我正在开发应用程序的 Android 版本,并尝试复制此图片中显示的设计。 http://s1298.photobucket.com/user/Mitch_Thornton/media/Screenshot2013-06-03at50428PM_zps3d9b6acc.png.html?sort=3&o=0
我存储的数据是从网站输入的。到目前为止,我已经成功地做到了,所以自动完成功能可以正确地搜索数据。我的问题是格式。我希望能够控制和风格化文本的某些部分。具体百分比。如果百分比高于 75%,则应为绿色,如果低于,则应为红色或黄色。
问题是,我正在处理一根长绳,所以我不能单独设计某些作品。
通过添加空格和线条,我能够获得穷人的样式版本,但没什么特别的......这是我到目前为止所拥有的 http://s1298.photobucket.com/user/Mitch_Thornton/media/Screenshot2013- 06-03at51100PM_zps6859e634.png.html?sort=3&o=1
我是 Android 新手,所以到目前为止我所学到的都是从教程和一些自学中获得的。我真的很感激你的帮助
