Implementation of authorized user login in Sina Weibo Development

When an authorized user starts an application again, we need to read it from the database.Authorized user informationAllows the user to select the user name to log on. Read the token and tokenSecret from the database and initialize the accessToken to get Weibo data!

Logon interface:

The layout won't go to the code, which is relatively simple and directly goes to the Code:

Package COM. cloay. weibo. ui; import Java. util. hashmap; import weibo4android. weibo; import weibo4android. HTTP. accesstoken; import COM. cloay. weibo. r; import COM. cloay. weibo. bean. userinfo; import COM. cloay. weibo. constants. oauthconstant; import COM. cloay. weibo.

Note 1: Here I only retrieve the first authorized user, and you can retrieve all of them to allow the user to log on.

Through the above code, we can use an authorized user to log on, and use the accessToken method in the Weibo class to request the API for the desired operation!
