Android自动填充短信验证码 Android实现自动填充短信验证码

短信验证码是大部分软件里面都存在的功能，同时为了避免用户自己输入导致的繁琐操作，有一部分app设计者将其设置成了自动填充的方式，方便用户操作那么这种方式是什么实现的呢。

利用广播接收器来拦截短信获取其中匹配的内容，提供回掉，将短信内容暴露到activity中实现自动填充

首先我们要实现一个广播接收器

package com.wquant.weilt.reciver;

import java.util.regex.Matcher;
import java.util.regex.Pattern;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.os.Message;
import android.telephony.SmsMessage;
import android.text.TextUtils;
import android.util.Log;

public class SmsReciver extends BroadcastReceiver {
 private String patternCoder = "(?<!\\d)\\d{6}(?!\\d)";
 @Override
 public void onReceive(Context context, Intent intent) {
  //获取短信数据
  Object[] objs = (Object[]) intent.getExtras().get("pdus");
  for (Object obj : objs) {
   byte[] pdu = (byte[]) obj;
   //将字节数组封装成为smsmessage对象
   SmsMessage sms = SmsMessage.createFromPdu(pdu);
   //获得短短信内容
   String message = sms.getMessageBody();
   Log.d("短信内容", "message：" + message);
   // 短息的手机号。。+86开头？
   String from = sms.getOriginatingAddress();
   Log.d("短信来源", "from ：" + from);
   if (!TextUtils.isEmpty(from)) {
    String code = patternCode(message);
    if (!TextUtils.isEmpty(code)) {
     mMessageListener.onReceived(code);
    }
   }
  }
 }
 /**
  * 匹配短信中间的6个数字（验证码等）
  * 
  * @param patternContent
  * @return
  */
 private String patternCode(String patternContent) {
  if (TextUtils.isEmpty(patternContent)) {
   return null;
  }
  Pattern p = Pattern.compile(patternCoder);
  Matcher matcher = p.matcher(patternContent);
  if (matcher.find()) {
   return matcher.group();
  }
  return null;
 }

 // 回调接口
 public interface MessageListener {
  public void onReceived(String message);
 }

 MessageListener mMessageListener;

 public void setOnReceivedMessageListener(MessageListener messageListener) {
  this.mMessageListener = messageListener;
 }
}

ok上面我们已经实现了广播接收器，在activity中我们要绑定一个意图过滤器并将此广播注册在destory方法中要将其解除注册

package com.wquant.weilt.controler;

import org.apache.http.Header;
import org.json.JSONException;
import org.json.JSONObject;

import android.content.Intent;
import android.content.IntentFilter;
import android.os.Bundle;
import android.os.CountDownTimer;
import android.view.KeyEvent;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;

import com.loopj.android.http.RequestParams;
import com.wquant.weilt.MyApplication;
import com.wquant.weilt.R;
import com.wquant.weilt.control.base.JsonHttpResponseHandlerBase;
import com.wquant.weilt.control.base.MyBaseActivity;
import com.wquant.weilt.reciver.SmsReciver;
import com.wquant.weilt.reciver.SmsReciver.MessageListener;
import com.wquant.weilt.util.CToast;
import com.wquant.weilt.util.CommonUtil;
import com.wquant.weilt.util.Constant;
import com.wquant.weilt.util.HttpUtil;

/**
 * 修改密码
 * 
 * @author zhaomy
 * 
 */
public class RestartLoginOrTradPwdActivity extends MyBaseActivity {

 SmsReciver reciver;
 @Override
 protected void onCreate(Bundle savedInstanceState) {
  // TODO Auto-generated method stub
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_restart_login_or_trad);

  init();
 }

 private void init() {
  code = (EditText) findViewById(R.id.register_code);
  reciver=new SmsReciver();
  IntentFilter filter = new IntentFilter();
  // 设置短信拦截参数
  filter.addAction("android.provider.Telephony.SMS_RECEIVED");
  //设置最大优先级
  filter.setPriority(Integer.MAX_VALUE);
  registerReceiver(reciver, filter);
  reciver.setOnReceivedMessageListener(new MessageListener() {

   @Override
   public void onReceived(String message) {
    code.setText(message);
   }
  });
 }
 @Override
 protected void onPause() {
  super.onPause();
 }
 @Override
 protected void onDestroy() {
  unregisterReceiver(reciver);
  super.onDestroy();
 }
}
