在片段中隐藏键盘

Question

I try to hide the keyboard from within a fragment. The fragment is inside a viewpager.

I use this code, which works fine when running on Android emulator.

 View view = getActivity().getCurrentFocus();
    if (view != null) {
        InputMethodManager imm = (InputMethodManager)getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
    }

On a huawei mate 20 pro device view is always null .

How can I get this working on every device?

Answer 1

I solved it by calling requestFocus() on the edittext before hiding the keyboard.

getView().findViewById(R.id.notes_edittext).requestFocus();

View view = getActivity().getCurrentFocus();
if (view != null) {
   InputMethodManager imm = (InputMethodManager)getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
   imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
}

Maybe its helpfull to someone else.
