Android List Fragment

List Fragment:

ListFragment in Android is the fragment which contains list of items.

It is particularly useful when you want to show a scrollable list of items and you get a neat way how to manage the UI for the list in this fragment.

The ListFragment class makes creating and handling lists easier and more efficient for your app.

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=".ListFragmentExample"
        android:layout_marginLeft="16dp"
        >
    
       <ListView
           android:id="@+id/list_fragment1"
           android:layout_width="match_parent"
           android:layout_height="match_parent"
           />
   
</LinearLayout>
