I am creating a POC for simple search functionality in my channel. I am able to Show the search popup as required when I am pressing ok on the input area of search screen it is showing the keyboard screen according to expectation.
But when I am closing the keyboard by pressing Ok or Cancel button the Keyboard screen doesn’t close. I just go at back of the search screen and when I close the search screen it closes the keyboard screen.
To sea the behaviour I have just make 2 more methods for showKeyboard
showKeyboard2() and showKeyboard3()
and I am surprise when I call them in place of showKeyboard() like:
when I call showKeyboard2() method it never shows the keyboard which is absolutely correct behaviour
but when I call showKeyboard3() it opens the keyboard but after 5 seconds it again takes the keyboard in back of the search in place of closing it.
Please have a look of my code I am giving with this post and suggest that what should I do to close the keyboard successfully.
