KeyEvent.KEYCODE_BACK does not work on special button

Question

I need to intercept hide keyboard event. For this, I used onKeyPreIme and dispatchKeyEvent. All good, when I push back button, I intercept this KeyEvent.KEYCODE_BACK. But there are problem devices like meizu. Where there is a special button "hide keyboard", which in turn is not caught in the callback. Can you give advice, how I can achive this?

you can use method onMeasure() in your root view to detect if keyboard was shown or hidden https://stackoverflow.com/a/8135035

It doesn't work with android:windowSoftInputMode="adjustPan". I used ViewTreeObserver – Serega Gevelev Dec 15 '16 at 15:29
