    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;
        }
    }
    

    }
