I want to align two buttons with a linear layout, one on the left, and one on the right, like the next and previous buttons on an image gallery. I tried to align them but it doesn't work.
XML layout code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="#android:color/white"
android:gravity="bottom" >
<LinearLayout
android:id="#+id/linearLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#android:color/black" >
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="prev"
android:layout_alignParentRight="true" />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="next" />
</LinearLayout>
</LinearLayout>
Actual output:

How can I fix it?
Use a RelativeLayout. There you can set android:layout_alignParentLeft and android:layout_alignParentRight.
This should work for you:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="#android:color/white"
android:gravity="bottom" >
<RelativeLayout
android:id="#+id/relativeLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#android:color/black" >
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="prev"
android:layout_alignParentLeft="true" />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="next"
android:layout_alignParentRight="true"/>
</RelativeLayout>
</LinearLayout>
With Linear Layout
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Prev"/>
</LinearLayout>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Next"/>
</LinearLayout>
With Relative Layout
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Prev"
android:layout_alignParentLeft="true"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Next"
android:layout_alignParentRight="true"/>
</RelativeLayout>
Use Relative layout in your LinearLayout;
Also add android:layout_alignParentLeft="true" to "prev" Button
and android:layout_alignParentRight="true" to "next" Button
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#android:color/white"
android:gravity="bottom"
android:orientation="vertical" >
<RelativeLayout
android:id="#+id/relativeLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#android:color/black" >
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true" <---- ADD this prop
android:text="prev" />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true" <----- ADD this prop
android:text="next" />
</RelativeLayout>
</LinearLayout>
I guess, the simplest solution is to use View in your inner LinearLayout.
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="prev"/>
<View
android:layout_width="0dp"
android:layout_height="0dp"
android:layout_weight="1"/>
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="next"/>
</LinearLayout>
Something 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" >
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:gravity="right" >
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="Button" />
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_toLeftOf="#+id/button1"
android:orientation="vertical" >
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button" />
</LinearLayout>
</RelativeLayout>
</LinearLayout>
The idea is, to create a RelativeLayout as container and put first Button and then stick it to the right of parent view. After that, add Another button inside LinearLayout and set this LinearLayout into the left of first Button.
Here's the result.
ur layout xml should be as shown below
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="bottom"
android:background="#fff">
<RelativeLayout
android:id="#+id/relativeLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#000"
android:layout_gravity="bottom" >
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:text="Pre" />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="Next" />
</RelativeLayout>
</RelativeLayout>
Use a RelativeLayout instead of a LinearLayout you can add the tags android:layout_alignParentRight="true" and android:layout_alignParentLeft="true" on each button.
You can use RelativeLayout like this:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#android:color/white"
android:orientation="vertical" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#android:color/black"
android:gravity="bottom"
android:orientation="horizontal" >
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:text="prev" />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="next" />
</RelativeLayout>
</LinearLayout>
(I used grey instead of white for the screenshot)
Use a FrameLayout and add the layout_gravity attribute in each of the buttons
Do something like this it will surely help you out
<?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"
>
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/Linear"
android:textSize="35dp"
android:layout_margin="90dp"
/>
<LinearLayout
android:id="#+id/linearLayout1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:background="#android:color/black">
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Relative"
/>
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="200dp"
android:text="Constraint" />
</LinearLayout>
</LinearLayout>
Use margin_Start and End to seprate the buttons in the layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="-:Linear Layout:-"
android:textSize="35sp"
android:layout_gravity="center"
android:layout_marginTop="250dp"
tools:ignore="HardcodedText"/>
<LinearLayout
android:id="#+id/linear2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_marginTop="90dp">
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Relative"
tools:ignore="ButtonStyle,HardcodedText"/>
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="200dp"
android:text="Constraint"
tools:ignore="ButtonStyle"
/>
</LinearLayout>
</LinearLayout>

For Better Performance:
Best to put two views left and right and one view between in linear layout rather than relative layout. Use the below code it will also remove the nesting of views .... It will be good in performance perpective :
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/linearLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:gravity="center_vertical">
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="prev" />
<TextView android:text="Hi its working"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1" />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="next" />
</LinearLayout>

