How To Pause A SurfaceView Thread From An Android Activity

问题

I have followed this tutorial in great detail and have managed to understand and replicate the functions that I need from an Android SurfaceView:

I need to add a "pause" button in the game, which would be accessed from the activity. How would I go about pausing and then later continuing the thread from the activity?

I have tried adding a button to test it but from that point I can't fathom how to control the thread from the Activity. Any help will be very useful and much appreciated.

Thank you in advance

My opinion to you would be not to pause the thread when the virtual pause button in the game has been pressed, yet rather just alter your update method: eg

if(paused == true) {
// Don't do anything 


} 
else {
// Play
}

Yet to pause a your rendering thread, you can invoke the join() method on the thread.

I hope this helps.

I figured out a simple way to bypass the problem.

All I did was got the pause button to call an activity over the Surfaceview and hence it would pause the view. Then when I close that activity the thread continues from where it left off.
