android – issue：指定的子节点已经有父节点.您必须首先在孩子的父母上调用removeView()

概述我开发应用程序以将动态数据添加到多个表视图.结构如下. 我在onPostExecute中的代码是： protected void onPostExecute(List<String> results){int ind,i = 0;ScrollView sv=null;TableLayout tl=null;TableRow tr = null;int mjsonlength=result 我开发应用程序以将动态数据添加到多个表视图.结构如下.

我在onPostExecute中的代码是：

}

循环变量值对于两个循环都应该相同Inorder获取相应产品的子产品.我正在与上述错误作斗争.任何有想法的人.Plz建议我适当的解决方案.谢谢提前.

编辑：

ArrayList<String> productname=new ArrayList<String>();ArrayList<String> description=new ArrayList<String>();ArrayList<String> indexTitle=new ArrayList<String>(); ArrayList<String> mStrings = new ArrayList<String>();

在doINBackground下：

JsONObject Json = array.getJsONObject(i);     manjson = Json.getJsONObject("product");     mStrings.add(manjson.getString("productimage"));     productname.add(manjson.getString("productname"));    indexTitle.add(manjson.getString("subcategoryID"));    description.add(manjson.getString("description"));

解决方法 好的第二个潜在问题也是：
indextl.addVIEw(indextr);

indextr会在每次循环迭代中添加,但它是相同的视图.您只能将一次视图添加到层​​次结构中.您可能希望每个循环迭代都有一个新实例.我不能肯定地说,但这可能是问题所在.
