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" />

发送SMS/MMS
调用发送短信的程序

Intent it = new Intent(Intent.ACTION_VIEW);   it.putExtra("sms_body", "The SMS text");   it.setType("vnd.android-dir/mms-sms");   startActivity(it);

Intent it=new Intent(Intent.ACTION_SEND);     String[] tos={"me@abc.com"};     String[] ccs={"you@abc.com"};     it.putExtra(Intent.EXTRA_EMAIL, tos);     it.putExtra(Intent.EXTRA_CC, ccs);     it.putExtra(Intent.EXTRA_TEXT, "The email body text");     it.putExtra(Intent.EXTRA_SUBJECT, "The email subject text");     it.setType("message/rfc822");     startActivity(Intent.createChooser(it, "Choose Email Client"));
