Intent使用歸納

在android中，intent是乙個將要執行的動作的抽象的描述，一般來說是作為引數來使用，由intent來協助完成android各個元件之間的通訊。以下列出intent常用的用法:

1、呼叫web瀏覽器

uri uri = uri.parse("");

intent intent = new intent(intent.action_view ,uri);

startactivity(intent);

2、在地圖上顯示某個座標 

uri uri = uri.parse("geo:21.803233,-53.829831");

intent intent = new intent(intent.action_view, uri);

startactivity(intent);

3、顯示路徑

uri uri = uri.parse(" startlng&daddr=endlat endlng&hl=en");

intent intent = new intent(intent.action_view, uri);

startactivity(intent);

4、呼叫撥打**介面

uri uri = uri.parse("tel:10086");

intent intent = new intent(intent.action_dial, uri);

startactivity(intent);

5、直接撥打**

需要新增許可權

uri uri = uri.parse("tel.10086");

intent intent =new intent(intent.action_call, uri);

6、傳送簡訊或彩信

intent intent = new intent(intent.action_view);

intent.putextra("sms_body", "the sms text");

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

startactivity(intent);

7、傳送簡訊 

uri uri = uri.parse("smsto:10000");

intent intent = new intent(intent.action_sendto, uri);

intent.putextra("sms_body", "haha");

startactivity(intent);

8、傳送彩信

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

intent intent = new intent(intent.action_send);

intent.putextra("sms_body", "some text");

intent.putextra(intent.extra_stream, uri);

intent.settype("image/png");

startactivity(intent);

或者intent intent = new intent(intent.action_send);

intent.setclassname("com.android.mms", "com.android.mms.ui.composemessageactivity");

intent.putextra("subject", "彩信主題");

intent.putextra("sms_body", "彩信內容");

9、呼叫傳送郵件功能

uri uri = uri.parse("mailto:***@foxmail.com");

intent intent = new intent(intent.action_sendto, uri);

startactivity(intent);

10、傳送郵件 

intent intent = new intent(intent.action_send);

intent.putextra(intent.extra_email, ***@foxmail.com);

intent.putextra(intent.extra_text, "the email body text");

intent.settype("text/plain");

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

或者intent intent = new intent(intent.action_send);

string tos = ;

string ccs = ;

intent.putextra(intent.extra_email, tos);

intent.putextra(intent.extra_cc, ccs);

intent.putextra(intent.extra_text, "the email body text");

intent.putextra(intent.extra_subject, "the email subject text");

intent.settype("message/rfc822");

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

12、解除安裝apk

uri uri = uri.fromparts("package", strpackagename, null);

intent intent = new intent(intent.action_delete, uri);

startactivity(intent);

或者uri uninstalluri = uri.fromparts("package", "***", null);

intent intent = new intent(intent.action_delete, uninstalluri);

13、安裝apk

uri installuri = uri.fromparts("package", "***", null);

intent intent = new intent(intent.action_package_added, installuri);

15、傳送附件

intent intent = new intent(intent.action_send);

intent.putextra(intent.extra_subject, "the email subject text");

intent.putextra(intent.extra_stream, "file:///sdcard/test.***");

sendintent.settype("audio/***");

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

16、market上某個應用信，pkg_name就是應用的packagename

uri uri = uri.parse("market://search?q=pname:pkg_name");

intent intent = new intent(intent.action_view, uri);

startactivity(intent);
