How to check visibility of software keyboard in Android?

Question

I need to do a very simple thing - find out if the software keyboard is shown. Is this possible in Android?

Answer 1

99% of solutions here are based on probability of IME WINDOW SIZE and each such solution is a sh... worth!

because:

1. OVERLAYS - from User apps or System apps
2. IME have no MINIMUM SIZE it can take 100% of window size and can be so thin as imagination of developer implementation :)
3. MODAL windows / MULTI windows
4. and many many more like no knowledge of IPC (eg: foreign window or its content detection)

so guessing it's IME is always wrong - don't guess be sure !!!

@kevin-du is best solution wright now as its query IMM for IME height - but as it said the method is hidden API so using it could be dangerous in the way of getting wrong "false negative results" - by wrong dev usage.
