Answer 1

Ваш вопрос на самом деле вызывает большую проблему, которая особенно актуальна при разработке мобильных приложений: Locale. Вместо использования Double.parse(), который не учитывает Locale, вместо этого используйте вместо этого NumberFormat.

NumberFormat nf = NumberFormat.getInstance(); //gets an instance with the default Locale 
Number parsed = nf.parse(percentageView.getText().toString()); 
beanEachQuetionScore.quetionScore = parsed.doubleValue(); 

Для ваших значений с плавающей точкой, вы можете использовать ту же концепцию:

Number parsedFloat = nf.parse(someFloatString); 
float floatVal = parsedFloat.floatValue(); 

Это, конечно, предполагает, что ФП в Locale, который использует «» вместо «» как разделитель.
