Yes, I know that my try catch was wrong, but I corrected it eventually...
I think you are right the error is always displayed when I press the button
a second time...but that brings me to two new problems or questions:
1. Why doesn't the inflated View or layout show up?
2. How can I allow the button to be clicked several times and every time
calling the ViewStub and its inflated layout. (I already changed inflatedId
to NO_ID, but apparently that doesn't do the trick)
<ViewStub
android:id="@+id/stub_exposure"
android:inflatedId="@+id/NO_ID"
android:layout="@layout/exposureview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#77000000">
</ViewStub>
