android - Custom ViewGroup, GridView, and SimpleCursorAdapter -

i need display data in 3 textviews, inside each grid item, want each grid item square. cursoradapter based on search.

based on necessities found research should creating own viewgroup each grid item , setting height same width (in onmeasurement), produces proper squares. data cursoradapter not show in views.

i can tell cursoradapter being referenced because number of white boxes in gridview changes depending on search.

where going wrong?

<ubiquia.sqbxsync.main.gridviewgroup xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="#ffffff">  <relativelayout     android:id="@+id/gridlayout"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:background="#ffffff">      <textview         android:id="@+id/textview1"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_alignparentleft="true"         android:layout_alignparenttop="true"         android:ellipsize="end"         android:singleline="true"         android:text="textview"         android:textsize="15dp"         android:textcolor="#ff000000" />      <textview         android:id="@+id/textview2"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_alignparentleft="true"         android:layout_below="@+id/textview1"         android:layout_marginleft="10dp"         android:ellipsize="end"         android:singleline="true"         android:text="textview"         android:textsize="11dp"         android:textcolor="#ff000000" />      <textview         android:id="@+id/textview3"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_below="@+id/textview2"         android:layout_marginleft="10dp"         android:ellipsize="end"         android:singleline="true"         android:text="textview"         android:textsize="11dp"         android:textcolor="#ff000000" />  </relativelayout> 

package ubiquia.sqbxsync.main;  import android.content.context; import android.util.attributeset; import android.view.viewgroup;  public class gridviewgroup extends viewgroup {      public gridviewgroup(context context, attributeset attrs) {         super(context, attrs);     }      @override     protected void onlayout(boolean changed, int l, int t, int r, int b) {      // nothing        }      @override     protected void onmeasure(int widthmeasurespec, int heightmeasurespec) {         super.onmeasure(widthmeasurespec, widthmeasurespec);     }   } 

my cursoradapter

public class gridcursoradapter extends cursoradapter {      public gridcursoradapter(context context, cursor c) {         super(context, c);     }      @override     public view newview(context context, cursor cursor, viewgroup parent) {         layoutinflater inflater = (layoutinflater) context.getsystemservice(context.layout_inflater_service);         view gridview = inflater.inflate(r.layout.grid_item, null, true);         return gridview;     }      @override     public void bindview(view view, context context, cursor cursor) {         textview tv1 = (textview) view.findviewbyid(r.id.textview1);         textview tv2 = (textview) view.findviewbyid(r.id.textview2);         textview tv3 = (textview) view.findviewbyid(r.id.textview3);         tv1.settext(cursor.getstring(cursor.getcolumnindexorthrow("trackingnumber")));         tv2.settext(cursor.getstring(cursor.getcolumnindexorthrow("recipient_name")));         tv3.settext(cursor.getstring(cursor.getcolumnindexorthrow("carrier_name")));     } } 

i found out after changing extends linearlayout , writing in super.onlayout(changed,l,t,r,b); shows layout in square wanted.
