How to cancel a running thread

============ Problem Description ============

What I want to do now is to click on one of the 9 buttons on the left to create 10 threads to request 10 pictures from the server, and the trouble I have now is that when I click the left button quickly and randomly, it doesn't create dozens of or even hundreds of threads (tested, too many threads directly causing the phone to die), And I just want the last click of the button to request the picture. Everybody help me to think how to do ah, I was the only one thread to create a request after a picture, then to create a thread to request the next one, or how to do ah! I don't know how to kill a running thread, note: The thread is not looping.
What good ideas are we talking about?

============ Solution 1============

10 threads too many, it is recommended that you use a thread pool to open 4, 5 threads can be reused after all, the thread consumes CPU and memory.
Threads cannot be stopped immediately, you can add a flag bit inside the thread if the threads download the picture successfully without looping,
If you use a thread pool then you don't need it, you can take advantage of threads for a long time and probably open 2 threads.

============ Solution 2============

Use the thread pool, unless it's a high priority, or it's usually a thread pool.

Since you are 10 threads, then you have to judge that these 10 threads are still in the absence, if it is, either do not allow the request, or the request queue ...

Of course upstairs said the thread pool, is also a way,

============ Solution 4============

You can use Intentservice to start the background service load thread, this will only one load, the end of loading one will be a thread off

============ Solution 5============

can submit execution Fututask

Executorservice AA = Executors.newcachedthreadpool (); Futuretask<string> a = new futuretask<string> (new callable<string> () {@Overridepublic String call ()    Throws Exception {return null;}  });  Aa.submit (a); A.cancel (TRUE);
