android天气预报开发
A. android天气预报控件省份和城市怎么实例化
使用Intent加载天气预报数据的服务，代码如下：
intent=newIntent(LoadUI.this,LoadDataService.class);
Bundlebundle=newBundle();//创建天气内容
bundle.putString("city",WeatherUtil.getDefaultCity(LoadUI.this));
bundle.putBoolean("check",false);//不编写内容
intent.putExtras(bundle);//封装天气
LoadUI.this.startService(LoadUI.this.intent);
LoadDataService类是用于加载天气预报数据的服务类，这个类需要做以下几件事情：
city=URLEncoder.encode(city,"UTF-8");
B. Android上的天气预报软件哪个准一点呀 谢谢
单以预报准确而言，个人最为推荐墨迹天气。一直在用，感觉很好。
1.墨迹天气
墨迹天气是一款以预报准确，覆盖城市广，流量少，界面华丽等为特点的桌面天气软件。
（支持语音播报天气，皮肤资源也非常丰富！）
另外还有几款好的软件，各有所长吧。
2.GO天气
GO天气是一款华丽炫酷的实时天气预报软件，可查看全球主要城市的天气。通过访问美国及全世界数万个地区中的最大的专业天气网，GO天气在任何时间任何地点，都可以获得最精确的天气信息。（Go团队出品，支持高清天气视频，十分华丽！）
3.MIUI天气
一款MIUI开发的天气软件，界面时尚大方美观，功能强大，支持全国城市，支持周边城市天气预报，支持天气提醒，支持污染指数等功能。
(提取自MIUI固件，高清皮肤，天气效果动态显示，给你最华丽的体验！)
4.天气通
天气通是一款免费手机天气预报软件。通过网络获取天气信息，以直观的图文方式显示，详尽的城市目录，支持多个预报网站。桌面图标典雅，天气网标则充满新意。
（功能全面，支持全屏动画，还有独特的日历备注功能！）
5.华丽动态天气
Animated Weather是Android手机上的天气预报应用程序，每日动态天气预报，逼真的动态天气特效，自定义背景，支持世界超过50000个城市的天气预报。
（可自定义背景，支持城市全面！）
希望对你有帮助。
C. 我用android做了个简单的天气预报，但是他只能用城市名的拼音进行搜索，怎样改为汉字搜索比如输
调用的是第三方API还是网页抓取的？
其实简单的可以switch选择……不过太繁琐了点。或者自己建立一个SQLite，从EditText获取后直接查找下数据库就ok了，而且也可以做到模糊搜索。
D. 用android开发天气预报左右滑动切换可以获取到城市信息怎么实现
看你用的API了,一般都是在网上找到城市代码的表格,然后选择城市对应的代码提交上去。
E. android端免费获取天气信息的服务器接口有么
中国国家气象局提供了获取所在城市天气预报信息接口。通过这个接口，我们就可以获取天气信息了。
关于获取天气预报的实例参考android学习手册，里面有源码。android学习手册包含9个章节，108个例子，源码文档随便看，例子都是可交互，可运行，源码采用android studio目录结构，高亮显示代码，文档都采用文档结构图显示，可以快速定位。360手机助手中下载,图标上有贝壳
中国国家气象局天气预报接口总共提供了三个：
http://www.weather.com.cn/data/sk/101010100.html
http://www.weather.com.cn/data/cityinfo/101010100.html
http://m.weather.com.cn/data/101010100.html
注：上面接口2014.3.4日已不再更新。换成这个：http://m.weather.com.cn/atad/101230201.html。各位看34楼。在此感谢tdwll和黄晓佳cobish。
最详细的信息来自第三个接口。上面url中的101010100是城市代码，这里是北京的城市代码。只需要改变城市代码，就可以得到所在城市的天气信息。笔者在福州，所以选择的城市代码是福州101230101。
在浏览器上输入url：http://m.weather.com.cn/data/101230101.html得到信息，天气信息是json的数据格式，数据如下：
{"weatherinfo":{"city":"福州","city_en":"fuzhou","date_y":"2012年5月14日","date":"","week":"星期一","fchh":"08","cityid":"101230101","temp1":"29℃~23℃","temp2":"26℃~20℃","temp3":"24℃~20℃","temp4":"25℃~20℃","temp5":"24℃~21℃","temp6":"25℃~22℃","tempF1":"84.2℉~73.4℉","tempF2":"78.8℉~68℉","tempF3":"75.2℉~68℉","tempF4":"77℉~68℉","tempF5":"75.2℉~69.8℉","tempF6":"77℉~71.6℉","weather1":"阵雨转中雨","weather2":"中雨转小雨","weather3":"小雨","weather4":"小雨","weather5":"小雨转阵雨","weather6":"阵雨转小雨","img1":"3","img2":"8","img3":"8","img4":"7","img5":"7","img6":"99","img7":"7","img8":"99","img9":"7","img10":"3","img11":"3","img12":"7","img_single":"3","img_title1":"阵雨","img_title2":"中雨","img_title3":"中雨","img_title4":"小雨","img_title5":"小雨","img_title6":"小雨","img_title7":"小雨","img_title8":"小雨","img_title9":"小雨","img_title10":"阵雨","img_title11":"阵雨","img_title12":"小雨","img_title_single":"阵雨","wind1":"微风","wind2":"微风","wind3":"微风","wind4":"微风","wind5":"微风","wind6":"微风","fx1":"微风","fx2":"微风","fl1":"小于3级","fl2":"小于3级","fl3":"小于3级","fl4":"小于3级","fl5":"小于3级","fl6":"小于3级","index":"热","index_d":"天气较热，建议着短裙、短裤、短套装、T恤等夏季服装。年老体弱者宜着长袖衬衫和单裤。","index48":"暖","index48_d":"较凉爽，建议着长袖衬衫加单裤等春秋过渡装。年老体弱者宜着针织长袖衬衫、马甲和长裤。","index_uv":"弱","index48_uv":"最弱","index_xc":"不宜","index_tr":"适宜","index_co":"较不舒适","st1":"27","st2":"21","st3":"24","st4":"18","st5":"22","st6":"18","index_cl":"较不宜","index_ls":"不太适宜","index_ag":"不易发"}}
我们可以解析json数据去得到自己想用的天气信息。

F. 编一个android的简单天气预报程序大概要用到哪些类都是干什么的可以简单说一下么
我可能会用到这几个类：
天气数据定义，比如晴天阴天，风向，风力，湿度，温度等。
网络请求和数据解析，因为功能比较简单，所以可以考虑放在一个类里。
界面类，简单的就只有一个activity好了，对应一些简单的功能，刷新天气之类的。
G. android 如何实现获取天气预报信息
方法步骤（以安卓5.0为例）
一、打开GPS
九、提示
1.适时刷新天气需要开启GPS定位。
2.在没有WIFI的地方刷新天气需要消耗一定的流量，刷新频率越高，消耗流量越多。
