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( "http://www.google.com");   
Intent it  = new  Intent(Intent.ACTION_VIEW,uri);  
startActivity(it);  
Java代码 
Uri uri = Uri.parse("http://www.google.com");  
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);   
Java代码 
Uri uri = Uri.parse("geo:38.899533,-77.036476");  
Intent it = new Intent(Intent.Action_VIEW,uri);  
startActivity(it);

路径规划:

Uri uri = Uri.parse( "http://maps.google.com/maps?f=d&saddr=startLat%20startLng&daddr=endLat%20endLng&hl=en");   
  
Intent it = new  Intent(Intent.ACTION_VIEW,URI);  
  
startActivity(it);  
Java代码 
Uri  
uri = Uri.parse("http://maps.google.com/maps?f=d&saddr=startLat%20startLng&daddr=endLat%20endLng&hl=en");  
Intent  
it = new Intent(Intent.ACTION_VIEW,URI);  
startActivity(it);

拨打电话:
调用拨号程序

Uri uri = Uri.parse( "tel:xxxxxx" );  
  
Intent it = new  Intent(Intent.ACTION_DIAL, uri);    
  
startActivity(it);   
Java代码 
Uri uri = Uri.parse("tel:xxxxxx");  
Intent it = new Intent(Intent.ACTION_DIAL, uri);    
startActivity(it);   



Uri uri = Uri.parse( "tel.xxxxxx" );  
  
Intent it =new  Intent(Intent.ACTION_CALL,uri);  
  
要使用这个必须在配置文件中加入  
Java代码 
Uri uri = Uri.parse("tel.xxxxxx");  
Intent it =new Intent(Intent.ACTION_CALL,uri);  
要使用这个必须在配置文件中加入
