我有一个Otp验证屏幕，其中我有一个带有计时器的进度条，我想要的是一旦从收件箱中读取Otp，如果从收件箱中成功读取，则关闭此进度条然后关闭进度条并执行Jsons Url如果没有则显示进度条计时器直到没有从Inbox读取短信。为此我使用广播接收器。请帮助我。
这是我的MainActivity代码： -
public class COtpAutoVerificationScreen extends Fragment {
private static String s_szResult = "";

private String m_szMobileNumber;
private String m_szEncryptedPassword;
private CircularProgressView m_ProgressView;
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
m_Main = inflater.inflate(R.layout.otp_auto_verified, container, false);
getUserDetails();// getuser deatails....
init();// initialize controls...
return m_Main;
}
private void getUserDetails() {
m_oSessionManagement = new CRegistrationSessionManagement(getActivity());

final TextView tv = (TextView) m_Main.findViewById(R.id.tv);
@SuppressWarnings("UnusedAssignment") final TextView validationText = (TextView) m_Main.findViewById(R.id.validatingmessage);
tv.setText("00:00");
//Initialize a new CountDownTimer instance

new CountDownTimer(m_MillisInFuture, m_CountDownInterval) {

@SuppressWarnings("UnusedAssignment") long millis = millisUntilFinished;
String hms = String.format("%02d:%02d", TimeUnit.MILLISECONDS.toMinutes(millisUntilFinished),
TimeUnit.MILLISECONDS.toSeconds(millisUntilFinished) -

System.out.println(hms);
tv.setText(hms);
//Another one second passed
//Each second ProgressBar progress counter added one
m_n_ProgressStatus += 1;
pb.setProgress(m_n_ProgressStatus);
}
public void onFinish() {
// retreive user data from shared preferencce........

m_szEncryptedPassword = user.get(CRegistrationSessionManagement.s_szKEY_PASSWORD).trim();

// exc=ecuting request for otp verfiifcation to server

//Display the CountDownTimer initial value

}
// sending OTP to server to verify Otp

这是我的BroadcastReceiver类： -
public class CSmsBroadcastReceiver extends BroadcastReceiver {
private static final String s_szTAG = CSmsBroadcastReceiver.class.getSimpleName();
private static String m_szOtpCode;
@Override
public void onReceive(Context context, Intent intent) {
final Bundle bundle = intent.getExtras();
try {
if (bundle != null) {
Object[] pdusObj = (Object[]) bundle.get("pdus");
assert pdusObj != null;
for (Object aPdusObj : pdusObj) {
@SuppressWarnings("deprecation") SmsMessage currentMessage = SmsMessage.createFromPdu((byte[]) aPdusObj);
String phoneNumber = currentMessage.getDisplayOriginatingAddress();
String message = currentMessage.getDisplayMessageBody();
Log.e(s_szTAG, "Received SMS: " + message + ", Sender: " + phoneNumber);
// checking sms sender address....
if (phoneNumber.toLowerCase().contains("+919971599707".toLowerCase())) {
// verification code from sms
m_szOtpCode = getVerificationCode(message);
assert m_szOtpCode != null;
String input = m_szOtpCode.trim();
Log.e(s_szTAG, "OTP received: " + m_szOtpCode);
COTPVerificationDataStorage.getInstance().setM_szOtp(input);// getting otp from SMS and set to otpverificationstorage class
} else {
return;
}
}
}
} catch (Exception e) {
Log.e(s_szTAG, "Exception: " + e.getMessage());
}
}
/**
* Getting the OTP from sms message body
* ':' is the separator of OTP from the message
*
* @param message
* @return
*/
@SuppressWarnings("JavaDoc")
private String getVerificationCode(String message) {
String code;
int index = message.indexOf(":");
if (index != -1) {
int start = index + 2;
int length = 6;
code = message.substring(start, start + length);
return code;
}
COTPVerificationDataStorage.getInstance().setM_szOtp(m_szOtpCode);
return null;
}
}
答案 0 :(得分：0)
基本上，您希望在需要的消息到来时将数据从广播接收器发送到活动。您可以使用interface进行通信
在你BroadcastReceiver创建这样的界面
public interface OnSmsReceivedListener {
public void onSmsReceived(String message);
}
添加一个方法来初始化接口引用
OnSmsReceivedListener smsListener;
public void setOnSmsReceivedListener(Context context) {
this.smsListener = (OnSmsReceivedListener) context;
}
使用此引用来调用onReceive()方法
smsListener.onSmsReceived("Message Received!!!");
您已完成发布数据，现在在您的Activity中实现界面并关闭您的对话框。
public class SampleActivity extends Activity implements OnSmsReceivedListener
@Override
public void onSmsReceived(String message) {
//Dismiss your dialog here
}
