Android自定义View画笔颜色改变问题（画笔颜色改变了，但是实际上ABCD这些字母的颜色没变）

}

就是不变颜色啊，求大神告诉下问题

你的ondraw事件里
paint.setColor(color.custom_yellow);
都写死了啊

这颜色都没变吧

 if(i==choice-1){
    paint.setColor(color.custom_yellow);
    paint.setTextSize(32);
}else{
    paint.setColor(color.custom_yellow);
    paint.setTextSize(textSize);

}

同上，你就设置过一次颜色，都是
paint.setColor(color.custom_yellow);

肯定都一样啊

我现在代码实现的效果就是，默认黑色。然后手去滑动会变颜色和字体大小。 但是现在需要的是改变他的默认颜色。
把黑色改为黄色。我代码故意设死了黄色。但是他还是黑色
