我想使用facebook登录按钮但不通常它会自动登录,我想让它自动退出并且用户按下它然后登录过程开始,我知道它是自动登录因为我登录了我的机器人facebook应用程序。

实际上,如果我正确地理解了这个问题,那么你想要与穆罕默德·阿米尔里所发布的相反。应该是这样的:
OnCreate方法中的:
Session activeSession = Session.getActiveSession();
//Checks for an open session
if (!(activeSession == null || activeSession.getState().isClosed())) {
//if found one, kill it.
activeSession.closeAndClearTokenInformation();
}
LoginButton authButton = (LoginButton) layout.findViewById(R.id.authButton);
authButton.setReadPermissions(Arrays.asList("basic_info", "email"));
如果有人知道更好的方法来完成同样的事情,我非常想知道(因为我现在面对这个问题)。比如,如何防止Facebook在创建按钮时检查打开的会话。

In onCreate method.
Session activeSession = Session.getActiveSession();
if (activeSession == null || activeSession.getState().isClosed()) {
activeSession = new Session.Builder(context).setApplicationId(context.getString(R.string.app_id)).build();
activieSession = Session.setActiveSession(activeSession);
}
Settings.addLoggingBehavior(LoggingBehavior.INCLUDE_ACCESS_TOKENS);
LoginButton login = (LoginButton)findViewById(R.id.login);
login.setReadPermissions(Arrays.asList("user_groups", "user_photos"));
@Override
public void onResume() {
super.onResume();
// For scenarios where the main activity is launched and user
// session is not null, the session state change notification
// may not be triggered. Trigger it if it's open/closed.
Session session = Session.getActiveSession();
if (session != null && (session.isOpened() || session.isClosed()) ) {
onSessionStateChange(session, session.getState(), null);
}
uiHelper.onResume();
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
uiHelper.onActivityResult(requestCode, resultCode, data);
Session.getActiveSession().onActivityResult(this, requestCode, resultCode, data);
}
