android - 如何保持 Button 的 BackgroundDrawable 的纵横比

Question

当我使用 Button.setBackgroundDrawable(drawable) 时，drawable 对象被拉伸而不是保持其纵横比。如何保持纵横比？我不能使用 ImageButton 因为我还需要在按钮上写文本的能力。FWIW，图像是从文件加载的 BitmapDrawable。

编辑：我想调整按钮的大小以适合图像。

Answer 1

What type of background will the buttons have? Is it an image of something? Or just a custom border and color scheme and what not?

If it is just a custom button look, I would look into using 9-patch drawables. They will allow you to make buttons of all different shapes and sizes and have the corners of your buttons maintain the proper sizing.
