Android how to fill parent but leave some space

The title isn't good but i didn't know how else to describe
I have a relative layout with 2 elements, some container and a button at bottom.
I want the container fill all the space in the relativelayout leaving just the space enough to put the button
here is an example:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/mainLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout //i'm using linearlayout as an example, it could be anything here
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignBottom="#+id/b3"
android:gravity="center"
android:orientation="vertical">
</LinearLayout>
<Button
android:id="#+id/b3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:text="asdasdasdasdasdasdasdasd" />
</RelativeLayout>
here is how i want it look like
The red means the relavitive layout, the green the linear layout, and the yellow means the button...
how can i make it?

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout android:layout_width="match_parent"
android:layout_height="match_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
android:background="#color/red"
android:padding="5dp"
>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_above="#+id/b"
android:background="#color/green">
</LinearLayout>
<Button
android:id="#+id/b"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:text="this is the button"
android:background="#color/yellow"/>
</RelativeLayout>

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/mainLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#color/colorAccent">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_alignTop="#+id/b3"
android:layout_margin="4dp"
android:background="#color/colorPrimary"
android:gravity="center"
android:orientation="vertical">
</LinearLayout>
<Button
android:id="#+id/b3"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:text="asdasdasdasdasdasdasdasd" />
</RelativeLayout>

This should give you something close to what you want:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/mainLayout"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout //i'm using linearlayout as an example, it could be anything here
android:layout_width="match_parent"
android:layout_height="0px"
android:layout_weight="3"
android:gravity="center"
android:orientation="vertical">
</LinearLayout>
<Button
android:id="#+id/b3"
android:layout_width="wrap_content"
android:layout_height="0px"
android:layout_weight="1"
android:text="asdasdasdasdasdasdasdasd" />
</LinearLayout>

Android XML Linear Layout Display

Good morning guys,
I am having a bit of trouble resolving an issue and could use some help. I created an XML resource file called comment__layout. For some reason I cannot get the layout to display full screen. Please can you review the XML code and help. As you will see in the screenshot the Comment layout is loaded over the parent layout which is exactly what I want however, I would like the Comment layout to be full screen.

How to automatically set different item height in ExpandableListView?

I'm trying to use ExpandableListView with custom adapter in my project.
There is a result view of my activity with ExpandableListView:
How you can see, some rows doesn't have a right height and some lines are cropped.
What i do wrong?
There are my layout files
activity layout:
<?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">
<ExpandableListView
android:layout_width="matc_parent"
android:layout_height="match_parent"
android:id="#+id/noticeList"/>
<TextView
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:id="#+id/empty"
android:text="#string/empty"/>
</LinearLayout>
and layout for item of ExpandableListView:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal" android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:layout_width="50dp"
android:layout_height="50dp"
android:id="#+id/noticeImage"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:layout_width="fill_parent"
android:layout_height="20dp"
android:id="#+id/noticeDate"/>
<TextView
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:id="#+id/noticeTitle"/>
</LinearLayout>
</LinearLayout>

Thanks all for answers.
The solution is use RelativeLayout instead LinearLayout:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal" android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:layout_width="50dp"
android:layout_height="50dp"
android:id="#+id/noticeImage"/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_toRightOf="#+id/noticeImage"
android:id="#+id/noticeDate"
/>
<TextView
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:id="#+id/noticeTitle"
android:layout_toRightOf="#+id/noticeImage"
android:layout_below="#+id/noticeDate"
/>
</RelativeLayout>

Try to set layout_height for TextView noticeDate to wrap_content
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal" android:layout_width="match_parent"
android:layout_height="wrap_content">
<ImageView
android:layout_width="50dp"
android:layout_height="50dp"
android:id="#+id/noticeImage"/>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/noticeDate"/>
<TextView
android:layout_height="match_parent"
android:layout_width="fill_parent"
android:id="#+id/noticeTitle"/>
</LinearLayout>
</LinearLayout>

Place button next to framelayout

I tried the following:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<FrameLayout
android:id="#+id/recipe_fragment_camera_preview"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:orientation="horizontal" >
<ImageView
android:id="#+id/recipe_fragment_imageview_pattern"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:contentDescription="#string/imageview_description" />
</FrameLayout>
<Button
android:id="#+id/recipe_fragment_button_take_photo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/button_take_photo" />
Unfortunately this isnt working. The FrameLayout is hiding the button because the FrameLayout is taking the whole Screen. I want a button next to the FrameLayout. How can i achiev that?

try like this,
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<FrameLayout
android:id="#+id/recipe_fragment_camera_preview"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:orientation="horizontal" >
<ImageView
android:id="#+id/recipe_fragment_imageview_pattern"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:contentDescription="#string/imageview_description" />
</FrameLayout>
<Button
android:id="#+id/recipe_fragment_button_take_photo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/button_take_photo" />

add in frameLayout and in Button:
android:layout_weight = "2"

just add Weight in FrameLayout
<FrameLayout android:layout_weight="1"
android:id="#+id/recipe_fragment_camera_preview"
android:layout_width="match_parent"
android:layout_height="0dp"
android:orientation="horizontal" >

Try this
<?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">
<FrameLayout
android:id="#+id/recipe_fragment_camera_preview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_above="#recipe_fragment_button_take_photo"
android:orientation="horizontal" >
<ImageView
android:id="#+id/recipe_fragment_imageview_pattern"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:contentDescription="#string/imageview_description" />
</FrameLayout>
<Button
android:id="#+id/recipe_fragment_button_take_photo"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:text="#string/button_take_photo" />
</RelativeLayout>
