Why do you want to use if else statement. You can do it in the easy way.

 int radioButtonId = rbGroup.getCheckedRadioButtonId();
 View radioButton = radioButtonGroup.findViewById(radioButtonId);

You can do like this to get the checked radiobutton from the radioGroup

RadioGroup g = (RadioGroup) findViewById(R.id.rBtnDigits);

switch (g.getCheckedRadioButtonId())
{
case R.id.rbtnButton1
//do something
break;

case R.id.rbtnButton2
//do something
break;
}

rg = (RadioGroup) findViewById(R.id.radioGroup1);
    button = (RadioButton) findViewById(R.id.radio0);

    rg.performClick();
    rg.setOnCheckedChangeListener(new OnCheckedChangeListener() { 

 public void onCheckedChanged(RadioGroup group, int checkedId) {
            // TODO Auto-generated method stub

            @SuppressWarnings("unused")
            int selected = rg.getCheckedRadioButtonId();

            pos = rg.indexOfChild(findViewById(rg.getCheckedRadioButtonId()));

            switch (pos) {
            case 0:
                Toast.makeText(getBaseContext(),
                        "You have Clicked RadioButton 1",
                        Toast.LENGTH_SHORT).show();
                break;
            case 1:
                Toast.makeText(getBaseContext(),
                        "You have Clicked RadioButton 2",
                        Toast.LENGTH_SHORT).show();
                break;
            case 2:
                Toast.makeText(getBaseContext(),
                        "You have Clicked RadioButton 3",
                        Toast.LENGTH_SHORT).show();
                break;
            default:
                Toast.makeText(getBaseContext(),
                        "You have Clicked RadioButton 4",
                        Toast.LENGTH_SHORT).show();
                break;

            }
        }

    });

it will give me error ..cannot resolve a symbol ischecked if(radioButton.isChecked()) { Toast.makeText(MainActivity.this, "FeMale option selected", Toast.LENGTH_LONG).show(); } — user3736680, Jun 26 '15 at 09:11
