I am new to Android programming and have done a lot of searching for the answer to this question however I can not find an answer. Maybe I am using the wrong search terms because it seems like a pretty basic request.
I my design (as an example), I would have two text fields defined in my relative layout followed by an image and I would like the image to span the remainder of the screen. Here is what I have so far:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
android:id="#+id/widget29"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android"
>
<ImageView
android:id="#+id/widget38"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/widget37"
android:layout_alignParentLeft="true"
>
</ImageView>
<TextView
android:id="#+id/widget37"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="second view"
android:layout_below="#+id/widget36"
android:layout_alignParentLeft="true"
>
</TextView>
<TextView
android:id="#+id/widget36"
android:layout_width="fill_parent"
android:layout_height="50px"
android:text="first view"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
>
</TextView>
</RelativeLayout>
How do I tell my ImageView to span fill the remainder of the screen. If I define the height and width as "fill_parent" it fills over the two text views.
Thanks in advance for any help you can provide.

It looks like you're just stacking views... it seems to me that this situation would work a lot better with a vertical LinearLayout instead of a RelativeLayout, for one it would be significantly easier to get the image view to span the rest of the space without overlapping your text views:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
android:id="#+id/widget29"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
xmlns:android="http://schemas.android.com/apk/res/android"
>
<TextView
android:id="#+id/widget36"
android:layout_width="fill_parent"
android:layout_height="50px"
android:text="first view"
android:layout_weight="0"
/>
<TextView
android:id="#+id/widget37"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="second view"
android:layout_weight="0"
/>
<ImageView
android:id="#+id/widget38"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1"
/>
</LinearLayout>
In the above example you use layout weights to force relative sharing of the screen space. Setting the weight to zero forces the layout manager to give only requested space to the two text views and since the image view is set to fill parent (with a weight of 1) it receives all of the remaining space
If it's RelativeLayout, then, you will have to do something like this in your ImageView:
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/id_of_your_second_textview"
android:layout_alignParentRight="true"/>

In the picture, I want it to look like Pic1 and Pic2, the problem is, Im making it like Pic3 and I don't want that!
Please update your xml.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"

</LinearLayout>
</RelativeLayout>
Main problem is your textView's width is `"fill_parent". Your texts fill screen because of that.
The problem here is the way you have setup your layout is not the right solution if you wan't to have different layouts for different screens. Your outermost view is a Relative layout with width and height set to fill the screen (that's what fill parent does). Now inside that Relative Layout you have a LinearLayout with width and height set to match its parent (RelativeLayout). So this is also filling your screen. Now inside that you have a text view with width and height set to fill it's parent (LinearLayout), and since LinearLayout is taking full screen, your TextView will fill the whole screen.
The best way to support smaller screen is that in your res directory create a layout-small folder and place the same xml layout file in there but change the dimensions of your textView. If you want the text to be as large as its size, you can do "wrap_content" for both width and height. You can also specify android:textSize in dp to play around with different font sizes.
Try using relative units. I really recommend you to read this:
Supporting Multiple Screens
To make a long story short, using "sp" units is the way to go. use the attribute
android:textSize="15sp"
replacing 15 by the size you think it is the most appropriate for your needs.
Try this:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#1d72c3"
tools:context=".main" >
<LinearLayout
android:layout_width="match_parent"
android:layout_centerInParent="true"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:id="#+id/abus"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center"
android:text="text"
android:textColor="#ffffff" />
<TextView
android:id="#+id/abus"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center"
android:text="text"
android:textColor="#ffffff" />
<TextView
android:id="#+id/abus"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center"
android:text="text"
android:textColor="#ffffff" />
<TextView
android:id="#+id/abus"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center"
android:text="text"
android:textColor="#ffffff" />
</LinearLayout>
</RelativeLayout>
I'm making a layout (XML file) in Android that has two child views (one on the right side of the screen and one on the left). I want the view on the right to take up a pre-determined space (in dp) and have the view on the left take up all the remaining space up to a limit, at which point it will stop expanding and the two layouts will just move further apart as the screen gets larger.
The odd thing is this would be very easy if I wanted the view on the right side to be the one that expands, and the view on the left to be the one that takes up a preset space. If you set each view to the width you want (in a horizontal linear layout) Android will automatically shrink the one on the left in the event that both views don't fit.
I would like to do this in one layout file; this layout is already designed for displays between sw512dp-land and sw765dp-land.
The code below would work if I could find a way to make Android shrink the layout on the left (when layouts both cannot fit at the size specified). But by default the system will shrink the layout on the right first.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal" >
<RelativeLayout
android:id="#+id/left"
android:layout_width="150dip"
android:layout_height="fill_parent"
android:background="#color/red" >
</RelativeLayout>
<LinearLayout
android:id="#+id/right"
android:layout_width="100dip"
android:layout_height="fill_parent"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:background="#color/green" >
</LinearLayout>
This code (from #Lokesh) would work if I didn't need the layout on the left to stop expanding at a certain point.
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="horizontal" >
<LinearLayout
android:id="#+id/left"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_toLeftOf="#+id/right"
android:background="#color/red" >
</LinearLayout>
<LinearLayout
android:id="#+id/right"
android:layout_width="100dip"
android:layout_height="fill_parent"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:background="#color/green" >
</LinearLayout>
It would also be nice to know if anyone thinks this isn't possible so I can resort to doing it pragmatically or changing my approach to the layout.
Thanks!
This works for me. I've set the right layout to 100dip, change as per your needs.
<?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/left"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_toLeftOf="#+id/right"
android:background="#color/red" >
</LinearLayout>
<LinearLayout
android:id="#+id/right"
android:layout_width="100dip"
android:layout_height="fill_parent"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:background="#color/green" >
</LinearLayout>
</RelativeLayout>
EDIT 1: I used the background color just to distinctly show the layouts. Not necessary at all. :)
EDIT 2: If you want a way to expand the left layout upto only a limit then try this -
<?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:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_toLeftOf="#+id/right">
<LinearLayout
android:id="#+id/inner"
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:background="#color/yellow">
<TextView
android:id="#+id/myTextView"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="This will expand only to a limit"
android:maxWidth="300dip"
android:textAppearance="?android:attr/textAppearanceLarge"
android:background="#color/red" />
</LinearLayout>
</LinearLayout>
<LinearLayout
android:id="#+id/right"
android:layout_width="100dip"

