public class imageadapter extends baseadapter {     private context mcontext;      // constructor     public imageadapter(context c) {         mcontext = c;     }      public int getcount() {         return mthumbids.length;     }      @override     public object getitem(int i) {         return mthumbids[i];     }      @override     public long getitemid(int i) {         return mthumbids[i];     }       @override     public view getview(int position, view convertview, viewgroup parent) {         imageview imageview;      /*if (convertview == null) {*/         imageview = new imageview(mcontext);         imageview.setlayoutparams(new gridview.layoutparams(350, 350));         imageview.setscaletype(imageview.scaletype.fit_start);         imageview.setpadding(8, 8, 8, 8);     /*}     else     {         imageview = (imageview) convertview;     }*/         imageview.setimageresource(mthumbids[position]);         return imageview;     }      // keep images in array     public integer[] mthumbids = {             r.drawable.b1, r.drawable.b2, r.drawable.b3,             r.drawable.b4, r.drawable.b5, r.drawable.b6,             r.drawable.b7, r.drawable.b8, r.drawable.b9,             r.drawable.b10, r.drawable.b11, r.drawable.b12,     }; }
