Android close dialog after 5 seconds?

Question

I\'m working on an accesibility app. When the user wants to leave the app I show a dialog where he has to confirm he wants to leave, if he doesn\'t confirm after 5 seconds t

Answer 1

I added automatic dismiss with the time remaining shown in the positive button text to an AlertDialog.

AlertDialog dialog = new AlertDialog.Builder(getContext())
        .setTitle(R.string.display_locked_title)
        .setMessage(R.string.display_locked_message)
        .setPositiveButton(R.string.button_dismiss, null)
        .create();

dialog.setOnShowListener(new DialogInterface.OnShowListener() {
    @Override
    public void onShow(DialogInterface dialog) {
        final Button positiveButton = ((AlertDialog) dialog).getButton(AlertDialog.BUTTON_POSITIVE);
        final CharSequence positiveButtonText = positiveButton.getText();
        new CountDownTimer(AUTO_DISMISS_MILLIS, 100) {
            @Override
            public void onTick(long millisUntilFinished) {
                positiveButton.setText(String.format(Locale.getDefault(), "%s (%d)",
                        positiveButtonText,
                        TimeUnit.MILLISECONDS.toSeconds(millisUntilFinished) + 1));
            }

            @Override
            public void onFinish() {
                dismiss();
            }
        }.start();

    }
});
