Answer 1

A step forward and it works

public class ListViewA extends Activity {
GridView MyGrid;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    MyGrid = (GridView) findViewById(R.id.gridview);
    MyGrid.setAdapter(new ImageAdapter(this));
}

public class ImageAdapter extends BaseAdapter {
    Context MyContext;

    public ImageAdapter(Context _MyContext) {
        MyContext = _MyContext;
    }

    @Override
    public int getCount() {
        return 9;
    }

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

        if (convertView == null) {

            LayoutInflater li = getLayoutInflater();
            view = li.inflate(R.layout.main, null);
        }

        if (position % 2 == 0)
            view.setBackgroundColor(0x30FF0000);
        else
            view.setBackgroundColor(0x300000FF);
        return view;

    }

    @Override
    public Object getItem(int arg0) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public long getItemId(int arg0) {
        // TODO Auto-generated method stub
        return 0;
    }
}

}

If you got a lot of examples for listView, why not just use getView method, as getView method is used for adapter and adapter is used in both views, list and grid. just set background of view according to the position of view in adapterview.

protected void getView(AdapterView<> adapterView, View convertView, int position, long id)
{

    LayoutInflater inflater = (LayoutInflater)context.getSystemService
      (Context.LAYOUT_INFLATER_SERVICE);
    View view =inflater.inflate(yourlayout.xml, null);

    if(position%2==0)
        view.setBackgroundColor(color1);
    else
        view.setBackgroundColor(color2);
     return view;
}
