XML PopupMenu.show() Android 上的二进制 XML 膨胀错误
Binary XML Inflate Error on PopupMenu.show() Android
我正在尝试在长按 RecylerView 项目时为 rename/delete 选项扩充一个简单的 PopupMenu。出于某种原因，我在将 xml 文件加载到充气机后调用 mPopup.show() 时收到 XML 充气错误。
我在我的应用程序的其他地方使用类似的逻辑来制作 PopupMenu，它工作正常。我什至尝试将工作的 PopupMenu 从应用程序的不相关部分加载到这个 inflater 中，我在 logcat 中看到相同的 android.view.InflateException: Binary XML file line #17: Failed to resolve attribute at index 1 错误，所以也许 XML 文件不是有问题吗？
如何让这个 PopupMenu 展开并显示自己？

此处直接问题的原因 - InflateException - 将应用程序 Context 用于 appcompat-v7 PopupMenu。
mContext = getActivity().getApplicationContext();
...
PopupMenu mPopup = new PopupMenu(mContext, anchorView);
Context 不会为 v7 小部件设置正确的主题资源，从而导致 InflateException。不过，Activity 确实有合适的主题，使用它可以解决特定问题。
mContext = getActivity();
然而，在修复该问题之后，由于 PopupMenu 从 PopupWindow 传递了锚点 View，因此出现了 WindowManager$BadTokenException。弹出窗口必须锚定到顶级 Window 中的 View，并且 Popup* classes 基本上是简单的 Views，因此是异常。
一个简单的解决方案是用 Dialog 替换 PopupWindow，它确实有 Window。例如：
AlertDialog dlg = new AlertDialog.Builder(getActivity()).setView(mPopupView).show();
最后，我建议您修改设置以消除 Fragment class 中对 static 成员的需要。那些 static 字段可能会导致内存泄漏，您的 IDE 现在很可能会警告您。类似于 CustomChordAdapter 中的侦听器界面就足够了。
