java - checkBox is checked ? Looping inside checkbox elements -

int count = listview.getchildcount(); (int = 0; < count; i++) {     view child = list.getchildat(i);     //check child.. } 

i wanted use following code see if total number of checkbox(es) checked or not. if have 3 checkboxes want equivalent to:

if(!list.getchildat(0) && !list.getchildat(1) && !list.getchildat(2)){        // unchecked checkbox } 

how loop through this, because 1 not sure number of contents in checkbox.

just modify if statement return state of checkbox.

int count = listview.getchildcount(); boolean allunchecked = true; (int = 0; < count; i++) {     object child = (object) listview.getchildat(i);     if (child instanceof checkbox) {         checkbox checkboxchild = (checkbox) child;         if (checkboxchild.ischecked()) {             allunchecked = false;   //one checked, sufficient not unchecked             break;    //get out loop         }     } } 

allunchecked true if checkboxes unchecked, false otherwise

i'm not android developer , can't find docs getchildat don't know returns. if object can omit cast.

its check null return of getchildat too.

ps: not code, can take pseudo-code know how implement logic of how checked or not, getting list of checkboxes task :)
