I am trying to include a ListView within an Activity that is running inside a Dialog. The dialog is basically used to search for bluetooth devices, so I need two Button‘s, a TextView and a ListView. Here is my XML:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="vertical"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent"
  android:padding="20dp">
    <TextView
        android:text="Bluetooth List"
        android:paddingTop="15dp"
        android:textAppearance="?android:attr/textAppearanceMedium"
        android:layout_height="wrap_content"
        android:layout_width="wrap_content">
    </TextView>
    <ListView android:id="@+id/bluetoothPanel_lvBluetooth"
        android:layout_height="match_parent"
        android:layout_width="match_parent"
        android:layout_margin="10dip"
        android:drawSelectorOnTop="false">
    </ListView>
    <LinearLayout
        android:orientation="horizontal"
        android:paddingLeft="4.0dip"
        android:paddingTop="5.0dip"
        android:paddingRight="4.0dip"
        android:paddingBottom="1.0dip"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content">
            <Button
                android:id="@+id/bluetoothPanel_btnSearch"
                android:layout_width="0.0dip"
                android:layout_height="fill_parent"
                android:text="Search"
                android:layout_weight="1.0" />
            <Button
                android:id="@+id/bluetoothPanel_btnCancel"
                android:layout_width="0.0dip"
                android:layout_height="fill_parent"
                android:text="Cancel"
                android:layout_weight="1.0" />
    </LinearLayout>
</LinearLayout>

At the beginning, the ArrayAdapter that is within the ListView is empty, and I am dynamically add elements to it.

The problem is, I want to set a fixed size for the ListView so that it won’t change its size upon adding elements dynamically (List of bluetooth devices are shown). Could you please help me to fix my XML?

EDIT:

I am not talking about array size. I am talking about the listview itself (the view), the height of the listview.
