用Intent调用系统中经常被用到的组件

Uri uri= Uri.parse("http://kuikui.javaeye.com");

returnIt = new Intent(Intent.ACTION_VIEW, uri);

2，地图

Uri mapUri = Uri.parse("geo:38.899533,-77.036476");

returnIt = new Intent(Intent.ACTION_VIEW, mapUri);

3，调拨打电话界面

Uri telUri = Uri.parse("tel:100861");

returnIt = new Intent(Intent.ACTION_DIAL, telUri);

4，直接拨打电话

Uri callUri = Uri.parse("tel:100861");

returnIt = new Intent(Intent.ACTION_CALL, callUri);

5，卸载

Uri uninstallUri = Uri.fromParts("package", "xxx", null);

returnIt = new Intent(Intent.ACTION_DELETE, uninstallUri);

6，安装

Uri installUri = Uri.fromParts("package", "xxx", null);

returnIt = new Intent(Intent.ACTION_PACKAGE_ADDED, installUri);

7，播放

Uri playUri = Uri.parse("file:///sdcard/download/everything.mp3");

returnIt = new Intent(Intent.ACTION_VIEW, playUri);

8，掉用发邮件

Uri emailUri = Uri.parse("mailto:shenrenkui@gmail.com");

returnIt = new Intent(Intent.ACTION_SENDTO, emailUri);

9，发邮件

returnIt = new Intent(Intent.ACTION_SEND);

String[] tos = { "shenrenkui@gmail.com" };

String[] ccs = { "shenrenkui@gmail.com" };

returnIt.putExtra(Intent.EXTRA_EMAIL, tos);
