我正在使用为 facebook im 提供的 facebook android sdk，使用他们提供的示例 - 简单，并且工作得非常好，现在登录 fb 时显示来自 fb 的表单以在按钮单击时发布到墙上。但是我想直接从代码中设置文本，然后单击按钮直接将我设置的文本发布到 fb 上，而无需调用墙贴表单来输入文本并分享。
这是我的项目图片，包含我正在使用的所有 fb 相关文件，下面是这个项目的 mu step wise o/p
1.登录
在 clcik 显示分享表格后
但是在墙贴之后我想直接在fb上上传我的帖子我该怎么做以及改变什么我不知道我试过但无法设置我的预定义文本，如何可以直接在墙上发布而不调用表单来分享我已经从这个链接下载了 sdk fron gitstore https://github.com/facebook/facebook-android-sdk/ 请帮助我提前感谢
这是我的 example.java 代码
