I have an Activity with Tabs set up with a ViewPager, in one of the Fragments there's an EditText which opens soft input keyboard when the Activity starts, which isn't something I want. I've been trying to hide it but when I'm trying to get a WindowToken it's always null -- on the EditText itself, on the root view of the Fragment, on the ContentView of the parent activity (I tried findViewById(android.R.id.content) with and without getDecorView(), with and without getRootView()), on every View I get from ContentView with getChildAt(). getCurrentFocus() also returns null.
Also, I tried getting the parent Activity both from getActivity() and from a reference I keep in my Application class, and they work the same.
My ultimate goal is to hide the keyboard, or not show it at all unless the user explicitly calls it. If I have to find a way to get a WindowToken for that, I'd like to do that, but if there's another way to hide the keyboard, I'll be happy to try that too.
I'd like to know why the question was downvoted. I can't improve it if I don't know the reason.
