README.md

  • GuideView

  • 本系统能够快速的为一个Activity里的任何一个View控件创建一个遮罩式的导航页。

  • 工作原理

  • 首先它需要一个目标View或者它的id,我们通过findViewById来得到这个View,计算它在屏幕上的区域targetRect,通过这个区域,开始绘制一个覆盖整个Activity的遮罩,可以定义遮罩的颜色和透明度,然而目标View被绘制成透明从而实现高亮的效果。接下来是在相对于这个targetRect的区域绘制一些图片或者文字。我们把这样一张图片或者文字抽象成一个Component接口,设置文字或者图片,所有的图片文字都是相对于targetRect来定义的。可以设定额外的x,y偏移量,可以对遮罩系统设置可见状态的发生变化时的监听回调,可以对遮罩系统设置开始和结束时的动画效,另外,我们可以不对整个Activity覆盖遮罩,而是对某一个View覆盖遮罩。

  • 注意:具体用法参见demo,内附详细注释
