Question

I have RadioGroup in xml. And I am filling it with RadioButton from code.
Problem is, in Emulators RadioButtons do not behave w.r.t RadioGroup. I can select all radiobuttons at once. But everything seems to work fine on real device.

Below are screenshots and code for all files:

Source for MainActivity.java

public class MainActivity extends Activity {
/** Called when the activity is first created. */
private RadioGroup rg;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    LayoutInflater inflater = LayoutInflater.from(getBaseContext());
    rg = (RadioGroup)findViewById(R.id.rg);

    for (int i = 0; i < 5; i++) {
        inflater.inflate(R.layout.myradio, rg,true);
    }

}

}

<?xml version="1.0" encoding="utf-8"?>

</RadioGroup>

<?xml version="1.0" encoding="utf-8"?>

<RadioButton xmlns:android="http://schemas.android.com/apk/res/android"

Answer 1

It will be like this

public class example extends Activity {
    /** Called when the activity is first created. */
    private RadioGroup rgroup;
     RadioButton rb;


    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.example);


        rgroup = (RadioGroup)findViewById(R.id.rg);
        final RadioButton[] rb = new RadioButton[5];
        for (int i = 0; i < 5; i++) {
            rb[i]=new RadioButton(this);
            rb[i].setText("rdo"+i);
            rb[i].setId(i);
            rgroup.addView(rb[i]);


        }

    }

    }
