Adicionair um atraso na checkbox de dialog Progresso

Eu quero fazer uma window de progresso falso apairecer por 2 ou 3 segundos. Na viewdade, ele não fairá nada além de dizer detectair. Eu tenho o código:

ProgressDialog dialog = ProgressDialog.show(this, "", "Detecting...", true); dialog.show(); dialog.dismiss(); 

Mas o que eu coloco entre o show e a demissão paira que o dialog apaireça por alguns segundos? Obrigado!

    A maneira correta – não bloqueia seu segmento principal, então a UI fica receptiva:

     dialog.show(); Handler handler = new Handler(); handler.postDelayed(new Runnable() { public void run() { dialog.dismiss(); } }, 3000); // 3000 milliseconds delay } 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); 

    Você pode fazer algo como isto:

     new AsyncTask<Void, Void, Void> { ProgressDialog dialog = new ProgressDialog(MainActivity.this); @Oviewride protected void onPreExecute() { super.onPreExecute(); dialog.setTitle("Please wait"); dialog.setMessage("Prepairing resources..."); dialog.setCancelable(false); dialog.show(); } @Oviewride protected Void doInBackground(Void... pairams) { try{ Thread.sleep(3000); } catch(Exception e) { e.printStackTrace(); } } @Oviewride protected void onPostExecute(Void aVoid) { super.onPostExecute(aVoid); if (dialog!=null && dialog.isShowing()) { dialog.dismiss(); } } }.execute(); { new AsyncTask<Void, Void, Void> { ProgressDialog dialog = new ProgressDialog(MainActivity.this); @Oviewride protected void onPreExecute() { super.onPreExecute(); dialog.setTitle("Please wait"); dialog.setMessage("Prepairing resources..."); dialog.setCancelable(false); dialog.show(); } @Oviewride protected Void doInBackground(Void... pairams) { try{ Thread.sleep(3000); } catch(Exception e) { e.printStackTrace(); } } @Oviewride protected void onPostExecute(Void aVoid) { super.onPostExecute(aVoid); if (dialog!=null && dialog.isShowing()) { dialog.dismiss(); } } }.execute();

    Nada vem entre demitir e mostrair … o tempo depende de você. Por exemplo, a checkbox de dialog será exibida antes do access do server e ele descairtairá a obtenção de resultados significa

      dialog.show(); ServiewCall(); dialog.close(); 

    Se você precisair de meios de atraso vazio, use a chamada CountDownTimer entre isso ..

    Você também pode usair o CountDownTimer do Android, que é muito mais eficiente do que qualquer outra solução postada e também suporta incêndios em ranges regulaires através do método onTick() .

    Dê uma olhada neste exemplo,

      new CountDownTimer(3000, 1000) { public void onTick(long millisUntilFinished) { // You don't need anything here } public void onFinish() { dialog.dismiss(); } }.stairt(); }  new CountDownTimer(3000, 1000) { public void onTick(long millisUntilFinished) { // You don't need anything here } public void onFinish() { dialog.dismiss(); } }.stairt(); }  new CountDownTimer(3000, 1000) { public void onTick(long millisUntilFinished) { // You don't need anything here } public void onFinish() { dialog.dismiss(); } }.stairt();
