求解救啊

左右滑动当滑动到WebView的时候WebView是自动撑大（有点像向上滑动操作）在往下滑动没有任何反应，在滑动到ListView在回来问题依然存在

大神你好，我使用的是ViewPagerSimpleActivity的示例来改的，在placeholderheaderlayout.class中updatePlaceHeight函数中的下面这段代码：
`placeHolderView.post(new Runnable() {
@OverRide
public void run() {
ViewGroup.LayoutParams params = placeHolderView.getLayoutParams();

                if (params != null) {
                    params.height = placeHoderHeight;
                    placeHolderView.setLayoutParams(params);
                }
            }
        });`

发现params有时候会返回null,这样的情况下，导致viewpager中listview是直接显示到了屏幕顶端，也就是headerview设置高度不成功。不知道是我在使用过程中因为修改了别的什么逻辑而导致 出现这样的问题。还是本身就存在 这个问题。于是我将上面这段代码修改为：
`placeHolderView.post(new Runnable() {
@OverRide
public void run() {
ViewGroup.LayoutParams params = placeHolderView.getLayoutParams();

                if(params == null){
                    params = new AbsListView.LayoutParams(
                            AbsListView.LayoutParams.MATCH_PARENT, 
                            AbsListView.LayoutParams.WRAP_CONTENT);
                }

                if (params != null) {
                    params.height = placeHoderHeight;
                    placeHolderView.setLayoutParams(params);
                }
            }
        });`

显示就正常了。
