Hello Nermeen,
It doesn't come from the compatible colors of my icon because I have the problem even if I try using your native icons.
Only "ic_action_search" is displaying, and I guess it is a problem with SetBtnEnabled but if I try to put these methods in the PDFViewController constructor, it is still not working:
SetBtnEnabled(btn_find, true);
SetBtnEnabled(btn_return, true);
SetBtnEnabled(btn_summary, true);
I also tried something like this but I got no best result.
btn_find.setVisibility(View.VISIBLE);
btn_return.setVisibility(View.VISIBLE);
btn_summary.setVisibility(View.VISIBLE);
My second question is that I would like to add a onClickListener() to a button that quit the reader (PDFViewAct). A little like onBackPressed method.
