????????intent.putExtra(LiveFolders.EXTRA_LIVE_FOLDER_BASE_INTENT, ??????????????????new?Intent(Intent.ACTION_VIEW,?Contacts.CONTENT_URI)); ??這個(gè)在用的時(shí)候。?如果你用的uri讀出來(lái)沒有一個(gè)叫name的表項(xiàng)， ??那這個(gè)ACTION_VIEW會(huì)失敗，所以需要有個(gè)叫name的，作為livefolder顯示出來(lái)的東西。 ????比如系統(tǒng)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(gè)項(xiàng)作為name顯示 ???????????sLiveFoldersProjectionMap?=?new?HashMap<String,?String>(); ??????????sLiveFoldersProjectionMap.put(LiveFolders._ID, ??????????????????Contacts._ID?+?"?AS?"?+?LiveFolders._ID); ??????????sLiveFoldersProjectionMap.put(LiveFolders.NAME, ??????????????????Contacts.DISPLAY_NAME?+?"?AS?"?+?LiveFolders.NAME);??

????????intent.putExtra(LiveFolders.EXTRA_LIVE_FOLDER_BASE_INTENT,??????????????????new?Intent(Intent.ACTION_VIEW,?Contacts.CONTENT_URI));??這個(gè)在用的時(shí)候。?如果你用的uri讀出來(lái)沒有一個(gè)叫name的表項(xiàng)，??那這個(gè)ACTION_VIEW會(huì)失敗，所以需要有個(gè)叫name的，作為livefolder顯示出來(lái)的東西。????比如系統(tǒng)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(gè)項(xiàng)作為name顯示???????????sLiveFoldersProjectionMap?=?new?HashMap<String,?String>();??????????sLiveFoldersProjectionMap.put(LiveFolders._ID,??????????????????Contacts._ID?+?"?AS?"?+?LiveFolders._ID);??????????sLiveFoldersProjectionMap.put(LiveFolders.NAME,??????????????????Contacts.DISPLAY_NAME?+?"?AS?"?+?LiveFolders.NAME);??
自己實(shí)現(xiàn)一contentprovider來(lái)做這個(gè)事情的時(shí)候也需要實(shí)現(xiàn)一個(gè) name作為顯示，?
即在cursor query的時(shí)候加入比如select xxx as name, 在projection里加。?
說(shuō)不清了。。。?
//一般還是不要自己造contentprovider了。。 系統(tǒng)的差不多夠用?
//問(wèn)題是怎么在系統(tǒng)里找到所有的uri？ 嘿嘿。我不會(huì)－ －?
這里轉(zhuǎn)個(gè)大大的博克?

剛起步的時(shí)候經(jīng)常困擾我們的是一些本來(lái)容易解決的問(wèn)題，往往我們會(huì)花掉很大的力氣去找解決的辦法，最后才知道原來(lái)這么簡(jiǎn)單，這就是英文世界造成的。?
Intent在 Android應(yīng)用開發(fā)中，占有很大的分量，關(guān)于Intent在Android中的作用在網(wǎng)絡(luò)上已經(jīng)有很多資料了，這里不再累贅，本人喜歡直來(lái)直去。在網(wǎng)上看到很多關(guān)于Intent的資料，說(shuō)那么多，你也許還是一頭霧水，到底如何使用Intent呢？這里總結(jié)一些重用的Intent使用，僅供參考。?
下面直接給我學(xué)習(xí)的實(shí)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(diào)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(fā)郵件?
Uri emailUri = Uri.parse("mailto:shenrenkui@gmail.com");?
returnIt = new Intent(Intent.ACTION_SENDTO, emailUri);?
9，發(fā)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(fā)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(fā)郵件?
Uri smsToUri = Uri.parse("smsto://100861");?
returnIt = new Intent(Intent.ACTION_SENDTO, smsToUri);?
returnIt.putExtra("sms_body", "shenrenkui");?
12，發(fā)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(diào)用startActivity(returnIt)就ok了
