Question

我有一个图像按钮，在按下时会显示一个弹出菜单。

public void showMenu (View v){
    PopupMenu popup = new PopupMenu(getBaseContext(), v);
    popup.getMenuInflater().inflate(R.menu.menu_launch_page, popup.getMenu());
    popup.show();

}

生成的菜单背景较暗。如何设置弹出窗口的样式，以便更改背景颜色以及选择项目时的颜色。我正在使用android:Theme.Holo.Light.NoActionBar，因此任何地方都不会涉及Actionbar。

Answer 1

好的，你可以在这里尝试这个，你也可以设置自定义适配器

yourButtonViewObject是您单击以显示此弹出窗口的按钮

ListPopupWindow listPopupWindow = new ListPopupWindow(
            ListPopupWindowAppActivity.this);

//here you can set your custom adapter aswell
        listPopupWindow.setAdapter(new ArrayAdapter(
            ListPopupWindowAppActivity.this,
            R.layout.list_item, passyourarrayhere));
        listPopupWindow.setAnchorView(yourButtonViewObject);
        listPopupWindow.setWidth(300);
        listPopupWindow.setHeight(400);

listPopupWindow.setModal(true);
        listPopupWindow.setOnItemClickListener(
            ListPopupWindowAppActivity.this);

//when you click on yourButtonViewObject show listPopupWindow like this
listPopupWindow.show();

//and in onItemClick overiden method do similar as you do in listview

我就这样做了：

<style name="PopupMenu">
    <item name="android:itemBackground">@color/background_medium_gray</item>
    <item name="android:background">@android:color/transparent</item>
    <item name="android:textColor">@android:color/black</item>
    <item name="android:colorBackground">@color/BackgroundGray</item>
    <item name="android:dividerHeight">1dp</item>
</style>

Context context = new ContextThemeWrapper(getActivity(), R.style.PopupMenu);
final PopupMenu popupMenu = new PopupMenu(context, view);

final MenuInflater menuInflater = popupMenu.getMenuInflater();

样式自定义弹出菜单
