How to display ListView in Fragments using ViewPagers?

Please Share On:

Here, I will show you the whole process of how can you display your listview in fragments using view pagers.

Steps to follow:

Here are the steps you need to follow to create a listview in the fragment.

Add Design Support Dependencies
Create TabLayout Fragment with ListView: tab1.xml and tab2.xml
Create Java class for tab1.java and tab2.java
Create a ViewPagerAdapter in Java class. For example: ViewPagerAdapter.java
Creating CustomAdapater
Remove ActionBar
Design your TabLayout and ViewPager in activity_main.xml
Add code in MainActivity.java
Create header_item.xml to display listitem titles
Create main_toolbar.xml
Create colors.xml
Create strings.xml

See the below diagrams, we need to create accordingly.

Now, Let’s proceed in detail from step 1 to step 7.

1) Add Design Support Dependencies:

You can add your Android design support dependencies into either way:

1.1) Add directly in your Project Module: build.gradle

Open App -> Gradle Scripts ->build.gradle(Module: Your_Project_Name.app)

Add the below code inside dependencies

dependencies
{
implementation 'com.google.android.material:material:1.4.0'
}

OR

2.1) Select File -> Project Structure

2.2) Select Dependencies and click “+” sign

Choose “Library Dependencies” and select your Design Support Dependencies and click OK.

2) Create TabLayout Fragment: tab1.xml and tab2.xml

Now, you have to create tab1.xml and tab2.xml files. In the above screenshot, You can see that I have used only two tabs. If you need more than two tabs, create tab3.xml, tab4.xml accordingly, or your own name XML file.

Here, you will design your XML file accordingly to what exactly you want to display on your fragment page. Here, I have created a ListView to display items in a list.

Tab1.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ads="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/colorAccent"
    android:padding="10dp">

    <ListView
        android:id="@+id/listView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/colorAccent"/>

</RelativeLayout>

Tab2.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:ads="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/background"
    android:padding="10dp">

    <ListView
        android:id="@+id/listView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/background"/>

</RelativeLayout>

3) Create Java class for tab1 and tab2

For tab1.xml and tab2.xml layout resource files, you need to create two java classes that will contain these resources as fragments.

Add some code in Tab1.java and Tab2.java classes

Tab1.java

package com.geetaregmi.tabactivity;

import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ListView;

import androidx.fragment.app.Fragment;

import java.util.ArrayList;


public class Tab1 extends Fragment {
    ListView list;
    View view;

    public Tab1() {
    }

    //Overridden method onCreateView
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        view = inflater.inflate(R.layout.tab1, container, false);

        list = view.findViewById(R.id.listView);
        ArrayList<String> title= new ArrayList<>();

        title.add("Item 1");
        title.add("Item 2");
        title.add("Item 3");
        title.add("Item 4");
        title.add("Item 5");
        title.add("Item 6");
        title.add("Item 7");
        title.add("Item 8");
        title.add("Item 9");
        title.add("Item 10");
        title.add("Item 11");
        title.add("Item 12");
        title.add("Item 13");
        title.add("Item 14");
        title.add("Item 15");
        title.add("Item 16");
        title.add("Item 17");
        title.add("Item 18");
        title.add("Item 19");
        title.add("Item 20");

        CustomAdapter adapter = new CustomAdapter(title,getActivity());
        list.setAdapter(adapter);

        return view;
    }
}

Tab2.java

package com.geetaregmi.tabactivity;

import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ListView;

import androidx.fragment.app.Fragment;

import java.util.ArrayList;


public class Tab2 extends Fragment {
    ListView list;
    View view;

    public Tab2() {
    }

    //Overridden method onCreateView
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        view = inflater.inflate(R.layout.tab2, container, false);

        list = view.findViewById(R.id.listView);
        ArrayList<String> title= new ArrayList<>();

        title.add("Item 1");
        title.add("Item 2");
        title.add("Item 3");
        title.add("Item 4");
        title.add("Item 5");
        title.add("Item 6");
        title.add("Item 7");
        title.add("Item 8");
        title.add("Item 9");
        title.add("Item 10");
        title.add("Item 11");
        title.add("Item 12");
        title.add("Item 13");
        title.add("Item 14");
        title.add("Item 15");
        title.add("Item 16");
        title.add("Item 17");
        title.add("Item 18");
        title.add("Item 19");
        title.add("Item 20");

        CustomAdapter adapter = new CustomAdapter(title,getActivity());
        list.setAdapter(adapter);

        return view;
    }
}

4) Create a View Pager Adapter in Java class

Now create a View Pager Adapter java class and name it as ViewPagerAdapter.java and Paste the below code inside it.

ViewPagerAdapter.java

package com.geetaregmi.tabactivity;

import androidx.annotation.NonNull;
import androidx.fragment.app.Fragment;
import androidx.fragment.app.FragmentManager;
import androidx.fragment.app.FragmentPagerAdapter;
import androidx.fragment.app.FragmentStatePagerAdapter;

public class ViewPagerAdapter extends FragmentPagerAdapter {

    //integer to count number of tabs
    int tabCount;


    //Constructor to the class
    public ViewPagerAdapter(FragmentManager fm) {
        super(fm);
    }


    //Overriding method getItem
    @NonNull
    @Override
    public Fragment getItem(int position) {
        //Returning the current tabs
        switch (position) {
            case 0:
                return new Tab1();
            case 1:
                return new Tab2();
            default:
                return null;
        }
    }

    //Overriden method getCount to get the number of tabs
    @Override
    public int getCount() {
        return 2;
    }

