Android Firebase使用电子邮件和密码登录 [英] Android Firebase sign in with email and password

问题描述

我有一个android应用程序和一个Firebase数据库.我设置的登录名包含电子邮件和密码.效果很好，但是当我尝试使用空白电子邮件和密码登录时，应用程序崩溃了.

I have an android app and a Firebase database. The login I've set is with email and password. It works great, but when I try and login with blank email and password the app crashes.

这是我的代码

final String Email = email.getText().toString();
final String Password = password.getText().toString();
mAuth.signInWithEmailAndPassword(email, password).addOnCompleteListener(ThisActivity.this, new OnCompleteListener<AuthResult>() {
          @Override
          public void onComplete(@NonNull Task<AuthResult> task) {
                      if (!task.isSuccessful()) {
                                Toast.makeText(ThisActivity.this, "sign in error", Toast.LENGTH_SHORT).show();
                      } else
                                mAuth.addAuthStateListener(firebaseAuthListener);
          }
});
break;

推荐答案

这将帮助您:)

final String Email = email.getText().toString();
final String Password = password.getText().toString();

if(!TextUtils.isEmpty(Email) && !TextUtils.isEmpty(Password)) {
        mAuth.signInWithEmailAndPassword(email, password).addOnCompleteListener(CustomerLoginActivty.this, new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
                    if (!task.isSuccessful()) {

                        Toast.makeText(ThisActivity.this, "sign in error", Toast.LENGTH_SHORT).show();
                    } else
                        mAuth.addAuthStateListener(firebaseAuthListener);
                }
            });
            break;
        }
