问题描述

我有各种各样的按钮，我想获得它们的背景颜色，在彩色可绘制对象中获取背景颜色很容易，但在波纹可绘制对象中并不容易，我如何设法从波纹可绘制对象中获取背景颜色.

I have variety of buttons and I would like to get their background color, getting background color in a color drawable is easy but it is not easy in ripple drawable, how can I manage to get background color from ripple drawable.

推荐答案

尝试一下:

 RippleDrawable rippleDrawable = (RippleDrawable) button.getBackground();
 Drawable.ConstantState state = rippleDrawable.getConstantState();
 try {
     Field colorField = state.getClass().getDeclaredField("mColor");
     colorField.setAccessible(true);
     ColorStateList colorStateList = (ColorStateList) colorField.get(state);
     int rippleColor = colorStateList.getDefaultColor();
  } catch (NoSuchFieldException e) {
      e.printStackTrace();
  } catch (IllegalAccessException e) {
      e.printStackTrace();
  }
