As I mentioned already, you also need to define the string and item (id) resources.
Before I talk about the code in Main class, copy another file - Counter.java ,
from the UPDOWN COUNTER application to the src folder of the TANK FENCE 3
application.
In the Main class, clear all the lines of code inside the onCreate() method
after the variable rllp (of type RelativeLayout.LayoutParams ) is defined.
Then, add the lines of code given in Listing 6-4 .
Note As with other code listings in this topic, Listing 6-4 is from
the final (completed) copy of the file we are working with. So, al-
though we are working with the TANK FENCE 3 application, List-
ing 6-4 shows code from the TANK FENCE GAME 1 application -
containing the final copy of the Main.java file. (The completed
copies may contain slightly modified variable names.)
