If EditText.getText().ToString() == “” dont work; [duplicate]

Answer 1

Do not use == with Strings use equals()

if(editText.getText().toString().equals("")){
   editTextBenefaction.setText("0");
}

Answer 2

Change it to

if(editText.getText().toString().equals("")){

In Java .equals() is used to compare if they have the same value and "==" is used to determine if they reference the same object.

An even better way is to use

if("".equals(editText.getText().toString())){

because this will protect against a NPE.
