Android - paint.setShadowLayer忽略shadowColor

Question

我面临着阴影颜色的问题，setShadowLayer方法忽略了shadowColor（这里我在我的代码中指定了Color.RED）而不是setShadowLayer正在采用颜色（这里是Color.argb（255,50,153,187））。下面是我的绘画设置并找到附件图片以供参考，感谢

    paint.setAntiAlias(true);
    paint.setColor(Color.argb(255, 50, 153, 187));
    paint.setStyle(Paint.Style.STROKE);
    paint.setStrokeJoin(Paint.Join.ROUND);
    paint.setStrokeWidth(STROKE_WIDTH);
    paint.setStrokeCap(Paint.Cap.ROUND);
    paint.setShadowLayer(7.0f, 20.0f, 2.0f, Color.RED);

Answer 1

shadowLayer仅在禁用硬件加速时起作用。添加

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB) { 
      setLayerType(LAYER_TYPE_SOFTWARE, paint); 
}

它应该有效
