本文介绍了一个类似于Toutiao新闻应用的UI设计与实现过程，包括使用TabLayout和ViewPager进行页面切换，通过Fragment展示不同类别的新闻内容，并实现了侧滑菜单功能。

package com.example.toutiao;

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 com.example.toutiao.Fragment1.MyFragment;
import com.jeremyfeinstein.slidingmenu.lib.SlidingMenu;

/**

public class MyActivity extends AppCompatActivity{

    private TabLayout tab;
    private ViewPager vp;

    private final String[] name = new String[]{"推荐","热点","北京","科技","军事","视频","社会"};

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.myactivity);
        tab = (TabLayout) findViewById(R.id.tab);
        vp = (ViewPager) findViewById(R.id.vp);
        //侧滑
        initMenu();
        //Tab方法
        initTab();


    }
    //Tab方法
    private void initTab() {
        for (String str : name){
            tab.addTab(tab.newTab().setText(str));
        }
        //绑定Viewpager适配器
        vp.setAdapter(new vpada(getSupportFragmentManager()));
        //tab和vp关联
        tab.setupWithViewPager(vp);

    }

    //侧滑
    private void initMenu() {
        SlidingMenu menu = new SlidingMenu(MyActivity.this);
        //左侧滑动
        menu.setMode(SlidingMenu.LEFT);
        //点击滑动区域
        menu.setTouchModeAbove(SlidingMenu.TOUCHMODE_MARGIN);
        //绑定本页面
        menu.attachToActivity(MyActivity.this,SlidingMenu.SLIDING_CONTENT);
        //设置宽
        menu.setBehindOffset(100);
        //绑定布局
        menu.setMenu(R.layout.cehua);
    }

    //viewpager适配器
    class vpada extends FragmentPagerAdapter{

        public vpada(FragmentManager fm) {
            super(fm);
        }

        @Override
        public Fragment getItem(int position) {
            MyFragment my = new MyFragment();
            return my;
        }

        @Override
        public int getCount() {
            return name.length;
        }

        @Override
        public CharSequence getPageTitle(int position) {
            return name[position];
        }
    }
}
