天气预报源代码

先上效果图

​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​

在这里更正一下，黑天的天气预报界面截图的时候，当时操作系统的时间是错误的，导致模拟器里显示2008年。

天气预报是我学WindowsPhone7以来的第一个作品。用的是谷歌的api。功能一个下午就写完了，还是这个界面的设计加P图费了我不少的时间。这个应用已经通过了微软的审核。

由于界面过于复杂，为了实现高效的重用性，我使用了用户自定义控件。通过后台对象的实例化生成的界面。没有办法把所有的代码都展现出来。

1:  // 应用程序启动(例如，从“开始”菜单启动)时执行的代码

2:          // 此代码在重新激活应用程序时不执行

3:          private void Application_Launching(object sender, LaunchingEventArgs e)

4:          {

5:              if (!IsolatedStorageSettings.ApplicationSettings.Contains("City"))

6:              {

7:                  List<CityWeatherInfo> citys = new List<CityWeatherInfo>();

8:                  IsolatedStorageSettings.ApplicationSettings["City"] = citys;

9:                  IsolatedStorageSettings.ApplicationSettings.Save();

10:              }

11:          }

1:  List<CityWeatherInfo> citys = new List<CityWeatherInfo>();

我使用的是IsolatedStorageSettings.ApplicationSettings存储的城市信息。下面为添加城市信息的代码。

1:  //添加城市

2:          private void AddCityButton_Click(object sender, RoutedEventArgs e)

3:          {

4:

5:              if ((citys.Where(list => list.CityName == CityNameTextBox.Text).ToList()).Count == 0)

6:              {

7:                  citys.Add(new CityWeatherInfo() { CityGuid = Guid.NewGuid().ToString(), CityName = CityNameTextBox.Text });

8:                  IsolatedStorageSettings.ApplicationSettings["City"] = citys;

9:                  IsolatedStorageSettings.ApplicationSettings.Save();

10:              }

11:              IsolatedStorageSettings.ApplicationSettings["City"] = citys;

12:              IsolatedStorageSettings.ApplicationSettings.Save();

13:              NavigationService.Navigate(new Uri("/Loading.xaml?cityName=" + CityNameTextBox.Text+"&AndGoPage=MainPage", UriKind.RelativeOrAbsolute));

14:          }

 

1:  //删除城市

2:          private void linkButtonDel_Click(object sender, RoutedEventArgs e)

3:          {

4:              for (int i = 0; i < citys.Count; i++)

5:              {

6:                  if (citys[i].CityGuid == ((HyperlinkButton)sender).Tag.ToString())

7:                  {

8:                      citys.RemoveAt(i);

9:                  }

10:              }

11:              IsolatedStorageSettings.ApplicationSettings["City"] = citys;

12:              IsolatedStorageSettings.ApplicationSettings.Save();

13:              BindData();

14:          }

先上获取天气信息的代码，我自己写了个获取谷歌天气信息的工具类，生成了DLL然后引用进来使用的。
