根据这个
http://www.google.com/design/spec/components/menus.html#menus-simple-menus,第一个菜单项与原始行的垂直中心对齐,如下所示:
我正在尝试为ListView项创建此菜单,如下所示:
@Override
public void onListItemClick(ListView l, View v, final int position, long id) {
PopupMenu popup = new PopupMenu(getContext(), v, Gravity.CENTER_HORIZONTAL);
popup.getMenuInflater().inflate(R.menu.bus_line_popup, popup.getMenu());
popup.setOnMenuItemClickListener(...);
popup.show();
}
如何使菜单完全按照要求显示?
最佳答案 我做了一点搜索,参见:
http://developer.android.com/reference/android/widget/PopupMenu.html
A
PopupMenu
displays aMenu
in a modal popup window anchored to a
View. The popup will appear below the anchor view if there is room, or
above it if there is not. If the IME is visible the popup will not
overlap it until it is touched. Touching outside of the popup will
dismiss it.
正如doc所说,当有空间时它似乎是正常的,它将显示在视图下方(就像你的情况一样),如果没有roow,它将显示在视图上方.
