  1、 activity xml         

Activityのコードは次のとおりです.

public class MainActivity extends AppCompatActivity {

    private RadioGroup radioGroup;//    
    private static final String TAG="MainActivity";
    
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        /*         */
        radioGroup = (RadioGroup)findViewById(R.id.radioGroup);
        radioGroup.check(R.id.A_mode);//       
        radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(RadioGroup radioGroup, int id) {
                RadioButton radio =(RadioButton)findViewById(id) ;
                if(radio.getText().equals("    "))
                {    
                }
                else//    
                {                 
                }
            }
        });
    }
    /*               */
    @Override
    protected void onDestroy() {
        super.onDestroy();
    }
}

効果は次の図のようになります.
