java - select one column of GridView -

i have gridview 2 columns, arraylist fill out gridview. customadapter handle data between gridview , arraylist. gridview choicemode single in gridview xml file,and can select left column , right column both. want select left column , not right.

here gridview design xml :

<gridview         android:layout_width="fill_parent"         android:layout_height="330dp"         android:layout_margintop="15dp"         android:id="@+id/gridview"         android:numcolumns="2"         android:layoutdirection="rtl"         android:foregroundgravity="center_horizontal"         android:gravity="right"         android:textdirection="locale"         android:background="#e6b800"         android:choicemode="singlechoice"         android:layout_below="@+id/textview3"         android:layout_alignparentleft="true"         android:layout_alignparentstart="true"         /> 

and here customadapter class :

 public class customadapter<string> extends arrayadapter<string> {     context contex;     int id;     arraylist<string> arraylist;        public customadapter(context contex, int layoutid, arraylist<string> arraylist)     {         super(contex, id, arraylist);         this.contex = contex;         this.layoutid = id;         this.arraylist = arraylist;     }      @override     public boolean areallitemsenabled() {         return false;     }      @override     public boolean isenabled(int position) {         return true;     }      @override     public view getview(int position, view convertview, viewgroup parent) {         return super.getview(position, convertview, parent);     }  } 

and here usage of customadapter in class :

customadapter =  new customadapter<string>(getapplicationcontext(), android.r.layout.select_dialog_singlechoice, mylist); 

and here how fill out arraylist :

   mylist.add(drivername);    mylist.add(platenumber);    customadapter.getitemviewtype(r.id.gridview);    myadapter.isenabled(myadapter.getposition(platenumber));    mygridview.setadapter(customadapter); 

drivername , platenumber string added listview

and after data entered list( after while loop ) added code prevent select both column, doesnt work :

customadapter.areallitemsenabled(); customadapter.isenabled(customadapter.getposition(platenumber)); 

again, changed solution. used 2 listview instead of 1 gridview 2 rows. , sync movement. if google, find out how sync 2 listview movement.
