Incompatible types: android.widget.Edit Text and j

Question

I have got this error on Android Studio IDE. It says

Incompatible types; Required android.widget.EditText and Found java.lang.String

@Override
public void afterTextChanged(Editable s) {

    if (editabletext.length() == 8) {
        editabletext = editabletext.getText().toString().replaceAll("([0-9]{4})([0-9]{4})", "$1-$2")
    }
}

Answer 1

editabletext is an EditText and replaceAll returns a String. What the compiler says is that you can't assign a String to an EditText. You could change your code this way:

if(editabletext.length() == 8){
    String tmp = editabletext.getText().toString().replaceAll("([0-9]{4})([0-9]{4})", "$1-$2");
    editabletext.setText(tmp);
  }

Answer 2

Replace

editabletext= editabletext.getText().toString().replaceAll("([0-9]{4})([0-9]{4})", "$1-$2")

with

editabletext.setText(editabletext.getText().toString().replaceAll("([0-9]{4})([0-9]{4})", "$1-$2"))

as editabletext is of type Editable and replaceAll returns a String

Answer 3

find the definition of "editabletext" and change the type from EditText to String
