How to run a modal dialog that closes automatically after 10 seconds?

  • 772

I have the following inside the method onCreate()and it must necessarily be there:

do {

AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setTitle(R.string.contacto).setIcon(R.drawable.rudeboys_icon);
builder.setMessage("hola");
builder.show(); } while(timer_dialog<10);

Which shows a dialog with the text "hello" and my timer_dialog that will be my time of 10 seconds, but in the onCreate I don't know how to put it.

In a function I know it is something like :

timer = new CountDownTimer(tiempo_dialog * 1000, 1000) {

        @Override
        public void onTick(long millisUntilFinished) {
            crono.setText("" + String.format(FORMAT, TimeUnit.MILLISECONDS.toHours(millisUntilFinished),
                    TimeUnit.MILLISECONDS.toMinutes(millisUntilFinished) - TimeUnit.HOURS.toMinutes(TimeUnit.MILLISECONDS.toHours(millisUntilFinished)),
                    TimeUnit.MILLISECONDS.toSeconds(millisUntilFinished) - TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(millisUntilFinished))));


        }
        @Override
        public void onFinish() { //finalizar dialog } }

How can I do it ? I have put a do-while , is it the most efficient?

    The Builder is only for building the dialog. Check if it is shown or discard it you have to do in the dialog

    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setTitle(R.string.contacto).setIcon(R.drawable.rudeboys_icon);
builder.setMessage("hola");
final AlertDialog mDialog = builder.create();
// para hacerlo modal
mDialog.setCanceledOnTouchOutside(false);
mDialog.show();

    In your code you create 10 dialogs in a while. Better close the dialogue with an Handlerafter time.

    The Handler:

    new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
            if(null != mDialog && mDialog.isShowing()) mDialog.dismiss();
        }
    }, 10000);

  2. new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                if(builder != null && builder.isShowing()) builder.dismiss();
            }
        }, 10000);

    You add a Handler so that after 10 seconds it closes.

  3. You can use a handler: How to update UI or method after a few seconds?

    For example, if you want to call some method after 10 seconds:

    new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {

            //Llama método deseado.

            }
        }, 10000);

    First you create the dialog and show it, when the dialog is created you can create a handler that calls the method dismiss()to close it. If you are in a Fragment, the context to use would be obtained by getActivity():

    Example:

        AlertDialog.Builder dialog = new AlertDialog.Builder(getActivity());
    dialog.setCancelable(false);
    dialog.setTitle("Dialog & Handler");
    dialog.setMessage("Este dialogo se cerrara en 10 segundos!");
    dialog.setPositiveButton("OK!!!", new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialog, int id) {
            //No action.
        }
    })
            .setNegativeButton("Cancel ", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                //No action.
                }
            });

    final AlertDialog alert = dialog.create();
    alert.show();  //Muestra dialogo.

    //Crea handler, em 10 segundos cierra el dialogo.
    new Handler().postDelayed(new Runnable(){
        public void run(){
            if (alert.isShowing()) {
                alert.dismiss();
            }
        }
    }, 10000); //10 segundos después llama alert.dismiss();

    enter image description here

    As for your code, you are creating and displaying several AlertDialogwhile the value of the variable timer_dialogis less than 10...

    do {
  AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
  builder.setTitle(R.string.contacto).setIcon(R.drawable.rudeboys_icon);
  builder.setMessage("hola");
  builder.show(); 
} while(timer_dialog<10);

    this is wrong , you just need to create an instance of the AlertDialog.

  4. To fix the problem that the screen closes when you click outside, you just have to create the dialog like this:

    AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
  builder.setTitle(R.string.contacto).setIcon(R.drawable.rudeboys_icon);
  builder.setMessage("hola");
  builder.setCancelable(false); // <--- Esta linea agregue.
  builder.show();

    Greetings.

  5. in my case using a DialogFragment, declare the Dialog as final

    before(without adding the timer):

    BottomSheetEsperaConfirmacionPeticion bottomSheet = new BottomSheetEsperaConfirmacionPeticion();

    later:

    final BottomSheetEsperaConfirmacionPeticion bottomSheet = new BottomSheetEsperaConfirmacionPeticion();

    then add a Handler to create the timer

       new Handler().postDelayed(new Runnable(){
                    public void run(){
/*aqui agregas las sentencias que deseas que se ejecuten despues del tiempo transcurrido*/
                        bottomSheet.dismiss();/*en mi caso solo se oculta el Dialog*/
                        }
                    }, 5000);/*temporizador*/
