A11_AutoCompleteTextView的设置

1.实现AutoCompleteTextView的基本显示效果

效果：

list_items.xml:

<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="vertical" >

    <TextView
        android:id="@+id/list_items_textViewId"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:padding="10dp"
        android:textSize="15sp"
        android:lines="1"/>

</LinearLayout>

activity_main.xml:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity" >

    <TextView
        android:id="@+id/textViewId"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="单词：" />
    
    <AutoCompleteTextView 
        android:id="@+id/autoCompleteTextViewId"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:hint="请输入……"
        android:layout_toRightOf="@id/textViewId"
        />
</RelativeLayout>

MainActivity.java:

package com.haut.a11_autocompletetextview;

import java.util.ArrayList;
import java.util.List;

import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
import android.widget.ArrayAdapter;
import android.widget.AutoCompleteTextView;

public class MainActivity extends Activity {
	private AutoCompleteTextView autoComplete;

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.activity_main);
		autoComplete = (AutoCompleteTextView) findViewById(R.id.autoCompleteTextViewId);
		// 创建一个容器存储数据
		List<String> list = new ArrayList<String>();
		list.add("above");
		list.add("add");
		list.add("allow");
		list.add("aptment");
		list.add("alone");

		// 也可以用一个数组为适配器提供数据
		String[] data = new String[] { "张一一", "张一二", "张一三", "张一思", "张一武", "张一六" };

		// 创建ArrayAdapter，这里的data可以换成list，都是存放数据的容器
		ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this,
				R.layout.list_items, R.id.list_items_textViewId, data);
		autoComplete.setAdapter(arrayAdapter);

	}
