WP7 Launcher 啓動器

在WindowsPhone中需要調用系統資源的話需要用到啓動器（Launcher）和選擇器（Choosers）。

其實已經很多人寫過了，最近正好用到，再總結下吧…

先寫啓動器（Launcher），等下週有時間再寫選擇器（Choosers）。

1，Launchers

 

 

目前WindowsPhone啓動器一共有15個

其中7.0支持的有10個：

EmailComposeTask

MarketplaceDetailTask

MarketplaceHubTask

MarketplaceReviewTask

MarketplaceSearchTask

MediaPlayerLauncher

PhoneCallTask

SearchTask

SmsComposeTask

WebBrowserTask

 

7.1新增了5個：

BingMapsDirectionsTask

BingMapsTask

ConnectionSettingsTask

ShareLinkTask

ShareStatusTask

 

2，BingMapsDirectionsTask

BingMapsDirectionsTask的功能是一個基於bing地圖的路徑導航，屬性有兩個（起點和終點），值類型爲LabeledMapLocation

	Name	Description
	End	The ending location for which driving directions are displayed.
	Start	The starting location for which driving directions are displayed.

用法也很簡單：

BingMapsDirectionsTask bingMapsDirectionsTask = new BingMapsDirectionsTask();            
GeoCoordinate spaceNeedleLocation = new GeoCoordinate(0,0);
LabeledMapLocation spaceNeedleLML1 = new LabeledMapLocation("Somewhere", spaceNeedleLocation);
LabeledMapLocation spaceNeedleLML2 = new LabeledMapLocation("qingdao", null);
bingMapsDirectionsTask.End = spaceNeedleLML2;
bingMapsDirectionsTask.Start = spaceNeedleLML1;
bingMapsDirectionsTask.Show();

其中LabeledMapLocation的第二個參數爲地理座標，如果爲NULL的話，bing地圖會根據第一個參數的字符串進行搜索

另外如果不設置bingMapsDirectionsTask.Start的話，默認以當前GPS定位爲出發地址。

效果：

最後，bing map在米國貌似不錯，天朝比較坑爹…路徑導航基本沒戲….

還有手機區域語言選中國，基本不工作，選英國、米國都正常…

 

 

3，BingMapsTask

BingMapsTask的功能就是一個比較簡單的bing地圖調用，你可以設置地圖的中間點、縮放級別或者領用bing地圖搜索。

	Name	Description
	Center	Gets or sets the location that will be used as the center point for the map.
	SearchTerm	Gets or sets the search term that is used to find and tag locations on the map.
	ZoomLevel	Gets or sets the initial zoom level of the map.

BingMapsTask bingMapsTask = new BingMapsTask();
bingMapsTask.Center = new GeoCoordinate(47.6204,-122.3493);
//bingMapsTask.SearchTerm = "qingdao";
bingMapsTask.ZoomLevel = 50;
bingMapsTask.Show();

其中ZoomLevel是double型，而且必須大於0 

效果：

 

 

4，ConnectionSettingsTask

ConnectionSettingsTask功能是快速導航到WP的網絡設置（包括WIFI、數據連接、藍牙和飛行模式）

Name	Description
	ConnectionSettingsType	Gets or sets the type of network connection settings that will be displayed.

ConnectionSettingsTask connectionSettingsTask = new ConnectionSettingsTask();
connectionSettingsTask.ConnectionSettingsType = ConnectionSettingsType.WiFi;
//connectionSettingsTask.ConnectionSettingsType = ConnectionSettingsType.AirplaneMode;
//connectionSettingsTask.ConnectionSettingsType = ConnectionSettingsType.Bluetooth;
//connectionSettingsTask.ConnectionSettingsType = ConnectionSettingsType.Cellular;
connectionSettingsTask.Show();

效果就不加了，相當於快捷方式而已

 

 

5，EmailComposeTask

EmailComposeTask功能是調用綁定的郵箱發送郵件。

	Name	Description

emailComposeTask.Show();

標題、正文、收件人、抄送、密送，不多說了..

效果：

//marketplaceDetailTask.ContentType = MarketplaceContentType.Applications;
marketplaceDetailTask.Show();

ContentType默認爲MarketplaceContentType.Applications，不用設置就可以
