如何在我的应用程序中使用colorpicker？(how to use colorpicker with my application?)

我已经制作了一个简单的Android绘图应用程序，因为我已经为不同的颜色采取了不同的按钮，现在我想要的是，当我点击红色按钮时，我的笔颜色应该被转换为red.same作为不同的颜色..我的代码是如下，请建议我的朋友..

最满意答案

如果我理解你的问题，你可以扩展FrameLayout并添加Button / ImageView，铅笔绘制透明。

有了这个你只需要改变FrameLayout背景，并可以使用相同的视图制作任何颜色按钮。

If i understand your question you can extend FrameLayout and add to it the Button/ImageView with the pencil draw transparent.

With this you only should to change the FrameLayout background and can make whatever color button with the same View.
