alertdialog problems with item divider

Question

I am having a problem with alert dialog. When I create an alert dialog, the default behavior is to display without a divider. I want to get something exactly like the image below

My code is displaying something different like an extra line at the bottom of last list item which I don't want.

 AlertDialog.Builder builder = new AlertDialog.Builder(context);
        AlertDialog alertDialogObject = builder.create();
        builder.setItems(valueList, new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int item) {
                editField.setText(valueList[item]);
                editField.setError(null);
                editField.requestFocus();
            }
        });
        alertDialogObject = builder.create();
        ListView listView=alertDialogObject.getListView();
        listView.setDivider(new ColorDrawable(Color.LTGRAY)); // set color
        listView.setDividerHeight(2); // set height
        alertDialogObject.show();

Can someone help with this? I want to get dialog alert like the first picture above?

It looks like a footer decoration in a ListView, so try to disable footer dividers, then add an empty footer, it should remove the line from the bottom:

listView.setFooterDividersEnabled(false);
listView.addFooterView(new View(context));

Here's an example with a divider

//create dialog
    AlertDialog.Builder builder = new AlertDialog.Builder(context);
    builder.setTitle(title);
    builder.setItems(valueList, new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int item) {
            //do something
        }
    });
    AlertDialog alert =builder.create();
    //set dividers
    ListView listView =alert.getListView();
    listView.setDivider(context.getResources().getDrawable(R.drawable.extraDull));
    listView.setDividerHeight(1);
    //show
    alert.show();

Notice the difference in this code with what you have... look near builder.create()

also you could add this to your color folder
