I haven't read through all your code, but you should not call
thread.start() in your surfaceCreated method.
Instead, create and start your thread asap and have it paused when
necessary.
When 'onPause()' or when surfaceDestroyed is called, pause your thread
(CupThread).
When 'onResume()' or surfac
If your list-view uses a (list-)adapter (or a subclass of this), did
you try to call notifyDataSetInvalidated() on the adapter?
This will cause your adapter's getView(int position, View convertView,
ViewGroup parent) to be called again and you can handle your changed
list-item in there.

Do *not* use volatile variables. They are not guaranteed to be atomic.
It's just a compiler hint.
Instead, use synchronized blocks:
class MyThread extends Thread {
boolean mPaused;
boolean mStopped;
public void run() {
...
...
mStopped = false;
mPaused = true or false, dep
What about using a ScrollView as your container view?:

Short answer:
Don't use static variables :-)
Somewhat longer answer:
If sub-activities need to access some data held by my main activity, i
usually do create one static variable:
public MyActivity extends Activity {
>> public static final MyActivity ACTIVE_INSTANCE; <<
protected void onCrea
@Override is a so-called annotation.
It does not generate any byte-code/runnable-code.
It just tells the compiler that the method below it is an override of
its super-class' method.
If your super-class changes its signature of onDraw, your compiler
will warn you about the fact that your method (in
