实现一个标签类似的功能很简单，下面功能清楚的注释了一下，有助与你的理解，有了它实现标签功能的具体修改都能是实现，好的代码都和大家分享，喜欢的记得关注呀！！！

下边是我实现的效果图，怎么样，不错吧

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="40dp"
        android:background="@color/gray"
        >

        <android.support.design.widget.TabLayout
            android:id="@+id/tablayout"
            android:layout_width="100dp"
            android:layout_height="30dp"
            android:layout_gravity="center_vertical"
            app:tabTextAppearance="@style/MyTabLayoutTextAppearance"

            />

    </LinearLayout>

    <android.support.v4.view.ViewPager
        android:id="@+id/viewpager"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:isScrollContainer="true"></android.support.v4.view.ViewPager>
</LinearLayout>

下面是主要实现代码：

import android.annotation.SuppressLint;
import android.content.res.Resources;
import android.graphics.Color;
import android.os.Bundle;
import android.support.design.widget.TabLayout;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.util.TypedValue;
import android.view.View;
import android.widget.LinearLayout;
import com.lhss.mw.myapplication.R;
import com.lhss.mw.myapplication.ui.Mime.MinePage.Fragment.Fragment_fenxi;
import com.lhss.mw.myapplication.ui.Mime.MinePage.Fragment.Fragment_zonghe;
import java.lang.reflect.Field;
import java.util.ArrayList;
import java.util.List;

public class PostActivityNew extends AppCompatActivity {
    private TabLayout tabLayout;
    private ViewPager viewPager;

    private List<Fragment> list;
    private MyAdapter adapter;
    private String[] titles = {"综合", "分析"};
    @SuppressLint("ResourceAsColor")
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_postnew);

        //实例化
        viewPager = (ViewPager) findViewById(R.id.viewpager);
        tabLayout = (TabLayout) findViewById(R.id.tablayout);
        //页面，数据源
        list = new ArrayList<>();
        list.add(new Fragment_zonghe());
        list.add(new Fragment_fenxi());
        //ViewPager的适配器
        adapter = new MyAdapter(getSupportFragmentManager());
        viewPager.setAdapter(adapter);
        //绑定
        tabLayout.setupWithViewPager(viewPager);
        //设置默认颜色和选中颜色
        tabLayout.setTabTextColors(Color.BLACK,getResources().getColor(R.color.gold));
        //设置下滑线颜色
        tabLayout.setSelectedTabIndicatorColor(getResources().getColor(R.color.gold));
        //设置下划线的长度
        setIndicator(tabLayout,15,15);
    }

    //设置分割线距离
    public void setIndicator(TabLayout tabs, int leftDip, int rightDip) {
        Class<?> tabLayout = tabs.getClass();
        Field tabStrip = null;
        try {
            tabStrip = tabLayout.getDeclaredField("mTabStrip");
        } catch (NoSuchFieldException e) {
            e.printStackTrace();
        }

        tabStrip.setAccessible(true);
        LinearLayout llTab = null;
        try {
            llTab = (LinearLayout) tabStrip.get(tabs);
        } catch (IllegalAccessException e) {
            e.printStackTrace();
        }

        int left = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, leftDip, Resources.getSystem().getDisplayMetrics());
        int right = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, rightDip, Resources.getSystem().getDisplayMetrics());

        for (int i = 0; i < llTab.getChildCount(); i++) {
            View child = llTab.getChildAt(i);
            child.setPadding(0, 0, 0, 0);
            LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(0, LinearLayout.LayoutParams.MATCH_PARENT, 1);
            params.leftMargin = left;
            params.rightMargin = right;
            child.setLayoutParams(params);
            child.invalidate();
        }
    }



    class MyAdapter extends FragmentPagerAdapter {

        public MyAdapter(FragmentManager fm) {
            super(fm);
        }
        @Override
        public Fragment getItem(int position) {
            return list.get(position);
        }

        @Override
        public int getCount() {
            return list.size();
        }

        //重写这个方法，将设置每个Tab的标题
        @Override
        public CharSequence getPageTitle(int position) {
            return titles[position];
        }
    }
}

下边给大家推荐一个工具类，如果不想让viewpage滑动，就可以用这个工具类

import android.content.Context;
import android.support.v4.view.ViewPager;
import android.util.AttributeSet;
import android.view.MotionEvent;

public class NoScrollViewPager extends ViewPager {
    //true  是不可滑动    false  是可滑动
    private boolean noScroll = true;

    public NoScrollViewPager(Context context, AttributeSet attrs) {
        super(context, attrs);
        // TODO Auto-generated constructor stub
    }

    public NoScrollViewPager(Context context) {
        super(context);
    }

    public void setNoScroll(boolean noScroll) {
        this.noScroll = noScroll;
    }

    @Override
    public void scrollTo(int x, int y) {
        super.scrollTo(x, y);
    }

    @Override
    public boolean onTouchEvent(MotionEvent arg0) {
        /* return false;//super.onTouchEvent(arg0); */
        if (noScroll)
            return false;
        else
            return super.onTouchEvent(arg0);
    }

    @Override
    public boolean onInterceptTouchEvent(MotionEvent arg0) {
        if (noScroll)
            return false;
        else
            return super.onInterceptTouchEvent(arg0);
    }

    @Override
    public void setCurrentItem(int item, boolean smoothScroll) {
        super.setCurrentItem(item, smoothScroll);
    }

    @Override
    public void setCurrentItem(int item) {
        super.setCurrentItem(item);
    }

}
