Answer 1

you can use setOnCheckedChangeListener try this :

itemtypeGroup
        .setOnCheckedChangeListener(new OnCheckedChangeListener() {

            @Override
            public void onCheckedChanged(RadioGroup group, int checkedId) {
Log.d("chk", "id" + checkedId);

                if (checkedId == R.id.radio_button_equal_payment_principal) {
                    // "display method PaymentPrincipal" 
                } else if (checkedId == R.id.radio_button_equal_payment_total) {
                    //  "display method PaymentTotal"
                }

            }

        });

Answer 2

you can try following code:

radioGroup = (RadioGroup) findViewById(R.id.radioSex);
     radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
         @Override
         public void onCheckedChanged(RadioGroup group, @IdRes int checkedId) {
             switch(checkedId){
                 case R.id.radio1:
                     // do operations specific to this selection
                     break;
                 case R.id.radio2:
                     // do operations specific to this selection
                     break;

             }
         }
     });
