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
