Look at the code:

 
for (int i=0; i Final int s1=I; 
New Thread () {
@ Override 
Public void the run () {
Super. The run (); 

OkHttpClient okhttp=new OkHttpClient (); 
FormBody. Builder FormBody=new FormBody. Builder (); 
FormBody. Add (" act ", "UploadBase64"); 
FormBody. Add (" imgstr ", m); 
Request requestbuild=new Request. Builder () 
. Url (mConfig. SITE_API). Post (formBody. The build ()). The build (); 
; 

Call lastcall=okhttp. NewCall (requestbuild); 

Try {
The Response of the execute=lastcall. The execute (); 
String text=the execute. Body (). The String (); 

Message Message=handler. ObtainMessage (); 
Message. What=s1; 
//the message. What=1; 
Message. Obj=text; 
Message. SendToTarget (); 
} the catch (Exception e) {
e.printStackTrace(); 
} 


} 
}. The start (); 

} 

Problem: objlist the ArrayList variable number, average data, 4, 5 of which parameters passed m large amount of data, each time I post data to the server always only last 1, 2, a successful,
Expected results: can you read the ArrayList objlist number, all transfer success, and every success a request, request information, to success in the front-end display

Please the teacher teach me, thank you!

Return retstr;

} 

//to use 
Private void Example ()

for (int i=0; i Final int s1=I;

Params [0]=m; 
Params [1]=i.T oString (); 
//create a task, the parameters passed in 
New UploadTask (). The execute (params); 
} 
} 

To replace the Thread + Handler with the Task, the problem here is that final int s1=I; The code triggers the thread synchronization problem, you can use the code I try first, there is a problem to consulting me. In addition the cycle time to create a thread to submit is not recommended. You should put the loop to thread operation. The worker thread is used to deal with this time-consuming operation

Thank you very much for your reply, could you please tell me the operating cycle on the thread can give an example?
