android - 在 RecyclerView 上膨胀类 ImageView 时出错

Question

我使用最低 SDK 15 和目标 23 构建了一个应用程序，并且在我的 RecyclerView 中有不同的 View 。应用程序在 android 版本 => 5.0 上运行良好，但在 android 版本 < 5.0 上崩溃并显示以下错误消息

如果你在ImageView中使用矢量图标作为背景并且android版本低于5.0，imageview会导致崩溃。尝试使用 <android.support.v7.widget.AppCompatImageView而不是 ImageView并且不要忘记在您的 Java 代码中也使用 appCompatImageView 声明和转换您的 imageview。要将矢量设置为背景，请使用此 xml 属性:app:srcCompat选择颜色使用 android:tint最后，在您的 gradle 文件中，您必须添加对向量的支持:

android {
    //...
    defaultConfig {
 //...

        vectorDrawables {
            useSupportLibrary = true
        }
    }
