1.效果图：

2.MainActivity.java

 1 package com.example.app5;
 2 
 3 import android.support.v7.app.AppCompatActivity;
 4 import android.os.Bundle;
 5 import android.widget.ArrayAdapter;
 6 import android.widget.ListView;
 7 
 8 import java.util.ArrayList;
 9 import java.util.List;
10 
11 public class MainActivity extends AppCompatActivity {
12     private ListView listView;
13     private List<String> list;
14     private ArrayAdapter arrayAdapter;
15 
16     @Override
17     protected void onCreate(Bundle savedInstanceState) {
18         super.onCreate(savedInstanceState);
19         setContentView(R.layout.activity_main);
20 
21         listView = (ListView) findViewById(R.id.lv);
22 
23 
24         //新建数据源
25         list = new ArrayList<>();
26         for (int i=0;i<20;i++){
27             list.add("listview子项"+i);
28         }
29 
30         //新建适配器，适配器绑定数据
31         arrayAdapter = new ArrayAdapter(MainActivity.this,android.R.layout.simple_list_item_1,list);
32        /* arrayAdapter=new ArrayAdapter(MainActivity.this,R.layout.item,list);*/    添加自定义的布局
33 
34         //视图加载适配器
35         listView.setAdapter(arrayAdapter);
36     }
37 }
