如何使MultiAutoCompleteTextView搜索子字符串

Question

我如何使我的MultiAutoCompleteTextView在每个列表位置的字符串内搜索（也搜索子字符串）。我是否需要设置任何属性，甚至有可能？例如，如果列表对象之一是“ abc123”，那么是否可以通过键入123将其包括在自动完成建议中？

MultiAutoCompleteTextView是可编辑的文本视图，扩展了AutoCompleteTextView，可以显示有关用户正在键入而不是必须输入的文本的子字符串对于整个事情。

您必须提供一个MultiAutoCompleteTextView.Tokenizer来区分各种子字符串。

main.xml：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >
<TextView  
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:text="@string/hello"
    />
<MultiAutoCompleteTextView android:id="@+id/multiautocompletetextview"
 android:layout_width="fill_parent"
 android:layout_height="wrap_content"
 android:completionThreshold="1"
 />

Java主要代码：

package com.exercise.AndroidMultiAutoCompleteTextView;

import android.app.Activity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.MultiAutoCompleteTextView;

public class AndroidMultiAutoCompleteTextView extends Activity {

 MultiAutoCompleteTextView myMultiAutoCompleteTextView;
 String item[]={
   "January", "February", "March", "April",
   "May", "June", "July", "August",
   "September", "October", "November", "December"
 };

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        MultiAutoCompleteTextView myMultiAutoCompleteTextView 
         = (MultiAutoCompleteTextView)findViewById(
           R.id.multiautocompletetextview);

        myMultiAutoCompleteTextView.setAdapter(
          new ArrayAdapter<String>(this, 
            android.R.layout.simple_dropdown_item_1line, item));
        myMultiAutoCompleteTextView.setTokenizer(
          new MultiAutoCompleteTextView.CommaTokenizer());

    }
}
