Android实现动态自动匹配输入的内容

本文实例为大家分享了Android实现动态自动匹配输入内容的具体代码，供大家参考，具体内容如下

用这两个控件

分别实现这两个：

package com.example.autocomplete;

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

public class MainActivity extends Activity {
 private AutoCompleteTextView acTextView;
 private String[] res = {"xxz1","xxz2","xxz3","shanghai1","shanghai2"};

 private MultiAutoCompleteTextView MulacTextView;
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    acTextView = (AutoCompleteTextView) findViewById(R.id.autoCompleteTextView1);

    //需要适配器
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,res);
    //初始数据源，去匹配文本框中输入的内容,然后绑定
    acTextView.setAdapter(adapter);

    MulacTextView = (MultiAutoCompleteTextView) findViewById(R.id.multiAutoCompleteTextView1);
    MulacTextView.setAdapter(adapter);
    //设置以逗号为分隔符结束的符号
    MulacTextView.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer());

}

布局文件：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:orientation="vertical" >

  <AutoCompleteTextView
    android:hint="请输入搜索的关键词"
    android:completionThreshold="3"
    android:id="@+id/autoCompleteTextView1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
     >

  </AutoCompleteTextView>

  <MultiAutoCompleteTextView
    android:hint="请输入搜索的邮件关键词"
    android:id="@+id/multiAutoCompleteTextView1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" >

  </MultiAutoCompleteTextView>

  <CheckBox
    android:id="@+id/checkBox1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="CheckBox" />

</LinearLayout>
