Listview和Adapter作业

安卓作业：使用ListView和自定义Adapter完成列表信息显示

1.XML主布局文件代码

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools"    android:id="@+id/activity_main"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:paddingBottom="@dimen/activity_vertical_margin"    android:paddingLeft="@dimen/activity_horizontal_margin"    android:paddingRight="@dimen/activity_horizontal_margin"    android:paddingTop="@dimen/activity_vertical_margin"    tools:context="cn.edu.niit.liebiaoxinxixianshi.QiuActivity">

<LinearLayout        android:layout_width="match_parent"        android:layout_height="match_parent"        android:orientation="vertical"        android:id="@+id/out"        >

</LinearLayout>

</RelativeLayout>2.四个TextView布局：<ListView  android:layout_width="match_parent" android:layout_height="match_parent"  android:id="@+id/list" android:scrollbars="vertical"/> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical"> <TextView  android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/List1" android:text="@string/name"/> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:id="@+id/List2" android:text="@string/age"/> <TextView android:layout_width="wrap_content"  android:layout_height="wrap_content" android:id="@+id/List3" android:text="@string/mail"/> <TextView android:layout_width="wrap_content"  android:layout_height="wrap_content"  android:id="@+id/List4" android:text="@string/address"/>3.定义String<resources>

    <string name="app_name">liebiaoxinxixianshi</string>    <string name="list">目录</string>    <string name="name">姓名</string>    <string name="age">年龄</string>    <string name="mail">邮箱</string></resources>4.java文件package com.example.ershiqiapplication;

import android.app.Fragment; import android.app.FragmentTransaction; import android.support.v7.app.AppCompatActivity; import android.os.Bundle;

public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) {  super.onCreate(savedInstanceState);  setContentView(R.layout.activity_main); FragmentTransaction transaction = getFragmentManager().beginTransaction(); Fragment fragment=new ListViewFragment(); transaction.add(R.id.out,fragment); transaction.commit();//显示fragment } }

增加数据，数据准备：datas.add(new Classinfo("姓名：蔡志坤","年龄：25","邮箱：[email protected]","地址：厦门市")); datas.add(new Classinfo("姓名：李杰华","年龄：25","邮箱：[email protected]","地址：漳州市")); datas.add(new Classinfo("姓名：张亮","年龄：25","邮箱：[email protected]","地址：厦门市"));datas.add(new Classinfo("姓名：陈旭","年龄：25","邮箱：[email protected]","地址：厦门市")); datas.add(new Classinfo("姓名：刘玄德","年龄：25","邮箱：[email protected]","地址：福州市"));自定义Adapter 通过Adapter来获得数据
