大家需要创建5个fragment，还有对应的xml文件，这里我给大家展示我创建的MyFragment4.java：

package com.example.xh.twostylefragment; import android.os.Bundle; import android.support.v4.app.Fragment; import android.view.LayoutInflater; import android.view.View; import android.view.ViewGroup; /** * Created by Administrator on 2016/7/8. */public class MyFragment4 extends Fragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = LayoutInflater.from(getActivity()).inflate(R.layout.shoppingcar,container,false);//用view保存shoppingcar.xml布局，大家可以 return view; //自己创建一个xml. } } |
差不多就是这样的了，有问题大家可以提出来。
以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持服务器之家。
