java - String array value not matching edittext

I have a string array with values which I am trying to compare against text inputted into an edittext field. However despite both the edittext and the value in the array being the same my if (answer == guess) never resolves to true.

I've put debugging via Toast messages and it shows both answer and guess are the same. Can someone help with this please? Code below:

    final EditText et;

    et = (EditText) findViewById(R.id.editText1);
    String guess = et.getText().toString();

    String answer = LinesFromFile[LineNumber]; 

    if (answer == guess)
    {
        Toast msg = Toast.makeText(getBaseContext(), answer + " " + guess + " right", Toast.LENGTH_LONG);
        msg.show();
    }

    else
    {

        Toast msg = Toast.makeText(getBaseContext(), answer + " " + guess + " wrong", Toast.LENGTH_LONG);
        msg.show();         
    }

Answer

You can't do string comparisons using == ... you need to use String.equals()

if (answer.equals(guess))
{
  ...