    @Override
    public CharSequence getPageTitle(int position) {
        String title = null;
        if (position == 0)
        {
            title = "list";
        }
        else if (position == 1)
        {
            title = "Collect";
        }
        return title;
    }
}

5) Creating CustomAdapter

Now, you need to create your custom adapter and name as CustomAdapter.java

package com.geetaregmi.tabactivity;

import android.content.Context;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.TextView;

import androidx.annotation.Nullable;

import java.util.ArrayList;

public class CustomAdapter extends ArrayAdapter {
    private final ArrayList headerItem;
    Context context;

    // View lookup cache
    private static class ViewHolder {
        TextView txtName;

    }

    public CustomAdapter(ArrayList data, Context context) {
        super(context, R.layout.header_item, data);
        this.headerItem = data;
        this.context = context;

    }

    @Nullable
    @Override
    public String getItem(int position) {
        return (String) headerItem.get(position);
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {

        ViewHolder viewHolder;

        if (convertView == null) {
            viewHolder = new ViewHolder();
            LayoutInflater inflater = LayoutInflater.from(getContext());
            convertView = inflater.inflate(R.layout.header_item, parent, false);
            viewHolder.txtName = (TextView) convertView.findViewById(R.id.title);
            convertView.setTag(viewHolder);
        } else {
            viewHolder = (ViewHolder) convertView.getTag();
        }

        viewHolder.txtName.setText(getItem(position));
        return convertView;
    }
}

6) Remove Actionbar

Here, you have to remove your Actionbar and use the toolbar instead. To do this add the below code to your styles.xml file located under the values folder.

<resources> 
<!-- changing it to no actionbar -->
    <style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
        <!-- Customize your theme here. -->
        <item name="colorPrimary">@color/colorPrimary</item>
        <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
        <item name="colorAccent">@color/colorAccent</item>
    </style>


</resources>

7) Design your TabLayout and ViewPager in activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <com.google.android.material.appbar.AppBarLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <com.google.android.material.tabs.TabLayout
            android:id="@+id/tabLayout"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:background="@color/blue"
            app:tabSelectedTextColor="@color/white"
            app:tabTextColor="@color/white"
            tools:ignore="SpeakableTextPresentCheck" />
    </com.google.android.material.appbar.AppBarLayout>

    <androidx.viewpager.widget.ViewPager
        android:id="@+id/viewPager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_behavior="@string/appbar_scrolling_view_behavior"
        tools:ignore="SpeakableTextPresentCheck" />

</androidx.coordinatorlayout.widget.CoordinatorLayout>

8) MainActivity.java

Now, you have to add some code in your main activity to function your tab Layout.

package com.geetaregmi.tabactivity;

import android.os.Bundle;

import com.google.android.material.tabs.TabLayout;

import androidx.appcompat.widget.Toolbar;
import androidx.viewpager.widget.ViewPager;
import androidx.appcompat.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {

    //Declare your TabLayout and ViewPager
    private TabLayout tabLayout;
    private ViewPager viewPager;

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

       //Replace action bar into toolbar
        Toolbar mToolbar = findViewById(R.id.toolbar);
        setSupportActionBar(mToolbar); // Setting replace toolbar as the ActionBar

        //Initializing the tabLayout and viewLayout
        tabLayout = findViewById(R.id.tabLayout);
        viewPager = findViewById(R.id.viewPager);

        //Creating our pager adapter
        ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());

        //Adding adapter to pager
        viewPager.setAdapter(adapter);

        //setUpWithViewPager is used to join tabLayout and viewPager
        tabLayout.setupWithViewPager(viewPager);

        //Adding onTabSelectedListener to swipe views
        tabLayout.addOnTabSelectedListener(new TabLayout.OnTabSelectedListener() {
           @Override
           public void onTabSelected(TabLayout.Tab tab) {
               viewPager.setCurrentItem(tab.getPosition());
           }

           @Override
           public void onTabUnselected(TabLayout.Tab tab) {

           }

           @Override
           public void onTabReselected(TabLayout.Tab tab) {

           }

        });
    }
}

9) Create header_item.xml to display listitem titles

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
        android:id="@+id/title"
        android:layout_width="0dp"
        android:layout_height="40dp"
        android:layout_weight="1"
        android:textSize="16dp"
        android:gravity="center_vertical"
        android:textColor="@color/black"
        android:text="TextView" />
</LinearLayout>

10) Create main_toolbar.xml

<?xml version="1.0" encoding="utf-8"?>
<androidx.coordinatorlayout.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <androidx.appcompat.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/blue"
        android:elevation="4dp"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"
        app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
        app:title="Tab layout"
        app:navigationIcon="@drawable/ic_baseline_menu_24"/>

</androidx.coordinatorlayout.widget.CoordinatorLayout>

11) Create colors.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="colorPrimary">#6200EE</color>
    <color name="colorPrimaryDark">#3700B3</color>
    <color name="colorAccent">#03DAC5</color>
    <color name="background">#CED6E0</color>
    <color name="blue">#4B6584</color>
    <color name="purple_200">#FFBB86FC</color>
    <color name="purple_500">#FF6200EE</color>
    <color name="purple_700">#FF3700B3</color>
    <color name="teal_200">#FF03DAC5</color>
    <color name="teal_700">#FF018786</color>
    <color name="black">#FF000000</color>
    <color name="white">#FFFFFFFF</color>
    <color name="orange">#FFA500</color>
</resources>

12) strings.xml

<resources>
    <string name="app_name">TabActivity</string>
    <string name="tab_text_1">Tab 1</string>
    <string name="tab_text_2">Tab 2</string>
</resources>

Now, run your application you will get exactly the same output as shown below screenshot:
