Okay found the problem, I simply forgot to define the button's
View btnExposure = (ImageButton) findViewById(R.id.button_exposure);
So this - quite simple - problem's solved, but now I got at new
NullPointerException at
com.mobilevideoeditor.moved.EditorView$1.onClick(EditorView.java:54), which
is importStub = ((ViewStub) findViewById(R.id.stub_exposure)).inflate();
And this is what I don't really understand because I am not familiar with
ViewStubs yet...
I also tried ViewStub stub = (ViewStub) findViewById(R.id.stub_exposure);
importStub = stub.inflate();
but again I get the Null Pointer Exception at importStub = stub.inflate();
Could there be s.th wrong with the exposureview.xml that I use to inflate
the stub??
