Create Tab Layout in Android App

This example demonstrates how do I create a Tab Layout in android app.

Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

Step 2 – Add the following dependency to create a tab layout −

implementation 'com.android.support:design:28.0.0'

Step 3 − Add the following code to res/layout/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=".MainActivity">
   <android.support.design.widget.TabLayout
      android:id="@+id/tabLayout"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:background="#1db995">
   </android.support.design.widget.TabLayout>
   <android.support.v4.view.ViewPager
      android:id="@+id/viewPager"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_below="@id/tabLayout"
      android:layout_centerInParent="true"
      android:layout_marginTop="100dp"
      tools:layout_editor_absoluteX="8dp" />
</RelativeLayout>

Step 4 − Add the following code to src/MainActivity.java

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.design.widget.TabLayout;
import android.support.v4.view.ViewPager;
public class MainActivity extends AppCompatActivity {
   TabLayout tabLayout;
   ViewPager viewPager;
   @Override
   protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      tabLayout = findViewById(R.id.tabLayout);
      viewPager = findViewById(R.id.viewPager);
      tabLayout.addTab(tabLayout.newTab().setText("Football"));
      tabLayout.addTab(tabLayout.newTab().setText("Cricket"));
      tabLayout.addTab(tabLayout.newTab().setText("NBA"));
      tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
      final MyAdapter adapter = new MyAdapter(this,getSupportFragmentManager(),
      tabLayout.getTabCount());
      viewPager.setAdapter(adapter);
      viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
      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) {
         }
      });
   }
}

Step 5 – Create a java class(MyAdapter.java) and add the following code −

import android.content.Context;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.app.FragmentManager;
class MyAdapter extends FragmentPagerAdapter {
   Context context;
   int totalTabs;
   public MyAdapter(Context c, FragmentManager fm, int totalTabs) {
      super(fm);
      context = c;
      this.totalTabs = totalTabs;
   }
   @Override
   public Fragment getItem(int position) {
      switch (position) {
         case 0:
            Football footballFragment = new Football();
         return footballFragment;
         case 1:
            Cricket cricketFragment = new Cricket();
         return cricketFragment;
         case 2:
            NBA nbaFragment = new NBA();
         return nbaFragment;
         default:
         return null;
      }
   }
   @Override
   public int getCount() {
      return totalTabs;
   }
}

Step 6 – Now create the fragments and the layouts (Right click on the project >> New >> Fragment >> Blank −

a) FootBall.java

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class Football extends Fragment {
   public Football() {
      // Required empty public constructor
   }
   @Override
   public View onCreateView(LayoutInflater inflater, ViewGroup container,
    Bundle savedInstanceState) {
      return inflater.inflate(R.layout.fragment_football, container, false);
   }
}

fragment_football.xml

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout 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=".Football">
   <!-- TODO: Update blank fragment layout -->
   <TextView
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:textAlignment="center"
      android:text="Football Fragment"
      android:textSize="16sp"
      android:textStyle="bold"/>
</FrameLayout>

b) Cricket.java

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class Cricket extends Fragment {
   public Cricket() {
      // Required empty public constructor
   }
   @Override
   public View onCreateView(LayoutInflater inflater, ViewGroup container,
    Bundle savedInstanceState) {
      return inflater.inflate(R.layout.fragment_cricket, container, false);
   }
}

fragment_cricket.xml

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout 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=".Cricket">
   <TextView
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:textAlignment="center"
      android:text="Cricket Fragment"
      android:textSize="16sp"
      android:textStyle="bold"/>
</FrameLayout>

c) NBA.java

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class NBA extends Fragment {
   public NBA() {
      // Required empty public constructor
   }
   @Override
   public View onCreateView(LayoutInflater inflater, ViewGroup container,
    Bundle savedInstanceState) {
      return inflater.inflate(R.layout.fragment_nb, container, false);
   }
}

fragment_nba.xml

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout 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=".NBA">
   <!-- TODO: Update blank fragment layout -->
   <TextView
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:textAlignment="center"
      android:text="NBA Fragment"
      android:textSize="16sp"
      android:textStyle="bold"/>
</FrameLayout>

Step 7 - Add the following code to androidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
   package="app.com.sample">
   <application
      android:allowBackup="true"
      android:icon="@mipmap/ic_launcher"
      android:label="@string/app_name"
      android:roundIcon="@mipmap/ic_launcher_round"
      android:supportsRtl="true"
      android:theme="@style/AppTheme">
      <activity android:name=".MainActivity">
         <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
         </intent-filter>
      </activity>
   </application>
</manifest>

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click Run  icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen –
