Android Linear/Relative Layout - how to "auto size" object in the middle (3 objects)

I have two cases with Linear (also tried Relative) layout in android. The one happens for horizontal and the other for vertical. Lets start with the horizontal:

it is something like:

<LinearLayout ... >   
    <Button ...  layout:gravity = "left" layout:width = "wrap_content"/>
    <TextView ... layout:width = ??????? />
    <Image  .... layout:gravity = "right" layout:width = "wrap_content"/>
</LinearLayout>

Well , I want the button to stay at the left, the image to stay at the right(stick to the end , not just right of the text view) and the textview to (probably with an autowidth or whatever) to stay in the middle. If I put in textview width = "fill/match_parent it sends the image out of the screen. If I put wrap_content, then the image does not stay at the right of the screen. I have also tried relative layout without success.

Same case in vertical , where I have something like:

<LinearLayout ...>
    <LinearLayout .... layout:height = "wrap_content" layout:gravity= "top" />
    <ListView layout:height = ???????>
    <LinearLayout ... layout:height = "wrap_content" layout:gravity = "bottom" />
</LinearLayout>

Same requirement here. I want the first L.layout to stay on top, List view auto size between them and the 2nd Linear layout to stay at the bottom. (Imagine I'm trying to create a view that looks like a UITableView in iPhone that has a NavigationBar, the list of items and a ToolBar at the bottom. Fist LinearLayout is the NavigationBar, the LIst view are the cells and the second LinearLayout is the ToolBar).

Any suggestions? Would prefer the xml solutions.
