android - SoftkeyBoard在android中出现和消失事件

Question

如何查找软键盘可见或不可见的事件。我想在键盘出现并且按下它消失时捕捉事件。我能够捕捉完成按钮按下的事件并且它工作正常。

任何帮助表示赞赏。提前致谢。

final View activityRootView = rellayLoginParent;
        activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new OnGlobalLayoutListener()
            {
                @Override
                public void onGlobalLayout()
                    {
                        Rect r = new Rect();
                        // r will be populated with the coordinates of your view that area still visible.
                        activityRootView.getWindowVisibleDisplayFrame(r);

                        int heightDiff = activityRootView.getRootView().getHeight() - (r.bottom - r.top);
                        //MyLog.w("height difference is", "" + heightDiff);
                        if (heightDiff > 100)
                            { // if more than 100 pixels, its probably a keyboard...
                                /*isKeyBoardVisible = false;
                                linlayAdLayout.setVisibility(View.GONE);*/
                                Log.e("Keyboard Visibilitty","Visible");

                                    {
                                        lytAppHeader.setVisibility(View.GONE);

                                Log.e("Keyboard Visibilitty","InVisible + Gone");
                                if(lytAppHeader.getVisibility() == View.GONE)
                                    {
                                        lytAppHeader.setVisibility(View.VISIBLE);
                                    }
                            }

                    }
            });
