RadioButton invalid double

Question

I want to have 5 RadioButtons, and all of them aredescribed with text in XML file. And I want them to hold double value, different for each button. And user has to input one number and then select one of the five options avalible in RadioButtons, then press on regular Button and that button will do the calculation (multiply entered number with double number holded by RadioButton).

I get force close error:

java.lang.NumberFormatException: Invalid double: "Sjedeći (Malo ili bez aktivnosti, pretežno sjedeći posao)"

This is my java file:

SOLVED!

btnIzracunajTDEE.setOnClickListener(new View.OnClickListener(){
            @Override
            public void onClick(View v){

                double input = Double.parseDouble(unesiteBMR.getText().toString());
               double prviButton = 1.2;
                double drugiButton = 1.375;
                double treciButton = 1.55;
                double cetvrtiButton = 1.725;
                double petiButton = 1.9;

                double rezultat = 0;


                if (radioBtn1.isChecked()){
                    rezultat = input * prviButton;
                } else if(radioBtn2.isChecked()){
                    rezultat = input * drugiButton;
                } else if (radioBtn3.isChecked()){
                    rezultat = input * treciButton;
                } else if (radioBtn4.isChecked()) {
                    rezultat = input * cetvrtiButton;
                } else if (radioBtn5.isChecked()) {
                    rezultat = input * petiButton;
                }
                textRezultatTDEE.setText(Double.toString(rezultat));
            }
        });

    }
}

Remove the following, which attempts to convert your radiobuttons texts into double, and causes the crash :

double prviButton = Double.parseDouble(radioBtn1.getText().toString());
double drugiButton = Double.parseDouble(radioBtn2.getText().toString());
double treciButton = Double.parseDouble(radioBtn3.getText().toString());
double cetvrtiButton = Double.parseDouble(radioBtn4.getText().toString());
double petiButton = Double.parseDouble(radioBtn5.getText().toString());

Instead, just initialize your double fields with the values they should have, like this :

double prviButton = 1.2;
double drugiButton = 1.375;
double treciButton = 1.55;
double cetvrtiButton = 1.725;
double petiButton = 1.9;
