Android应用中怎么实现一个滑动切换页面功能

<LinearLayout
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:orientation="horizontal"
  >
  <android.support.design.widget.TabLayout
   android:id="@+id/homefragment_tablelayouts"
   android:layout_width="0dp"
   android:layout_height="30dp"
   app:tabIndicatorHeight="2dp"
   android:layout_weight="1"
   app:tabIndicatorColor="@color/colorred"
   app:tabSelectedTextColor="#000000"
   app:tabMode="scrollable"
   >
  </android.support.design.widget.TabLayout>
  <ImageView
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:src="@drawable/add_channel_titlbar_new"
   />
 </LinearLayout>
 <android.support.v4.view.ViewPager
  android:layout_weight="1"
  android:layout_width="match_parent"
  android:layout_height="wrap_content"
  android:id="@+id/homefragment_vp"
  ></android.support.v4.view.ViewPager>

//定义一个方法 
 public void getVpTitleData() {
 // 找到 TabLayou 控件
  TabLayout mTabLayout= (TabLayout) getView().findViewById(R.id.homefragment_tablelayouts);
  // 找到 ViewPager 控件
  ViewPager mViewPager= (ViewPager) getView().findViewById(R.id.homefragment_vp);
  //定义 title 集合 来存储 解析的data数据
  listtitle = new ArrayList<>();
  listtitle .add("头条");
  listtitle .add("社会");
  listtitle .add("国内");
  listtitle .add("国际");
  listtitle .add("明星");
  listtitle .add("娱乐");
  listtitle .add("军事");
  listtitle .add("财经");
  listtitle .add("时尚");
  listtitle .add("八卦");
  //遍历 listtitle 集合 将title 添加经 TabLayou z中
  for (int i = 0; i <listtitle.size() ; i++) {
   mTabLayout.addTab(mTabLayout.newTab().setText(listtitle.get(i)));
  }
  //创建集合 循环添加创建的Fragment
  listfragment = new ArrayList<>();
  for (int i = 0; i <date.size() ; i++) {
   BeiJingFragment mjingFragment = new BeiJingFragment();
   listfragment.add(mjingFragment);
  }
  HomeFragmentVPFragmentAdapter mAdapter = new HomeFragmentVPFragmentAdapter(getFragmentManager(),listfragment,listtitle);
  //给ViewPager设置适配器
  mViewPager.setAdapter(mAdapter);
  //将TabLayout和ViewPager关联起来。
  mTabLayout.setupWithViewPager(mViewPager);
  //给TabLayout设置适配器
  mTabLayout.setTabsFromPagerAdapter(mAdapter);
 }

public class HomeFragmentVPFragmentAdapter extends FragmentStatePagerAdapter {
 List<Fragment> listfragment;
 List<String> listtitle;
 public HomeFragmentVPFragmentAdapter(FragmentManager fm, List<Fragment> listfragment, List<String> listtitle) {
  super(fm);
  this.listfragment = listfragment;
  this.listtitle = listtitle;
 }
 @Override
 public CharSequence getPageTitle(int position) {
  return listtitle.get(position);
 }
 @Override
 public Fragment getItem(int position) {
  return listfragment.get(position);
 }
 @Override
 public int getCount() {
  return listfragment.size();
 }
}
