Answer 1

Use trim() method to remove the extra space

user_name.getText().toString().trim().

And Remove

if(str.length() > 0 && str.contains(" "))
                {
                    user_name.setError("Space is not allowed");
                    user_name.setText("");
                }

from your onTextChanged

To prevent user from entering space add this on your onTextChanged

if(str.equals(" "))
                {
                    user_name.setError("Leading Space is not allowed");
                    user_name.setText("");
                }
