java - Facebook 点赞按钮的说明

Question

我遇到以下问题。我正在尝试为我的 Facebook 页面创建一个“赞”按钮，但我卡住了。我按照说明进行操作，但它不起作用!我没有看到设置此按钮坐标的值。它在哪里？谢谢

EDIT2:我又编辑了一下，现在第一个onActivityResult有这个问题:

void 是变量 onActivityresult 的无效类型

出了什么问题？

Answer 1

void 是变量 onActivityresult 的无效类型，因为您在 onCreate 方法中使用了 onActivityresult 方法。从 onCreate 中删除此方法并调用

likeView.handleOnActivityResult(this, requestCode, resultCode, data);

来自您的 onActivityResult 方法。另请检查您的 LikeView 变量名称，它在您使用的任何地方都应该相同。
