WP7 Launcher 启动器

2012-04-11 23:42 260 查看


在WindowsPhone中需要调用系统资源的话需要用到启动器（Launcher）和选择器（Choosers）。


其实已经很多人写过了，最近正好用到，再总结下吧…

先写启动器（Launcher），等下周有时间再写选择器（Choosers）。


1，Launchers



目前WindowsPhone启动器一共有15个

其中7.0支持的有10个：

EmailComposeTask

MarketplaceDetailTask

MarketplaceHubTask

MarketplaceReviewTask

MarketplaceSearchTask

MediaPlayerLauncher

PhoneCallTask

SearchTask

SmsComposeTask

WebBrowserTask

7.1新增了5个：

BingMapsDirectionsTask

BingMapsTask

ConnectionSettingsTask

ShareLinkTask

ShareStatusTask


2，BingMapsDirectionsTask

BingMapsDirectionsTask的功能是一个基于bing地图的路径导航，属性有两个（起点和终点），值类型为LabeledMapLocation
NameDescription

EndTheendinglocationforwhichdrivingdirectionsaredisplayed.

StartThestartinglocationforwhichdrivingdirectionsaredisplayed.
用法也很简单：
BingMapsDirectionsTaskbingMapsDirectionsTask=newBingMapsDirectionsTask();
GeoCoordinatespaceNeedleLocation=newGeoCoordinate(0,0);
LabeledMapLocationspaceNeedleLML1=newLabeledMapLocation("Somewhere",spaceNeedleLocation);
LabeledMapLocationspaceNeedleLML2=newLabeledMapLocation("qingdao",null);
bingMapsDirectionsTask.End=spaceNeedleLML2;
bingMapsDirectionsTask.Start=spaceNeedleLML1;
bingMapsDirectionsTask.Show();


其中LabeledMapLocation的第二个参数为地理坐标，如果为NULL的话，bing地图会根据第一个参数的字符串进行搜索

另外如果不设置bingMapsDirectionsTask.Start的话，默认以当前GPS定位为出发地址。

效果：



最后，bingmap在米国貌似不错，天朝比较坑爹…路径导航基本没戏….

还有手机区域语言选中国，基本不工作，选英国、米国都正常…


3，BingMapsTask

BingMapsTask的功能就是一个比较简单的bing地图调用，你可以设置地图的中间点、缩放级别或者领用bing地图搜索。
NameDescription

CenterGetsorsetsthelocationthatwillbeusedasthecenterpointforthemap.

SearchTermGetsorsetsthesearchtermthatisusedtofindandtaglocationsonthemap.

ZoomLevelGetsorsetstheinitialzoomlevelofthemap.
BingMapsTaskbingMapsTask=newBingMapsTask();
bingMapsTask.Center=newGeoCoordinate(47.6204,-122.3493);
//bingMapsTask.SearchTerm="qingdao";
bingMapsTask.ZoomLevel=50;
bingMapsTask.Show();


其中ZoomLevel是double型，而且必须大于0

效果：




4，ConnectionSettingsTask

ConnectionSettingsTask功能是快速导航到WP的网络设置（包括WIFI、数据连接、蓝牙和飞行模式）

NameDescription

ConnectionSettingsTypeGetsorsetsthetypeofnetworkconnectionsettingsthatwillbedisplayed.
ConnectionSettingsTaskconnectionSettingsTask=newConnectionSettingsTask();
connectionSettingsTask.ConnectionSettingsType=ConnectionSettingsType.WiFi;
//connectionSettingsTask.ConnectionSettingsType=ConnectionSettingsType.AirplaneMode;
//connectionSettingsTask.ConnectionSettingsType=ConnectionSettingsType.Bluetooth;
//connectionSettingsTask.ConnectionSettingsType=ConnectionSettingsType.Cellular;
connectionSettingsTask.Show();


效果就不加了，相当于快捷方式而已

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

ContentType默认为MarketplaceContentType.Applications，不用设置就可以

//marketplaceHubTask.ContentType=MarketplaceContentType.Applications;

mediaPlayerLauncher.Controls=MediaPlaybackControls.Pause|MediaPlaybackControls.Stop;

NameDescription

效果：
