Android如何通过手机自动获取短信验证码

本文实例为大家分享了Android实现手机自动获取短信验证码功能，供大家参考，具体内容如下

1、短信监听广播

2、读取短信内容

3、截取短信内容【可以 reg截取】

4、填写至相应控件

PS：DevStore测试没有获取到验证码

源码片段

public class MainActivity extends Activity {
 private BroadcastReceiver smsReceiver;
 private IntentFilter filter2;
 private Handler handler;
 private EditText et;
 private String strContent;
 private String patternCoder = "(?<!--\\d)\\d{6}(?!\\d)"; 

 @Override
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  et = (EditText) findViewById(R.id.et);
  handler = new Handler() {
   public void handleMessage(android.os.Message msg) {
    et.setText(strContent);
   };
  };
  filter2 = new IntentFilter();
  filter2.addAction("android.provider.Telephony.SMS_RECEIVED");
  filter2.setPriority(Integer.MAX_VALUE);
  smsReceiver = new BroadcastReceiver() {
   @Override
   public void onReceive(Context context, Intent intent) {
    Object[] objs = (Object[]) intent.getExtras().get("pdus");
    for (Object obj : objs) {
     byte[] pdu = (byte[]) obj;
     SmsMessage sms = SmsMessage.createFromPdu(pdu);
     // 短信的内容
     String message = sms.getMessageBody();
     Log.d("logo", "message  " + message);
     // 短息的手机号。。+86开头？
     String from = sms.getOriginatingAddress();
     Log.d("logo", "from  " + from);
     Time time = new Time();
     time.set(sms.getTimestampMillis());
     String time2 = time.format3339(true);
     Log.d("logo", from + " " + message + " " + time2);
     strContent = from + " " + message;
     handler.sendEmptyMessage(1);
     if (!TextUtils.isEmpty(from)) {
      String code = patternCode(message);
      if (!TextUtils.isEmpty(code)) {
       strContent = code;
       handler.sendEmptyMessage(1);
      }
     }
    }
   }
  };
  registerReceiver(smsReceiver, filter2);
 } 

 @Override
 protected void onDestroy() {
  super.onDestroy();
  unregisterReceiver(smsReceiver);
 } 

 /**
  * 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;
 }
