Android实现动态自动匹配输入内容

package com.example.myapplication;
 
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.widget.ArrayAdapter;
import android.widget.AutoCompleteTextView;
import android.widget.MultiAutoCompleteTextView;
 
public class MainActivity extends AppCompatActivity {
  //初始化控件
  private AutoCompleteTextView autoCompleteTextView;
  private MultiAutoCompleteTextView multiAutoCompleteTextView;
  //初始化数据源
  private String [] res = {"biejing","nangchang","chengdu","shanghai"};
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    /**
     * AutoCompleteTextView的用法
     */
    autoCompleteTextView = (AutoCompleteTextView) findViewById(R.id.auto_textView);
    //创建适配器
    ArrayAdapter adapter = new ArrayAdapter(this,android.R.layout.simple_list_item_1,res);
    //将adapter与autoCompleteTextView绑定
    autoCompleteTextView.setAdapter(adapter);
 
    /**
     * MultiAutoCompleteTextView的用法
     */
    multiAutoCompleteTextView = (MultiAutoCompleteTextView) findViewById(R.id.mauto_textView);
    //将adapter与multiAutoCompleteTextView绑定
    multiAutoCompleteTextView.setAdapter(adapter);
    //设置以逗号为分隔符结束的符号
    multiAutoCompleteTextView.setTokenizer(new MultiAutoCompleteTextView.CommaTokenizer());
 
  }
}
