How to remove RadioButton circle in Android 4.4.4

Question

I made a custom RadioButton that looks as follow in a Android 5.0 device.

These RadioButtons are dynamic created as shown in the follow methods. So the first method redioButtonPresenterApparence sets its appearance removing circle (setting buttonDrwable to null. The second method set the buttons background later.

private void radioButtonPresenterApparence(RadioButton presenter, int icon) {
    Drawable drawable = getResources().getDrawable(icon);
    presenter.setCompoundDrawablesWithIntrinsicBounds(drawable, null, null, null);
    presenter.setButtonDrawable(null);
    presenter.setGravity(Gravity.CENTER);
}

private void updateButtonsBackground(){
    int childCount = getChildCount();
    BackgroundSelector bgSelector = new BackgroundSelector(childCount);
    for(int i = 0; i < childCount; i++){
        View rb = getChildAt(i);
        rb.setBackgroundResource( bgSelector.getBackgroundResource(i) );
        rb.requestLayout();
    }

    requestLayout();
}

My problem is when testing the same on Samsung Android 4.4.4 devices (not sure about other manufactories), it shows as follow.

PS: It's a code created RadioButton. You can check it in the follow method:

private void addPresenter(int icon){
    RadioButton presenter = new RadioButton(getContext());  //Create new RadioButton
    radioButtonPresenterApparence(presenter, icon);         //Set icon and configure aparence
    addView(presenter);                                     //Add new button to Selector
    presenterParentAparance(presenter);                     //Config button inside parent
    requestLayout();                                        //Request layout update to Selector
}

Find your radio buttons in layout.xml and give them this:

android:button="@null"

This should do the same thing as presenter.setButtonDrawable(null); Except that this actually works

Edit:

In case of code created button, please use:

presenter.setButtonDrawable(new StateListDrawable());

Actually helps as it is an equivalent of

android:button="@null"
