How to add vertical line to RemoteView for custom Android Notifications?

Question

I'm struggling to add a vertical line to a custom Android Notification. I've tried adding a view like this to my Relative Layout:

<View
    android:id="@+id/line_vertical"
    android:layout_width="1dip"
    android:layout_height="fill_parent"
    android:layout_centerVertical="true"
    android:layout_toRightOf="@id/image_logo"
    android:background="#0000FF" />

But when I fire the notification, I get the following Exception:
android.app.RemoteServiceException: Bad notification posted from package XXX: Couldn't expand RemoteViews for: StatusBarNotification(package=XXX)

Anybody have any ideas?

Answer 1

You can't inflate just any view in a RemoteView. Change your View to an empty TextView or ImageView.

A RemoteViews object (and, consequently, an App Widget) can support the following layout classes:

FrameLayout
LinearLayout
RelativeLayout

And the following widget classes:

AnalogClock
Button
Chronometer
ImageButton
ImageView
ProgressBar
TextView
ViewFlipper
ListView
GridView
StackView
AdapterViewFlipper

Descendants of these classes are not supported.
