Answer 1

This should be your inner AsyncTask class, change parameters as you need.

private class yourTask extends AsyncTask {

    String message;
    ProgressDialog dialog;

    public refreshTask(String message) {
        this.message = message;
        this.dialog = new ProgressDialog(PCGridMain.this);
    }

    @Override
    protected void onPreExecute() {
        dialog.setMessage(message);
        dialog.setIndeterminate(true);
        dialog.setCancelable(true);
        dialog.show();  
    }

    @Override
    protected ArrayList doInBackground(String... params) {
        // Some work
    }

    @Override
    protected void onPostExecute(ArrayList result) {
        if(dialog.isShowing())
                    dialog.dismiss();
    }
}

So you may call this class like:

new yourTask('Dialog message').execute();

I hope it solves your issue.
