最近要做一个网站，要求实现验证码进程，经过不断调试，终于成功实现功能。 一：验证码生成类 生成验证码的话需要用到java的Graphics类库，画出一个验证码 废话不多说，直接上代码 123456789101112131415161718192021222324252627282930313233343536373839404142434445464748495051525354555657585960616263646566676869707172737475767778798081828384858687888990919293949596979899100101102103104105106107108109110111112113114115116117118119120 package verificationCode;import java.awt.Color;import java.awt.Font;import java.awt.Graphics;import java.awt.image.BufferedImage;import java.awt.image.RenderedImage;import java.io.File;import java.io.FileNotFoundException;import java.io.FileOutputStream

I need a sample tutorial for the android SurfaceView , or sample code using it that can be shared. The API demos are difficult for me to understand. Does anyone have alternatives? This commit of my WorldMap demo app shows you the changes necessary to convert from an android.view.View to an android.view.SurfaceView with an android.view.SurfaceHolder.Callback . It cheats a bit by using the View 's onDraw() from within the SurfaceView 's DrawThread and by calling the View 's onSizeChanged() from within the SurfaceView 's surfaceChanged . It just makes the diff smaller and easier to understand. I

Hey all, is there a functioning demo out there for displaying multiple directions routes on a single Google map? The other question on stack links to a set of snippets…I feel like I'd be able to work better I just saw a functional script in action. Thanks much! Using the snippets from the other post, I got what I wanted. Not only did I achieve multiple directions displays on the same map, but there are also unique waypoints to each directions object.
