(Source code introduction
Now the graphic unlocking on the mobile phone is very common. When I see this, is there an impulse to read the code? I have code. Do you want to try it? I downloaded one from the Internet. The amount of code is too large. Oh, I can't stand it. It's too exciting, isn't it! Then I deducted a small piece of code from another place. There is only one class that can be called directly without any modification. When I got it, the comments were a pile of random code, and my conversion was useless, so I deleted it. I installed a plug-in for eclipse that didn't work. It doesn't solve this problem, so if you can understand it, digest it. Use it if you don't understand!)
