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
1.显示网页:

1. Uri uri = Uri.parse("http://www.google.com");
   
2. Intent it  = newIntent(Intent.ACTION_VIEW,uri);
   
3. startActivity(it);

2.显示地图:

1. Uri uri = Uri.parse("geo:38.899533,-77.036476");
   
2. Intent it = new Intent(Intent.Action_VIEW,uri);
   
3. startActivity(it);

3.路径规划:

1. Uri uri =Uri.parse("http://maps.google.com/maps?f=d&saddr=startLatstartLng&daddr=endLat endLng&hl=en");
