if need more information feel free ask.

thanks in advance.

your problem here:

convertview = inflater.inflate(r.layout.messagelistrow, null); 

you not initialize inflater in code

you need:

 inflater = (layoutinflater) context                 .getsystemservice(context.layout_inflater_service); 

in getview method, getview method must be:

@override      public view getview(int position, view convertview, viewgroup parent) {           viewholder holder;             if(convertview==null)             {                 inflater = (layoutinflater) context                 .getsystemservice(context.layout_inflater_service);                  holder = new viewholder();                 convertview = inflater.inflate(r.layout.messagelistrow, null);                  holder.icon = (imageview) convertview.findviewbyid(r.id.icon);                 holder.messagesnippet = (textview) convertview.findviewbyid(r.id.messagesnippet);                 holder.messagedate = (textview) convertview.findviewbyid(r.id.messagedate);                  convertview.settag(holder);             }             else                 holder=(viewholder)convertview.gettag();              messagelistitem ml = (messagelistitem) rowitems.get(position);              holder.icon.setimageresource(ml.geticonid());             holder.messagesnippet.settext(ml.getmessagesnippet());             holder.messagedate.settext(ml.getmessagedate());              return convertview;         } 

another problem in history xml file: line 8

binary xml file line #8: error inflating class fragment 

you need change fragment framelayout
