关于ViewGroup 中listview 和GridView数据不能动态更新的解决

原文来自此网站 http://www.pocketdigi.com/20120701/881.html @Overrideprotected void onLayout(boolean changed, int l, int t, int r, int b) {// if (changed) {int childLeft = 0;int childCount = getChildCount();for (int i = 0; i < childCount; i++) {View childView = getChildAt(i);if (childView.getVisibility() != View.GONE) {int childWidth = childView.getMeasuredWidth();childView.layout(childLeft, 0, childLeft + childWidth,childView.getMeasuredHeight());childLeft += childWidth;}}// }}

将if(changed) 注释掉就可以及时刷新 listview、gridview 数据
