1.普通listview

<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:orientation="vertical"><ListView      android:layout_width="wrap_content"    android:layout_height="match_parent"    android:entries="@array/books"    android:divider="#f00"    android:dividerHeight="2sp"    android:background="#6E4A90"    android:headerDividersEnabled="false"    /></LinearLayout>
<?xml version="1.0" encoding="utf-8"?><resources>   <string-array name="books">           <item >疯狂英语1</item>          <item >疯狂英语2</item>           <item >疯狂英语3</item>            <item >疯狂英语4</item>         <item >疯狂英语5</item>         </string-array></resources>

可以用xml创建数组。

2.用ArrayAdapter创建listview

<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:orientation="vertical">    <ListView        android:id="@+id/list1"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:divider="#f00"        android:dividerHeight="2sp"        android:headerDividersEnabled="false" /> <ListView        android:id="@+id/list2"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:divider="#0f0"        android:dividerHeight="2sp"        android:headerDividersEnabled="false" />        </LinearLayout>
<?xml version="1.0" encoding="utf-8"?><TextView xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="wrap_content"     android:textSize="24sp"    android:padding="10sp"    android:shadowColor="#f0f"    android:shadowDx="4"    android:shadowDy="4"    android:shadowRadius="2"/>
<?xml version="1.0" encoding="utf-8"?><CheckedTextView xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="wrap_content"     android:textSize="24sp"    android:padding="10sp"    android:checkMark="@drawable/ok"    android:shadowColor="#f0f"    android:shadowDx="4"    android:shadowDy="4"    android:shadowRadius="2" /> 
package com.example.arrayadapter;import android.app.Activity;import android.os.Bundle;import android.widget.ArrayAdapter;import android.widget.ListView;public class MainActivity extends Activity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        ListView list1=(ListView) findViewById(R.id.list1);        String[] arr1={"孙悟空","猪八戒","牛魔王"};        ArrayAdapter<String> adapter1=new ArrayAdapter<String>(this,R.layout.array_item,arr1);        list1.setAdapter(adapter1);        ListView list2=(ListView) findViewById(R.id.list2);        String[] arr2={"java","spring","android"};        ArrayAdapter<String> adapter2=new ArrayAdapter<String>(this,R.layout.checked_item,arr2);        list2.setAdapter(adapter2);    }}

注》疑问，checkMark用法
