android - How to disable outside touching to hide DialogPreference -


i'm developing custom dialogpreference.

when user clicks outside dialog, cancelled , need avoid this.

i know dialog has method setcanceledontouchoutside(boolean cancel) need dialogpreference not.

in onbinddialogview try:

getdialog().setcanceledontouchoutside(true);

but getdialog() returns null.

how can do? can me?

this class:

public class updatepreference extends dialogpreference implements view.onclicklistener{       public updatepreference(context context, attributeset attrs) {         super(context, attrs);         setpersistent(false);         setdialoglayoutresource(r.layout.update_dialog_layout);         setpositivebuttontext("");         setnegativebuttontext("");     }      @override     protected void onbinddialogview(view view) {         super.onbinddialogview(view);            //init components     }      @override     protected void ondialogclosed(boolean positiveresult) {         super.ondialogclosed(positiveresult);      }  }

you can access alerdialog.builder before dialog shown. there can specify builder.setcancelable(false). in such way can achieve desire behavior.

@override protected void onpreparedialogbuilder(builder builder) {     super.onpreparedialogbuilder(builder);     builder.setcancelable(false); }

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
