Intent中指定程序要执行的动作

eoeandroid中的好帖，我转过来的，为的以后查看，大家应该知道有些地方是看不到eoeandroid这个网站的，所以我没有办法啊。为了自己方便，真的是没有办法。(不理解，当我没有说好了，看内容才是最重要的)

 

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");
   
2. Intent it = new Intent(Intent.ACTION_VIEW,URI);
   
3. startActivity(it);

复制代码

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);  

复制代码

1. Uri uri = Uri.parse("tel.xxxxxx");
   
2. Intent it =new Intent(Intent.ACTION_CALL,uri);
   
3. 要使用这个必须在配置文件 中加入<uses-permission id="android .permission.CALL_PHONE" />
