Question

I am trying to make a simple screen that shows you the amount of money you have earned by the second, so im trying to create a live feed type textveiw that updates every second with the amount of money you have earned, with my code when it runs on my phone it only reads “infinity” and when i tried to add in a 1 second delay it froze all together, here is the code that i wrote, i am using a for loop because i didnt know of a better way if anyone has a better way of achieving what i am trying to do please let me know..

    // Calculate pay per second
    double PPS = (HW/3600);
    double OTPPS = (OTW/3600);
    double HPDPS = (HPD*3600);
    double money = 0;
    double Reserve = 0;
    loc = 0;
    // Display
    for(int i=0; i<HPDPS & loc!=7; i++)
    {
        money = (PPS+Reserve);
        Reserve = (Reserve+money);
        TextView textView = (TextView) this.findViewById(R.id.yourpay);
        textView.setText(String.valueOf(money));
        try {
            Thread.sleep(1000);
        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

Thanks in advance for any help!

Here is an edited version but i am still having a problem where it just displays infinity on the screen, how do i fix this? or how do i use the timer method?

    public void sendMessage(View view) {
    // Receive messages from options page
    Intent intent = getIntent();
    double HW = intent.getDoubleExtra(Options.MESSAGE_HW, 0);
    double OTW = intent.getDoubleExtra(Options.MESSAGE_OTW, 0);
    double HPD = intent.getDoubleExtra(Options.MESSAGE_HPD, 0);
    // Calculate pay per second
    double PPS = (HW/3600);
    double OTPPS = (OTW/3600);
    double HPDPS = (HPD*3600);
    double money = 0;
    double Reserve = 0;
    // Display
    for(int i=0; i<HPDPS; i++)
    {
        money = (PPS+Reserve);
        Reserve = (Reserve+money);
        TextView textView = (TextView) this.findViewById(R.id.yourpay);
        textView.setText(String.valueOf(money));
    }


    // set textView

}

Better way is to user a Timer and TimerTask.

EDIT:
Here is a sample application code to user Timer and TimerTask:

final TextView t1 = (TextView) findViewById(R.id.textView1);

    final Timer t =new Timer();
    t.schedule(new TimerTask() {

        @Override
        public void run() {
            runOnUiThread(new Runnable() {

                @Override
                public void run() {
                    t1.setText("Hello" + counter++); //Place your text data here

                    //Place your stopping condition over here. Its important to have a stopping condition or it will go in an infinite loop. 
                    if(counter == 10)
                        t.cancel(); 
                }
            }); 
        }
    }, 1000, 1000);

Hope this helps.
