当AutoCompleteTextView和MultiAutoCompleteTextView控件同时存在于一个页面上时，运行程序时，在自己的手机上没有出现提示安装的信息，是什么原因？（该程序运行没有提示错误）

package com.example.mook.kongjian;

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

/**

public class MainActivity extends Activity {
private AutoCompleteTextView atCompleteTextView;
private String[] res = {"LAKERSKB", "LAKERSMJ", "LAKERWC", "SUNS"};
private String[] res1 = {"LAKERSSO", "LAKERSJW", "SUPERS"};
private MultiAutoCompleteTextView macTextView;

protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

atCompleteTextView = (AutoCompleteTextView) findViewById(R.id.autoCompleteTextView1);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, res);
atCompleteTextView.setAdapter(adapter);

macTextView = (MultiAutoCompleteTextView) findViewById(R.id.multiAutoCompleteTextView);
ArrayAdapter<String> adapter1 = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, res1);
macTextView.setAdapter(adapter1);
macTextView.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer());

}
}
