Question

The question may sound tricky….

but, the thing is, I’ve got a custom list view with a checkbox and a textview on every row… I’ve used android:onClick=”checkmethod” to make a process when a checkbox are checked..

here’s a sample code..

public void checkMethod(View v) {
LinearLayout vwParentRow = (LinearLayout)v.getParent();
CheckBox check = (CheckBox) vwParentRow.findViewById(R.id.checkBox_list);
  if (check.isChecked()) {
      //My process goes here
  }else{
      //Another process comes here
  }
}

now, what I want to do is checking the checkboxes if their states are all unchecked…
how can I do this? can someon please help me asap? thanks in advance!!

Answer 1

This is the fastest and simplest approach I know about:

• Add an private int counter as a class member, and initialize it to 0.
• When checkbox is selected – increment counter
• When checkbox is deselected – decrement counter
• Whenever you need to check if no checkbox is checked – just check if counter == 0
