Question

I have a menu button called “Restart” which restarts a simple text game I have on the screen using ArrayLists. I’m not sure exactly how to “restart” my application so if the user wants to play a new game I can create new random variables for them and clear the screen.

The optimal code would be something that would just let me restart the application when “restart” is hit on the menu.

Any Ideas?

Thanks

1. Make your activity to draw the views solely on the array list instance variables.
2. It checks for variables onResume too.

3. Create a restart method that deploys the changes in the variable.
   with prototype

   public void restart(View v) {
       //your arraylist initialization here.
       // Call the following method on your top view.
       YourTopView.invalidate();
   }
   

4. In the button declaration in the layout file android:onClick="restart"
