Android DialogFragment not showing when show() called in onCreate of Activity -


i have dialog fragment simple indeterminate progress bar in centre, use show network activity:

public class nativeloadingdialogfragment extends dialogfragment {  public nativeloadingdialogfragment() {     // blank }  @override public dialog oncreatedialog(bundle savedinstancestate) {     dialog dialog = new dialog(getactivity(), android.r.style.theme_dialog);     progressbar indeterminateprogressbar = new progressbar(getactivity());     indeterminateprogressbar.setindeterminate(true);      dialog.requestwindowfeature(window.feature_no_title);     dialog.setcancelable(false);     dialog.setcanceledontouchoutside(false);     dialog.setcontentview(indeterminateprogressbar);      dialog.getwindow().setbackgrounddrawable(             new colordrawable(android.graphics.color.transparent));      return dialog; }  public boolean isshowing() {     return getdialog() != null; } }

i have used dialog fragment throughout app no issues, shows without issue in lots of places when call dialog.show(getfragmentmanager, null), when try call in onresume of settings activity not show!

i have activity settings, launches system settings change language of phone. once user changes language , activity resumes detect if language has changed , network call:

 @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     ...     mloading = new nativeloadingdialogfragment();     if (savedinstancestate != null) {             if (savedinstancestate.containskey(extra_language)) {                 string language = savedinstancestate.getstring(extra_language);                 string currentlanguage = apputils.getdefaultlanguagecode(                         smartbankconstant.default_language,                         smartbankconstant.supported_languages);                 if (!language.equals(currentlanguage)) {                     updatelanguage(language.stringtolanguage(currentlanguage));                 }             }         }    }     private void updatelanguage(language newlanguage) {     ....     getspicemanager().execute(new setlanguagerequest(newlanguage),             new setlanguagerequestlistener(this));           mloading.show(getfragmentmanager(), null);         getfragmentmanager().executependingtransactions();     }

the code runs no dialog appears! if network call fails have retry option calls updatelanguage(language newlanguage) method again, , dialog appears time! doing wrong?

try approach. checks if dialog displayed, otherwise shows it.

@override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     ...     mloading = new nativeloadingdialogfragment();     if (savedinstancestate != null) {         ...     }      mloading.show(getfragmentmanager(), null); }  private void updatelanguage(language newlanguage) {    ...     if (mloading != null && !mloading.isvisible()) {        mloading.show(getfragmentmanager(), null);        getfragmentmanager().executependingtransactions();    } }
