As such, it does run, but the if and else if statements do not run and I can not find a solution to debug

The correct way to define the RadioButton that is being activated within the RadioGroup , is by its id, this id can be obtained by means of the second parameter of the method onCheckedChanged() :

public void onCheckedChanged(RadioGroup radioGroup, int idCheck)

Therefore to know what is the RadioButton selected according to your code, it will be done in this way:

radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
        @Override
        public void onCheckedChanged(RadioGroup group, int checkedId) {

            if (checkedId == R.id.RB1) {
             ...
             ...
             ...
            } else  if (checkedId == R.id.RB2) {
             ...
             ...
             ...
            } else  if (checkedId == R.id.RB3) {
             ...
             ...
             ... 
            }

        }
    });

Ensure that the used import is:

import android.widget.RadioGroup;

and that the RadioButtons are actually within the RadioGroup :

<RadioGroup
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_below="@+id/text"
    android:id="@+id/RG">

    <RadioButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/RB1"/>

    <RadioButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/RB2"/>

    <RadioButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/RB3"/>

</RadioGroup>

I add a example to check the behavior.
