How to change code from Gallery View to Grid View using same practical
In Android, Gallery is a view used to show items in a center locked, horizontal scrolling list and user will select a view and then user selected view will be shown in the center of the Horizontal list. The items in Gallery are added using Adapter just like in ListView or GridView.
Important Note: Gallery class was deprecated in API level 16. This widget is no longer supported. Other horizontally scrolling widgets include HorizontalScrollView and ViewPager from the support library.
Adapters works as a bridge between AdapterView and data source. For filling data(images) in Gallery we need to use Adapters. BaseAdapter is parent adapter for all other adapters so we mainly used it for displaying data in Gallery list.
BaseAdapter is a common base class of a general implementation of an Adapter that can be used in ListView, GridView, Gallery etc. Base Adapter can be extended to create a custom Adapter for displaying a custom list items.
