我不知道代码有什么问题。我只是想向用户的电子邮件发送重置密码电子邮件。如果您愿意，可以查看完整代码here。非常感谢任何帮助，提前感谢！：d

代码：

    public void PassResetViaEmail(View view)
{
    AlertDialog.Builder alertdialog = new AlertDialog.Builder(Settings.this);
    alertdialog.setTitle("Reset password");
    alertdialog.setMessage("Enter email below");

    input = new EditText(this);
    email = input.getText().toString().trim();
    alertdialog.setView(input);


    alertdialog.setPositiveButton("Send", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            ResetEmailSender();
        }
    });
    alertdialog.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int which) {
            dialog.dismiss();
        }
    });
    alertdialog.show();
}

public void ResetEmailSender()
{
    auth = FirebaseAuth.getInstance();
    auth.sendPasswordResetEmail(email)
            .addOnCompleteListener(new OnCompleteListener<Void>() {
                @Override
                public void onComplete(@NonNull Task<Void> task) {
                    if (task.isSuccessful()) {
                        Toast.makeText(Settings.this, "We have sent you instructions to reset your password!", Toast.LENGTH_SHORT).show();
                    } else {
                        Toast.makeText(Settings.this, "Failed to send reset email!", Toast.LENGTH_SHORT).show();
                    }
                }
            });
}

错误：

因为我输入了一封电子邮件，所以这是不可能的

也许你做过，但是因为你得到了这个非常奇怪的代码，这没什么区别：

input = new EditText(this);
email = input.getText().toString().trim();

创建EditText并立即从中读取是没有意义的。因为它还没有显示，所以每次都不会给你任何空字符串。一旦取消对话框，你应该考虑阅读它。
