Android radiogroup, divider between radiobuttons

android, divider, radio-button, radio-group

Solution

<RadioGroup
    android:id="@+id/location_radio_group"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:divider="?android:attr/dividerHorizontal"
    android:showDividers="middle">
</RadioGroup>

That will work for you. And I am really curious how you add view into Group View? That should cause classcastexception, no ?

Problem

Is there a simple way to add a divider between `RadioButtons` inside a `RadioGroup`? I've tried using the `divider` xml attribute and it doesn't seem to be working. In case it's relevant, the `RadioGroup` in my layout does not contain any child views; I'm adding the `RadioButtons` programmatically. EDIT: Problem solved. You can add views besides `RadioButton` inside `RadioGroup` in the xml. In my case, you can also do it programmatically, but be careful about your layout params. Akki had the right idea, and this worked for me: ``` for (int i = 0; i < items.size(); i++) { if (i > 0) { // add a divider with height of 1 pixel View v = new View(this); v.setLayoutParams(new RadioGroup.LayoutParams(LayoutParams.MATCH_PARENT, 1)); v.setBackgroundColor(android.R.color.darker_gray); mRadioGroup.addView(v); } RadioButton rb = new RadioButton(this); /* set other properties ... */ mRadioGroup.addView(rb); } ```
