        intent.putExtra(LiveFolders.EXTRA_LIVE_FOLDER_BASE_INTENT,                new Intent(Intent.ACTION_VIEW, Contacts.CONTENT_URI));这个在用的时候。 如果你用的uri读出来没有一个叫name的表项，那这个ACTION_VIEW会失败，所以需要有个叫name的，作为livefolder显示出来的东西。比如系统的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;这里qb.setProjectionMap(sLiveFoldersProjectionMap); 就是把有一个项作为name显示//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);

自己实现一contentprovider来做这个事情的时候也需要实现一个 name作为显示，
即在cursor query的时候加入比如select xxx as name, 在projection里加。
说不清了。。。
//一般还是不要自己造contentprovider了。。 系统的差不多够用
//问题是怎么在系统里找到所有的uri？ 嘿嘿。我不会－ －

刚起步的时候经常困扰我们的是一些本来容易解决的问题，往往我们会花掉很大的力气去找解决的办法，最后才知道原来这么简单，这就是英文世界造成的。

Intent在 Android应用开发中，占有很大的分量，关于Intent在Android中的作用在网络上已经有很多资料了，这里不再累赘，本人喜欢直来直去。在网上看到很多关于Intent的资料，说那么多，你也许还是一头雾水，到底如何使用Intent呢？这里总结一些重用的Intent使用，仅供参考。

下面直接给我学习的实例片段。



1，掉web浏览器

Uri myBlogUri = Uri.parse("http://kuikui.iteye.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 = { "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，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");

11，直接发邮件

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");

用获取到的Intent直接调用startActivity(returnIt)就ok了。

今天就说这么多，有更大需求的可以看源代码。
