使用TabLayout的时候我们需要在gradle文件中添加依赖：

compile'com.android.support:design:26+'

主界面：

import android.os.Bundle;import android.support.design.widget.TabLayout;import android.support.v4.app.Fragment;import android.support.v4.app.FragmentPagerAdapter;import android.support.v4.view.ViewPager;import android.support.v7.app.AppCompatActivity;import java.util.ArrayList;import java.util.List;public class MainActivity extends AppCompatActivity {    private TabLayout tabLayout;    private ViewPager viewPager;    private List<String> list;    private List<Fragment> fragmentList;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        tabLayout = (TabLayout) findViewById(R.id.tablayout);        viewPager = (ViewPager) findViewById(R.id.viewpager);        list = new ArrayList<>();        fragmentList = new ArrayList<>();        initData();        viewPager.setAdapter(new FragmentPagerAdapter(getSupportFragmentManager()) {            @Override            public Fragment getItem(int position) {                return fragmentList.get(position);            }            @Override            public int getCount() {                return fragmentList.size();            }            @Override            public CharSequence getPageTitle(int position) {                return list.get(position);            }        });        tabLayout.setTabMode(TabLayout.MODE_FIXED);        tabLayout.setupWithViewPager(viewPager);    }        private void initData() {            for (int i = 0; i < 5; i++) {            fragmentList.add(new BlankFragment());            list.add("我的"+i);        }    }}

Fragment:

public class BlankFragment extends Fragment {    @Nullable    @Override    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {        TextView textView = new TextView(getActivity());        double random = Math.random();        textView.setText("xxxxxxxx" + random);        return textView;    }}

布局：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:app="http://schemas.android.com/apk/res-auto"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:orientation="vertical"    tools:context="com.bwie.tablayoutdemo.MainActivity">    <android.support.design.widget.TabLayout        android:id="@+id/tablayout"        android:layout_width="match_parent"        android:layout_height="wrap_content" />    <android.support.v4.view.ViewPager        android:id="@+id/viewpager"        android:layout_width="match_parent"        android:layout_height="0dp"        android:layout_weight="1" /></LinearLayout>
