是否有可能显示一个PopupMenu的图标？ [英] Is it possible to display icons in a PopupMenu?

问题描述

我真的很喜欢新的PopupMenu我们得到了3.0，但我就是无法显示任何图标旁边，它的菜单项。我膨胀的菜单从以下的.xml：

I really like the new PopupMenu we got in 3.0, but I just can't display any icons next to the menu items in it. I'm inflating the menu from the .xml below:

<item android:id="@+id/menu_delete_product"
    android:icon="@drawable/sym_action_add"
    android:title="delete"
    android:showAsAction="ifRoom|withText" />

<item android:id="@+id/menu_modify_product"
    android:icon="@drawable/sym_action_add"
    android:title="modify"
    android:showAsAction="ifRoom|withText" />

<item android:id="@+id/menu_product_details"
    android:icon="@drawable/sym_action_add"
    android:title="details"
    android:showAsAction="ifRoom|withText" />

通过这个code：

image.setOnClickListener(new View.OnClickListener() {
                        @Override
                        public void onClick(View v) {
                            PopupMenu pop = new PopupMenu(getActivity(), v);
                            pop.getMenuInflater().inflate(R.menu.shelves_details_menu, pop.getMenu());
                            pop.show();
                        }
});

我不能得到的图标显示出来，我失去了一些东西？

I can't get the icons to show up, am I missing something?

感谢

推荐答案

如果你愿意成为一个有点冒险，看看谷歌的源头code的弹出菜单。创建你自己的类，即MyPopupMenu是一样的谷歌的PopupMenu的类，但做一个细微的变化。

If you're willing to be a bit adventurous, look at Google's source code for PopupMenu. Create your own class i.e. MyPopupMenu that is the same as Google's PopupMenu class, but make one slight change.

在PopupMenu的构造函数：

In PopupMenu's constructor:

public MyPopupMenu(Context context, View anchor) {
    // TODO Theme?
    mContext = context;
    mMenu = new MenuBuilder(context);
    mMenu.setCallback(this);
    mAnchor = anchor;
    mPopup = new MenuPopupHelper(context, mMenu, anchor);
    mPopup.setCallback(this);
    mPopup.setForceShowIcon(true); //ADD THIS LINE

}

使用的方法setForceShowIcon，迫使它显示的图标。你也可以公开公共方法来设置该标志，以及根据您的需求。

use the method setForceShowIcon to force it to show the icon. You can also just expose a public method to set this flag as well depending on your needs.
