dialog box with multiple checkboxes android souce code
<p>I have an android app with a button. When clicking the button I need on the screen a dialob box with multiple check boxes annd an ok button. How to do that? Do i need an xml layout for the list with checkboxes?</p>

<p><strong>1. How to add to each element in the list dialog box a check box?</strong></p>

<p><strong>2. How to put in a string all the checked elements when the button OK is pressed.</strong></p>

<p>this is my code so far:</p>

<pre><code> app_part.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {


                final String items[] = {"1","2","3","4"};

                AlertDialog.Builder ab=new AlertDialog.Builder(ConferenceClass.this);
                ab.setTitle("SIP CONTACTS");
                ab.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface d, int choice) {
                    // on OK button action
                    }
                    });
                ab.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface d, int choice) {
                    // on Cancel button action
                    }
                    });
                ab.setItems(items, new DialogInterface.OnClickListener() {


                public void onClick(DialogInterface d, int choice) {


                }
                });
                ab.show();
                 //open contact list and select persons


                }
        });
</code></pre>
