Question

everyone.
I’m trying to make a basic tycoon game for Android
and I’m trying to increment the value of text-views every 5 seconds with a timer,
But the textview doesn’t update.
Here’s my code so far:

public class Town extends Activity implements OnClickListener {
Timer timer;
TimerTask task;
TextView goldTV;
TextView woodTV;
TextView foodTV;
TextView stoneTV;
TextView cashTV;
int gold = 20;
int wood = 20;
int food = 20;
int stone = 20;
int cash = 200;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_town);
    goldTV = (TextView) findViewById(R.id.textView1);
    woodTV = (TextView) findViewById(R.id.TextView01);
    foodTV = (TextView) findViewById(R.id.TextView02);
    stoneTV = (TextView) findViewById(R.id.TextView03);
    cashTV = (TextView) findViewById(R.id.TextView04);
    timer = new Timer();
    task = new TimerTask() {

        @Override
        public void run() {
            gold++;
            goldTV.setText(gold);
            try {
                this.wait(2000);
            }
            catch (InterruptedException e){
            }
        }

    };
}
@Override
public void onClick(View arg0) {
    // TODO Auto-generated method stub

}

}

a TimerTask should be used with a Timer object. in your code you never run the task.

edit:
try this instead:

goldTV.postDelayed(new Runnable() {

            @Override
            public void run() {
                gold++;
                goldTV.setText(gold+"");
                goldTV.postDelayed(this,2000);
            }
        }, 2000);
