在“设置”屏幕中选择的颜色必须按顺序显示，作为先前活动中的动画

Question

我正在使用一个“彩色屏幕”应用程序。主要活动显示初始颜色选择，以供用户显示。

[选择颜色后，“主”（Main）活动切换到“灯”（Lamp）活动，该活动以全屏显示选定的颜色-“此零件为精细”。

当用户点击“灯泡活动”屏幕时，将调用“设置”活动。在这里，我正在研究应用程序的“序列”设置，通过该按钮，用户可以使用切换按钮在“序列”活动中以动画序列显示的颜色来选择颜色序列。

在主屏幕上，我还具有一个名为“彩虹”的按钮，该按钮可在预设颜色之间进行动画处理-可以正常工作，并且与我要执行的操作类似，但可以由用户编辑并可以将其保存为“预设” 。“

由于这似乎涉及许多程序，所以我对如何实现这一点感到迷惑-非常感谢您的帮助：

Answer 1

不确定我是否完全理解您的问题，但是也许您应该将所有有关颜色序列的详细信息保存为Class对象？

我的意思是，创建一个与此类似的类：

class ColorSequence{
    private startColor startColor;
    private endColor endColor;

    public createSequence(startColor startColor, endColor endColor){
        this.startColor = startColor;
        this.endColor = endColor;
}
// add more properties and functions as you need...

这里，您可以保存所有需要的数据，并在创建新的活动实例时在布局/活动之间传递此ColorSequcene对象。
