Defining radio group?

Question

I am trying to set an OnCheckedChangeListeneron a RadioGroup but Android Studio gives me an error when I write it. I used for the radio group

RadioGroup CheckList1 = (RadioGroup)findViewById(R.id.First_id_radio_group);
RadioGroup.setOnCheckedChangeListener(new OnCheckedChangeListener) {

}

When I write it as suggested (CheckList1.setOnCheckedChangeListener(...)), I get the following warning in Android Studio, the method gets crossed out:

It needs to be `CheckList1.setOnCheckedChangeListener(new OnCheckedChangeListener(){/* Your implementation goes here */});`, but variable names in Java should be camelCase, so make it `checkList1`. — Markus Kauppinen, Aug 15 '18 at 09:54
I did what you told me now but there is a line on setOnCheckedChangeListener is it normal ?? — Adnan Abou-Elenein, Aug 15 '18 at 09:58
Edit your question, click on the *image*-icon and paste a link or upload your local image by drag'n'drop... — deHaar, Aug 15 '18 at 10:02
That *line* means the method is deprecated and you should use another option, but it should work (with certain limits that made the method become deprecated). — deHaar, Aug 15 '18 at 10:07

RadioGroup radioGroup = (RadioGroup) findViewById(R.id.yourRadioGroup);        
radioGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() {
    @Override
    public void onCheckedChanged(RadioGroup group, int checkedId) {
        // checkedId is the RadioButton selected
    } 
});
