提问by Ameya Savale
I am trying to create a nested class in order to use the AsyncTask, however eclipse gives me an error on the class SendData saying "Syntax error on token "class", invalid type" why is it giving me that error?
我正在尝试创建一个嵌套类以使用 AsyncTask，但是 eclipse 在类 SendData 上给了我一个错误，说“令牌“类”上的语法错误，无效类型”为什么它给了我那个错误？

回答by PermGenError
sendData() is a method syntax, not a class
sendData() 是一种方法语法，而不是一个类
private class SendData() extends AsyncTask<Void, Void, Void>{
should be
应该
private class SendData extends AsyncTask<Void, Void, Void>{
回答by kosa
private class SendData()
You have both methodand classsyntax here. Not sure which one you want.
你在这里有method和class语法。不确定你想要哪一个。
If you want to define a class then remove ()
如果你想定义一个类然后删除 ()
