想了解Android实现获取短信验证码并自动填写功能的相关内容吗,七禾叶在本文为您仔细讲解Android获取短信验证码并自动填写的相关知识和一些Code实例,欢迎阅读和指正,我们先划重点:Android获取短信验证码,Android短信验证码自动填写,Android自动获取验证码,下面大家一起来学习吧。

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;
   }
  }
 }
