Хотите разработать макет вкладки с помощью стрелок вправо и влево

Question

Я разработал макет вкладки и могу прокручивать, проводя по вкладкам, но моя цель - получить стрелки вправо и влево для перехода между вкладками, которые видели несколько уроков и блогов, но ни одна из них не помогла мне выйти из этого

Макет вкладки, показанный на рисунке, хочу создать таким же образом.

активность

package com.example.panel_monitoring.activities;

import android.content.Intent;
import android.support.design.widget.TabLayout;
import android.support.v4.view.PagerAdapter;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.Toolbar;
import android.view.View;
import android.widget.Button;
import android.widget.TableLayout;
import android.widget.Toast;

import com.example.panel_monitoring.R;

public class feeder_1 extends AppCompatActivity {

    private Toolbar toolbar2;
    private TabLayout tabLayout;
    private Button up,down;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate( savedInstanceState );
        setContentView( R.layout.activity_feeder_1 );
        toolbar2 = (Toolbar)findViewById( R.id.toolbar2 );
        toolbar2.setTitle( R.string.app_name );

        tabLayout = (TabLayout) findViewById( R.id.tablayout_feeder_1);
        tabLayout.addTab(tabLayout.newTab().setText("<<"));
        tabLayout.addTab(tabLayout.newTab().setText("Tab 1 Item"));
        tabLayout.addTab(tabLayout.newTab().setText("Tab 2 Item"));
        tabLayout.addTab(tabLayout.newTab().setText("Tab 3 Item"));
        tabLayout.addTab(tabLayout.newTab().setText(">>"));

        final ViewPager viewPager =
                (ViewPager) findViewById(R.id.viewpager2);
        final PagerAdapter adapter2 = new tabfragmentadapter(getSupportFragmentManager(),tabLayout.getTabCount());

        viewPager.setAdapter(adapter2);
        tabLayout.setupWithViewPager( viewPager );

    }
    }

Адаптер макета вкладок

package com.example.panel_monitoring.activities;

import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;

public class tabfragmentadapter extends FragmentPagerAdapter {

    private String[] tabs = {"<<","Panel 1","Panel 2","Panel 3",">>"};

    int tabCount;

    public tabfragmentadapter(FragmentManager fm,int numberofTabs) {
        super( fm );
        this.tabCount = numberofTabs;
    }

    public CharSequence getPageTitle(int position)
    {
        return tabs[ position ];
    }

    @Override
    public Fragment getItem(int position)
    {
        switch (position) {
            case 0:
                feeder_tab1 tab0 = new feeder_tab1();
                return tab0;
            case 1:
                feeder_tab2 tab1 = new feeder_tab2();
                return tab1;
            case 2:
                act_panel_2 tab2 = new act_panel_2();
                return tab2;
            case 3:
                act_panel_3 tab3 = new act_panel_3();
                return tab3;
            case 4:
                act_panel_4 tab4 = new act_panel_4();
                return tab4;
            default:
                return null  ;
        }
    }



    @Override
    public int getCount() {
        return tabCount;
    }
}
