Hello again,
I just wanted to add that the layout.xml:
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android";
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<com.example.RPCPlayerInfoTitle
android:id="@+id/player_info"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</RelativeLayout>
when I changed the layout_width and layout_height to constants, the
addRule works.
another thing I've noticed is that when I don't override onMeasure in
RPCPlayerInfoTitle, myImage is being aligned to the bottom of the
screen. from some strange reason myImage doesn't recognized
RPCPlayerInfoTitle (my custom View) as its parent or ignore its
dimensions.
thanks
