每次按菜单按钮时，两次onMenuOpened/onPanelClosed回调 [英] Double callbacks onMenuOpened/onPanelClosed on each menu button press

问题描述

在我的Android应用中，我想收集有关打开(和关闭)(三个点)操作栏菜单的时间(多长时间)(不选择任何项)的统计信息.对于此任务，我已经覆盖了Activity中的onMenuOpened和onPanelClosed方法.但是，到目前为止，在所有设备(Android 4.4、4.2； Samsung和HTC)上，我都尝试过一次，每次打开和关闭菜单时，这些方法都会触发两次. 这是一个错误吗?有没有其他方法可以监视此菜单的打开和关闭?

In my Android app I want to collect statistics on when (how often) the overflow (three dots) action bar menu is opened and closed (without an item being selected). For this task I have overriden onMenuOpened and onPanelClosed methods within an Activity. However, on all the devices (Android 4.4, 4.2; Samsung and HTC) I've tried this so far these methods are triggered twice, each time the menu is opened and closed. Is this a bug? Is there another way to monitor this menu opening and closing?

推荐答案

您可以尝试一下...我已经对其进行了测试....它非常完美....

you can try this...i have tested it ....it works perfect....

@Override
public void onActivityCreated(Bundle savedInstanceState) {
    Activity activity = getActivity();
    activity.getActionBar().addOnMenuVisibilityListener(new OnMenuVisibilityListener() {
    @Override
        public void onMenuVisibilityChanged(boolean isVisible) {
            // TODO Auto-generated method stub
            //you can check the isVisible boolean to check
            // if the overFlowMenu is visible or not
        }
    });
