我正在使用“使用Google登录”的启动页面.当用户有多个帐户时…在他们选择要登录的帐户后,我正在尝试启动应用程序主要活动,但由于某种原因,我的片段中从未调用过onActivityResult.
我是Activity,我调用onActivityResult并让它调用super以便片段可以处理它,但它永远不会触发.
有什么建议?
这是有问题的片段:

if (!mGoogleapiclient.isConnected()) {

}
} else if (requestCode == RC_LOGGED_IN) {
if (resultCode == RC_SIGN_OUT) {
signOut();
}
}
super.onActivityResult(requestCode,resultCode,data);
}
}
最佳答案
关键是在第一个活动中调用以下方法.
@Override
protected void onActivityResult(int requestCode,Intent data) {
super.onActivityResult(requestCode,data);
}
