Saving authorization information for Sina Weibo Development

In order to facilitate your next use, we need to save the authorization information. Here we use SQLite in the android system to save it! For more information about how to use SQLite, see my article: How to Use SQLite in android download management. For the smoothness of the program, we use the service background to save the user authorization information:

User user = (User) task. getTaskParam (). get ("user"); UserInfo userInfo = new UserInfo (); userInfo. setId ("" + user. getId (); // obtain the user IDuserInfo. setToken (OAuthConstant. getInstance (). getToken (); // get tokenuserInfo. setSecret (OAuthConstant. getInstance (). getTokenSecret (); // get TokenSecretuserInfo. setName (user. getName (); // username userInfo. setDrawable (getBitmap (user. getProfileImageUrl (); // user profile url, which is used to log on with DataHelper dataHelper = new DataHelper (MainService. this); dataHelper. saveUserInfo (userInfo); // save user information

The DataHelper class code is as follows:

Package COM. cloay. weibo. DB; import Java. io. bytearrayinputstream; import Java. io. bytearrayoutputstream; import Java. util. arraylist; import Java. util. list; import COM. cloay. weibo. bean. userinfo; import android. content. context; import android. database. cursor; import android. database.

Otherwise, IDs, tokens, secret list <userinfo> userlist = new arraylist <userinfo> (); sqlitedatabase database = dbhelper. getwritabledatabase (); string SQL = "select user_id, Token, secret, name, drawable from user_info"; cursor = database. rawquery (SQL, new string [] {}); While (cursor. movetonext () {useri Nfo info = new userinfo (); info. setid (cursor. getstring (0); info. settoken (cursor. getstring (1); info. setsecret (cursor. getstring (2); If (isall) {info. setname (cursor. getstring (3); bytearrayinputstream stream = new bytearrayinputstream (cursor. getblob (4); bitmap icon = bitmapfactory. decodestream (Stream); info. setdrawable (icon);} userlist. add (Info);} cursor. close (); closedb (); Return userlist ;}/* ** Record for determining whether the users table contains a userid * @ Param userid * @ return */Public Boolean haveuserinfo (string userid) {Boolean ishave = false; sqlitedatabase database = dbhelper. getreadabledatabase (); string SQL = "select count (*) from user_info where user_id =?

"; Bytearrayoutputstream OS = new bytearrayoutputstream (); // compress bitmap to PNG encoding and stores the user with a quality of 100%. getdrawable (). compress (bitmap. compressformat. PNG, 100, OS); // id I set to 1 by default. Because I only use one account, you can set it to another object [] bindargs = {"1 ", user. GETID (), user. gettoken (), user. getsecret (), user. getname (), OS. tobytearray ()}; database.exe csql (SQL, bindargs); closedb ();}/*** delete users table record * @ Param userid */Public void deluse Rinfo (string userid) {sqlitedatabase database = dbhelper. getreadabledatabase (); database. Delete ("user_info", "user_id =? ", New string [] {userid}); closedb ();}}

Now, all the authorization and authorization information is complete! The next step is to set up the homepage and get Weibo! Please leave a message if you have any questions!Note: Please indicate the source for reprinting!
