Tablayout和Viewpager的结合使用，实现导航的效果

viewpager和Indicator的结合用了一段时间，感觉有点麻烦，所以就尝试使用tablayout
1、先上代码吧，之后再详细解释
2、布局文件

<?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">

    <android.support.design.widget.TabLayout
        android:id="@+id/tabs"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:tabIndicatorColor="@color/red"
        app:tabSelectedTextColor="@color/red" />

    <!--可滑动的布局内容-->
    <android.support.v4.view.ViewPager
        android:id="@+id/vp_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />
</LinearLayout>

3、MainActivity中的代码

package com.huawei.viewpager;

import android.os.Bundle;
import android.support.design.widget.TabLayout;
import android.support.v4.view.PagerAdapter;
import android.support.v4.view.ViewPager;
import android.support.v7.app.AppCompatActivity;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

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

public class MainActivity extends AppCompatActivity {

    private ViewPager mViewPager;

    private LayoutInflater mInflater;
    private List<String> mTitleList = new ArrayList<>();//页卡标题集合
    private View view1, view2, view3, view4, view5;//页卡视图
    private List<View> mViewList = new ArrayList<>();//页卡视图集合
    private TabLayout mTabLayout;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mViewPager = (ViewPager) findViewById(R.id.vp_view);
        mTabLayout = (TabLayout) findViewById(R.id.tabs);
        mInflater = LayoutInflater.from(this);
        view1 = mInflater.inflate(R.layout.activity_main, null);
        view2 = mInflater.inflate(R.layout.activity_main, null);
        view3 = mInflater.inflate(R.layout.activity_main, null);
        view4 = mInflater.inflate(R.layout.activity_main, null);
        view5 = mInflater.inflate(R.layout.activity_main, null);


        mViewList.add(view1);
        mViewList.add(view2);
        mViewList.add(view3);
        mViewList.add(view4);
        mViewList.add(view5);


        mTitleList.add("No:1");
        mTitleList.add("No:2");
        mTitleList.add("No:3");
        mTitleList.add("No:4");
        mTitleList.add("No:5");



        mTabLayout.addTab(mTabLayout.newTab().setText(mTitleList.get(0)));//添加tab选项卡
        mTabLayout.addTab(mTabLayout.newTab().setText(mTitleList.get(1)));
        mTabLayout.addTab(mTabLayout.newTab().setText(mTitleList.get(2)));
        mTabLayout.addTab(mTabLayout.newTab().setText(mTitleList.get(3)));
        mTabLayout.addTab(mTabLayout.newTab().setText(mTitleList.get(4)));
        mTabLayout.setTabMode(TabLayout.MODE_FIXED);//设置tab模式，当前为系统默认模式

        MyPagerAdapter mAdapter = new MyPagerAdapter(mViewList);
        mViewPager.setAdapter(mAdapter);//给ViewPager设置适配器
        mTabLayout.setupWithViewPager(mViewPager);//将TabLayout和ViewPager关联起来。
        //mTabLayout.setTabsFromPagerAdapter(mAdapter);//给Tabs设置适配器
    }


    //ViewPager适配器
    class MyPagerAdapter extends PagerAdapter {
        private List<View> mViewList;

        public MyPagerAdapter(List<View> mViewList) {
            this.mViewList = mViewList;
        }

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

        @Override
        public boolean isViewFromObject(View view, Object object) {
            return view == object;
        }

        @Override
        public Object instantiateItem(ViewGroup container, int position) {
            container.addView(mViewList.get(position));//添加页卡
            return mViewList.get(position);
        }

        @Override
        public void destroyItem(ViewGroup container, int position, Object object) {
            container.removeView(mViewList.get(position));
        }

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

    }
}
