Answer 1

When you press one button first, you toggle that button only

When you press the other button, you toggle both buttons. Therefore your onCheckedChanged is checked once the first time you press one of the radiobuttons, and two times the next time.

Taken from http://developer.android.com/guide/topics/ui/controls/radiobutton.html

public void onRadioButtonClicked(View view) {
   // Is the button now checked?
   boolean checked = ((RadioButton) view).isChecked();

   // Check which radio button was clicked
   switch(view.getId()) {
      case R.id.radio_pirates:
         if (checked)
            // Do all things here for this button
         break;
      case R.id.radio_ninjas:
         if (checked)
            // Do all things here for this button
         break;
}

Just do the things you want to if the button is checked.
