Xamarin.Forms MissingMethodException: 'Android.Support.V4.Widget.DrawerLayout.AddDrawerListener' 未找到
Xamarin.Forms MissingMethodException: 'Android.Support.V4.Widget.DrawerLayout.AddDrawerListener' not found
我关注了以下 link 中的所有内容:
https://developer.xamarin.com/guides/xamarin-forms/user-interface/navigation/master-detail-page/
我写的代码可以在这里找到:http://github.com/foyzulkarim/XamarinFormsDrawer
我使用 UWP 项目在我的 Windows 10 本地计算机中成功部署了相同的项目,但是每当我想在模拟器或我的设备中部署时,它都会抛出以下异常。

解决方案是,我需要更新包,只有 Xamarin.Forms 包。就像下图一样。
更新后,packages.config 文件应该如下所示
<?xml version="1.0" encoding="utf-8"?>
<packages>
<package id="Xamarin.Android.Support.Animated.Vector.Drawable" version="23.3.0" targetFramework="monoandroid60" />
<package id="Xamarin.Android.Support.Design" version="23.3.0" targetFramework="monoandroid60" />
<package id="Xamarin.Android.Support.v4" version="23.3.0" targetFramework="monoandroid60" />
<package id="Xamarin.Android.Support.v7.AppCompat" version="23.3.0" targetFramework="monoandroid60" />
<package id="Xamarin.Android.Support.v7.CardView" version="23.3.0" targetFramework="monoandroid60" />
<package id="Xamarin.Android.Support.v7.MediaRouter" version="23.3.0" targetFramework="monoandroid60" />
<package id="Xamarin.Android.Support.v7.RecyclerView" version="23.3.0" targetFramework="monoandroid60" />
<package id="Xamarin.Android.Support.Vector.Drawable" version="23.3.0" targetFramework="monoandroid60" />
<package id="Xamarin.Forms" version="2.3.2.127" targetFramework="monoandroid60" />
</packages>
并忽略下面的其余包。
更新 Xamarin.Forms nuget 包对我不起作用。就我而言,需要更新 Android Studio 才能使 Xamarin.Forms 与 Visual Studio 一起工作。更新后,重新启动 Android Studio 并再次查找更新并在找到时应用它们。您需要不断重复此操作,因为并非所有更新都会一次性安装。至少这是我的情况。
我想这行得通,因为 Android Studio 包含 Android SDK 或 Visual Studio 或 Xamarin 需要的一些其他组件。
只需将您的 nuget-packages 更新到最新版本(Xamarin.forms 也是)
清洁溶液
关闭visualstudio
删除以下所有 .zip 文件:
C:\Users[你用户名]\AppData\Local\Xamarin\zips
重新启动 visualstudio 并重新编译 :) 它将再次下载那些 .zip 文件(可能需要几分钟)。这些 zip 包括相关的 android 支持库。所以它会下载真实的(你引用的 xamarin.forms 版本相关)。
大部分情况需要更新Xamarin.Forms包到最新版本
on all your projects( To avoid Other Exceptions)
对于便携式、.Driod、.IOS和Windows Phone 如果存在,则必须清理您的解决方案并关闭 visual studio 并再次打开它,Finlay 一切都会好起来的。
但在某些情况下,您需要将 Xamarin.Forms 软件包降级为 2.3,而不是 2.5.0.121934
