我正在尝试使用PopUp菜单创建一个RecyclerView，但每当我尝试访问弹出菜单时，它都会崩溃并说：引起：java.lang.UnsupportedOperationException：无法解析索引1处的属性：TypedValue {t = 0x2 / d = 0x7f01005e a = -1}
我的menu.xml是：
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="@+id/menu1"
android:title="Menu 1" />
<item
android:id="@+id/menu2"
android:title="Menu 2" />
<item
android:id="@+id/menu3"
android:title="Menu 3" />
</menu>
style.xml：
<resources>
<!-- Base application theme. -->
<!-- your theme inherits from the material theme -->
<style name="AppTheme" parent="android:Theme.Material">
<!-- theme customizations -->
<!-- Customize your theme here. -->
<item name="colorPrimary">#000</item>
<item name="colorPrimaryDark">#c21d1111</item>
<item name="colorAccent">#c6897929</item>
</style>
</resources>

答案 0 :(得分：3)
我通过实例将活动而不是上下文传递给PopupMenu（）来解决了这个问题;
