Delete items by selecting whole row in GridView Android

I have a Gridview with 3 columns

  <GridView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/gridView"        
    android:numColumns="3"     />

When I select it I see that it is highlighted the selected item. I want to Highlight the selected row to remove it and not only the item. Is it possible? Is it better to use another UI control from Gridview?

Do this way, I just add logic. you have to do it batter way. all the best.

public void selectRow(int selectedItemPos)
  {
    int TotlaItemInGrid = 17;
    int lastpos = TotlaItemInGrid-1;
    //0 1 2
    //3 4 5
    //6 7 8
    //9 10 11
    //12 13 14
    //15 16

    // case 1 if user select first row
    // in this condition position 0,1,2 will fix
    if(selectedItemPos == 0 || selectedItemPos==1 || selectedItemPos==2)
    {

      for(int pos =selectedItemPos ; pos<=lastpos; (pos+2))
      {
        // do selection
        // if you select 0 then here you will get result like 0,3,6,9...
        // if you select 0 then here you will get result like 1,4,7,10...
        // if you select 0 then here you will get result like 2,5,8,11..,
      }
    }

    // case 2 if user select last row
    // 
    else if(selectedItemPos == lastpos || selectedItemPos==(lastpos-1) || selectedItemPos==(lastpos-2))
    {
      for(int pos =selectedItemPos ; pos>=0; (pos-2))
      {
        // do selection

      }

    }

    // case 3 in between first and last row
    else
    {
      for(int pos =selectedItemPos ; pos>=0;(pos-2))
      {
        // do selection

      }
      for(int pos =selectedItemPos ; pos<=lastpos; (pos+2))
      {
        // do selection

      }

    }

  }

yes it is possible. while you select any item skip two position like if selected is 0 then next selection ll set on p+2 = 2nd position then and select all other position so by this way you can select your whole row. do same thing while you wan to remove data of selected row.
