Fiz assim:

package br.me.gridview;

import android.app.Activity;
import android.os.Bundle;
import android.widget.GridView;
import br.me.gridview.ButtonAdapter; 

public class GridViewActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        GridView gridView = (GridView) findViewById(R.id.gridView);  
        gridView.setAdapter(new ButtonAdapter(this, new String[] {"Item 1", "Item 2", "Item 3"})); // ainda sublinhado new ButtonAdapter(this, new String[] {"Item 1", "Item 2", "Item 3"}) 
    }
}
