Question

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();
                    
                }

            }
        });

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.
