Fragment In Android | CodersArts

A Fragment is a combination of an XML layout file and a java class much like an Activity . Using the support library, fragments are supported back to all relevant Android versions. Fragments encapsulate views and logic so that it is easier to reuse within activities.

Fragment basically use in navigation when we are wanted home page and User information page and tracking kind of things in a single page then we have to implement fragment

we have to create fragment activity for mutiple users

package com.example.app;
import android.content.Context;
import androidx.annotation.NonNull;
import androidx.fragment.app.Fragment;
import androidx.fragment.app.FragmentManager;
import androidx.fragment.app.FragmentPagerAdapter;
publicclass MyAdapter extends FragmentPagerAdapter 
{
   privateContext myContext;
   int totalTabs;
   public MyAdapter(Contextcontext, FragmentManagerfm,  inttotalTabs) 
{
    super(fm);       
    myContext = context;this.totalTabs = totalTabs;    
}
@NonNull
@Overridepublic
Fragment getItem(intposition)
 {
switch (position)
 {
    case 0:
       BlankFragment blankFragment =newBlankFragment();
       return blankFragment;
    case1:      
          chat chat =new chat();
          return chat;
     case2: 
           home home =new home();
           return home;
      default:returnnull; 
       } 
   }
@Override
