Android CheckBox Select all -

Android CheckBox Select all -

i stuck in scenario. have list view multiple items , checkbox in all, have implemented feature when presses select button, list view items checkboxes should selected , vice versa.

now have implement, after pressing select all, if user unchecks of items list items - select button should automatically unchecked.

/** select checkbox functionality here.. */ mcbselectallcontact .setoncheckedchangelistener(new compoundbutton.oncheckedchangelistener() { @override public void oncheckedchanged(compoundbutton buttonview, boolean ischecked) { grouplistadapter = new groupmemberlistadapter( buttonview.getcontext(), ischecked); mlvgroupcontactlist.setadapter(grouplistadapter); if (mcbselectallcontact.ischecked()) { (int = 0; < mbooleanarray.length; i++) { mbooleanarray[i] = true; } } else { (int = 0; < mbooleanarray.length; i++) { mbooleanarray[i] = false; } } } });

you should set setoncheckedchangelistener checkboxes , whenever 1 unchecked, alter mcbselectallcontact unchecked.
