<manifest xmlns:android="http://schemas.android.com/apk/res/android"

    package="com.itheima28.arrayadapterdemo"

    android:versionCode="1"

    android:versionName="1.0" >

 

    <uses-sdk

        android:minSdkVersion="8"

        android:targetSdkVersion="19" />

 

    <application

        android:allowBackup="true"

        android:icon="@drawable/ic_launcher"

        android:label="@string/app_name"

        android:theme="@style/AppTheme" >

        <activity

            android:name="com.itheima28.arrayadapterdemo.MainActivity"

            android:label="@string/app_name" >

            <intent-filter>

                <action android:name="android.intent.action.MAIN" />

 

                <category android:name="android.intent.category.LAUNCHER" />

            </intent-filter>

        </activity>

    </application>

</manifest>

3 编写布局文件activity_main.xml

<RelativeLayout 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.itheima28.arrayadapterdemo.MainActivity$PlaceholderFragment" >

 

    <ListView

        android:id="@+id/listview"

        android:layout_width="match_parent"

        android:layout_height="match_parent"/>

 

</RelativeLayout>

4 编写代码

package com.itheima28.arrayadapterdemo;

 

import android.app.Activity;

import android.os.Bundle;

import android.widget.ArrayAdapter;

import android.widget.ListView;

 

/**

 * ArrayAdapter的使用

 * @author toto

 *

 */

public class MainActivity extends Activity {

 

    @Override

    protected void onCreate(Bundle savedInstanceState) {

       super.onCreate(savedInstanceState);

       setContentView(R.layout.activity_main);

      

       ListView mListView = (ListView) findViewById(R.id.listview);

       String[] textArray = {

"功能1","功能2","功能3","功能4","功能5","功能6","功能7","功能8"};

      

       /**

        * 定义数据适配器

        */

       ArrayAdapter<String> adapter = new ArrayAdapter<String>(

              this,

              android.R.layout.simple_list_item_1,

              textArray);

       mListView.setAdapter(adapter);

    }

}