I have a little problem defining a Relative Layout. I have a List View with scroll and two buttons always visible at the bottom of the list view. I just would like my two button have 50% of the width, filling the line. This is my code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<Button
android:id="#+id/testbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:text="Save" />
<Button
android:id="#+id/cancelButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_toRightOf="#+id/testbutton"
android:text="Cancel"/>
<ListView android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/LstPeriodOptions"
android:layout_alignParentTop="true"
android:layout_above="#id/testbutton" />
</RelativeLayout>
I tried to introduce the buttons in a Linear Layout and give the gravity=1 with width=0dp but in that case the ListView dissapears. Could you help me please?
Sorry for my english. This is the result I would like to have:
Thanks a lot, best regards.
EDIT: This is what I tried with Linear Layout:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/container" >
<Button
android:id="#+id/testbutton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:text="Guardar" />
<Button
android:id="#+id/cancelButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_toRightOf="#+id/testbutton"
android:text="Cancelar"/>
</LinearLayout>
<ListView android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/LstPeriodOptions"
android:layout_alignParentTop="true"
android:layout_above="#id/container" />
</RelativeLayout>
Did you try with your LinearLayout in this way because this should work. Note all of the property changes. Since I don't know how yours was, I can't point out all of the differences.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<LinearLayout
android:id="#+id/btnLL"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true">
<Button
android:id="#+id/testbutton"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Save" />
<Button
android:id="#+id/cancelButton"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="1"
android:text="Cancel"/>
</LinearLayout>
<ListView android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="#+id/LstPeriodOptions"
android:layout_above="#id/btnLL" />
</RelativeLayout>
Try out as below to set your button in LinearLayout and set it below your ListView:
<LinearLayout
android:id="#+id/laytbtns"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:layout_below="#+id/LstPeriodOptions" >
<Button
android:id="#+id/testbutton"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginRight="5dp"
android:layout_weight="1"
android:text="Save"/>
<Button
android:id="#+id/cancelButton"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:layout_weight="1"
android:text="Cancel" />
</LinearLayout>
Try this..
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<ListView
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="1"
android:id="#+id/LstPeriodOptions"
android:layout_above="#id/testbutton" />
<LinearLayout
android:id="#+id/laytbtns"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dp"
android:layout_below="#+id/LstPeriodOptions" >
<Button
android:id="#+id/testbutton"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginRight="5dp"
android:layout_weight="1"
android:text="Save"/>
<Button
android:id="#+id/cancelButton"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginLeft="5dp"
android:layout_weight="1"
android:text="Cancel" />
</LinearLayout>
</LinearLayout>
I am trying to create a certain layout, that consists of 2 parts a scrollview and a "footer" at the bottom, but always on top of the scrollview. Everything inside the scrollview must be visible (by scrolling).
This is my current code:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/banner" />
<TextView
android:layout_width="fill_parent"
android:paddingTop="1dp"
android:layout_height="3px"
android:background="#DADADA" />
<RelativeLayout
android:id="#+id/InnerRelativeLayout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true" >
<Button
android:id="#+id/button1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_alignParentRight="true"
android:text="Start Connecting" />
<Button
android:id="#+id/button01"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_above="#+id/button1"
android:layout_alignParentLeft="true"
android:text="First use" />
<TextView
android:id="#+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="20dp"
android:text="Welcome to ADB Wireless!"
android:textSize="25sp" />
</RelativeLayout>
</LinearLayout>
But it gives an overlap on small screens & landscape mode. I would only like to have the 2 buttons to be inside the 'footer'. Thank you!
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

I'm wondering how I can align the buttons as the following: Button1 and Button2-2 are supposed to align horizontally, Button2-1 and Button2-2 should align vertically.
[Button2-1]
[other views] [Button1] [Button2-2]
Here is my code but it doesn't work:
<?xml version="1.0" encoding="UTF-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/ButtonGroups"
android:layout_width="fill_parent"

android:orientation="vertical" >
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:orientation="horizontal" >
<Button
android:id="#+id/Button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center" />
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"

EDITED:
To be more clear, I posted more code here and hopefully it could explain my needs better:
What I want is to align the text view horizontally with the image buttons while vertically with the seekbar above it.

Use RelativeLayout. Stacking LinearLayouts is usually not the way to go!
https://developer.android.com/reference/android/widget/RelativeLayout.html
https://developer.android.com/guide/topics/ui/layout/relative.html
Try changing the gravity attribute of the first button (Button 1) to bottom.
As someone suggested, use a RelativeLayout to design this type of pattern! Here's an example for your situation:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/ButtonGroups"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<Button
android:id="#+id/Button2-2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBaseline="#+id/Button1"
android:layout_alignBottom="#+id/Button1"
android:layout_toRightOf="#+id/Button1"
android:text="button 2-2" />
<Button
android:id="#+id/Button2-1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="#+id/Button2-2"
android:layout_alignLeft="#+id/Button2-2"
android:text="button 2-1" />
<Button
android:id="#+id/Button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_marginTop="54dp"
android:text="button 1" />
</RelativeLayout>
I hope this get you started!
Try the code below:
<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent"
android:stretchColumns="*">
<TableRow >
<TextView />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button2-1" />
</TableRow>
<TableRow >
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button1" />
<Button
android:id="#+id/button2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button2-2" />
</TableRow>
</TableLayout>
The trick is to use a blank text view for the empty space in the first row. Let me know if this helps you. :)
Hello all im getting really frustrated with my button, how do i make it so it stays at the bottom of the screen,
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/textView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="TextView" />
<TextView
android:id="#+id/textView2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="TextView" />
<Button
android:id="#+id/button1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Button" />
</LinearLayout>
?
You can do that by replacing the LinearLayout with RelativeLayout like this:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:id="#+id/textView1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/* this puts the textview at the top of the relative layout */
android:layout_alignParentTop="true"
android:text="TextView" />
<TextView
android:id="#+id/textView2"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/* this puts the textview1 at the bottom of the first textview */
android:layout_below="#id/textView1"
android:text="TextView" />
<Button
android:id="#+id/button1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
/* this puts the button at the bottom of the RelativeLayout */
android:layout_alignParentBottom="true"
android:text="Button" />
</RelativeLayout>
Remove the comment lines if you copy and paste the code because are not working in xml...
Add the empty View with weight 1 between your text views and the button. This view will expand over unused space, keeping the button at the bottom.

