TabLayout和Viewpager配合使用

首先要导个依赖包这个包属于TabLayout ：

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

下面代码是在，XML里的：

<?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"    xmlns:tools="http://schemas.android.com/tools"    android:orientation="vertical"    android:layout_width="match_parent"    android:layout_height="match_parent"    tools:context="zhaochuang.bawei.com.day_rikao.MainActivity"> <android.support.design.widget.TabLayout     android:layout_width="match_parent"     android:layout_height="wrap_content"     android:id="@+id/tab"     ></android.support.design.widget.TabLayout>    <android.support.v4.view.ViewPager        android:layout_width="match_parent"        android:layout_height="0dp"        android:layout_weight="1"        android:id="@+id/vp"        ></android.support.v4.view.ViewPager></LinearLayout>下面代码是一个Fragment的普通方法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("xxxxxxxxxxx"+random);        return textView;    }然后在MianActivity调用了上面这些个方法，如一下代码package com.bwie.tablayoutdemo2;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 java.util.ArrayList;/** * 1--tablayout * 2--- viewPager * 3--viewPagerAdapter * 4-- 让TabLayout和Viewpager关联; */public class MainActivity extends AppCompatActivity {    private TabLayout tabLayout;    private ViewPager viewPager;    ArrayList<Fragment> fragmentList = new ArrayList<Fragment>();    ArrayList<String> titleList = new ArrayList<String>();    @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);        initData();        //ctrl+p 提示参数的快捷键        MPagerAdapter mPagerAdapter = new MPagerAdapter(getSupportFragmentManager());        viewPager.setAdapter(mPagerAdapter);        //设置TabLayout的模式        tabLayout.setTabMode(TabLayout.MODE_FIXED);        //让tablayout和Viewpager关联;        tabLayout.setupWithViewPager(viewPager);    }    private void initData() {        for (int i = 0; i <4 ; i++) {            fragmentList.add(new BlankFragment());            titleList.add("爱因斯坦" +i);        }    }    class  MPagerAdapter extends FragmentPagerAdapter{        public MPagerAdapter(FragmentManager fm) {            super(fm);        }        @Override        public Fragment getItem(int position) {            return fragmentList.get(position);        }        @Override        public int getCount() {            return fragmentList.size();        }        //需要重写个返回标题的方法;        @Override        public CharSequence getPageTitle(int position) {            return titleList.get(position);        }    }}
