Grid view to stay intact once imageview image is changed

Grid view to stay intact once imageview image is changed

Hi I am developing a game in android where in the alpha value is changed
once the image in the imageview and the image in the grid view matches. if
the number of matches are equal to 4, i need to change the image in the
imageview and again compare with the images in the grid view.
I change the image in the imageview using imageView.setImageResource(q);
The image gets changed but the grid view disappears. Could you please tell
me what I need to do for teh grid view to change intact?
I tried gridView.invalidateViews(); but in vain. I also created a new
imageadapter with the same context but it still did not work. Any help
would be really great!
