AlertDialog.Builder builder = new AlertDialog.Builder(this);
            builder.setTitle("Title");
            builder.setItems(items, new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int item) {
                    Toast.makeText(getApplicationContext(), items[item], Toast.LENGTH_SHORT).show();
                }
            });
            AlertDialog alert = builder.create();

I am using above code to show alert dialog , By default it fills the screen in width and wrap_content in height.
How to control the width and height of default alert dialog ?
I tried , alert.getWindow().setLayout(100,100); // It dint work.
How to get the layout params on the alert window and set manually the width and height ?
