I want to make a dummy progress dialog appear for 2 or 3 seconds. It won't actually do anything other than say detecting. I have the code:
ProgressDialog dialog = ProgressDialog.show(this, "", "Detecting...", true); dialog.show(); dialog.dismiss();But what do I put in between the show, and the dismissal to have the dialog appear for a few seconds? Thanks!

The correct way - it does not block your main thread, so UI stays responsive:
dialog.show();
Handler handler = new Handler();
handler.postDelayed(new Runnable() { public void run() { dialog.dismiss(); }
}, 3000); // 3000 milliseconds delay progress.setProgress(100); Handler handler = new Handler(); handler.postDelayed(new Runnable() { public void run() { pdialog.dismiss(); }}, 3000);You can also use CountDownTimer of Android which is much more efficient than any other solution posted and it also support fires on regular interval through its onTick() method.
Have a look at this example,
new CountDownTimer(3000, 1000) { public void onTick(long millisUntilFinished) { // You don't need anything here } public void onFinish() { dialog.dismiss(); } }.start();You can do something like this:
new AsyncTask<Void, Void, Void>
{ ProgressDialog dialog = new ProgressDialog(MainActivity.this); @Override protected void onPreExecute() { super.onPreExecute(); dialog.setTitle("Please wait"); dialog.setMessage("Preparing resources..."); dialog.setCancelable(false); dialog.show(); } @Override protected Void doInBackground(Void... params) { try{ Thread.sleep(3000); } catch(Exception e) { e.printStackTrace(); } } @Override protected void onPostExecute(Void aVoid) { super.onPostExecute(aVoid); if (dialog!=null && dialog.isShowing()) { dialog.dismiss(); } }
}.execute();Nothing comes between dismiss and show.. the time depending upon you. For example dialog will show before server access and it will dismiss getting result means
dialog.show(); ServerCall(); dialog.close();If you need empty delay means then use CountDownTimer call between that..
In case some one looking for Xamarin.Android (using C#) solution (of Peter Knego's answer), here is how:
new Handler().PostDelayed(() => { dialog.dismiss();
}, 1000);
