AutoCompleteTextView是实现动态匹配输入内容的一种输入框(EditText)
如输入“and”时,会提示“android”
- package com.conowen.test;
- import android.app.Activity;
- import android.os.Bundle;
- import android.text.Editable;
- import android.text.TextWatcher;
- import android.widget.AutoCompleteTextView;
- public class DrComActivity extends Activity {
- /** Called when the activity is first created. */
- @Override
- public void onCreate(Bundle savedInstanceState) {
- super.onCreate(savedInstanceState);
- setContentView(R.layout.main);
- AutoCompleteTextView autoinput =(AutoCompleteTextView) findViewById(R.id.autoinput);
- autoinput.setThreshold(1);// 输入一个字母就开始自动提示
- autoinput.addTextChangedListener(new TextWatcher() {
- @Override
- public void onTextChanged(CharSequence s, int start, int before, int count) {
- // TODO Auto-generated method stub
- //s是输入框正在输的字符串,随着不断的输入,s的值也会不停地改变
- String str = s.toString();
- String[] temp = getInputAdapter(getInputWorldOrder(str));
- //此处代码省略,自己通过查询数据库或者其他方法,动态地获取相应的字符串数组
- //如做一个字典时,不可能预先把所有单词做成一个adapter,应该根据输入的字符,
- //动态地查询一定数量的相对应的单词,然后再构建adapter
- ArrayAdapter<String> adapter = new ArrayAdapter<String>(ct,
- android.R.layout.simple_dropdown_item_1line, temp);
- autoinput.setAdapter(adapter)
- //正在输入时,构建adapter,然后把adapter绑定在AutoCompleteTextView 上面
- @Override
- public void beforeTextChanged(CharSequence s, int start, int count,
- int after) {
- // TODO Auto-generated method stub
- }
- @Override
- public void afterTextChanged(Editable s) {
- // TODO Auto-generated method stub
- }
- }
- }
- }
