如何将选项卡式活动转换为片段？

Question

我有一个选项卡式活动，单击底部导航视图按钮时需要显示，我需要将其转换为片段式

公共类MainActivityTabs扩展了AppCompatActivity {

private SectionsPagerAdapter mSectionsPagerAdapter;

private ViewPager mViewPager;

Fragment homeFragment;
Fragment searchFragment;
Fragment cameraFragment;
Fragment favoritesFragment;
Fragment profileFragment;

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

    mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());

    mViewPager = (ViewPager) findViewById(R.id.container);
    mViewPager.setAdapter(mSectionsPagerAdapter);

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

    mViewPager.addOnPageChangeListener(new TabLayout.TabLayoutOnPageChangeListener(tabLayout));
    tabLayout.addOnTabSelectedListener(new TabLayout.ViewPagerOnTabSelectedListener(mViewPager));

    homeFragment = new HomeFragment();
    searchFragment = new SearchFragment();
    cameraFragment = new CameraFragment();
    favoritesFragment = new FavoritesFragment();
    profileFragment = new ProfileFragment();

}

public class SectionsPagerAdapter extends FragmentPagerAdapter {

    public SectionsPagerAdapter(FragmentManager fm) {
        super(fm);
    }

    @Override
    public Fragment getItem(int position) {
        if (position == 0) {
            return homeFragment;
        } else if (position == 1) {
            return searchFragment;
        } else if (position == 2) {
            return cameraFragment;
        } else if (position == 3) {
            return favoritesFragment;
        } else if (position == 4) {
            return profileFragment;
        }
        return null;
    }

    @Override
    public int getCount() {
        return 5;
    }
}

}

我需要使活动仅在单击底部导航视图中的按钮时出现。
