验证后的facebook集成页面不会进入android中的下一个活动
我正在使用delaroy/AndroidFacebook中的示例尝试在android中进行facebook集成。当我运行代码示例时，它运行完美，因此想到在我的项目中集成，在项目中我使用片段中的facebook登录按钮并给出facebook也在其中初始化。 Facebook页面的网页打开完美，登录，登录后显示消息
。单击确定后，Webview将关闭，而不会进入下一个活动。

我不知道我在哪里失踪，任何人都可以指导我这个。提前谢谢你们。

可能会调用Activity的onActivityResult（）。所以让你的Fragment代码保持不变，只需从活动中调用Fragment的onActivityResult（） -
在您的活动onActivityResult()中，获取对您的片段的引用 -
Fragment f = getFragmentManager.findFragmentById(R.id.container);
其中R.id.container是包含您的片段的Activity的布局。然后触发片段的onActivityResult（） -
((sharelist) fragment).onActivityResult(requestCode, resultCode, data);
不要在Activity中使用CallbackManager，因为它仅在片段中定义。
答案 1 :(得分：0)
在onSuccess()
试试这个：
rotected void getLoginDetails（LoginButton login_button）{
// Callback registration
login_button.registerCallback(callbackManager,
new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult login_result) {
getUserInfo(login_result);
Intent intent = new Intent(getApplicationContext(), HomeActivity.class);
startActivity(intent);
}
