TabLayout的基本使用

1.添加依赖：

compile 'com.android.support:appcompat-v7:23.4.0'

compile 'com.android.support:design:24.2.0'

Mianactivity中的使用

package com.noonecode.tablayoutdemo;

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.os.Bundle;

import java.util.ArrayList;import java.util.List;public class MainActivity extends AppCompatActivity {

private TabLayout tabLayout;

private ViewPager viewPager;

private List<Fragment> list;

private MyAdapter adapter;

private String[] titles = {"页面1", "页面2", "页面3"};

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

//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 Tab1Fragment());

list.add(new Tab2Fragment());

list.add(new Tab3Fragment());

//ViewPager的适配器

adapter = new MyAdapter(getSupportFragmentManager());

viewPager.setAdapter(adapter);

//绑定

tabLayout.setupWithViewPager(viewPager);

}

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]; } }}
