Setting up GridViewįirst, create a new Android project, GridViewTest. There’s a handy online tutorial available for GridLayout. If you’re using other layouts and find yourself trying to nest them to multiple levels, it may be worth looking into using a GridLayout instead and it’s arguably easier to learn if you’re starting from scratch than some of the other layouts. The children are defined as occupying a particular cell or cells in the layout, which makes particular layouts easier to manage and to arrange attractively. This is a layout whose children are placed into a rectangular grid. (A 1024×768 image still takes up the same amount of memory when it is displayed in a 200×150 box.) Create small thumbnails if your image files are large, to avoid the Android VM running out of memory.Ī GridLayout is also available from API 14. However, you still need to make sure that your image files are an appropriate size. As you scroll, the memory and resources used for the images scrolling off the page can be reused for the ones scrolling on.

One of the advantages of a GridView is that, like a ListView, it only needs to keep in memory the images that are visible at any one time. Read on for an example of how to set up a GridView with a list of images, which when you click on an image, launches a webpage associated with it. This, as you might expect, lays out your list as a scrollable grid of images. Another, which is great if your list is best represented by images, is GridView. One option for this is a ListView (as discussed in this tutorial). A common use case in Android, though, is that you have a list of items to display, which you wish the user to be able to click on. In previous layout tutorials, we’ve looked at LinearLayout and RelativeLayout.
