Android Intent的几种用法全面总结

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);
显示地图:

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);

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);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<uses-permission id="android.permission.CALL_PHONE" /
