Java Sina Weibo client development step 3

Implementation: "pull-down refresh" and prompt.

The package structure is as follows:

1. Modify myscrollpane with the following key code:

Verticalscrollbar. addadjustmentlistener (New adjustmentlistener (){

Public void adjustmentvaluechanged (adjustmentevent e ){

// The maximum value of the getmaximum () scroll bar is the maximum span.

// Visible size of getvisibleamount ()

Int currentvalue = getverticalscrollbar (). getmaximum ()

-Getverticalscrollbar (). getvisibleamount ();

If (E. getvalue () = currentvalue &&! Friendtl. isloading ()){

Friendtl. addpage ();

}

}

});

2. Modify the friendtimeline and timeline classes. key code:

Try {

If (lastid = long. max_value ){

Statuswapper = TM. getfriendstimeline (0, 0,

New paging (1 ));

} Else {

Statuswapper = TM. getfriendstimeline (0, 0,
Lastid );

}

} Catch (weiboexception e ){

E. printstacktrace ();

}

Note:

Statuswapper = TM. getfriendstimeline (0, 0,
Getfriendstimeline (0, 0,
Lasti)

The method must be added to the timeline API provided by Sina as follows:

Public statuswapper getfriendstimeline (integer baseapp, integer feature, long max_id) throws weiboexception {

Return status. constructwapperstatus (Weibo. Client. Get (

Weiboconfig. getvalue ("baseurl") + "statuses/friends_timeline.json ",

New postparameter [] {

New postparameter ("base_app", baseapp. tostring ()),

New postparameter ("feature", feature. tostring ()),

New postparameter ("max_id", max_id.tostring ())}));

}

3. added the tipdialog class as a prompt.
4. Modify the main class and add fields.

Public static maindialog;

The running result is as follows:
