无法识别switch语句

Question

I try to read the cases of a simple radiogroup. So instead of showing the selected value via toast (like in a working example), I want so sum the "score" depending on the selected radiobutton.

So the code lines in this area (MainActivity.java) that I tried:

public void onClick(View v) {
  int selected_id = radio_group_question1.getCheckedRadioButtonId();
  radio_button_question1 = (RadioButton)findViewById(selected_id);
  switch(radio_group_question1.getId()) {
    case R.id.radio_q1_answer1:
    score = score + 0;
    break;
    case R.id.radio_q1_answer2:
    score = score + 1;
    break;
    ...
  }
  ...
}

Unfortunately the "score" is always "0" like I initialized in the beginning (int score = 0;). :(

Any ideas?

Many thanks and greetings!

在switch语句中，您要检查radio_group_question1.getId()它是整个无线电组的ID radio_group_question1.getId() ，您应该执行以下操作：

switch(selected_id){
