（一）

1.效果图：

2.MainActivity.java

 package com.example.app5;

 import android.support.v7.app.AppCompatActivity;
 import android.os.Bundle;
 import android.widget.ArrayAdapter;
 import android.widget.ListView;

 import java.util.ArrayList;
 import java.util.List;

 public class MainActivity extends AppCompatActivity {
     private ListView listView;
     private List<String> list;
     private ArrayAdapter arrayAdapter;

     @Override
     protected void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.activity_main);

         listView = (ListView) findViewById(R.id.lv);

         //新建数据源
         list = new ArrayList<>();
         for (int i=0;i<20;i++){
             list.add("listview子项"+i);
         }

         //新建适配器，适配器绑定数据
         arrayAdapter = new ArrayAdapter(MainActivity.this,android.R.layout.simple_list_item_1,list);
        /* arrayAdapter=new ArrayAdapter(MainActivity.this,R.layout.item,list);*/    添加自定义的布局

         //视图加载适配器
         listView.setAdapter(arrayAdapter);
     }
 }

3.activity_mian.xml

 <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     xmlns:tools="http://schemas.android.com/tools"
     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="com.example.app5.MainActivity"
     android:orientation="vertical">

     <ListView
         android:id="@+id/lv"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content" />
 </LinearLayout>

4.自定义的布局item.xml

 <?xml version="1.0" encoding="utf-8"?>
 <TextView
     android:id="@+id/tv"
     android:textColor="@color/colorAccent"
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     xmlns:android="http://schemas.android.com/apk/res/android" />
