Center children in a GridView

Question

I've got a 3 column GridView and 4 items.

So it happens that three of them appear on the first row, and the last one in the second row, but this one aligned to the left. I just wanted to know if there is possible to make it appear centered in the GridView. Like a 'T', I don't know if I explain... xD

Thank you :-)

Edit:

This is the layout that contains the GridView

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/section_title_root"
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"
    android:background="@drawable/bg_gd_home_grid">
    <ImageView
    android:src="@drawable/home_grid_txori"
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content"
    android:layout_marginTop="40dip"
    android:layout_centerHorizontal="true"/>
    <GridView
        android:id="@+id/home_grid"
        android:layout_width="wrap_content" 
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:numColumns="3"
        android:drawSelectorOnTop="true"
        android:layout_marginBottom="30dip"
        android:layout_marginLeft="30dip"
        android:layout_marginRight="30dip"
        android:padding="5dip"
        android:listSelector="@android:color/transparent"
        android:background="@drawable/bg_home_grid_item"
/>
</RelativeLayout>

By the way, android:layout_centerHorizontal="true" doesn't work in GridView

Solution Edit:

This issue is from years past, but I've been asked to post the solution and I had to find my old repo to get it :-)

As I said bellow in the comments, I couldn't achieve it only usin XML, so I had to trick a fake non-clickable + non-focusable item in 3rd position.

It was my first App ever, so I didn't implement the recommended "ViewHolder" solution. I strongly recommend its usage

This is how my getView() method looks like in the Adapter:

public View getView(int position, View convertView, ViewGroup parent) {

        if (convertView == null) {

            convertView = (RelativeLayout) mInflater.inflate(
                    R.layout.home_grid_item, null);

        }

        /* In order to have 4th item centered in the 2nd row, we create an empty 3rd item */
        if (position == 3) {
            convertView.setFocusable(false);
            convertView.setClickable(false);
        } else {
            ImageView imageView = (ImageView) convertView
                    .findViewById(R.id.image);
            imageView.setImageResource(mThumbs[position]);
            TextView textView = (TextView) convertView.findViewById(R.id.title);
            textView.setText(mTitles[position]);

        }

        convertView.setTag(mTabTags[position]);

        return convertView;
    }

You can try the following code:

android:gravity="center_horizontal"

in the xml.
