Intent的幾種用法

intent 應該算是android中特有的東西。你可以在intent中指定程式 要執行的動作（比如：view,edit,dial），以及程式執行到該動作時所需要的資料。都指定好後，只要呼叫startactivity()，android系統會自動尋找最符合你指定要求的應用 程式，並執行該程式。

下面列出幾種intent 的用法

顯示網頁:

uri uri = uri.parse("");

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

startactivity(it);

顯示地圖:

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

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

startactivity(it);

路徑規劃:

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

intent it = new intent(intent.

action_dial, uri);  

startactivity(it);  

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

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

要使用這個必須在配置檔案 中加入

傳送sms/mms:

呼叫傳送簡訊的程式

intent it = new intent(intent.action_view);   

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

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

startactivity(it);  

傳送簡訊:

uri uri = uri.parse("smsto:0800000123");   

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

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

startactivity(it);  

傳送彩信:

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

intent it = new intent(intent.action_send);   

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

it.putextra(intent.extra_stream, uri);   

it.settype("image/png");   

startactivity(it);

傳送email:

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

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

startactivity(it);

intent it = new intent(intent.action_send);   

it.putextra(intent.extra_email, "[email protected]");   

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

it.settype("text/plain");   

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

intent it=new intent(intent.action_send);     

string tos=;     

string ccs=;     

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"));   

新增附件:

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

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

startactivity(it);

uninstall apk

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

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

install apk

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

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

play audio

uri playuri = uri.parse("file:///sdcard/download/everything.***");

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

startactivity(it);  

//page, and notice the id from the address bar
