I'm not wrong. But it seems you aren't wrong either! I was consulting the source. It's definitely a CheckedTextView. I just confirmed it with the Hierarchy Viewer; there's no discrepancy.
But I definitely see the radio button icon. Here's what's going on: The layout: <CheckedTextView xmlns:android="http://schemas.android.com/apk/res/ android" android:id="@android:id/text1" android:layout_width="fill_parent" android:layout_height="?android:attr/listPreferredItemHeight" android:textAppearance="?android:attr/textAppearanceLarge" android:gravity="center_vertical" android:checkMark="?android:attr/listChoiceIndicatorSingle" android:paddingLeft="6dip" android:paddingRight="6dip" /> The applicable theme element: <item name="listChoiceIndicatorSingle">@android:drawable/btn_radio</ item> And the drawable (a selector, as expected): <selector xmlns:android="http://schemas.android.com/apk/res/android";> <item android:state_checked="true" android:state_window_focused="false" android:drawable="@drawable/btn_radio_on" /> <item android:state_checked="false" android:state_window_focused="false" android:drawable="@drawable/btn_radio_off" /> <item android:state_checked="true" android:state_pressed="true" android:drawable="@drawable/btn_radio_on_pressed" /> <item android:state_checked="false" android:state_pressed="true" android:drawable="@drawable/btn_radio_off_pressed" /> <item android:state_checked="true" android:state_focused="true" android:drawable="@drawable/btn_radio_on_selected" /> <item android:state_checked="false" android:state_focused="true" android:drawable="@drawable/btn_radio_off_selected" /> <item android:state_checked="false" android:drawable="@drawable/ btn_radio_off" /> <item android:state_checked="true" android:drawable="@drawable/ btn_radio_on" /> </selector> I didn't have the API demo on my device or in my Eclipse at the time, so I checked the source, especially since you cited the layout rather than the visual effect. So it can be a checkmark if you override the theme... It's completely unclear to me why both CheckedTextView and RadioButton exist. RadioButton seems to implement all the functionality of CheckedTextView, plus a bit more protocol due to CompoundButton. Does anyone have any idea why?
