Android开发 - 解决DialogFragment在全屏时View被状态栏遮住的问题

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    ...
    //此处rootView是对话框的顶层View
    rootView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
        @Override
        public void onGlobalLayout() {
            int[] location = new int[2];
            rootView.getLocationOnScreen(location);
            int y = location[1];
            if (y == 0) {
                //此处的topMarginView是被状态栏覆盖的View
                []()ViewGroup.MarginLayoutParams params
                        = (ViewGroup.MarginLayoutParams)topMarginView.getLayoutParams();
                params.topMargin += BarUtils.getStatusBarHeight();
                topMarginView.setLayoutParams(params);
                rootView.getViewTreeObserver().removeOnGlobalLayoutListener(this);
            }
        }
    });
}
