• 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，并且可以再高亮区域绘制任何你想要的布局或者lottie动画等炫酷效果

• 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。

• 注意：具体用法参见demo，内附详细注释

• 

• 使用方法

• 1.添加gradle依赖

  implementation 'com.binioter:guideview:1.0.0'

• 2.编写用于在高亮区域周围展示的component

• public class SimpleComponent implements Component {
  
        @Override public View getView(LayoutInflater inflater) {
  
          LinearLayout ll = (LinearLayout) inflater.inflate(R.layout.layer_frends, null);
          ll.setOnClickListener(new View.OnClickListener() {
            @Override public void onClick(View view) {
              Toast.makeText(view.getContext(), "引导层被点击了", Toast.LENGTH_SHORT).show();
            }
          });
          return ll;
        }
  
        @Override public int getAnchor() {
          return Component.ANCHOR_BOTTOM;
        }
  
        @Override public int getFitPosition() {
          return Component.FIT_END;
        }
  
        @Override public int getXOffset() {
          return 0;
        }
  
        @Override public int getYOffset() {
          return 10;
    }
  }

• 3.展示引导蒙层，并监听蒙层展示、隐藏事件

•  public void showGuideView() {
      GuideBuilder builder = new GuideBuilder();
      builder.setTargetView(header_imgbtn)
              .setAlpha(150)
              .setHighTargetCorner(20)
              .setHighTargetPadding(10);
      builder.setOnVisibilityChangedListener(new GuideBuilder.OnVisibilityChangedListener() {
        @Override
        public void onShown() {
        }
  
        @Override
        public void onDismiss() {
          showGuideView2();
        }
      });
  
      builder.addComponent(new SimpleComponent());
      guide = builder.createGuide();
      guide.show(SimpleGuideViewActivity.this);
