NOTE: I realized after writing this answer that you're trying to use the LibGDX Timer class. In that case, make sure you're using LibGDX Timer and not the java.util.Timer
Looks like the parameters for schedule() are in milliseconds. From the java documentation:
public void schedule(TimerTask task, long delay, long period)
Parameters: task - task to be scheduled. delay - delay in milliseconds before task is to be executed. period - time in milliseconds between successive task executions.
So try passing 1000 and 2000 instead of 1 and 2.
