Buat tampilan parent (activity_main.xml)

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">
    <android.support.v7.widget.Toolbar

        android:id="@+id/toolbar"

        android:layout_width="match_parent"

        android:layout_height="wrap_content"

        android:layout_alignParentTop="true"

        android:background="?attr/colorPrimary"

        android:elevation="6dp"

        android:minHeight="?attr/actionBarSize"

        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"

        app:popupTheme="@style/ThemeOverlay.AppCompat.Light"/>
<android.support.design.widget.TabLayout
        android:id="@+id/sliding_tabs"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:tabMode="scrollable" />

    <android.support.v4.view.ViewPager
        android:id="@+id/viewpager"
        android:layout_width="match_parent"
        android:layout_height="0px"
        android:layout_weight="1"
        android:background="@android:color/white" />

</LinearLayout>

Tampilan Tab 1 (tab_fragment_1.xml)

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

                android:layout_width="match_parent"

                android:layout_height="match_parent"

                android:orientation="vertical">

 

    <TextView

        android:id="@+id/textView"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_centerInParent="true"

        android:text="Tab 1"

        android:textAppearance="?android:attr/textAppearanceLarge"/>

 

</RelativeLayout>

Tampilan Tab 2 (tab_fragment_2.xml)

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

                android:layout_width="match_parent"

                android:layout_height="match_parent"

                android:orientation="vertical">

 

    <TextView

        android:id="@+id/textView"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_centerInParent="true"

        android:text="Tab 2"

        android:textAppearance="?android:attr/textAppearanceLarge"/>

 

</RelativeLayout>

Tab 1 (TabFragment1.java)

package com.truiton.designsupporttabs;

 

import android.os.Bundle;

import android.support.v4.app.Fragment;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

 

public class TabFragment1 extends Fragment {

 

    @Override

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

        return inflater.inflate(R.layout.tab_fragment_1, container, false);

    }

}

dapat juga digunakan dengan mengimplementasikan Librari ButterKnife
Tab 1 (TabFragment1.java)

package com.truiton.designsupporttabs;

 

import android.os.Bundle;

import android.support.v4.app.Fragment;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

 

public class TabFragment1 extends Fragment {

 

    @Override

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

        View view = inflater.inflate(R.layout.tab_fragment_1, container, false);
        ButterKnife.bind(this, view);
        return view;

    }

}

Tab 2 (TabFragment2.java)

package com.truiton.designsupporttabs;

 

import android.os.Bundle;

import android.support.v4.app.Fragment;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

 

public class TabFragment2 extends Fragment {

 

    @Override

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

        return inflater.inflate(R.layout.tab_fragment_2, container, false);

    }

}

dapat juga digunakan dengan mengimplementasikan Librari ButterKnife
Tab 2 (TabFragment2.java)

package com.truiton.designsupporttabs;

 

import android.os.Bundle;

import android.support.v4.app.Fragment;

import android.view.LayoutInflater;

import android.view.View;

import android.view.ViewGroup;

 

public class TabFragment2 extends Fragment {

 

    @Override

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

        View view = inflater.inflate(R.layout.tab_fragment_2, container, false);
        ButterKnife.bind(this, view);
        return view;

    }

}

Parent (MainActivity.java) ....(1)

import android.os.Bundle;

import android.support.design.widget.TabLayout;

import android.support.v4.view.ViewPager;

import android.support.v7.app.AppCompatActivity;

import android.support.v7.widget.Toolbar;

import android.view.Menu;

import android.view.MenuItem;

 

 

public class MainActivity extends AppCompatActivity {

 

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_main);

        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);

        setSupportActionBar(toolbar);

 

        TabLayout tabLayout = (TabLayout) findViewById(R.id.sliding_tabs);

        tabLayout.addTab(tabLayout.newTab().setText("Tab 1"));

        tabLayout.addTab(tabLayout.newTab().setText("Tab 2"));

        tabLayout.addTab(tabLayout.newTab().setText("Tab 3"));

        tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);

 

        final ViewPager viewPager = (ViewPager) findViewById(R.id.viewpager);

        final PagerAdapter adapter = new PagerAdapter

                (getSupportFragmentManager(), tabLayout.getTabCount());

        viewPager.setAdapter(adapter);

        viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));

        tabLayout.setOnTabSelectedListener(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) {

 

            }

        });

    }

 

