有两件事：

第一：

将myHolder.itemView.setBackgroundColor(Color.SOME_COLOR);更改为((CardView)myHolder.itemView).setCardBackgroundColor(Color.SOME_COLOR);，无论您在何处使用

二：

我想，在将应用程序上传到Play Store之前，您已经很好地测试了它。这意味着错误与发行版apk有关。通常，当我们构建一个签名的apk时，ProGuard会尝试缩小代码，包括外部库。有时会导致撞车。

因此，您可以做的是将所有外部库排除在ProGuard小型化过程之外。为您的模块查找名为proguard-android.txt的文件。再加上以下内容，

代码语言：javascript
运行
复制
-keep class org.** { *; }
-keep interface org.** { *; }
-keep enum org.** { *; }

这将排除包名以org开头的所有类/接口/枚举。对所有外部库也这样做。再次构建签名版本apk。确保您使用签名的apk来测试应用程序，而不是使用调试程序。

把这个加到你的护卫档案里，

代码语言：javascript
运行
复制
-keep class com.android.** { *; }
-keep interface com.android.** { *; }
-keep enum com.android.** { *; }

-keep class com.github.** { *; }
-keep interface com.github.** { *; }
-keep enum com.github.** { *; }

-keep class com.squareup.** { *; }
-keep interface com.squareup.** { *; }
-keep enum com.squareup.** { *; }

-keep class com.fasterxml.** { *; }
-keep interface com.fasterxml.** { *; }
-keep enum com.fasterxml.** { *; }

-keep class de.hdodenhof.** { *; }
-keep interface de.hdodenhof.** { *; }
-keep enum de.hdodenhof.** { *; }