I want an activity with below layout:
top button
middle(scroll view)
bottom button
I want the bottom button to attach to the bottom of the activity view, and the middle part occupies the rest of the space.
How I can write the layout xml file?
Below doesn't work:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent">
<LinearLayout android:focusable="true"
android:focusableInTouchMode="true" android:layout_width="0px"
android:layout_height="0px" />
<LinearLayout android:orientation="vertical"
android:layout_width="fill_parent" android:weightSum="1" android:layout_height="wrap_content">
<LinearLayout android:orientation="horizontal"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:weightSum="1">
<EditText android:id="#+id/edit_search"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:lines="1" android:hint="发微博内容" android:layout_weight="0.9" />
<Button android:layout_height="wrap_content" android:text="Search"
android:layout_width="wrap_content" android:id="#+id/search_btn"
android:layout_weight="0.1"></Button>
</LinearLayout>
<TextView android:layout_width="fill_parent"
android:layout_height="wrap_content" android:id="#+id/TextView01"
android:paddingTop="5dip" />
<ListView android:layout_width="fill_parent"
android:id="#+id/lv01" android:layout_height="390dp">
</ListView>
<Button android:id="#+id/create_new_btn"
android:layout_height="wrap_content" android:text="我要评论" android:layout_gravity="bottom"
android:layout_width="fill_parent"></Button>
</LinearLayout>
</LinearLayout>
For that case, just take a RelativeLayout, its better for this case and you don't need to take any sub-layout.
Just try this once and post your XML layout here for the further improvement.
From your xml layout code, i can assume, you just want to have:
EditText+Button=>Top,
TextView+ListView=>Middle,
Create New button=>Bottom,
is this the case?
Keep it simple, go with LinearLayout, and play with the weights:
<LinearLayout
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0">
</Button>
<ScrollView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1">
<!-- Stuff in scroll view -->
</ScrollView>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0">
</Button>
</LinearLayout>
#ParashMayani is right..
Here is the implementation :
<LinearLayout android:focusable="true"
android:focusableInTouchMode="true" android:layout_width="fill_parent"
android:layout_height="wrap_content" android:id="#+id/relLayout" android:orientation="horizontal" >
<EditText android:id="#+id/edit_search"
android:layout_width="wrap_content" android:layout_height="wrap_content"
android:lines="1" android:hint="Hello" android:layout_weight="0.7"/>
<Button android:layout_height="wrap_content" android:text="Search"
android:layout_weight="0.3" android:layout_width="wrap_content" android:id="#+id/search_btn" />
</LinearLayout>
<TextView android:layout_width="fill_parent"
android:layout_height="wrap_content" android:id="#+id/TextView01"
android:paddingTop="5dip" android:layout_below="#id/relLayout"/>
<Button android:id="#+id/create_new_btn"
android:layout_height="wrap_content" android:text="我要评论" android:layout_gravity="bottom"
android:layout_width="fill_parent" android:layout_alignParentBottom="true"/>
<ListView android:layout_width="fill_parent"
android:id="#+id/lv01" android:layout_height="0dp" android:layout_above="#id/create_new_btn" android:layout_below="#id/TextView01" />
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<Button android:id="#+id/button1" android:layout_height="wrap_content" android:layout_width="wrap_content" android:text="Button" android:layout_alignParentTop="true" android:layout_alignParentLeft="true"></Button>
<Button android:id="#+id/button2" android:layout_height="wrap_content" android:layout_width="wrap_content" android:text="Button" android:layout_alignParentBottom="true" android:layout_alignParentLeft="true"></Button>
<ScrollView android:id="#+id/scrollView1" android:layout_height="wrap_content" android:layout_width="match_parent" android:layout_below="#+id/button1" android:layout_above="#+id/button2">
<LinearLayout android:id="#+id/linearLayout1" android:layout_width="match_parent" android:layout_height="match_parent"></LinearLayout>
</ScrollView>
</RelativeLayout>
I think something like that would work. The important part in that layout is the android:layout_below and android:layout_above. You can replace the ScrollView with other layouts such as ListView and it will remain below the first button and above the second regardless of how big it gets. Likewise, the buttons have the attributes android:layout_alignParentTop="true" and android:layout_alignParentBottom="true" which will keep them to the top and the bottom of the RelativeView respectively.
