Intent之提供常用功能的使用

1，调用web浏览器

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

returnit = new intent(intent.action_view, mybloguri);

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 = { "xiaokai.shi@gmail.com" };

string[] ccs = { "xiaokai.shi@gmail.com" };

returnit.putextra(intent.extra_email, tos);

returnit.putextra(intent.extra_cc, ccs);

returnit.putextra(intent.extra_text, "body");

returnit.putextra(intent.extra_subject, "subject");

returnit.settype("message/rfc882");

intent.createchooser(returnit, "choose email client");

returnit = new intent(intent.action_send);

10，发短信

uri smsuri = uri.parse("tel:100861");

returnit = new intent(intent.action_view, smsuri);

returnit.putextra("sms_body", "shenrenkui");

returnit.settype("vnd.android-dir/mms-sms");

uri smsuri = uri.parse("tel:100861");

returnit = new intent(intent.action_view, smsuri);

returnit.putextra("sms_body", "shenrenkui");

returnit.settype("vnd.android-dir/mms-sms");

11，直接发邮件

uri smstouri = uri.parse("smsto://100861");

returnit = new intent(intent.action_sendto, smstouri);

returnit.putextra("sms_body", "shenrenkui");

uri smstouri = uri.parse("smsto://100861");

returnit = new intent(intent.action_sendto, smstouri);

returnit.putextra("sms_body", "shenrenkui");

12，发彩信

uri mmsuri = uri.parse("content://media/external/images/media/23");

returnit = new intent(intent.action_send);

returnit.putextra("sms_body", "shenrenkui");

returnit.putextra(intent.extra_stream, mmsuri);

returnit.settype("image/png");

uri mmsuri = uri.parse("content://media/external/images/media/23");

returnit = new intent(intent.action_send);

returnit.putextra("sms_body", "shenrenkui");

returnit.putextra(intent.extra_stream, mmsuri);

returnit.settype("image/png");

intent直接调用startactivity(returnit)就ok了。
