Java，（语法错误，插入＆＃34; AssignmentOperator表达式＆＃34;完成）

Question

我使用Java使用Eclipse，

此代码有什么问题？

我收到此错误"Syntax error, insert "AssignmentOperator Expression" to complete "

{
  public void onCreateContextMenu(ContextMenu paramAnonymous2ContextMenu, View paramAnonymous2View, ContextMenu.ContextMenuInfo paramAnonymous2ContextMenuInfo)
      {
          ((AdapterView.AdapterContextMenuInfo)paramAnonymous2ContextMenuInfo);//**Syntax error, insert "AssignmentOperator Expression" to complete**
                        paramAnonymous2ContextMenu.add(0, 0, 0, "Delete");
      }
});

Answer 1

这不是有效的陈述，您可能会尝试将其分配给

((AdapterView.AdapterContextMenuInfo)paramAnonymous2ContextMenuInfo);

像

AdapterView.AdapterContextMenuInfo someRef = ((AdapterView.AdapterContextMenuInfo)paramAnonymous2ContextMenuInfo);

Answer 2

((AdapterView.AdapterContextMenuInfo)paramAnonymous2ContextMenuInfo)不是有效的陈述;它没有做任何事情。

我怀疑你打算这样做：

((AdapterView.AdapterContextMenuInfo)paramAnonymous2ContextMenuInfo).add(0, 0, 0, "Delete");
