android ImageButton scale and maintain aspect ratio

Question

I have a screen that I'm trying to layout...

Basically, I'm trying to evenly distribute 4 ImageButton objects vertically on a screen... I used this here to evenly distribute the items, but now am having a terrible time getting the images to scale but maintain aspect ratio... if I use scaleType="centerInside" they don't scale, if I use "fitXY" they don't maintain aspect ratio... here is what the layout looks like:

and here is the code:

    <LinearLayout
  xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent" android:layout_margin="0dp"
  android:padding="0dp"
  android:orientation="vertical"
  android:weightSum="5"
  >


        <ImageButton android:id="@+id/share_song" 
            android:layout_width="fill_parent" android:text=""
            android:layout_marginLeft="0dp"
            android:layout_marginTop="15dp"
            android:layout_marginRight="5dp"
            android:layout_marginBottom="5dp"
            android:gravity="left" 
            android:src="@drawable/share_song_button_sel"
            android:adjustViewBounds="true"
            android:background="#0000"
            android:scaleType="fitXY"
          android:layout_height="0dp"
          android:layout_weight="1"
            />
        <Button 
            android:layout_width="wrap_content" 
            android:text="" android:id="@+id/tag_a_song"

          android:scaleType="fitXY"/>

            </LinearLayout>
        </LinearLayout> 

</LinearLayout>

Hopefully someone can help.

Set the width of the ImageButtons to fill_parent and use scaletype fitStart for the images that hug the left margin, and fitEnd for the ones on the right. Should do the trick, at least as far as your example image goes. You may have some spacing issues if the proportional width of the images exceed the screen width, but it should work for you.

thx so much for the quick response... i tried that and it doesn't scale the image up... also, if the screen is too small, it won't scale it down. – Tentation

though, i've only been only been checking it out in the wysiwyg editor... maybe i shouldn't be trusting that. – Tentation

Yeah, don't trust it, it's terrible with that sort of thing, in my experience. Try it on the emulator or on a device. – Fructificative

oh yeah... that is crazy... the emulator shows it all good... thx so much for the help! – Tentation

Is it still true as of today? – Apprehensive
