Android 中 AutoCompleteTextView和MultiAutoCompleteTextView的区别以及用法

举例说明:

anctiity_main.xml文件布局

<?xml version="1.0" encoding="utf-8"?><LinearLayout    xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:app="http://schemas.android.com/apk/res-auto"    xmlns:tools="http://schemas.android.com/tools"    android:layout_width="match_parent"    android:layout_height="match_parent"    tools:context="com.yongninggo.helloworld1.MainActivity"    android:orientation="vertical">    <AutoCompleteTextView        android:id="@+id/autocomplete"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:layout_marginTop="5dip"        android:hint="password"        android:completionThreshold="3"/>    <MultiAutoCompleteTextView        android:id="@+id/complete"        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:hint="username"        android:layout_marginTop="120dip"        android:completionThreshold="3"/></LinearLayout>

MainActivity.Java文件

package com.yongninggo.helloworld1;import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.widget.ArrayAdapter;import android.widget.AutoCompleteTextView;import android.widget.MultiAutoCompleteTextView;public class MainActivity extends AppCompatActivity {    private AutoCompleteTextView autoCompleteTextView;    private MultiAutoCompleteTextView multiAutoCompleteTextView;    private String [] ma = {"12345","123458","12548","12345","147123",};    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        autoCompleteTextView = (AutoCompleteTextView) findViewById(R.id.autocomplete);        multiAutoCompleteTextView = (MultiAutoCompleteTextView) findViewById(R.id.complete);        ArrayAdapter<String> adapter = new ArrayAdapter<String>(                this,                android.R.layout.simple_list_item_1,                ma        );        autoCompleteTextView.setAdapter(adapter);        multiAutoCompleteTextView.setAdapter(adapter);        multiAutoCompleteTextView.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer());    }}
