确认密码字段不起作用

Question

我正在尝试匹配两个密码字段但其显示密码不匹配

 else if (_passwordText.getText().toString().equals("") || _passwordText.length() < 4 || _passwordText.length() > 10) {
        AlertDialog alertDialog = new AlertDialog.Builder(Register.this).create();
        alertDialog.setTitle("oops!");
        alertDialog.setMessage("Password  field is empty");
        alertDialog.show();
    }


   else if (_repasswordText.getText().toString().equals(_passwordText.getText().toString())) {
        AlertDialog alertDialog = new AlertDialog.Builder(Register.this).create();
        alertDialog.setTitle("oops!");
        alertDialog.setMessage("Passwords do not match");
        alertDialog.show();
        }

Answer 1

else if (_passwordText.getText().toString().equals("")  {
        AlertDialog alertDialog = new AlertDialog.Builder(Register.this).create();
        alertDialog.setTitle("oops!");
        alertDialog.setMessage("Password  field is empty");
        alertDialog.show();
    }


   else if (!_repasswordText.getText().toString().equals(_passwordText.getText().toString())) {
        AlertDialog alertDialog = new AlertDialog.Builder(Register.this).create();
        alertDialog.setTitle("oops!");
        alertDialog.setMessage("Passwords do not match");
        alertDialog.show();
        }

<强> FYI

1. 首先检查 equals("")
2. 在 _repasswordText.getText（）。toString（）
之前添加!符号

Answer 2

您应该在

之前添加!

_repasswordText.getText().toString().equals(_passwordText.getText().toString())

Answer 3

您可以使用_repasswordText.getText().toString().contentEquals(_passwordText.getText().toString())
