请教java高手们,帮我写一个java编写的图片浏览器,
功能如下:
有自动浏览功能,每隔几秒图片自动翻页;
用背景音乐的设置;
有开始、停止、下一页,上一页等功能。
谢谢了!
//改编的,CopyOfImageViewer.java 打开一个有图片的文件夹就可浏览了。
//MP3播放相关库到:http://www.javazoom.net/javalayer/sources.html 下载
//将下载到的zip文件里的 jl1.0.1.jar 复制到 JDK目录下的 jre/lib/ext/ 目录里即可.
//将 源代码 main 方法里的 playMp3("d:\\\\bad.mp3");改成自己的地址,换种方法BMP是可以支持的,这里不行暂不讨论。

参考技术A 我搞出来了!效果绝对让你满意!呵呵……(但有一点缺陷:没有背景音乐,因为我暂时还没有弄过有音乐的东西)。
准备工作如下(最好你直接HI我,我把整个项目的代码给你):
在根目录(src)下放置1.jpg 2.jpg 3.jpg图片。
代码如下:

(0079007的答案我也想运行一下看看效果,但代码是有错误的……不能正确编译) 参考技术B
bmp有难度,其它参考楼上的,自己玩去吧
参考技术C 废物东西.. 参考技术D zhanzuo !请教Java myBatis高手一个“#”、“$”、“'”、“%”包裹字符串时的整体字符串整体的含义。
高手,小弟的遇到的场景如下图: 希望高手能够点拨四个问题: 1.“#”包裹的字符串整体,表示什么含义? 2.“$”包裹的字符串整体,表示什么含义? 3.“'”包裹的字符串整体,表示什么含义? 4.“%”包裹的字符串整体,表示什么含义?
参考技术A#将传入的数据都当成一个字符串,会对自动传入的数据加一个双引号。如:order by #user_id#,如果传入的值是111,那么解析成sql时的值为order by "111", 如果传入的值是id,则解析成的sql为order by "id".
$将传入的数据直接显示生成在sql中。如:order by $user_id$,如果传入的值是111,那么解析成sql时的值为order by user_id, 如果传入的值是id,则解析成的sql为order by id.
'包裹的字符串将直接当着值
%包裹字符串表是模糊匹配
$和#差不多,只是原样展示,不加'单引号
' 看你的图应该是sql语句的东西,就是个单引号,这是sql的基础
%是sql的东西,表示N多字符。本回答被提问者采纳
以上是关于请教java高手们,帮我写一个java编写的图片浏览器,功能如下:有自动浏览功能,每隔几秒图片自动翻页。用的主要内容,如果未能解决你的问题,请参考以下文章
帮我做一下题,JAVA的,但是我要原因,错的题就麻烦高手给我写的详细点吧!谢谢啊!
请教Java SE高手一个简单的“@SuppressWarnings("unlikely-arg-type")”注释的含义是啥?
