ava.lang.IllegalStateException: The specified child already has a parent. You must call removeView()

今天在做项目遇到一个问题，运行报了如下错误， 看了一下是因为 RelativeLayout 动态添加子View ，要去掉子View 的父容器，才能添加，

具体的解决方法 是：

View view = View.inflate(SettlementActivity.this, R.layout.item_settlement_list, null);

ViewGroup parent = (ViewGroup) view.getParent();
if (parent != null) {
parent.removeAllViews();
}
mRL.addView(view, params);

//报的错误信息