    @Override

    public boolean onCreateOptionsMenu(Menu menu) {

        getMenuInflater().inflate(R.menu.menu_main, menu);

        return true;

    }

 

    @Override

    public boolean onOptionsItemSelected(MenuItem item) {

        int id = item.getItemId();

        if (id == R.id.action_settings) {

            return true;

        }

 

        return super.onOptionsItemSelected(item);

    }

}

dapat juga di implementasikan ke fragment
Parent (MainActivity.java) ....(2)

import android.os.Bundle;

import android.support.design.widget.TabLayout;

import android.support.v4.view.ViewPager;

import android.support.v7.app.AppCompatActivity;

import android.support.v7.widget.Toolbar;

import android.view.Menu;

import android.view.MenuItem;

 

 

public class MainActivity extends Fragment {

 

    @Override

    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.activity_main, container, false);
        

        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);

         AppCompatActivity activity = (AppCompatActivity) getActivity();
         activity.setSupportActionBar(toolbar); 


        TabLayout tabLayout = (TabLayout) findViewById(R.id.sliding_tabs);

        tabLayout.addTab(tabLayout.newTab().setText("Tab 1"));

        tabLayout.addTab(tabLayout.newTab().setText("Tab 2"));

        tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);

 

        final ViewPager viewPager = (ViewPager) findViewById(R.id.viewpager);

        final PagerAdapter adapter = new PagerAdapter

                (getSupportFragmentManager(), tabLayout.getTabCount());

        viewPager.setAdapter(adapter);

        viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));

        tabLayout.setOnTabSelectedListener(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) {

 

            }

        });

    return view;
    }

 

    @Override

    public boolean onCreateOptionsMenu(Menu menu) {

        getMenuInflater().inflate(R.menu.menu_main, menu);

        return true;

    }

 

    @Override

    public boolean onOptionsItemSelected(MenuItem item) {

        int id = item.getItemId();

        if (id == R.id.action_settings) {

            return true;

        }

 

        return super.onOptionsItemSelected(item);

    }

}       

Ketika kita menggunakan Lybrary ButterKnife itu akan menjadi lebih mudah
Parent (MainActivity.java) ....(3)

import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.design.widget.TabLayout;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

import java.io.IOException;

import butterknife.Bind;
import butterknife.ButterKnife;

public class MainActivity extends Fragment implements TabLayout.OnTabSelectedListener {

    @Bind(R.id.toolbar)
    Toolbar toolbar;
    @Bind(R.id.sliding_tabs)
    TabLayout tabLayout;
    @Bind(R.id.pager)
    ViewPager viewpager;

    private PagerAdapter adapter;

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.activity_main, container, false);
        ButterKnife.bind(this, view);

        AppCompatActivity activity = (AppCompatActivity) getActivity();
        activity.setSupportActionBar(toolbar);
        return view;
    }

    @Override
    public void onViewCreated(View view, Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        setupTab();
        setupPager();

    }

    private void setupTab() {
        tabLayout.addTab(tabLayout.newTab().setText("Tab 1"));
        tabLayout.addTab(tabLayout.newTab().setText("Tab 2"));
        tabLayout.setTabGravity(TabLayout.GRAVITY_FILL);
        tabLayout.setOnTabSelectedListener(this);
    }

    private void setupPager() {
        adapter = new ProfilAdapter
                (((AppCompatActivity) getActivity()).getFragmentManager(), tabLayout.getTabCount());
        viewPager.setAdapter(adapter);
        viewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
    }

    @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) {

    }
}

untuk dapat menampilkan pager, kita membutuhkan sebuah class adaptor

kelas adaptor (PagerAdaptor.java)

import android.support.v4.app.Fragment;

import android.support.v4.app.FragmentManager;

import android.support.v4.app.FragmentStatePagerAdapter;

 

public class PagerAdapter extends FragmentStatePagerAdapter {

    int mNumOfTabs;

 

    public PagerAdapter(FragmentManager fm, int NumOfTabs) {

        super(fm);

        this.mNumOfTabs = NumOfTabs;

    }

 

    @Override

    public Fragment getItem(int position) {

 

        switch (position) {

            case 0:

                TabFragment1 tab1 = new TabFragment1();

                return tab1;

            case 1:

                TabFragment2 tab2 = new TabFragment2();

                return tab2;

            default:

                return null;

        }

    }

 

    @Override

    public int getCount() {

        return mNumOfTabs;

    }

}
