InputMethodManager inputManager = (InputMethodManager)            
            this.         


        

Answer 1

The main problem is in

getCurrentFocus().getWindowToken()

Here getcurrentFocus() is the issue. This problem can be solved easily through providing a valid view residing on your current screen like

yourButtonOnScreen.getWindowToken()

That button wo'nt be null as that is showing on your screen so it will resolve the issue.

Still if you do'nt have any valid view on your screen the just replace

getCurrentFocus().getWindowToken()...

with

//in case of fragment

new View(getActivity()).getWindowToken()

//in case of activity

new View(this).getWindowToken()

hope this will resolve the issue..good luck!
