Check all checkboxes, when one checkbox is clicked in Android?

Issue

The thing I’m trying is to check all those checkboxes, when “cbkomplet” is checked.
But it doesn’t work.
Here’s the code I have so far.

CheckBox repeatChkBx  ( CheckBox ) findViewById( R.id.cbkomplet );
        repeatChkBx.setOnCheckedChangeListener(new OnCheckedChangeListener()
        {
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked)
            {
                if ( isChecked )
                {
                    cbreg.isChecked();
                    cbtank.isChecked();
                    cbzoop.isChecked();
                    cbkom.isChecked();
                    cbmaske.isChecked();
                    cbbl.isChecked();

                }

            }
        });

Solution

You want to call setChecked(), not isChecked() on the dependent check boxes. You are simply testing if each of them is checked, then throwing away the result.
