我们之前为 jellybean to nougat 开发了一个应用程序，但现在我们在 visual studio 中更新我们的 xamarin 后遇到了问题。

以前，我们的 apk 在所有 Android 版本中都能完美运行，但现在更新后，它现在正在崩溃......但仅在 5.1.1 中。我们已经使用 kitkat、lollipop 5.1、marshmallow 和 nougat 对其进行了测试，并且它确实在运行。

我们注意到我们的应用程序在 OnCreate 方法中的最后一个大括号“}”之后崩溃了。它在没有事先详细信息的情况下启动异常。

这个异常的原因是什么？或者任何已经有人解决的解决方案。

我不知道这是否只是由于 xamarin 更新而更改的设置。

在其他5.1和5.1.1版本上测试，仅在OPPO手机上出现异常

异常图像在这里，正如我所说，没有任何细节

这是调试器的输出

    #endregion

}//this is the place where exception occur in 5.1.1 . I don't know why.

如果有一个用户并且是活跃的。它将继续登录。但同样的事情会发生。在 OnCreate() 方法下的 login.cs 最后一个括号会再次崩溃

这是 LogCat 输出，对我来说很难阅读，因为这是我第一次看到它。

这是我以前的风格

<!-- Input Layout -->
<style name="TextLabel" parent="TextAppearance.AppCompat">
  <!-- Hint color and label color in FALSE state -->
  <item name="android:textColorHint">#000000</item>
  <item name="android:textSize">16sp</item>
  <!-- Label color in TRUE state and bar color FALSE and TRUE State -->
  <item name="colorAccent">#0d47a1</item>
  <item name="colorControlNormal">#000000</item>
  <item name="colorControlActivated">#0d47a1</item>
</style>

** 问题已解决 **

按照建议，我可能需要将样式的父级从 TextAppearance.AppCompat 更改为 Widget.Design.TextInputLayout 。我试过了，效果很好!
非常感谢!

只是，我想知道为什么只在 OPPO 5.1.1 中。我试过和工作的其他安卓版本在这里
-棉花糖和牛轧糖与华硕 6.0 和 7.0
-Kitkat 和 Marshmallow Starmobile 4.4 和 6.0
-JellyBean、Kitkat 和 Marshmallow 与三星 4.2、4.4 和 6.0
- 5.1 和 5.1.1 的其他品牌(不是 OPPO)

最佳答案

问题出在您的样式颜色上。

E/AndroidRuntime( 6824): android.view.InflateException: Binary XML file line #24: Error inflating class TextView

.../...

Caused by: java.lang.RuntimeException: Failed to resolve attribute at index 24
E/AndroidRuntime( 6824): at android.content.res.TypedArray.getColor(TypedArray.java:401)

如果来自这里，我假设:

txtAccessCode = FindViewById<TextInputLayout>(Resource.Id.layoutAccessCode);

没有看到你的风格，你可以尝试这样的事情:

For example确保 TextView 继承自 Widget.Design.TextInputLayout:

<style name="TextViewStyle" parent="Widget.Design.TextInputLayout">

并且您已经包含了 Design Support Library 依赖项。

如果您想要更具体的答案，请添加您的样式代码、xml/布局、layoutAccessCode 和构建依赖项。

看看这两个问题的答案:

Android XML: RuntimeException: Failed to resolve attribute at index 6

TextInputLayout: RuntimeException - Failed to resolve attribute at index 24
