如何在Android中绘制弯曲的文本

Question

I'm trying to build a text editing app that allows the user to edit text using different fonts, colors, sizes, rotations, etc. I'm working on a feature that is supposed to curve the text but I've got no clue how to do it. I found this StackOverflow post HERE and searching through the comments, I found this post HERE but for what I'm trying to achieve, that is how I want it to end up. What I want it to do is start as a normal line of text and then based on the value of a seekbar I want it to curve, until it reaches the MAX value at which point it's in a circle (as seen in the second link). If you can help me figure out how to do this I would really appreciate it. I figure it's going to use path.addArc or something like that but I'm not sure.

Thank you

PS I'll post the images below just in case you don't want to go look at the links

您可以在自定义视图中绘制圆形文本，使用画布函数drawTextOnPath（String text，Path path，float hOffset，float vOffset，Paint paint），然后根据需要构造路径。
