我有一个imageview，我设置图像以填充不同的颜色。但是当我填充颜色时，其他颜色不会填充在imageview上相同的区域，而前一种颜色被填充。我使用颜色托盘按钮获取不同颜色以填充imageview。以下是我的代码和图片说明。

如果您希望图像中的多个图层在每个图层上具有不同的颜色，则可以使用A LayerDrawable。 LayerDrawable允许您创建具有不同图层的Drawable对象。您可以根据需要定位图层。
示例：
Drawable largeIcon = getResources().getDrawable(R.drawable.app_icon);
ShapeDrawable bg = new ShapeDrawable();
bg.getPaint().setColor(Color.RED);
Drawable[] layers = {bg, largeIcon};
LayerDrawable layerDrawable = new LayerDrawable(layers);
layerDrawable.setLayerInset(0, 0, 0, 0, 0);
layerDrawable.setLayerInset(1, 35, 35, 35, 35); // relative positioning of next layer
return layerDrawable

在ACTION_UP上你做了一件奇怪的事，这是你的代码：
path.lineTo(eventX, eventY);
canvas.drawPath(path, paint);
paths.add(path);
path.reset();
最后路径很清楚。下次到达那里，你添加一个lineTo，并绘制它，这将是一个空路径。您添加路径的路径，并清除路径。这是我看到的唯一一个画布绘图代码，所以我甚至不知道你的问题在哪里
答案 2 :(得分：1)
您遇到的问题是使用PorterDuff.Mode绘制所有路径。你真正想做的是在没有任何PorterDuff.Mode的情况下绘制所有路径，然后进行最终渲染并将其应用于具有PorterDuff.Mode的A形状。如果有更多的时间，我应该能够为你写一个例子。您的代码还有许多其他问题。
