问题
I am implementing a GridView which contains images.
I want to expand an image to occupy the whole row when it's clicked as shown in the images below.
I also want to show a button when the image is expanded so the user can take an action similar to how the ESPN app does that.
How can I achieve this?

Surround your layout with a relative layout. Create a layout and a button inside it outside grid layout/inside relative layout. Set it's initial visibility to gone and match it's height, width to row you want it to encompass. Then in the onclick of the image set the layouts view to visible and it's button. Perhaps not perfect but it has the added benefit of allowing scrolling of your gridview while showing the big image you want.
