Center elements in GridView

Question

I have GridView with 6 images in 2 columns. I want to display this 6 images in the middle of the screen. I set gravity properties to center but this center elements only hor

Answer 1

I found that you just have the gridlayout wrap content on height and width.

android:layout_centerHorizontal="true"

It will center itself for the size it needs but if you have it matching the parent. You are technically centering it based with a lot of parent empty space offsetting your children.

Answer 2

Try to change this:
android:layout_height="fill_parent"
into
android:layout_height="wrap_content"

You are now telling your grid view to fill it's parent height and width fully.

Answer 3

Try wrapping your GridView in a LinearLayout that has it's child elements centered and change your gridview's layout_height to "wrap_content". ex:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_height="fill_parent"
  android:layout_width="fill_parent"
  android:gravity="center"
  android:layout_gravity="center">
    <GridView 
      android:id="@+id/homeGridView"
      android:layout_width="fill_parent"
      android:layout_height="wrap_content"
      android:numColumns="3"
      android:verticalSpacing="10dp"
      android:horizontalSpacing="10dp"
      android:stretchMode="columnWidth"
      android:gravity="center" />
</LinearLayout>
