下述程序中主要学习 AutoCompleteTextView 的用法，该控件无法在布局文件里指定 android:entries，临时没有查证有没有其它指定的方法，因此决定採用代码载入。还有一个须要注意 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>
