Your line of code
if(R.id.radioButton == checked) incomprehensible. You compare type int with a certain variable checked . Since your variable is not initialized, the compiler gives an error. In general, if you want to check if a RadioButton is RadioButton , then you need to do it this way.
RadioButton rb = (RadioButton)findViewById(R.id.radioButton); if(rb.isChecked()) //если выбрана
