Gallery and ImageView Views
The Gallery is a view that shows items (such as images) in a
center-locked, horizontal scrolling list. Figure 5-1 shows how
the Gallery view looks when it is displaying some images.
The following Try It Out shows you how to use the Gallery
view to display a set of images.
ImageSwitcher
The previous section demonstrated how to use the Gallery view together with an ImageView to
display a series of thumbnail images so that when one is selected, it is displayed in the ImageView.
However, sometimes you don’t want an image to appear abruptly when the user selects it in the
Gallery view — you might, for example, want to apply some animation to the image when it
GridView
The GridView shows items in a two-dimensional scrolling grid. You can use the GridView together
with an ImageView to display a series of images.
