今天在实现动态改变布局的时候，报了个Error<android.view.ViewGroup$LayoutParams cannot be cast to android.widget.RelativeLayout$LayoutParams>

仔细去看了下代码，发现自己真的太粗心大意了，记下来，方便日后翻阅。

原代码：

ll_Pop_Params = ll_pop.getLayoutParams();

img_Product_Params = img_product_large.getLayoutParams();

ll_Pop_Params.width = (int) (width * 0.85);
ll_Pop_Params.height = (int) (width * 1.275);

ll_pop.setLayoutParams(ll_Pop_Params);
img_product_large.setLayoutParams(new ViewGroup.LayoutParams((int) (width * 0.85), (int) (width * 0.75)));

修改后：

ll_Pop_Params = ll_pop.getLayoutParams();
img_Product_Params = img_product_large.getLayoutParams();

ll_Pop_Params.width = (int) (width * 0.85);
ll_Pop_Params.height = (int) (width * 1.275);

ll_pop.setLayoutParams(ll_Pop_Params);
img_product_large.setLayoutParams(new RelativeLayout.LayoutParams((int) (width * 0.85), (int) (width * 0.75)));
不能粗心不能粗心，要仔细！
