布局省略
测试代码入下：
HighLightGuideView.builder(this) .addHighLightGuidView(confirm, R.mipmap.unchain) .setHighLightStyle(HighLightGuideView.VIEWSTYLE_RECT) .show(); HighLightGuideView.builder(this) .addHighLightGuidView(confirm, R.mipmap.unchain) .setHighLightStyle(HighLightGuideView.VIEWSTYLE_CIRCLE) .show();// HighLightGuideView.builder(this) .addHighLightGuidView(confirm, R.mipmap.unchain) .setHighLightStyle(HighLightGuideView.VIEWSTYLE_OVAL) .show(); HighLightGuideView.builder(this) .addHighLightGuidView(setting_feedback_text, R.mipmap.input_pass) .setHighLightStyle(HighLightGuideView.VIEWSTYLE_NO) .show();参数的意思是：
addHighLightGuidView为哪个控件设置高亮，以及在该控件处填指示的图片
setHighLightStyle设置高亮的类型–矩形、圆形、椭圆、以及没有高亮
HighLightGuideView
