Using dialogue box

Question

I am working on a game. I have used two progressbar as a battery on the players. Now I want to simply display a dialogue box when any of the progressbar get emptied. For decreasing the battery I have used the logic of counter which get decreased as collision is detected.

BattryLevelCPU.setProgress(counter--);

Now I want to use dialogue box to display when this counter==0 How I would be able to achieve it? I have tried out like

if counter==0{
    //tried code of dialogue box
}

I haven't got any result except bunch of errors. Could I do something like this??

 If counter==0 {
  showDialog(DIALOG_ALERT);
}`@Override
protected Dialog onCreateDialog(int id) {
  switch (id) {
    case DIALOG_ALERT:
      Builder builder = new AlertDialog.Builder(this);
      builder.setMessage("This ends the activity");
      builder.setCancelable(true);
      builder.setPositiveButton("I agree", new OkOnClickListener());
      builder.setNegativeButton("No, no", new CancelOnClickListener());
      AlertDialog dialog = builder.create();
      dialog.show();
  }
  return super.onCreateDialog(id);
}

private final class CancelOnClickListener implements
    DialogInterface.OnClickListener {
  public void onClick(DialogInterface dialog, int which) {
    Toast.makeText(getApplicationContext(), "Cancle selected, activity continues",
        Toast.LENGTH_LONG).show();
  }
}

private final class OkOnClickListener implements
    DialogInterface.OnClickListener {
  public void onClick(DialogInterface dialog, int which) {
    AlertExampleActivity.this.finish();
  }
} `
