推荐答案
我建议您不要使用任何第三方库从SMS收件箱中自动提取OTP. 如果您对广播接收器及其工作原理有基本的了解，则可以轻松完成此操作. 只需尝试以下方法:
I will recommend you not to use any third party libraries for auto fetch OTP from SMS Inbox. This can be done easily if you have basic understanding of Broadcast Receiver and how it works. Just Try following approach :
步骤1)创建单个界面，即SmsListner
package com.wnrcorp.reba;
public interface SmsListener{
public void messageReceived(String messageText);}
第2步)创建单个广播接收器，即SmsReceiver
package com.wnrcorp.reba;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.telephony.SmsMessage;
public class SmsReceiver extends BroadcastReceiver {
private static SmsListener mListener;
Boolean b;
String abcd,xyz;
@Override
public void onReceive(Context context, Intent intent) {
Bundle data = intent.getExtras();
Object[] pdus = (Object[]) data.get("pdus");
for(int i=0;i<pdus.length;i++){
SmsMessage smsMessage = SmsMessage.createFromPdu((byte[]) pdus[i]);
String sender = smsMessage.getDisplayOriginatingAddress();
// b=sender.endsWith("WNRCRP"); //Just to fetch otp sent from WNRCRP
String messageBody = smsMessage.getMessageBody();
abcd=messageBody.replaceAll("[^0-9]",""); // here abcd contains otp
which is in number format
//Pass on the text to our listener.
if(b==true) {
mListener.messageReceived(abcd); // attach value to interface
object
}
else
{
}
}
}
public static void bindListener(SmsListener listener) {
mListener = listener;
}
}
第3步)在Android清单文件中添加监听器，即广播接收器
<receiver android:name=".SmsReceiver">
<intent-filter>
<action android:name="android.provider.Telephony.SMS_RECEIVED"/>
</intent-filter>
</receiver>
并添加权限
<uses-permission android:name="android.permission.RECEIVE_SMS"/>
最终步骤4)收件箱中收到otp时将自动提取otp的活动.就我而言，我正在获取otp并在edittext字段上进行设置.
public class OtpVerificationActivity extends AppCompatActivity {
EditText ed;
TextView tv;
String otp_generated,contactNo,id1;
GlobalData gd = new GlobalData();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_otp_verification);
ed=(EditText)findViewById(R.id.otp);
tv=(TextView) findViewById(R.id.verify_otp);
/*This is important because this will be called every time you receive
any sms */
SmsReceiver.bindListener(new SmsListener() {
@Override
public void messageReceived(String messageText) {
ed.setText(messageText);
}
});
tv.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
try
{
InputMethodManager imm=
(InputMethodManager)getSystemService(INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(),0);
}
catch(Exception e)
{}
if (ed.getText().toString().equals(otp_generated))
{
Toast.makeText(OtpVerificationActivity.this, "OTP Verified
Successfully !", Toast.LENGTH_SHORT).show();
}
});
}
}
