Question

朋友，我正在研究Kotlin，并尝试在编辑文本中获取收到的SMS。我不知道如何实现它。如果有人有正确的Kotlin代码来获取OTP，请在下面发布它，但是我已经按照下面的方法进行了实现并堆积在实现中，因此如果有人拥有，请在下面的Kotlin代码中发布

class SmsReceiver: BroadcastReceiver() {

    private val mListener: SmsListener? = null
    var b: Boolean? = null
    var abcd: String? = null
    var xyz:String? = null

    @Suppress("DEPRECATION")
    override fun onReceive(context: Context?, intent: Intent?) {
        //val bundle = intent!!.getExtras()
        val data = intent!!.extras
        val pdus = data.get("pdus") as Array<Any>


    }
}

以下是活动

public class OtpActivity extends Activity
{
    EditText ed;
    TextView tv;
    String otp_generated,contactNo,id1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.otp);
        ed=(EditText)findViewById(R.id.otp_et);
        tv=(TextView) findViewById(R.id.verify_otp);

        SmsReceiver.bin(new SmsListener() {
            @Override
            public void messageReceived(String messageText) {
                ed.setText(messageText);
            }
        });

    }
}

这可以通过RxJava完成：

public static Observable<String> createMessageMonitor(@NonNull final Context context) {
        IntentFilter intentFilter = new IntentFilter();
        intentFilter.addAction("android.provider.Telephony.SMS_RECEIVED");
        return fromIntentFilter(context, intentFilter)
                .filter(intent -> intent != null && intent.getExtras() != null)
                .map(intent -> {
                    Bundle bundle = intent.getExtras();
                    Object[] pdu_Objects = (Object[]) bundle.get("pdus");
                    if (pdu_Objects != null) {
                        for (Object aObject : pdu_Objects) {
                            final SmsMessage currentSMS = getIncomingMessage(aObject, bundle);
                            final String senderNumber = currentSMS.getDisplayOriginatingAddress();
                            final String message = currentSMS.getDisplayMessageBody().trim();
                            Matcher matcher = OTP_PATTERN.matcher(message);
                            if (matcher.matches()) {
                                return matcher.group(1);
                            }
                        }
                    }
                    return "";
                }).filter(message -> !message.isEmpty());

    }

您的OTP_PATTERN：

private static Pattern OTP_PATTERN = Pattern.compile("^(\\d{4}) is the OTP for your App.$");

然后订阅该流：

RxBroadcastReceivers2.createMessageMonitor(this)
                .subscribeWith(this,
                        onNext = { /*Your OTP is here*/ },
                        onError = {
                            Timber.e(it, "Registration permission request failed")
                        }
                )

注意：在使用Manifest.permission.READ_SMS方法之前，您需要先获得createMessageMonitor。

如果您不想编写接收器，则可以使用简单的轻量级库https://github.com/VitaliBov/SmsInterceptor

该库与Kotlin具有100％的兼容性

您只需要重写接口方法，创建一个Interceptor类并将其与生命周期绑定。看起来像这样：

SELECT
    D.Enroll_Month
,   cncl_mnth
,   mth
,   tot_orders
,   tot_cancel
,   tot_orders - total_cancel active_count
,   100 - CAST(CAST((tot_orders - total_cancel) AS DECIMAL(18,2) ) / (tot_orders) * 100  AS DECIMAL(18,2) )  attr_rate
,   CAST(CAST((tot_orders - total_cancel) AS DECIMAL(18,2) ) / (tot_orders) * 100  AS DECIMAL(18,2) ) retn_rate
FROM (
    SELECT
        d.Enroll_Month
    ,   d.cncl_mnth
    ,   d.mth
    ,   s.tot_orders
    ,   d.tot_cancel
    ,   SUM(d.tot_cancel) OVER(PARTITION BY d.Enroll_Month ORDER BY mth ROWS UNBOUNDED PRECEDING) total_cancel
    FROM @summary s
    JOIN @Detail d ON s.Enroll_Month = d.Enroll_Month
) D
