Android Threading Issues

The scenario is as follows:

1. Start an activity, in the OnCreate () method, open a thread, 5 seconds each interval update ui:textview, from 0 sliding scale, looping 10 times, each time looping log.

2. When looping to the 2nd time, the return key exits the activity and the activity executes the OnDestroy () method.

Result: You will find that although the activity is destroy, the log will still appear 3,4,5,6,7,8,9 until the thread ends.

Conclusion: The threads in activity will not terminate with the disappearance of activity. Therefore, in activity, time-consuming threads need to be managed.
