Answer 1

I believe this solved my problem.

submit.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                String phoneNum = editText.getText().toString();
                Toast.makeText(MainActivity.this, phoneNum, Toast.LENGTH_SHORT).show();
                verifyPhone(phoneNum,mCallBacks);
            }

    });

I tried to make a method to handle the button clicked, I dont know why but it worked..

 public void verifyPhone(String phoneNumber, PhoneAuthProvider.OnVerificationStateChangedCallbacks mCallbacks){
            PhoneAuthProvider.getInstance().verifyPhoneNumber(
                    phoneNumber,        // Phone number to verify
                    60,                 // Timeout duration
                    TimeUnit.SECONDS,   // Unit of timeout
                    this,               // Activity (for callback binding)
                    mCallbacks);        // OnVerificationStateChangedCallbac
        }

Answer 2

You should use a PhoneAuthProvider.OnVerificationStateChangedCallbacks() . Like so:

    PhoneAuthProvider.getInstance().verifyPhoneNumber(
            phoneNumber,        // Phone number to verify
            60,                 // Timeout duration
            TimeUnit.SECONDS,   // Unit of timeout
            this,               // Activity (for callback binding)
            new PhoneAuthProvider.OnVerificationStateChangedCallbacks() {
                @Override
                public void onVerificationCompleted(PhoneAuthCredential phoneAuthCredential) {

                }

                @Override
                public void onVerificationFailed(FirebaseException e) {

                }
            });

Then you could just override the other Verification callbacks that you need.

Answer 3

不要在 verifyPhoneNumber(..) 方法中传递“this”，而是尝试传递 Activityname.this

Answer 4

方法 verifyPhoneNumber 中 TimeUnit.SECONDS 的问题您必须替换 import Class TimeUnit 以import java.util.concurrent.TimeUnit ；
