推荐答案

您可以使用以下属性来更改PopupMenu的位置: 重力， dropDownHorizo​​ntalOffset 和 dropDownVerticalOffset

You can change your PopupMenu's position by using the following attributes: gravity, dropDownHorizontalOffset and dropDownVerticalOffset

首先将重力设置为重力".

First set gravity to Gravity.END

popup.setGravity(Gravity.END);

然后通过创建样式来更改下拉偏移

Then change your dropdown-offsets by creating a style

<style name="MyPopupMenu" parent="@style/Widget.AppCompat.PopupMenu">
    <item name="android:dropDownHorizontalOffset">-4dp</item>
    <item name="android:dropDownVerticalOffset">4dp</item>
</style>

如果要与锚点视图重叠，请使用

If you want to overlap the anchor view use

parent="@style/Widget.AppCompat.PopupMenu.Overflow"

最后将MyPopupMenu应用于主题

Lastly apply MyPopupMenu to your theme

<item name="popupMenuStyle">@style/MyPopupMenu</item>
