Question

我正在开发一个Android应用程序，其中服务器发送OTP并且用户需要在应用程序中输入此OTP，以登录我的应用程序，我想要的是，我的应用程序应该能够自动读取OTP由服务器发送。。我正在尝试实现自动检测OTP以在收到OTP时编辑文本，我试过但没有什么可以帮助我找出错误

Readsms.class

public class ReadSms extends BroadcastReceiver{

    @Override
    public void onReceive(Context context, Intent intent)
    {

        final Bundle bundle = intent.getExtras();
        try {

            if (bundle != null)
            {

                final Object[] pdusObj = (Object[]) bundle.get("pdus");
                for (int i = 0; i < pdusObj.length; i++)
                {

                    SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
                    String phoneNumber = currentMessage.getDisplayOriginatingAddress();
                    String senderNum = phoneNumber ;
                    String message = currentMessage .getDisplayMessageBody();

                    try
                    {

请使用此代码创建SMS阅读器广播接收器

public class IncomingSms extends BroadcastReceiver {

// Get the object of SmsManager
final SmsManager sms = SmsManager.getDefault();

public void onReceive(Context context, Intent intent) {

    // Retrieves a map of extended data from the intent.
    final Bundle bundle = intent.getExtras();

    try {

        if (bundle != null) {

            final Object[] pdusObj = (Object[]) bundle.get("pdus");

            for (int i = 0; i < pdusObj.length; i++) {

                SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) pdusObj[i]);
                String phoneNumber = currentMessage.getDisplayOriginatingAddress();

                String senderNum = phoneNumber;
                String message = currentMessage.getDisplayMessageBody().replaceAll("\\D", "");

                //message = message.substring(0, message.length()-1);
                Log.i("SmsReceiver", "senderNum: " + senderNum + "; message: " + message);

                Intent myIntent = new Intent("otp");
                myIntent.putExtra("message", message);
                myIntent.putExtra("number", senderNum);
                LocalBroadcastManager.getInstance(context).sendBroadcast(myIntent);
                // Show Alert

            } // end for loop
        } // bundle is null

    } catch (Exception e) {
        Log.e("SmsReceiver", "Exception smsReceiver" + e);

    }
}
}

在清单

中声明类

 <receiver android:name=".receiver.IncomingSms">
        <intent-filter>
            <action android:name="android.provider.Telephony.SMS_RECEIVED" />
        </intent-filter>
    </receiver>

清单中的权限

<uses-permission android:name="android.permission.RECEIVE_SMS" />
<uses-permission android:name="android.permission.READ_SMS" />
<uses-permission android:name="android.permission.SEND_SMS" />

您想要获取短信的活动。

@Override
public void onResume() {
    LocalBroadcastManager.getInstance(this).registerReceiver(receiver, new IntentFilter("otp"));
    super.onResume();
}
@Override
public void onPause() {
    super.onPause();
    LocalBroadcastManager.getInstance(this).unregisterReceiver(receiver);
}
private BroadcastReceiver receiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        if (intent.getAction().equalsIgnoreCase("otp")) {
            final String message = intent.getStringExtra("message");
            // message is the fetching OTP
        }
    }
};
