如何在图像位图上绘制标记？

Question

I need help to do the following task. My task is similar to Pose (an Android application). In this application they done a amazing concept. Once you capture the image, then tap any part of the image it shows number of options to add tagline. Once you add the tag means the particular tag is added over the image. once you upload the image to server, now you can view in your profile, once you touch on the image, the tag parts are visible, then you again touch the image means the tagged icons are disappeared. How they do this think, if they are using any third party tool?.Here for your reference i added the market link of Pose application also having a video and Sample images and i also added some images kindly notice it. Kindly share you valuable suggestion to completed this task.

您可以使用FrameLayout并尝试将标记放在图像上，但是我可能会创建一个自定义View ，覆盖onDraw方法并为所有这些做自定义绘图。
