;                 return rowview;             }              rowview = context.activity.layoutinflater.inflate(celllayout, null);              // stuff regular layout, take savedinfo tag             rowview.tag = subviews;         }          // other adjustments regular layout          return rowview;     }

so that's fine in regular list - have 1 header item , lots of regular items. however, when switch gridview (which uses same adapter) "header" item first cell in grid.

what want more or less same in list view - single column fills width of screen, followed regular grid. point want item fills columns across, scrolls grid. there way this? understand might need replace sort of custom adapter view. have example of code doing grid 1 item filling multiple grid columns?

thanks

turns out not possible - recommended way put in header use coordinatorlayout , collapsingtoolbarlayout while changing listview recyclerview

Redirect to a HTTPS version using .htaccess -

i need modify .htaccess file redirect urls https version without "www". http://example.com --> https://example.com http://www.example.com --> https://example.com https://www.example.com --> https://example.com this how .htaccess file looks like: rewriteengine on rewritecond %{request_filename} !-d rewritecond %{request_filename} !-f rewriterule ^(.*)$ redirect.php?id=$1&page=$2 [qsa,l] what modifications need make .htaccess in order forward https without "www"? it depends on doing current code. looks file called redirect trying display php page seo friendly url. think might confusing people. anyway, need , force https without www, need 1 more rule above. also second rule needs two capture groups in rewriterule test string because wanting 2 different values using $1 , $2 references. rewriteengine on #rediect www non www and/or http https --- combinations. rewritecond %{http_host} !^example\.com [nc,or] rewritecond %{https} !^
