I'm trying to add a button that can pause the threads that run my
game. It looks like I can basically copy paste the button example, but
it doesn't work.
public GameView(Context context, AttributeSet attributeSet) {
super(context);
getHolder().addCallback(this);
mainThread = new MainThread(getHolder(), this);
timerThread = new TimerThread();
final Button pauseButton = (Button)
findViewById(R.id.pauseButton);
pauseButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
pauseGame();
}
});
}
It runs perfectly without the button object creation/onclicklistener
setting, but with it added it crashes. Am I doing something wrong?
