使用autoCompleteTextView以及MultiAutoCompleteTextView实现自动匹配输入内容

一:autoCompleteTextView

1:控件属性设置:

     注意添加:android:completionThreshold="1"来设置输入几个字符的时候开始显示匹配的内容

<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"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >
    //completionThreshould 定义输入几个字符的时候开始匹配
    <AutoCompleteTextView
         
        android:completionThreshold="1"
        android:id="@+id/autoCompleteTextView1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:hint="@string/name" >

        <requestFocus />
    </AutoCompleteTextView>

</RelativeLayout>

2:MainActive文件设置

package com.example.demo2;

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

public class MainActivity extends Activity {
    private AutoCompleteTextView acTv;
    private String[] res = {"北京1", "北京2", "北京3", "上海", "上徐", "上海2"};
    @Override
    /*
     * 1: 新建一个适配器 
     * 2: 初始化数据源,用这里的数据源去匹配文本框输入的内容 
     * 3: 将adpter与当前AutoCompleteTextView类的对象绑定 
     * @see android.app.Activity#onCreate(android.os.Bundle)
     */
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //根据id查找AutoCompleteTextView对象
        acTv = (AutoCompleteTextView) findViewById(R.id.autoCompleteTextView1);
        //然后创建一个适配器用于匹配
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                                     android.R.layout.simple_list_item_1, res);
        acTv.setAdapter(adapter);//将adapter这个适配器与AutoCompleteTextView对象(控件)绑定 
    }
    
}

 2:MultiAutoCompleteTextView使用

与AotoCompleteTextView不同的就是他可以在同一个输入框中实现多个匹配

需要多设置一个分隔符,macTextView.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer());

其他同上

主文件:

package com.example.demo2;

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 acTv;
    private MultiAutoCompleteTextView macTextView;
    private String[] res = {"北京1", "北京2", "北京3", "上海", "上徐", "上海2"};
    @Override
    /*
     * 1: 新建一个适配器 
     * 2: 初始化数据源,用这里的数据源去匹配文本框输入的内容 
     * 3: 将adpter与当前AutoCompleteTextView类的对象绑定 
     * @see android.app.Activity#onCreate(android.os.Bundle)
     */
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        //根据id查找AutoCompleteTextView对象
        acTv = (AutoCompleteTextView) findViewById(R.id.autoCompleteTextView1);
        //然后创建一个适配器用于匹配
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
                                     android.R.layout.simple_list_item_1, res);
        acTv.setAdapter(adapter);//将adapter这个适配器与AutoCompleteTextView对象(控件)绑定
        
        macTextView = (MultiAutoCompleteTextView) findViewById(R.id.multiAutoCompleteTextView1);
        //把 MultiAutoCompleteTextView和适配器绑定 
        macTextView.setAdapter(adapter);
        //设置以逗号分隔符为结束的符号 
        macTextView.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer());    
    }
    
}

2:控件属性文件

<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"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >
    //completionThreshould 定义输入几个字符的时候开始匹配
    <AutoCompleteTextView
         
        android:completionThreshold="1"
        android:id="@+id/autoCompleteTextView1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentRight="true"
        android:hint="@string/name" >

        <requestFocus />
    </AutoCompleteTextView>

    <MultiAutoCompleteTextView
        android:completionThreshold="1"
        android:id="@+id/multiAutoCompleteTextView1"
        android:layout_margin="10dp"
        android:layout_below="@id/autoCompleteTextView1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:hint="@string/name" />

</RelativeLayout>
