我正在使用Xamarin在其中的服務器發送OTP並且用戶需要在應用程序中輸入此OTP以對我的應用程序進行註冊的Android應用程序。我想要的是,我的應用程序應該能夠自動讀取服務器發送的OTP並在OTP的編輯文本字段中填寫。汽車OTP驗證android xamarin
我幾乎已經完成了讀取消息,但無法在編輯文本字段中設置otp。
短信廣播接收器類:
[BroadcastReceiver(Enabled = true, Label = "SMS Receiver")]
[IntentFilter(new string[] { "android.provider.Telephony.SMS_RECEIVED" })]
public class SMSBroadcastReceiver : BroadcastReceiver
{
private const string IntentAction = "android.provider.Telephony.SMS_RECEIVED";
public override void OnReceive(Context context, Intent intent)
{
try
{
if (intent.Action != IntentAction) return;
var bundle = intent.Extras;
if (bundle == null) return;
var pdus = bundle.Get("pdus");
// var castedPdus = JNIEnv.GetArray(pdus.Handle);
var castedPdus = JNIEnv.GetArray<Java.Lang.Object>(pdus.Handle);
var msgs = new SmsMessage[castedPdus.Length];
var sb = new StringBuilder();
string sender = null;
for (var i = 0; i < msgs.Length; i++)
{
var bytes = new byte[JNIEnv.GetArrayLength(castedPdus[i].Handle)];
JNIEnv.CopyArray(castedPdus[i].Handle, bytes);
string format = bundle.GetString("format");
msgs[i] = SmsMessage.CreateFromPdu(bytes,format);
if (sender == null)
sender = msgs[i].OriginatingAddress;
sb.Append(string.Format("SMS From: {0}{1}Body: {2}{1}", msgs[i].OriginatingAddress,System.Environment.NewLine, msgs[i].MessageBody));
Toast.MakeText(context, sb.ToString(), ToastLength.Long).Show();
}
}
catch (System.Exception ex)
{
Toast.MakeText(context, ex.Message, ToastLength.Long).Show();
}
}
}
這裏是我的主要活動:
[Activity(Label = "UserSms", MainLauncher = true, Icon = "@drawable/icon")]
public class MainActivity : Activity
{
protected override void OnCreate(Bundle bundle)
{
base.OnCreate(bundle);
// Set our view from the "main" layout resource
SetContentView (Resource.Layout.Main);
SMSBroadcastReceiver smsReceiver = new SMSBroadcastReceiver();
TextView msg = FindViewById<TextView>(Resource.Id.editTextOtp);
Button btn = FindViewById<Button>(Resource.Id.button3);
RegisterReceiver(smsReceiver, new IntentFilter("android.provider.Telephony.SMS_RECEIVED"));
}
}
我怎樣才能做到這一點?任何有關這方面的幫助或指導將受到高度讚賞。
更新
public void onSMSReceived(string msgs)
{
EditText OtpNumber = (EditText)FindViewById(Resource.Id.editTextOtp);
try
{
OtpNumber.SetText(msgs.ToString(),null);
}
catch (System.Exception ex)
{
}
}
我試過,但對於me.Can你細說這一點bit.Thanks –
這部分你不明白它不工作? – Geek
按照你的建議實施,但它沒有奏效。你可以提供示例代碼。它可以節省我的一天 –
