Question

I’m developing an android app for 2.2 ver.

My app must hav such structure:

[ Spinner here (fixed height) ]

[ ListView (not-fixed height) ]

[ ImageView (fixed-height) ]

I have to use only portrait orientation.

I use linearLayout for it. How can I calculate listView height to show spinner on the top of the screen, imageview on the bottom, and listview cover all free space, but not push others away from field of view.

It will be cool to make it dinamic for lots of screen resolutions.

Thank you

Use a relative layout to accomplish what you need.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent" >

    <Spinner
        android:id="@+id/spinner1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true" />

    <ImageView
        android:id="@+id/imageView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:src="@drawable/icon" />

    <ListView
        android:id="@+id/listView1"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_below="@+id/spinner1"
        android:layout_above="@+id/imageView1" />

</RelativeLayout>

By doing this listview will adjust its size so that it fits between the spinner and imageview on your screen
