1、随笔提示在Android之中可以依靠AutoCompleteTextView组件来实现。

在main.xml中

<?xml version="1.0" encoding="utf-8"?>

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

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:orientation="vertical" >

<AutoCompleteTextView

android:id="@+id/myauto"

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:layout_margin="8dp"/>

</LinearLayout>

在MyAutoCompleteTextDemo.java程序中

package com.tarena.autocompletetextview;

import android.app.Activity;

import android.os.Bundle;

import android.widget.ArrayAdapter;

import android.widget.AutoCompleteTextView;

public class MyAutoCompleteTextDemo extends Activity {

private static final String DATA[] = new String[]{"北海银滩",

"北海海底世界","北海涠洲岛","北海冠头岭","北海中山公园"};

private AutoCompleteTextView myauto = null;

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

super.setContentView(R.layout.main);

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

android.R.layout.simple_dropdown_item_1line,DATA);

this.myauto= (AutoCompleteTextView) super.findViewById(R.id.myauto); //取得组件

this.myauto.setAdapter(adapter); //设置内容

}
