几乎所有活动都有可供选择的菜单,这些活动是通过执行“CreateOptionsMenu(). 但是,在一个活动中,有一个PopupWindow,当这一PopupWindow(需要适当运作)把菜单打碎时,不会带来选择菜单。
PopupWindows没有CreateOptionsMenu()的功能。 是否有其他办法为PopupWindow增加选择菜单?
或者,是否有办法从活动背后获得选择菜单,以便在用户利用菜单时展示?

我通过拦截菜单钥匙,呼吁就这项活动公开宣布行动。 这里是主要听众:
OnKeyListener mMenuKeyListener = new OnKeyListener() {
@Override
public boolean onKey(View view, int keyCode, KeyEvent event) {
if(keyCode==KeyEvent.KEYCODE_MENU) {
activity.openOptionsMenu();
return true;
} else {
return false;
}
}
};
我认为,你必须补充这一主要听众,听取PopupWindow的每一个观点,以便让它发挥作用。
public void setupMenuKeyListenerRecursive(View v) {
if (v != null) {
try {
ViewGroup viewGroup = (ViewGroup)v;
int childCount = viewGroup.getChildCount();
for (int index = 0; index < childCount; index++) {
View child = viewGroup.getChildAt(index);
setupMenuKeyListenerRecursive(child);
}
} catch (Exception e) {
}
v.setOnKeyListener(mMenuKeyListener);
}
}
