创建后如何更改InsetDrawable Inset值 [英] How to Change InsetDrawable Inset value after creation

问题描述

我定义了InsetDrawable，我希望能够在运行时调整inset的值，而无需重新分配另一个drawable.

I have an InsetDrawable defined, and I would just like to be able to adjust the value of the inset at runtime, without re-assigning another drawable.

这可能吗?还是唯一的方法是重新创建InsetDrawable?

Is this possible?, or is the only way is to re-create the InsetDrawable?

推荐答案

这是不可能的，因为该API并不公开. 我遇到了与您相同的问题，但就我而言，我必须对插图进行动画处理，因此重新创建可绘制对象是一个非常昂贵的选择.

It is not possible, because the API for that is not public. I had the same problem as you did, but in my case I had to animate the insets, so recreating the drawable was a quite costly option.

最后，我复制了InsetDrawable的源代码，并添加了一种更改inset的方法.

In the end I copied the source code of InsetDrawable, and added a method for changing the inset.

您可以在此处进行查看.使用方法setInsets()更改插图.

You can check it out here. Use the method setInsets() for changing the insets.
