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:

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

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);

路径规划:

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

拨打电话:
调用拨号程序

1. Uri uri = Uri.parse("tel:xxxxxx");
2. Intent it = new Intent(Intent.ACTION_DIAL, uri);
3. startActivity(it);

1. Uri uri = Uri.parse("tel.xxxxxx");

12. //page, and notice the ID from the address bar
