java - Firebase signInWithEmailAndPassword 总是跳到其他

Question

我正在尝试在 Android 上使用 Firebase 创建一个登录和注册页面，我可以注册用户但不能登录，我可以在数据库中看到注册用户。登录方法总是转到 else 部分。这是代码

    mLogin_btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            String email = mLoginEmail.getEditText().toString();
            String password = mLoginPassword.getEditText().toString();
            if(!TextUtils.isEmpty(email) && !TextUtils.isEmpty(password)){
                mLoginProgress.setTitle("Loggin In");
                mLoginProgress.setMessage("Please Wait!");
                mLoginProgress.setCanceledOnTouchOutside(false);
                mLoginProgress.show();

                loginUser(email, password);
            }
        }
    });

}


private void loginUser(String email, String password) {
    mAuth.signInWithEmailAndPassword(email, password).addOnCompleteListener(new OnCompleteListener<AuthResult>() {
        @Override
        public void onComplete(@NonNull Task<AuthResult> task) {

            if(task.isSuccessful()){

                mLoginProgress.dismiss();

                        Intent mainIntent = new Intent(LoginActivity.this, MainActivity.class);
                        mainIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK);
                        startActivity(mainIntent);
                        finish();

                    } else{
                mLoginProgress.hide();
                Toast.makeText(LoginActivity.this, "nope, skipping to else", Toast.LENGTH_SHORT).show();
            }
                }
});
}
}

Answer 1

试试这个:

 else{
     mLoginProgress.hide();
    Toasty.error(getApplicationContext(), "Authentication failed: " + task.getException().getMessage(), Toast.LENGTH_SHORT).show();
        }

把你的toast换成上面的toast就能知道为什么要转到else语句了。

改变这个:

  String email = mLoginEmail.getEditText().toString();
  String password = mLoginPassword.getEditText().toString();

为此:

  String email = mLoginEmail.getText().toString();
  String password = mLoginPassword.getText().toString();