Here you need to place your widgets in inner layout and this is what it looks like in different screens.
3.1in HVGA
5.2in QVGA
Colors used : red(#FFFF00), yellow(#FFFFFF00), green(#FF00FF00).
I'm trying to make an Android layout: 3 components inside a vertical LinearLayout. The center component is a ScrollView that contains a TextView. When the TextView contains a significant amount of text (more than can fit on the screen), the ScrollView grows all the way to the bottom of the screen, shows scrollbars, and pushes the last component, a LinearLayout with a Button inside, off the screen.
If the text inside the TextView inside the ScrollView is short enough, the button at the bottom of the screen is positioned perfectly.
The layout I'm trying to achieve is:
The XML for the layout I've written is:
<?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">
<TextView android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textColor="#FFFFFF"
android:layout_marginLeft="10dip"
android:layout_marginRight="10dip"
android:layout_marginTop="10dip"
android:layout_marginBottom="10dip"
android:text="Title />
<ScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content">
<TextView android:id="#+id/text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:autoLink="web"
android:textColor="#FFFFFF"
android:background="#444444"
android:padding="10dip" />
</ScrollView>
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_weight="1">
<LinearLayout
android:orientation="horizontal"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:layout_weight="1"/>
<Button android:id="#+id/login_button"
android:layout_width="0dip"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:layout_weight="1"
android:text="#string/next_button"/>
</LinearLayout>
</LinearLayout>
The scrollview is the second view object and is set to wrap_content, which is more than the screen.
I recommend a RelativeLayout. Top textview first with android:alignParentTop="true", the bottom LinearLayout next with android:alignParentBottom="true" and the scrollview listed last in the xml with the value android:alignBelow="#id/whatYouCallTheHeader.
This will align the bottom bar at the bottom of the screen, and the header at the top, no matter the size. Then the scrollview will have its own place, after the header and footer have been placed.
you should go for relativeLayout rather than LinearLayout. And you can use some properties like alignBelow and all.
Try adding a layout weight into the ScrollView ie.
<ScrollView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1">
This worked for me in a situation almost identical to the one you're presenting but left me wondering why, because it is counter-intuitive that increasing the layout weight of a control from 0 (the default if you don't specify a layout_weight) to 1 should make a control which is already using too much space smaller.
I suspect the reason it works is that by not specifying a layout_weight you actually allow the layout to ignore the size of the scroll view relative to other controls and conversely if do specify one you give it permission to shrink it in proportion to the weights you assign.
![Fixed Header-Footer and scrollable Body layout ][1]
This is what you are looking for . Most of the app in android had this type of layout ,
a fixed header and footer and a scrollable body . The xml for this layout is

I have the following layout for a custom title bar. However, the problem is this: both the imageview and the imagebutton are coming at the centre. I was expecting the imagebutton to be at the extreme right. Can anyone kindly let me know what I did wrong here ? Thanks.
<?xml version="1.0" encoding="utf-8"?>

android:paddingLeft="5dip"
android:background="#323331">
<ImageView
android:src="#drawable/header"
android:id="#+id/header"
android:layout_height="wrap_content"
android:layout_width="fill_parent"

</LinearLayout>
Your layout is only 35dip tall, so pressumibly if you show your ImageView the ImageButton gets positioned outside the screen. Consider changing your layout_height to wrap_content, if appropiate.
You're using a vertically oriented LinearLayout, all View will be presented in a vertical fashion. Use a RelativeLayout so that you'll have more control over where Views are positioned. If you'd still like to use a LinearLayout, you'll have to use horizontal orientation so that the Views can be on the same "line".
Use layout_gravity to layout the item to the right, just gravity is used by the contents of the view.
At first if width is set to fill parent it really fills parent so it use all the width.
Second: why not RelativeLayout? It provides more options and control.
Maybe this is what you looking for:
`
<?xml version="1.0" encoding="utf-8"?>

I'm very new to Android development and I'm trying to figure out how to use the RelativeLayout tag to position my Views. My goal is to have a large TextView on the left, with two ButtonViews to the right of it, stacked on top of each other. Here's the XML code I'm using:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/main_layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/wood_tile">
<TextView
android:id="#+id/life_counter"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="00" />
<Button android:text="#string/button_up"
android:id="#+id/button_up"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="#id/life_counter"/>
<Button android:text="#string/button_down"
android:id="#+id/button_down"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#id/button_up"/>
</RelativeLayout>
I feel that I must not be using the tag properly. Can someone explain how it works? Thanks in advance.
You have the left side TextView's width set to fill_parent, this will make it consume the entire screen. Anything placed to the right of it will be off screen. Use wrap_content or a specific width for the elements within the relative layout.
Your approach is also a bit off. If you want the two buttons aligned to the right of the screen, use this:
<RelativeLayout
android:id="#+id/main_layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView
android:id="#+id/life_counter"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="00" />
<Button android:text="Button Up"
android:id="#+id/button_up"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"/>
<Button android:text="Button Down"
android:id="#+id/button_down"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_below="#+id/button_up"/>
</RelativeLayout>
