Question

我在Android应用中使用以下代码：

InsetDrawable id = new InsetDrawable(context.getDrawable(drawableId), 150, 200, 150, 400);
imageView.setImageDrawable(id);

它在较新的Android API级别上可以正常工作，但是在API 21（我要支持的最低级别）上会发生这种情况，并且应用程序崩溃：

似乎是Android支持库中的错误或此特定API级别中的错误，如此处所述：IllegalArgumentException: width and height must be > 0 in activity

是否有InsetDrawable的替代方法或API 21的某些解决方法？

InsetDrawable无法在API 21上运行-为什么？
