下述程式中主要學習 AutoCompleteTextView 的使用方法，該控制項無法在布局檔案中指定 android:entries，暫時沒有查證有沒有其他指定的方法，因此決定採用代碼載入！另一個需要注意 layout 中 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;@Overrideprotected void onCreate(Bundle savedInstanceState) {// TODO Auto-generated method stubsuper.onCreate(savedInstanceState);setContentView(R.layout.activity_main);ArrayAdapter adapter = new ArrayAdapter(this,android.R.layout.simple_dropdown_item_1line, phoneNumber);autoTextView = (AutoCompleteTextView)findViewById(R.id.autoCompleteTextView1);autoTextView.setAdapter(adapter);}}

2.activity_main.xml

<!--{cke_protected}{C}%3C!%2D%2D%3Fxml%20version%3D%221.0%22%20encoding%3D%22utf-8%22%3F%2D%2D%3E--><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>        <!--{cke_protected}{C}%3C!%2D%2D%20http%3A%2F%2Fzhangkun716717-126-com.iteye.com%2Fblog%2F802201%20%2D%2D%3E-->    </requestfocus></autocompletetextview></linearlayout>

3.string.xml

<resources>    <string name="app_name">AutoCompleteTextViewDemo</string>    <string name="note">輸入電話號碼</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">            </category></action></intent-filter>        </activity>    </application></uses-sdk></manifest>
