本文介绍了如何褪色从白色到黑色?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧! 问题描述 29岁程序员,3月因学历无情被辞! 我有一个int数组来表示RGB值。我有一个定时器的颜色从白色到黑色,但我有一些问题。 。 我有一个定时器,每100ms运行一次,并递减数组中的RGB值。 我有,我将最终与中间的其他颜色,绿色黄色,红色等。 我想要做的是从白色解决方案声明一个全局变量和调用 fading 。 Color fading = Color.white; 在您的计时器正文中: if(fading.getRed()> 0){ fading = new Color(fading.getRed() - 1,fading.getGreen() - 1,fading.getBlue -1); //做任何与你的渐变颜色相关的操作} 每当您的计时器执行此代码,它会将RGB值从白色减少到黑色。 结果: LOOP NO | COLOR 1:R = 255,G = 255,B = 255 2:R = 254,G = 254,B = 254 3:R = 253,G = 253,B = 253 4:R = 252,G = 252,B = 252 5:R = 251,G = 251,B = 251 6:R = 250,G = B = 250 。 。 。 255:R = 0,G = 0,B = 0 示例: import java.awt。颜色; public Class YourClass { 颜色褪色= Color.white; public YourClass(){ TimerTask task = new TimerTask(){ @Override public void run(){ if(fading.getRed ()> 0){ fading = new Color(fading.getRed() - 1,fading.getGreen() - 1,fading.getBlue() - 1); //在这里做其他事情} } }; 定时器timer =新的Timer(); timer.scheduleAtFixedRate(task,0,100); } } I have a timer that's fading a color from white to black, but I'm having some issues.I have an array of ints to represent the RGB values.I have a timer which runs every 100ms and decrements the RGB value in the array.The problem I'm having is that I will end up with other colors in the middle, green yellow, red, etc.What I am trying to do is to fade from white to black, so I need the color to become a different shade of grey as the timer runs. 解决方案 Declare a global variable and call it fading.Color fading = Color.white;In your timer's body:if(fading.getRed()>0){ fading = new Color(fading.getRed()-1,fading.getGreen()-1,fading.getBlue()-1); //do whatever you have to do with your fading color}Everytime your timer executes this code it will decrease the RGB value from white to black.The result:LOOP NO | COLOR 1: R=255, G=255, B=255 2: R=254, G=254, B=254 3: R=253, G=253, B=253 4: R=252, G=252, B=252 5: R=251, G=251, B=251 6: R=250, G=250, B=250 . . . 255: R=0, G=0, B=0EDITExample:import java.awt.Color;public Class YourClass{ Color fading = Color.white; public YourClass(){ TimerTask task = new TimerTask() { @Override public void run() { if (fading.getRed() > 0) { fading = new Color(fading.getRed() - 1, fading.getGreen() - 1, fading.getBlue() - 1); //do other stuff here } } }; Timer timer = new Timer(); timer.scheduleAtFixedRate(task, 0, 100); }} 这篇关于如何褪色从白色到黑色?的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持! 上岸,阿里云! 09-02 05:35
