I am trying to close a ProgressDialog box automatically after 3 seconds. Here is the dialog:

ProgressDialog progress = new ProgressDialog(this);
progress.setTitle("Connecting");
progress.setMessage("Please wait while we connect to devices...");
progress.show();

I have tried a few methods, but I am unable to get any one of them to work. A simple time or anything would hopefully suffice. Thanks.

AsyncTask is okay if you are processing a long running task and then want to cancel it after, but it's a bit overkill for a 3 second wait. Try a simple handler.

    final ProgressDialog progress = new ProgressDialog(this);
    progress.setTitle("Connecting");
    progress.setMessage("Please wait while we connect to devices...");
    progress.show();

    Runnable progressRunnable = new Runnable() {

        @Override
        public void run() {
            progress.cancel();
        }
    };

    Handler pdCanceller = new Handler();
    pdCanceller.postDelayed(progressRunnable, 3000);

Updated adding show/hide:

progress.setOnCancelListener(new DialogInterface.OnCancelListener() {
    @Override
    public void onCancel(DialogInterface dialog) {
        theLayout.setVisibility(View.GONE);
    }
});

  • In doing this, would it be possible to easily add in hide/show relative layouts after the 3000 timer? – Holdfast33 Mar 19 '15 at 19:53

    Yes, you can either add it in the Runnable run() method, but then you'd have to add a runOnUIThread call. Its easier to add a progress onCancelListener(), I've updated the code above. – Gary Bak Mar 19 '15 at 20:02
