TabLayout+Viewpager+Fragment实现分页滚动

效果如上，顶部标签滚动底下的页面也跟着滚动 灰色的标签只是一个recyclerview装起来的

这里用TabLayout+Viewpager+Fragment实现

先看布局

<RelativeLayout 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:background="#f1f1f1"
                android:orientation="vertical">

    <RelativeLayout
        android:id="@+id/rl_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true">

        <include layout="@layout/titlebar"/>
    RelativeLayout>

    <LinearLayout
        android:id="@+id/ll_tab"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@+id/rl_title"
        android:background="@color/white"
        android:orientation="horizontal">

        <android.support.design.widget.TabLayout
            android:id="@+id/tab_layout"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            android:layout_marginLeft="15dp"
            android:layout_weight="1"
            android:minHeight="45dp"
            app:tabMode="scrollable"
            app:tabIndicatorColor="@color/main_blue"
            app:tabSelectedTextColor="@android:color/black"
            app:tabTextAppearance="@style/TabLayoutTextStyle"
            app:tabTextColor="@android:color/darker_gray"/>

        <ImageView
            android:id="@+id/menu"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_vertical"
            android:layout_marginRight="15dp"
            android:src="@mipmap/icon_black_limit"/>

    LinearLayout>


    <EditText
        android:id="@+id/et_search"
        android:layout_below="@+id/ll_tab"
        android:background="@drawable/shape_rec_white_bg"
        android:hint="请输入关键字搜索"
        android:paddingLeft="8dp"
        android:textSize="14sp"
        android:gravity="center_vertical"
        android:paddingRight="8dp"
        android:drawableRight="@drawable/search"
        android:layout_marginTop="15dp"
        android:layout_marginLeft="15dp"
        android:layout_marginRight="15dp"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:minHeight="45dp"/>

    <android.support.v4.view.ViewPager
        android:id="@+id/view_pager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@+id/et_search"
        android:layout_marginTop="1dp"/>
    <TextView
        android:layout_below="@+id/ll_tab"
        android:background="#f1f1f1"
        android:layout_width="match_parent"
        android:layout_height="1dp"/>
    <LinearLayout
        android:layout_below="@+id/ll_tab"
        android:orientation="vertical"
        android:layout_marginTop="1dp"
        android:id="@+id/ll_menu"
        android:visibility="gone"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
        <android.support.v7.widget.RecyclerView
            android:id="@+id/rv"
            android:background="@color/white"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_below="@+id/ll_tab"
            android:paddingBottom="15dp"
            android:layout_centerHorizontal="true"
            >
        android.support.v7.widget.RecyclerView>
        <TextView
            android:background="#b8000000"
            android:layout_width="match_parent"
            android:layout_height="match_parent"/>

    LinearLayout>


RelativeLayout>

然后看看适配器怎么写

import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;

import com.fjrcloud.fuqing.model.local.ArticleClassify;

import java.util.ArrayList;
import java.util.List;

/**
 * Created by Liberation on 2017/10/26.
 */

public class LessonPageAdapter extends FragmentPagerAdapter {
    List titleList;
    private ArrayList fragmentList;

    public LessonPageAdapter(FragmentManager fm, List titleList, ArrayList fragmentList) {
        super(fm);
        this.titleList = titleList;
        this.fragmentList = fragmentList;
    }

    @Override
    public Fragment getItem(int position) {
        return fragmentList.get(position);
    }

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

    @Override
    public CharSequence getPageTitle(int position) {
        return titleList.get(position).getTw_type_title();
    }


}

再看看activity中怎么将tablayout绑定viewpager快下班了偷懒啦

import android.support.v4.view.ViewPager;

import android.widget.PopupWindow;
import android.widget.RelativeLayout;
