Intent应该算是Android中特有的东西。你可以在Intent中指定程序要执行的动作（比如：view,edit,dial），以及程序执行到 该动作时所需要的资料。都指定好后，只要调用startActivity()，Android系统会自动寻找最符合你指定要求的应用程序，并执行该程序。

下面列出几种Intent的用法
显示网页: Uri uri = Uri.parse( "<a href=" http: //www.Google.com" target="_blank" rel="external">http://www.google.com</a>");   

Intent it  = new  Intent(Intent.ACTION_VIEW,uri);  

startActivity(it);  
复制代码
java代码
Uri uri = Uri.parse("<a href="http://www.google.com" target="_blank" rel="external">http://www.google.com</a>");

Intent it  = new Intent(Intent.ACTION_VIEW,uri);

startActivity(it);

显示地图:
Uri uri = Uri.parse( "geo:38.899533,-77.036476" );  

Intent it = new  Intent(Intent.Action_VIEW,uri);  

startActivity(it);   
复制代码路径规划: Uri uri = Uri.parse( "<a href=" http: //maps.google.com/maps?f=d" target="_blank" rel="external">http://maps.google.com/maps?f=d</a>&saddr=startLat%20startLng&daddr=endLat%20endLng&hl=en");   

  

Intent it = new  Intent(Intent.ACTION_VIEW,URI);  

  

startActivity(it);
复制代码Java代码 Uri

uri = Uri.parse("<a href="http://maps.google.com/maps?f=d"

target="_blank"

复制代码拨打电话:
调用拨号程序
Uri uri = Uri.parse( "tel:xxxxxx" );

要使用这个必须在配置文件中加入<uses-permission id="android.permission.CALL_PHONE"  />
