At the bottom of this PreferenceActivity, the "Select ringtone" has an icon/button on the right side.
And "Vibrate" does not.
This Vibrate Preference is one custome Preference extends Preference.
I want to put the same Icon in the Vibrate row. One way is to extends ListPreference or RingtonePreference to cheat OS.
I don't like this, wondering if there is a better solution.

<!-- Layout used by PreferenceScreen. This is inflated inside
android.R.layout.preference. -->
<ImageView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="4dip"
android:layout_gravity="center_vertical"
android:background="@drawable/btn_circle"
android:src="@drawable/ic_btn_round_more" />
I added prefix "android" as:
android:background="@android:drawable/btn_circle"
android:src="@android:drawable/ic_btn_round_more"
Now, Eclipse says: Error: Resource is not public. I googled but no luck. Any thought how to break through?
When you create your preference xml file, you can specify a custom layout for a preference, and you can put an icon in it. The easiest way to do that is to look in the Android SDK folder: platforms/data//res/layout/ (I believe this it) contains the actual layout files used for the different preference types: you can probably copy one of them from there and use that as the basis of your own custom preference.
