Android GridView

GridView:

GridView is a view group that is responsible for showing objects in a two-dimensional, scrollable table.

It is information represented in rows and columns and is a popular and effective way to deliver information since each cell of the grid is clickable and interactive.

Example:

                                    
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        tools:context=".GridViewExample"
        android:orientation="vertical">
    
        <GridView
           android:id="@+id/gridview"
           android:layout_width="match_parent"
           android:layout_height="match_parent"
           android:numColumns="2"/>
   
</LinearLayout>
