Lecture 20: Android GridView with Example

Android GridView with Example:
In android, Grid View is a ViewGroup that is used to display items in a two dimensional, scrollable grid and grid items are automatically inserted to the gridview layout using a list adapter.
Generally, the adapter pulls data from sources such as an array or database and converts each item into a result view and that’s placed into the list.
In android, Adapter will act as an intermediate between the data sources and adapter views such as ListView, Gridview to fill the data into adapter views.
We have a different types of adapters available to fetch the data from different data sources to fill the data into adapter views, those are:
1.ArrayAdapter: It will expect an Array or List as input.
2.CurosrAdapter: It will accept an instance of a cursor as an input.
3.SimpleAdapter: It will accept a static data defined in the resources.
Here, we can bind number of images to GridView using Adapter in android applications based on our requirements.
Once we are done with creation of layout.xml file, we need to create a custom adapter as ImageAdapter.java file by extending it using BaseExtender class to show all the items in the grid.
Now we will bind images to our GridView using our custom adapter that is ImageAdapter.java.
