。但问题是src在片段内的if上也可见。我不希望片段具有片段工具栏的let image = startingImageView.image
let w = image.size.width
let h = image.size.height
print("image width: ", w)
print("image height: ", h)
var height = 0
if (w > h) { //landscape
height = (self.startingFrame!.height / self.startingFrame!.width) * keyWindow.frame.width
} else { //portrait
height = (self.startingFrame!.height / self.startingFrame!.width) * keyWindow.frame.height
}

setHasOptionsMenu(true) 中的 onCreate();
onCreateOptionsMenu中的
对您的片段菜单进行了充气，并使用MainActivity中的menu.removeItem(R.id.menu_id_to_be_removed);删除onPrepareOptionsMenu
答案 1 :(得分：0)
对于您不希望onCreateOptionsMenu的片段，在这些片段中包含以下代码
@Override
public void onCreate(@Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(false);
}
