1-) Android RMOS - açık olan klavyeyi kapatma veya açma

implementation 'net.yslibrary.keyboardvisibilityevent:keyboardvisibilityevent:3.0.0-RC2'

public void klavyeListener() {
    KeyboardVisibilityEvent.setEventListener(
        getActivity(),
        new KeyboardVisibilityEventListener() {
            @Override
            public void onVisibilityChanged(boolean isOpen) {
                klavyeSondurum=isOpen;
            }
        });

}

boolean klavyeSondurum=false;

public void klavyeKapat() {
    if(klavyeSondurum){
        getActivity().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);
        InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY, 0);
    }
}

public void klavyeAc() {
    if(klavyeSondurum==false) {
        getActivity().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);
        InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
    }
}

AŞAĞISI ESKİ

public void MyKlavyeKapat() { // 1 sn sonra klavyeyi kapatır
    Handler handler = new Handler();
    handler.postDelayed(new Runnable() {
        @Override
        public void run() {
            getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);
            InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY, 0);
        }
    }, 1000);
}

2-) klavye açma ve kapatma -> burada klavye açıksa kapatıo , kapalıysa açıo tam anlamadım ama kullanılabilir

public void MyKlavyeKapat() {
    c.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);
    InputMethodManager imm = (InputMethodManager) c.getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY, 0);
}

public void MyKlavyeAc() {
    c.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);
    InputMethodManager imm = (InputMethodManager) c.getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.toggleSoftInput(InputMethodManager.SHOW_FORCED,0);

}
