How can I show a few progress bars one by one?

I have to do something like this:

Iterate between a few records of an arraylist.
Show progressdialog for one record
Move to next record
and so on.

I am facing issues in showing progress dialog inside a for loop.

I have tried many variations of TimerTask and run. Here is my latest code of the sample demo application.

//In function of showing progress
for (int i = 0; i < myInfo.size() ; i++){
    Timer timer = new Timer();
    timer.scheduleAtFixedRate(new ProgressTask(timer), 1000, 1000);
}

//Here is the ProgressTask
public class ProgressTask extends TimerTask {
    Timer timer;
    public ProgressTask (Timer timer){
        this.timer = timer;
    }

    @Override
    public void run() {
        progressStatus = progressStatus + 10;
        progressBar.setProgress(progressStatus);
        if (progressStatus == 100) {
            timer.cancel();
        }
    }
}

Result is: I just see the progress dialog for first record. Though it executes for loop for all the records, I have made some mistake in scheduling task or my run thread or timer. Can someone help me with the mistake in my code?

Edit:

Here is the whole Activity's code if that helps.

Solution

Your progresstask executed simultaneously so you get only one progress. So adjust your delay to execute one by one.

Try this

 for (int i = 0; i < 10 ; i++){
        Timer timer = new Timer();
        timer.scheduleAtFixedRate(new ProgressTask(timer),  i * 1000, 1000);
    }

 public class ProgressTask extends TimerTask {
    Timer timer;
    public ProgressTask (Timer timer){
        this.timer = timer;
    }

    @Override
    public void run() {

        progressStatus = progressStatus + 10;
        progressBar.setProgress(progressStatus);
        timer.cancel(); //Cancel timer all time bcoz you create new timer everytime.

    }

}
