Question

我有一个自定义视图，其中包含以下视图层次结构：

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

最后RecyclerView的每个项目都包含 3个矢量绘图。当我在KitKat（api 19）上运行应用程序时，StackOverflowError发生了

我在AppCompatDelegate.setCompatVectorFromResourcesEnabled(true); Application onCreate()和vectorDrawables.useSupportLibrary = true build.gradle中http://localhost:3000启用200的矢量绘图

当我使用普通的 PNG drawable时，错误不会发生。

我做错了什么？

Answer 1

在onBindViewHolder中以编程方式创建 vector-drawable 并将其设置为您的视图： -

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

现在将此drawable设置为onBindViewHolder ...

中的视图

  yourView.setBackground(your_vector_drawable);

这有望解决：）

这是一个较低的api问题......

Answer 2

我首先将矢量drawable转换为Bitmap，然后使用ImageView.setImageBitmap(Bitmap)将其提供给ImageView，从而解决了这个问题。这样做效率较低，但完成工作

由于矢量drawables，KitKat上的StackOverflowError
