java - Android GridView make images fill screen -

how can make images in grid view fill screen?

here layout code:

<?xml version="1.0" encoding="utf-8"?> <gridview xmlns:android="http://schemas.android.com/apk/res/android"     android:id="@+id/grid_view"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:layout_margin="10dp"     android:padding="10dp"     android:columnwidth="100dp"     android:gravity="center"     android:horizontalspacing="10dp"     android:numcolumns="auto_fit"     android:stretchmode="columnwidth"     android:verticalspacing="10dp" > </gridview> 

i post picture of screen .

but displaying images small , not using entire screen.

here adapter class:

public class menucategoryadapter extends baseadapter {      private globalobjects global;     private context mcontext;      // keep objects in array     public arraylist<menucategory> categories = new arraylist<menucategory>();      // constructor     public menucategoryadapter(context c, globalobjects _global) {         mcontext = c;         global = _global;          jsonarray categoriesobj = getcategoriesfromserver();         if (categoriesobj != null) {             putcategoriesintoarray(categoriesobj);         } else {             // categories null             log.e("imageadapter", " categories null");         }     }      @override     public int getcount() {         return categories.size();     }      @override     public object getitem(int position) {         return categories.get(position);     }      @override     public long getitemid(int position) {         return 0;     }      @override     public view getview(int position, view convertview, viewgroup parent) {         imageview imageview = categories.get(position).getimg();         imageview.setscaletype(imageview.scaletype.center_crop);         imageview.setlayoutparams(new gridview.layoutparams(70, 70));         return imageview;     } }
