Question

I would like to use two ListViews in one screen vertically one below the other and also the two ListView equally take 50%-50% of the screen. My problem is, I created the layout, in eclipse (graphical layout) looks great but in the device it wont take the half of the screen. It seems depends of the content of the ListView. How can I do it right ??

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#f0f0f0"
    android:weightSum="1.0">

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="5dip"
        android:textSize="18sp"
        android:textStyle="bold"
        android:gravity="left"
        android:textColor="#000"
        android:text="Some Text" />

        <ListView
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:layout_marginLeft="10dip"
            android:layout_marginRight="10dip"
            android:layout_weight="0.5"
            android:background="#FB0"
            android:scrollbars="none"
            android:dividerHeight="2dip" />

        <ListView
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:layout_marginLeft="10dip"
            android:layout_marginRight="10dip"
            android:layout_weight="0.5"
            android:background="#FB0"
            android:scrollbars="none"
            android:dividerHeight="2dip" />
</LinearLayout>

You should introduce LinearLayout and use layout_weight, while setting layout_height="0dp".

Here is an example:

<TextView 
    android:layout_width="fill_parent"
    android:layout_height="wrap_content" />

<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

        <ListView
           android:layout_width="fill_parent"
           android:layout_height="0dp"
           android:layout_weight="0.5" />

        <ListView
           android:layout_width="fill_parent"
           android:layout_height="0dp"
           android:layout_weight="0.5" />

</LinearLayout>
