Hello SDK developers
I finally did get a reply for the problem below and I am being told
this
The problem is that the only Window implementation (PhoneWindow) uses
a LayoutInflater in its setFeatureInt method and instantiates the new
layout with inflate and attachToRoot=true. Consequently, when you call
setFeatureInt, the new layouts are not replaced but attached to the
internal title container and thus drawn on top of each other.
You can workaround this by using the a helper method instead of
setFeatureInt. The helper simply removes all views from the internal
title container before the new custom title feature is set
I did not find this documented in any of the javadocs or in any
references. Is setFeatureInt intended to behave like this?
This is the method I am using in order to remove all views from the
title. It works fine. Can anyone please confirm if this is the correct
way to remove views from the title or an undesirable hack likely to
change in the future updates. Thanks a lot.
private void setCustomTitle(int value) {
try {
// retrieve value for
com.android.internal.R.id.title_container
int titleContainerId = (Integer) Class.forName(
"com.android.internal.R$id").getField
("title_container").get(null);
// remove all views from titleContainer
((ViewGroup) getWindow().findViewById
(titleContainerId)).removeAllViews();
// add new custom title view
getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, value);
} catch(Exception ex) {}
}
