下述程序中主要學習 AutoCompleteTextView 的使用方法，該控件無法在布局文件中指定 android:entries，暫時沒有查證有沒有其他指定的方法，因此決定采用代碼加載！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;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.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

        <requestfocus>

    </requestfocus></autocompletetextview>

</linearlayout>

    <string name="note">輸入電話號碼</string>
