说明：  android 8.0之前的悬浮窗口Demo代码(android before 8.0 float window Demo source code)

ImageView 类描述：显示任意图像，例如图标。ImageView可以加载任意来源的图片（如资源或图片库），需要计算图片的尺寸，以便它可以在其他布局中使用，并提供例如缩放和着色（渲染）各种显示选项

    首先是布局文件,布局中需要一个HorizontalScrollView用来承载所有标题和指示器,注意HorizontalScrollView中只能有一个子布局,所以要添加一个Linearlayout(竖向的),这里为什么是竖向的呢?因为这个线性布局中要加入一个横向的线性布局用来动态增加所有标题内容,和一个标题下面的指示器.
