开一家网站建设公司怎样,绍兴网站制作软件,广州开发区投资集团,家用电脑可以做网站服务器效果图全部正确#xff1a;有对有错#xff1a;结果展示#xff0c;纯黑色#xff1a;支持图片#xff1a;实现思路仔细分析可以发现#xff0c;连线题的布局可以分为两部分#xff0c;一个是左右两列矩形#xff0c;另一个是他们之间的连线。每个矩形的宽高都一样有对有错结果展示纯黑色支持图片实现思路仔细分析可以发现连线题的布局可以分为两部分一个是左右两列矩形另一个是他们之间的连线。每个矩形的宽高都一样或者等比例这样利于给他们定位添加矩形时使用ViewGroup#ddView(View child, LayoutParams params)方法我们通过LayoutParams参数来控制每个矩形的位置。为了方便添加矩形这里我们的自定义布局继承自RelativeLayout。public class LinkLineView extends RelativeLayout {...
}接下来说连线连线我们通过记录他们的起点和终点数据然后调用View#invalidate方法在ViewGgroup#dispatchDraw()方法里面通过canvas.drawLine()方法进行绘制。我们假设线都是从左向右连的起点就是左边矩形右边距的中点终点就是右边矩形左边距的中点。在添加矩形的时候我们可以知道每个矩形的具体参数所以所有连线的起点和终点的数据我们是知道的接着就是如何表示一根线的问题。在所有连线完成之前连线是可以取消掉的在所有连线完成后我们需要用连线结果跟正确结果进行比对的所以我们需要针对每次连线定义一个数据结构具体如下public class LinkLineBean {/*** 直线的横纵坐标*/private float startX;private float startY;private float endX;private float endY;public LinkLineBean(float startX, float startY, float endX, float endY) {this.startX startX;this.startY startY;this.endX endX;this.endY endY;}// 省略getter和setter方法Overridepublic boolean equals(Object o) {if (this o) {return true;}if (!(o instanceof LinkLineBean)) {return false;}LinkLineBean that (LinkLineBean) o;return (Float.compare(that.startX, startX) 0 Float.compare(that.startY, startY) 0 Float.compare(that.endX, endX) 0 Float.compare(that.endY, endY) 0)|| (Float.compare(that.startX, endX) 0 Float.compare(that.startY, endY) 0 Float.compare(that.endX, startX) 0 Float.compare(that.endY, startY) 0);}Overridepublic int hashCode() {return Objects.hash(startX, startY, endX, endY);}
}这里省略了一些不必要的代码。重写equals和hashCode方法是为了比较是否是同一条连线。如果连线A的起点等于连线B的终点连线A的终点等于连线B的起点我们就认为他们是同一条连线这个也符合我们的常识同一条线从左向右连和从右向左连是一样的。核心思路说完了剩下的就是一些细节处理了。源码实现连线题父容器/*** Description: 连线题的父容器* Version*/
