maybe try like this:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/RelativeLayout1"
    android:layout_width="wrap_content"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        android:weightSum="100" >

        <LinearLayout
            xmlns:android="http://schemas.android.com/apk/res/android"

Answer 2

this is really easy.. you have 2 approchase: 1) create the root realtivelayout to have android:layout_height="wrap_cotent", and in the same time the ListView to have the same. this will shrink the sizes of the all dialog to the right (no space) size. 2) *more recomended , have the root to be a Linearlayout and give it some wightsum, then put the other views in this root, and give them some layout_wight, this way you know the in any screen resolution you have the same porportion of your screen.
