我有一个具有以下视图层次结构的自定义视图:

[LinearLayout]
  [CardView]
    [LinearLayout]
      [RecyclerView]

最后的每个项目 RecyclerView 包含 3矢量牵引 。当我在KitKat(api 19)上运行应用程序时 StackOverflowError 发生

我正在使用 AppCompatDelegate.setCompatVectorFromResourcesEnabled(true); 在 Application 类别的 onCreate() 和 vectorDrawables.useSupportLibrary = true 在里面 build.gradle

当我使用普通 巴布亚新几内亚 drawables错误不会发生。

我做错了什么?

在里面 onBindViewHolder 创建您的 矢量可绘制 以编程方式将其设置为您的视图,如下所示:-

   Drawable your_vector_drawable = VectorDrawableCompat.create(context.getResources(), R.drawable.vectorDrawable, null);

现在将此可绘制视图设置为 onBindViewHolder 。。。

  yourView.setBackground(your_vector_drawable);

这将有望解决:)

这是一个较低的api问题。。。

我通过将向量drawable转换为 Bitmap 首先,然后使用 ImageView.setImageBitmap(Bitmap) 。虽然性能较差,但可以完成工作
