这是我的Java代码

import android.support.design.widget.TabLayout;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.support.v7.widget.Toolbar;
import android.widget.TableLayout;

import com.example.moin.fyp.Activities.Activities.Adapters.ViewPagerAdapter;
import com.example.moin.fyp.Activities.Activities.Fragments.Maps_Fragment;
import com.example.moin.fyp.R;

public class MainActivity extends AppCompatActivity {

    Toolbar toolbar;
    ViewPager viewPager;
    TabLayout tabLayout;

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

        toolbar = (Toolbar) findViewById(R.id.toolbar);
        viewPager = (ViewPager)findViewById(R.id.viewPager);
        tabLayout = (TabLayout)findViewById(R.id.tabLayout);

        setSupportActionBar(toolbar);
        getSupportActionBar().setTitle("Cab Booking App");

        ViewPagerAdapter adapter = new     ViewPagerAdapter(getSupportFragmentManager());
        adapter.addFragemnt(new Maps_Fragment(),"Maps");
        adapter.addFragemnt(new Maps_Fragment(),"Maps");

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

    }
}
