Android ListFragment Example

ListFragment

A fragment that displays a list of items by binding to a data source such as an array or Cursor, and exposes event handlers when the user selects an item.

The basic implementation of list fragment is for creating list of items in fragments.

Let’s have a look at the simple example of android ListFragment.

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout 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="com.example.lenovo.listfragmentapp.MainActivity">

    <FrameLayout
        android:id="@+id/frame_layout"
        class="com.example.lenovo.listfragmentapp.FragmentA"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        />

</RelativeLayout>

fragment1.xml

<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="com.example.lenovo.listfragmentapp.FragmentA">


    <ListView
        android:id="@id/android:list"
        android:layout_width="match_parent"
        android:layout_height="match_parent">

    </ListView>

</LinearLayout>

MainActivity.Java

package com.example.lenovo.listfragmentapp;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        FragmentA fragment1 = new FragmentA();
        getSupportFragmentManager().beginTransaction().replace(R.id.frame_layout, fragment1).commit();
    }

}

Fragment1.Java

package com.example.lenovo.listfragmentapp;

import android.os.Bundle;
import android.support.v4.app.ListFragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;


public class Fragment1 extends ListFragment {

    String[] code_name = {"Froyo", "GingerBread", "HoneyComb", "IceCream Sandwich", "JellyBean", "Kitkat", "Lollipop", "Marshmallow", "Nougat", "Oreo"};


    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

        View view = inflater.inflate(R.layout.fragment1, container, false);
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(inflater.getContext(), android.R.layout.simple_list_item_1, code_name);
        setListAdapter(adapter);
        return view;

    }

    @Override
    public void onListItemClick(ListView l, View v, int position, long id) {
        Toast.makeText(getActivity().getBaseContext(), code_name[position], Toast.LENGTH_SHORT).show();
    }
}

When you run the app it will look like this:
