Android Intent的几种用法全面总结

Intent, 用法
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:
  1. Uri uri = Uri.parse("http://www.google.com");
  2. Intent it= new Intent(Intent.ACTION_VIEW,uri);
  3. startActivity(it);
复制代码 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);
复制代码 路径规划:
  1. Uri uri = Uri.parse("http://maps.google.com/maps?f=d&saddr=startLat%20startLng&daddr=endLat%20endLng&hl=en");

  3. startActivity(it);
