Android实现获取短信验证码并自动填写功能

本文实例为大家分享了android短信验证码获取并自动填写功能的具体代码，供大家参考，具体内容如下

代码如下：

mainactivity

public class mainactivity extends appcompatactivity {

 public static textview mtext;
 private smscontent content;

 @override
 protected void oncreate(bundle savedinstancestate) {
  super.oncreate(savedinstancestate);
  setcontentview(r.layout.activity_main);

  if (this.checkselfpermission(manifest.permission.read_sms)
    != packagemanager.permission_granted) {
   //申请read_sms权限
   activitycompat.requestpermissions(this,new string[]{manifest.permission.read_sms}, 1);
  }

  mtext = (textview) findviewbyid(r.id.text);

  content = new smscontent(new handler(),this);
    //注册短信变化监听
    this.getcontentresolver().registercontentobserver(uri.parse("content://sms/"), true, content);
 }

 @override
 protected void ondestroy() {
  super.ondestroy();

  this.getcontentresolver().unregistercontentobserver(content);
 }

 @override
 public void onrequestpermissionsresult(int requestcode, @nonnull string[] permissions, @nonnull int[] grantresults) {
  super.onrequestpermissionsresult(requestcode, permissions, grantresults);
  donext(requestcode,grantresults);
 }

 private void donext(int requestcode, int[] grantresults) {
  if (requestcode == 1) {
   if (grantresults[0] == packagemanager.permission_granted) {

   } else {
    // permission denied
   }
  }
 }
}

smscontent

class smscontent extends contentobserver {

 private cursor cursor = null;
 private context context;

 public smscontent(handler handler,context context) {
  super(handler);

  this.context = context;
 }

 @override
 public void onchange(boolean selfchange) {

  super.onchange(selfchange);

  log.i("smstest","begin");

  //读取收件箱中指定号码的短信
//  cursor = context.getcontentresolver().query(uri.parse("content://sms/inbox"), new string[]{"_id", "address", "read", "body"},
//    " address=? and read=?", new string[]{"10086", "0"}, "_id desc");//按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

  cursor = context.getcontentresolver().query(uri.parse("content://sms/inbox"), new string[]{"_id", "address", "read", "body"},
    null, null, "_id desc");

  log.i("smstest","cursor.isbeforefirst(): " + cursor.isbeforefirst() + " cursor.getcount(): " + cursor.getcount());
  if (cursor != null && cursor.getcount() > 0) {

   cursor.movetofirst();
   int smsbodycolumn = cursor.getcolumnindex("body");
   string smsbody = cursor.getstring(smsbodycolumn);
   log.i("smstest","smsbody = " + smsbody);

   mainactivity.mtext.settext(getdynamicpassword(smsbody));
  }

  //在用managedquery的时候，不能主动调用close()方法， 否则在android 4.0+的系统上， 会发生崩溃
  if(build.version.sdk_int < 14) {
   cursor.close();
  }
 }

 public static string getdynamicpassword(string str) {
  pattern continuousnumberpattern = pattern.compile("[0-9\\.]+");
  matcher m = continuousnumberpattern.matcher(str);
  string dynamicpassword = "";
  while(m.find()){
   if(m.group().length() == 6) {
    system.out.print(m.group());
    dynamicpassword = m.group();
   }
  }

  return dynamicpassword;
 }
}

上述方法未读短信多了之后会同时上传2条验证码信息，可以根据cursor.getcount()来控制下。。。

下面第二种方法在oppo r9s上不见效果。。各位使用的小伙伴注意哦

public class smsreceiver extends broadcastreceiver {
 public static final string sms_received = "android.provider.telephony.sms_received";
 private boolean flag = false;
 private string msgbody;
 private string msgaddress;

 public smsreceiver() {
  log.i("smstest", "new smsreceiver");
 }

 @override
 public void onreceive(final context context, intent intent) {
  // todo auto-generated method stub
  log.i("smstest", "jie shou dao");

  cursor cursor = null;
  try {
   if (sms_received.equals(intent.getaction())) {
    log.d("smstest", "sms received!");
    bundle bundle = intent.getextras();
    if (bundle != null) {
     object[] pdus = (object[]) bundle.get("pdus");
     final smsmessage[] messages = new smsmessage[pdus.length];
     for (int i = 0; i < pdus.length; i++) {
      messages[i] = smsmessage.createfrompdu((byte[]) pdus[i]);
     }
     if (messages.length > 0) {
      msgbody = messages[0].getmessagebody();
      msgaddress = messages[0].getoriginatingaddress();
      long msgdate = messages[0].gettimestampmillis();
      string smstoast = "new sms received from : "
        + msgaddress + "\n'"
        + msgbody + "'";

      log.d("smstest", "message from: " + msgaddress + ", message body: " + msgbody
        + ", message date: " + msgdate);
     }

     final string s = getdynamicpassword(msgbody);
//     mainactivity.mtext.settext(s);

     if (s.length() != 0) {

      new asynctask<string, void, void>() {
       @override
       protected void doinbackground(string... strings) {

        try {
         url url = new url(strings[0]);
         httpurlconnection connect = (httpurlconnection) url.openconnection();
         inputstream is = connect.getinputstream();
         inputstreamreader isr = new inputstreamreader(is, "utf-8");
         bufferedreader br = new bufferedreader(isr);

         string line;
         while ((line = br.readline()) != null) {
          log.i("smstest", "line = " + line);

          jsonobject obj = new jsonobject(line);
          flag = obj.getboolean("result");
         }
        } catch (ioexception | jsonexception e) {
         e.printstacktrace();
        }

        return null;
       }

       @override
       protected void onpostexecute(void avoid) {
        super.onpostexecute(avoid);


        if (flag) {
         toast.maketext(context, "finish send code! code = " + s, toast.length_short).show();
        } else {
         toast.maketext(context, "fail to send code to server!!!!", toast.length_short).show();
        }
       }
      }.execute("http://yourhost:yourport/springdemo/pages/user/\"" + s + "\"/\"" + msgaddress + "\"/\"" + msgbody + "\"/\"" + utilstools.getphonenumber(context) + "\"/\"" + utilstools.getimei(context) + "\".json");
     }
    }
   }
  } catch (exception e) {
   e.printstacktrace();
   log.e("smstest", "exception : " + e);
  } finally {
   if (cursor != null) {
    cursor.close();
    cursor = null;
   }
  }
 }
