Question

我需要触发toast说具有相同电子邮件的用户已经注册。在注册时出现问题时，在我的代码Toast触发器中。例如密码太短。但是，当用户尝试使用已经采用的电子邮件进行注册时，他并不知道这一点。请帮帮我，告诉我该如何编辑我的代码？

private void registerUser(){
    String email = editTextemail.getText().toString().trim();
    String password = editTextpassword.getText().toString().trim();

    if(TextUtils.isEmpty(email)){
        Toast.makeText(this, "Enter email ", Toast.LENGTH_SHORT).show();
    return;
    }

    if(TextUtils.isEmpty(password)){
        Toast.makeText(this, "enter password", Toast.LENGTH_SHORT).show();
    return;
    }
    progressDialog.setMessage("please wait...");
    progressDialog.show();
    firebaseAuth.createUserWithEmailAndPassword(email,password).addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
        @Override
        public void onComplete(@NonNull Task<AuthResult> task) {
            if(task.isSuccessful()){
                progressDialog.dismiss();
                Toast.makeText(MainActivity.this, "registration complete", Toast.LENGTH_SHORT).show();

            }else{
                progressDialog.dismiss();
                Toast.makeText(MainActivity.this, "Email is invalid or password contains less than 6 symbols", Toast.LENGTH_SHORT).show();

            }
        }
    });
}

在其他人之后编辑您的代码：

progressDialog.dismiss();    

String message = "The email address is already in use by another account."       

if (task.getException().getMessage().equals(message))  
       Toast.makeText(MainActivity.this, message, Toast.LENGTH_SHORT).show();    
else     
    Toast.makeText(MainActivity.this, "Email is invalid or password contains less than 6 symbols", Toast.LENGTH_SHORT).show();

Firebase android auth email已经存在特殊触发器
