Get index of String in String Array

Question

I want to check if a String (coming from an EditText) is part of a String Array and I need the index. I have got a TextWatcher added as TextChangedListener like the following:

inside Activity-Class:

private String[] randomSpanishWords = { "pueblo", "madre" };

private TextWatcher ETListener = new TextWatcher() {
    @Override
    public void beforeTextChanged(CharSequence charSequence, int i, int i2, int i3) {

    }

    @Override
    public void onTextChanged(CharSequence charSequence, int i, int i2, int i3) {

        int index = Arrays.asList(randomSpanishWords).indexOf(charSequence);
    }

    @Override
    public void afterTextChanged(Editable editable) {

    }
};

in onCreate():

editText1.addTextChangedListener(ETListener);

No matter what Im typing in the EditText, index is always -1. What am I missing?

Have you debugged the value of charSequence? Unless it is equal to pueblo or madre, the result will always be -1. — JamesB

Try to convert your charSequence to String with

charSequence.toString()

Or use CharSequence for your array

private CharSequence[] randomSpanishWords = { "pueblo", "madre" };

Great ! As I suspected, List.indexOf must check the class before comparing values with equals(). But I suspect this is android-specific
