Removing AlertDialog background

I have a custom layout in my AlertDialog which has a ListView inside. Now I want to remove the black background of the AlertDialog.

           AlertDialog.Builder builder = new AlertDialog.Builder(this);
            LayoutInflater inflater = this.getLayoutInflater();
            View dialogView = inflater.inflate(R.layout.rate_card_layout, null);
            Button close = (Button) dialogView.findViewById(R.id.btnClose);
            close.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View arg0) {

                    dialog.dismiss();
                }
            });


            ListView lv = (ListView)dialogView.findViewById(R.id.listView1);
            RateListAdapter rLAdapter = new RateListAdapter(SActivity.this,
                    listItemsArray);
            lv.setAdapter(rLAdapter);

            builder.setView(dialogView);
            final Dialog dialog = builder.create();

            dialog.show();

I tried adding 

dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));

as usual. But that isn't working.

enter image description here

Any help will be greatly appreciated.

Try This

Add custom dialog style in style.xml 

 <style name="DialogTheme" parent="@android:style/Theme.Dialog">
            <item name="android:windowBackground">@android:color/transparent</item>        
    </style>

In Activity 

Dialog dialog = new Dialog(this, R.style.DialogTheme);

OR 

AlertDialog.Builder builder=new AlertDialog.Builder(this,R.style.DialogTheme);

Try using this to customise your theme. Also Declare AlertDialogCustom iin styles AlertDialog.Builder builder = new AlertDialog.Builder(new ContextThemeWrapper(this, R.style.AlertDialogCustom));

And then style it like you want:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <style name="AlertDialogCustom" parent="@android:style/Theme.Dialog">
        <item name="android:textColor">#00FF00</item>
        <item name="android:typeface">monospace</item>
        <item name="android:textSize">10sp</item>
         ............. //background etc
    </style>
</resources>

Try

private void updateLayoutParams() {
    Window window = getDialog().getWindow();
    WindowManager.LayoutParams params = window.getAttributes();
    params.dimAmount = 0.2f;

    int margin = getResources().getInteger(R.integer.common_margin);
    DisplayMetrics metrics = new DisplayMetrics();
    ((WindowManager) getActivity().getSystemService(Context.WINDOW_SERVICE)).getDefaultDisplay().getMetrics(metrics);
    params.width = metrics.widthPixels-margin;

    window.setAttributes(params);
    window.setBackgroundDrawableResource(android.R.color.transparent);
    getDialog().setCanceledOnTouchOutside(false);

}
@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);
    Log.d(TAG, "onConfigurationChanged");

    updateLayoutParams();
}
