下述程序中主要学习 AutoCompleteTextView 的使用方法，该控件无法在布局文件中指定 android:entries，暂时没有查证有没有其他指定的方法，因此决定采用代码加载！另一个需要注意 layout 中 <requestFocus /> 的使用。

1.MainActivity.java

package com.sweetlover.activity;import com.sweetlover.autocompletetextviewdemo.R;import android.app.Activity;import android.os.Bundle;import android.widget.ArrayAdapter;import android.widget.AutoCompleteTextView;public class MainActivity extends Activity {		private static final String[] phoneNumber = new String[]{		"111234", "133126", "303404", "796863"	};		private AutoCompleteTextView autoTextView = null;	@Override	protected void onCreate(Bundle savedInstanceState) {		// TODO Auto-generated method stub		super.onCreate(savedInstanceState);		setContentView(R.layout.activity_main);				ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,				android.R.layout.simple_dropdown_item_1line, phoneNumber);		autoTextView = (AutoCompleteTextView)findViewById(R.id.autoCompleteTextView1);		autoTextView.setAdapter(adapter);	}}

2.activity_main.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:padding="30dp"    android:orientation="vertical" >    <AutoCompleteTextView        android:id="@+id/autoCompleteTextView1"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_gravity="center"        android:hint="@string/note"        android:ems="20" >        <requestFocus />        <!-- http://zhangkun716717-126-com.iteye.com/blog/802201 -->    </AutoCompleteTextView></LinearLayout>

3.string.xml

<resources>    <string name="app_name">AutoCompleteTextViewDemo</string>    <string name="note">输入电话号码</string></resources>

4.AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"    package="com.sweetlover.autocompletetextviewdemo"    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.sweetlover.activity.MainActivity">            <intent-filter>                <action android:name="android.intent.action.MAIN"/>                <category android:name="android.intent.category.LAUNCHER"/>            </intent-filter>        </activity>    </application></manifest>
