Question

在我的应用程序中，我试图从短信中读取otp而不在我的应用程序中输入内容。但它无法正常工作我无法找出错误我试图纠正错误超过一周，请帮我找出错误的位置，我创建一个类来读取传入的消息并将值传递给我的OTPActivity页面，但到达那里的空值

IncomingSms.java

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


                }

            } // bundle is null

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

        }
    }
}

OTPActivity

 @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
                Toast.makeText(getApplicationContext(), message, Toast.LENGTH_SHORT).show();


                mPinEditText.setText(message);
 }
        }
    };

    //Initialization Varibles
    private void initViews() {
        if ((ActivityCompat.checkSelfPermission(OTPActivity.this, Manifest.permission.READ_SMS) != PackageManager.PERMISSION_GRANTED)) {
            ActivityCompat.requestPermissions(OTPActivity.this, new String[]{Manifest.permission.READ_SMS}, 100);
        } else {
            //Permission Granted
        }
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        switch (requestCode) {
            case 100:
                if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                    //Permission Granted
                } else {
                    //Permission Not Granted
                    Toast.makeText(getApplicationContext(), "Permission not granted", Toast.LENGTH_SHORT).show();
                }
        }
    }

Answer 1

您需要在android:permission="android.permission.BROADCAST_SMS"中的接收器块中添加AndroidManifest.xml，这是接收短信所必需的。像这样：

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

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

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：

public class AuthActivity extends AppCompatActivity implements OnMessageListener {
    private SmsInterceptor smsInterceptor;
    private EditText etAuthPassword;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_auth);
        initViews();
        initSmsInterceptor();
    }

    @Override
    protected void onResume() {
        super.onResume();
        smsInterceptor.register();
    }

    @Override
    protected void onPause() {
        super.onPause();
        smsInterceptor.unregister();
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        smsInterceptor.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }

    @Override
    public void messageReceived(String message) {
        // You can perform your validation here
        etAuthPassword.setText(message);
    }

    private void initViews() {
        etAuthPassword = findViewById(R.id.etAuthPassword);
        etAuthPassword.addTextChangedListener(new SmsTextWatcher() {
            @Override
            public void onTextChanged(CharSequence charSequence, int i, int i1, int i2) {
                if (charSequence.length() == 4) {
                    btnAuthPassword.setEnabled(true);
                    checkCode();
                } else {
                    btnAuthPassword.setEnabled(false);
                }
            }
        });
    }

    private void initSmsInterceptor() {
        smsInterceptor = new SmsInterceptor(this, this);
        // Not necessary
        smsInterceptor.setRegex(SMS_CODE_REGEX);
        smsInterceptor.setPhoneNumber(PHONE_NUMBER);
    }

    private void checkCode() {
        // Validation
        if (isValid) {
            navigateToMainScreen();
        }
    }
}

从SMS读取otp并设置为编辑文本不起作用
