[操作系统]Android自动读取短信验证码


实现自动获取手机的短信验证码,原理通过监听短信数据库的变化来解析短信,获取验证码。

直接附上代码:

1.建立一个监听数据库的类

import java.util.regex.Matcher;import java.util.regex.Pattern;import android.app.Activity;import android.database.ContentObserver;import android.database.Cursor;import android.net.Uri;import android.os.Handler;import android.widget.EditText;/** * 监听短信数据库,自动获取短信验证码 * * @author 贾亚光 * @date 2015-3-25 * */public class AutoGetCode extends ContentObserver {  private Cursor cursor = null;  private Activity activity;  private String smsContent = "";  private EditText editText = null;  public AutoGetCode(Activity activity, Handler handler, EditText edittext) {    super(handler);    this.activity = activity;    this.editText = edittext;  }  @Override  public void onChange(boolean selfChange) {    super.onChange(selfChange);    // 读取收件箱中指定号码的短信    cursor = activity.managedQuery(Uri.parse("content://sms/inbox"),        new String[] { "_id", "address", "read", "body" }, "address=? and read=?",        new String[] {"你要截获的电话号码", "0" }, "_id desc");    // 按短信id排序,如果按date排序的话,修改手机时间后,读取的短信就不准了    if (cursor != null && cursor.getCount() > 0) {      cursor.moveToFirst();      if (cursor.moveToFirst()) {        String smsbody = cursor            .getString(cursor.getColumnIndex("body"));        String regEx = "(?<![0-9])([0-9]{" + 6 + "})(?![0-9])";        Pattern p = Pattern.compile(regEx);        Matcher m = p.matcher(smsbody.toString());        while (m.find()) {          smsContent = m.group();          editText.setText(smsContent);        }      }    }  }}

2.在使用的时候在activity中注册

AutoGetCode autoGetCode = new AutoGetCode(RegistCode.this, new Handler(),        regist_code);//regist_code 要显示验证码的EditText    // 注册短信变化监听    this.getContentResolver().registerContentObserver(        Uri.parse("content://sms/"), true, autoGetCode);

3.在合适的地方取消注册

@Override  protected void onDestroy() {    // TODO Auto-generated method stub    super.onDestroy();    this.getContentResolver().unregisterContentObserver(autoGetCode);  }

4.最后别忘记了添加权限

 <!-- 读写短信的权限 -->  <uses-permission android:name="android.permission.RECEIVE_SMS" />  <uses-permission android:name="android.permission.READ_SMS" />  <uses-permission android:name="android.permission.SEND_SMS" />  <uses-permission android:name="android.permission.WRITE_SMS" />

这样就可以了。
