android - builder.setInverseBackgroundForced(true) does not work -

i have in code setinversebackgroundforced set true, doesn't appear work. code produces white text on dark background.

here builder code:

public class test {     private void createmylocationdisabledalert() {           alertdialog.builder builder = new alertdialog.builder(this);           builder.settitle("title")             .setinversebackgroundforced(true)             .setmessage(                       "my message")                       .setcancelable(false)                       .setpositivebutton("options",                               new dialoginterface.onclicklistener() {                           public void onclick(dialoginterface dialog, int id) {                               showoptions();                           }                       });           builder.setnegativebutton("cancel",                     new dialoginterface.onclicklistener() {                  public void onclick(dialoginterface dialog, int id) {                      dialog.cancel();                  }             });           alertdialog alert = builder.create();           alert.show();      } } 

what doing wrong? have tried method call in different positions of code block no resolve.

user custom dialog class extending dialogfragment , use show alertdialog.

example:

public class customalertdialog extends dialogfragment {     @override     public dialog oncreatedialog(bundle savedinstancestate) {         alertdialog.builder builder = new alertdialog.builder(this);         builder.settitle("title")             .setinversebackgroundforced(true)             .setmessage("my message")             .setcancelable(false)             .setpositivebutton(                 "options",                  new dialoginterface.onclicklistener() {                  public void onclick(dialoginterface dialog, int id) {                      showoptions();                  }             });         builder.setnegativebutton(             "cancel",             new dialoginterface.onclicklistener() {                 public void onclick(dialoginterface dialog, int id) {                     dialog.cancel();                 }             });         alertdialog alert = builder.create();         return alert;     } }  public class test {     private void createmylocationdisabledalert() {         new customalertdialog().show(getsupportfragmentmanager(), constants.fragmenttagsearch);     } } 

note: using support library compatibility, hence use of getsupportfragmentmanager().
