推荐答案

步骤:1)menu.xml定义了所有三个菜单项.登录，注销和共享之后，默认情况下使注销可见性为

step:1) menu.xml define all three menu item. login ,logout and share after that make logout visibility to false by default

android:visible="false"

并使其余两个项目可见.可选，因为默认情况下所有项目在android中都是可见的

and make remaining two items visible.its optional because by default all items are visible in android

步骤:2)当您登录时，Activity会对该xml进行充气，而无需在活动中进行任何更改 此时，我们仅显示登录和共享"菜单项，并且我们已经将xml中的logOff项目可见性设置为false.

Step:2)when you are in login Activity inflate that xml.and no need to make any change in activity at these point we are showing login and share menu item only and we have already made logOff item visibility to false in the xml .

步骤:3)当您处于主要活动(登录活动后显示的活动)时

step:3) when you are in main activity(activity that you are showing after login activity) do these

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {

    inflater.inflate(R.menu.menu, menu);

    MenuItem item = menu.findItem(R.id.login_id);
            item.setVisible(false);//
    MenuItem item = menu.findItem(R.id.logOff_id);
            item.setVisible(true);
    super.onCreateOptionsMenu(menu, inflater);
}

此时，您将获得注销和共享，因为我们已将登录菜单项的可见性设置为false.

at these point you will get logOff and share because we have made login menu item visibility to false .
