判断软键盘显示还是隐藏

 InputMethodManager imm = (InputMethodManager) mActivity.getSystemService(Activity.INPUT_METHOD_SERVICE);                if (imm.hideSoftInputFromWindow(holder.itemView.getWindowToken(), 0)) {                    imm.showSoftInput(holder.itemView, 0);                    //软键盘已弹出                    System.out.println("软键盘弹出");                    closeSoftKeyboard();                } else {                    //软键盘未弹出                    System.out.println("软键盘未弹出");                }
