Hi,

I seem to have a bit of an issue with OnPDFDoubleTapped and OnPDFSingleTapped.

If I single tap, only OnPDFSingleTapped is invoked.

If I double tap, OnPDFSingleTapped is invoked followed by OnPDFDoubleTapped.

When I double tap, I only want OnPDFDoubleTapped to be invoked - can you please advice a way around this?

yes, gesture always fire single tap first.

Ok edited my response with more detail.

It's obvious that I use return True / False to get rid of the single press event.

My issue is this : -

My customer wants to single press to show / hide the buttons such that more of the view is available. So I've added some code to facilitate this.

I have added an event to the interface - OnDocumentClicked and fire it via m_listener.OnDocumentClicked().

What test can I perform in the single press event to prevent it from calling this method, because a double press is following?

I have fixed this by adding a handler to the PDFReader class.

I invoke the handler with a postDelayed, using a 100ms delay, upon the OnPDFSingleTapped event firing. When the OnPDFDoubleTapped event fires, if a handler exists, it stops it using removeCallbacks.

Job done, looks great and is nice and responsive.

Can you tell me the exact max delay between two taps that invokes OnPDFDoubleTapped? I need it to set the correct delay for handler.postDelayed() method.
