這個在用的時候。?如果你用的uri讀出來沒有一個叫name的表項， ??

那這個ACTION_VIEW會失敗，所以需要有個叫name的，作為livefolder顯示出來的東西。 ??

??

比如系統的contactsprovider?里面??大概3790行 ??

????????????case?LIVE_FOLDERS_CONTACTS_GROUP_NAME: ??

????????????????qb.setTables(mDbHelper.getContactView()); ??

????????????????qb.setProjectionMap(sLiveFoldersProjectionMap); ??

????????????????qb.appendWhere(CONTACTS_IN_GROUP_SELECT); ??

????????????????selectionArgs?=?insertSelectionArg(selectionArgs,?uri.getLastPathSegment()); ??

????????????????break; ??

??

這里qb.setProjectionMap(sLiveFoldersProjectionMap);?就是把有一個項作為name顯示 ??

//contactsProvider2.java?line?854????

???????sLiveFoldersProjectionMap?=?new?HashMap<String,?String>(); ??

????????sLiveFoldersProjectionMap.put(LiveFolders._ID, ??

????????????????Contacts._ID?+?"?AS?"?+?LiveFolders._ID); ??

????????sLiveFoldersProjectionMap.put(LiveFolders.NAME, ??

????????????????Contacts.DISPLAY_NAME?+?"?AS?"?+?LiveFolders.NAME);??

[java]?view plaincopy

????????intent.putExtra(LiveFolders.EXTRA_LIVE_FOLDER_BASE_INTENT,??

????????????????Contacts.DISPLAY_NAME?+?"?AS?"?+?LiveFolders.NAME);??

自己實現一contentprovider來做這個事情的時候也需要實現一個 name作為顯示，?
即在cursor query的時候加入比如select xxx as name, 在projection里加。?
說不清了。。。?
//一般還是不要自己造contentprovider了。。 系統的差不多夠用?
//問題是怎么在系統里找到所有的uri？ 嘿嘿。我不會－ －?

剛起步的時候經常困擾我們的是一些本來容易解決的問題，往往我們會花掉很大的力氣去找解決的辦法，最后才知道原來這么簡單，這就是英文世界造成的。?

Intent在 Android應用開發中，占有很大的分量，關于Intent在Android中的作用在網絡上已經有很多資料了，這里不再累贅，本人喜歡直來直去。在網上看到很多關于Intent的資料，說那么多，你也許還是一頭霧水，到底如何使用Intent呢？這里總結一些重用的Intent使用，僅供參考。?

下面直接給我學習的實例片段。?



1，掉web瀏覽器?

Uri myBlogUri = Uri.parse("http://kuikui.iteye.com");?

returnIt = new Intent(Intent.ACTION_VIEW, myBlogUri);?

2，地圖?

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

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

3，調撥打電話界面?

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

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

4，直接撥打電話?

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

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

5，卸載?

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

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

6，安裝?

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，掉用發郵件?

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

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

9，發郵件?

returnIt = new Intent(Intent.ACTION_SEND);?

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

String[] ccs = { "shenrenkui@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");?

10，發短信?

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");?

11，直接發郵件?

Uri smsToUri = Uri.parse("smsto://100861");?

returnIt = new Intent(Intent.ACTION_SENDTO, smsToUri);?

returnIt.putExtra("sms_body", "shenrenkui");?

12，發彩信?

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");?

用獲取到的Intent直接調用startActivity(returnIt)就ok了
