android - what is correct approach to perform UI related task when a dialog gets dismissed -


i have dialog ondismiss handler:

public class textreaderdialog extends dialogfragment {     ...      public void ondismiss() {      }

i show dialog , add styles part of text fragment:

textreaderdialog d = new textreaderdialog(); d.show(getfragmentmanager(), "sample");  spannable spannabletext = new spannablestring(tv.gettext()); spannabletext.setspan(new backgroundcolorspan(color.ltgray), startoffset, startoffset + w.word.length(), spannable.span_exclusive_exclusive); tv.settext(spannabletext);

whenever dialog dismissed, want remove styles text. how can that? correct way that?

the simplest way go add method fragment so:

public void dismissstyles(){     //do style dismissing here }

now, assume in dialog overriding dialogfragment.ondismiss(dialoginterface dialog). long case, once have completed method, in dialog's ondismiss function, can effect of:

@override public void ondismiss(dialoginterface dialog) {     super.ondismiss(dialog);     myfragment fragment = (myfragment) activity          .getfragmentmanager()          .findfragmentbyid(r.id.containerofyourfragment);     if(fragment != null){          fragment.dismissstyles();     } }

here, activity should current activity fragment , dialog hosted in. can pass dialog in constructor, or depending on dialog located. pass current fragment dialog in constructor well, , called myfragment.dismissstyles();.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
