Detailed explanation of timing pin (refresh page request server) used in Android

I want to use 5 seconds in the program to request data (I don't recommend you to do this, my demand is this)

Code display:

1. Create the timing needle timer in oncreate

2. Create a handler in the thread

3. Create an ID for recycling

4. In case 1, do the requirements that need to be cycled (mine is a 5-second request)

5. Complete!
