I've used this code to detect keyboard.

view.getViewTreeObserver().addOnGlobalLayoutListener(
                new OnGlobalLayoutListener() {

                    @Override
                    public void onGlobalLayout() {


                            int heightDiff = 

view.getRootView().getHeight()
                                    - view.getHeight();
                            if (heightDiff > 200) {
                                keyboardUp = true;

                                return;
                            }
                            if (keyboardUp) {
                                keyboardUp = false;

                            }
                            Log.e("Keyboard", "" + keyboardUp);
                        }
                    });
