public View onCreateView (LayoutInflater inflater, ViewGroup container , Bundle savedInstanceState){
    ViewGroup rootView = (ViewGroup) inflater.inflate(R.layout.currency , container , false);
    return rootView;

//i have "unreachable statement" error in only this "editmeter" line

    final EditText editmeter = (EditText) getView().findViewById(R.id.editMeter);
    final EditText editinch = (EditText) getView().findViewById(R.id.editInch);
    final EditText editcentimeter = (EditText) getView().findViewById(R.id.editCentimeter);
    final EditText edityard = (EditText) getView().findViewById(R.id.editYard);
    final EditText editfeet = (EditText) getView().findViewById(R.id.editFeet);
    TextView textmeter = (TextView) getView().findViewById(R.id.textMeter);
    TextView textinch = (TextView) getView().findViewById(R.id.textInch);

    TextView textyard = (TextView) getView().findViewById(R.id.textYard);
    TextView textfeet = (TextView) getView().findViewById(R.id.textFeet);
    TextView button = (TextView) getView().findViewById(R.id.buttonConvert);



    Typeface font = Typeface.createFromAsset(getActivity().getAssets(), "CoffeeHouse.ttf");
    textmeter.setTypeface(font);
    textinch.setTypeface(font);
    textcentimeter.setTypeface(font);

Answer 1

The return keyword signifies the last line of the method. It forces your method to return the value of rootView, all lines below that will never be reached. This is why the return statement should be the last statement of the method, unless it is within a conditional block.
