动态计算高度 getLocationOnScreen(location) 当前控件距离屏幕坐标系的绝对坐标 0为x 1为y，控件坐标系默认左上角 ， DialogFragment 默认是状态栏高度的。

int[] location = new int[2];
binding.clType.getLocationOnScreen(location);
homeTypeFilterBottomFragment.setWINDOWPARAMS_Y(location[1] + binding.clType.getHeight() - StatusBarTool.getStatusBarHeight(requireActivity()));
homeTypeFilterBottomFragment.show(getChildFragmentManager(), HomeTypeFilterBottomDialog.class.getName());
