In your XML file, you can set the following attribute on the radio button you want selected: android:checked="true"

Or programmatically, you can select the radio button by using the following method written in your onCreate:

RadioButton radioButton = (RadioButton) findViewById(R.id.radio1);
radioButton.setChecked(true);
