I made a linear layout with a background image, a png... I don't know how to show it into the layout ( and centered ) keeping proportions... here is the code
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/background">
Obviously image has the same height and width of the display... Any help?? Thanks in advance
=.4.S.=
Thank you all ^^ I solved in this way:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/background"
android:layout_gravity="center"/>
<ListView android:id="#+id/android:list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:divider="#FFFFFF"
android:layout_weight="2"
android:drawSelectorOnTop="false"
android:layout_gravity="center"/>
</FrameLayout>

Android: Scale a Drawable or background image?
I haven't tried it, but it sounds similar to what you're talking about.
If you do not want your picture to be stretched, you can use BitmapDrawable with gravity set us instead of png.
Refer docs: Bitmap

I kept my image size as 320*480 but it shows blank space in vertical sides,Please give some advice.Here is my xml code please suggest me..
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout

add attribute android:scaleType="fitXY" to imageview
I'm having trouble displaying my image within my LinearLayout. I'm trying to get a background color of white and have an ImageView displayed in my LinearLayout and the image and the background color works find, but the image is stretched.
What's a good way to proportion the image show that it displays normal? Any ideas?
<?xml version="1.0" encoding="utf-8"?>

<ImageView
android:src="#drawable/day1"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</ImageView>
</LinearLayout>
</ScrollView>
the imageview takes extra [black] space and i dont know why
ok this imageview should wrap content but instead..
photo explains the problem
this is the code
<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<ImageView
android:id="#+id/map"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/map" /><ImageView
android:id="#+id/blxx"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:paddingBottom="-20dp"
android:src="#drawable/photo" />
<ImageView
android:id="#+id/blxx"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:src="#drawable/blxx" />
</LinearLayout>
</ScrollView>
Try the below:
android:adjustViewBounds="true"
This will remove the extra padded space
first possible reason for your problem:
sometimes when the image is too small, it can't scratch anymore then some limit. after that limit - what happens is what you see - blank space claimed by the imageView where additional scratch of the image was expected. I advice you to take larger picture (with bigger resolution)
Second possible reason:
add to your imageView properties on the xml file the following attribute:
android:scaleType="fitXY"
android:layout_gravity="center"
Above line is centering the image to fit inside your ImageView. Try without it. If not, set gravity to "fill" and try again.
Also remove one of the duplicates of blxx as noted.
hope this ll help you

I'm having the following problem;
I have a LinearLayout with in it a ScrollView, in the ScrollView is some custom view. Now I want to put an image in the background of the LinearLayout and keep the image in its original size. But when I set the background property of the LinearLayout it stretches to fit the full screen. How can I make it so that the image keeps its original size?
My xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/root"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/some_drawable">
<ScrollView
android:id="#+id/scrollview"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
android:fillViewport="true">
<some.custom.layout
android:id="#+id/mainLayout"
android:layout_height="wrap_content"
android:layout_width="fill_parent"
/>
</ScrollView>
</LinearLayout>
Code example for Egor's answer:
<FrameLayout
android:id="#+id/FrameLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="5dp"
>
<ImageView
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:src="#drawable/background"
/>
<LinearLayout
android:id="#+id/LinearLayout1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
>
</LinearLayout>
</FrameLayout>
Try using FrameLayout with an ImageView and LinearLayout inside. For example, try changing the alpha of the image and move it to foreground in your FrameLayout, thus the LinearLayout stays on background. Hope this helps!
<RelativeLayout
android:id="#+id/relLayout"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<android.support.v7.widget.AppCompatImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="#id/layoutLogin"
android:layout_alignLeft="#id/layoutLogin"
android:layout_alignRight="#id/layoutLogin"
android:layout_alignTop="#+id/layoutLogin"
android:adjustViewBounds="true"
android:background="#mipmap/ic_photo_bg"
android:scaleType="fitXY" />
<LinearLayout
android:id="#+id/layoutLogin"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
</LinearLayout>
</RelativeLayout>
Alternatively to ColdForged's suggestion, you could move from LinearLayout to RelativeLayout and use ImageView to show the image instead of changing background to it. The views in RelativeLayout can interfere unlike in LinearLayout.
You might take a look at the InsetDrawable. Either that or it would likely require you to subclass your layout to draw the way you wish as the background element doesn't have the ability you need.
I have a LinearLayout which has a background image (a 9 patched png file).
How can I add padding to left and right so that the background image does not take up the whole width? I have tried android:paddingLeft and android:paddingRight, but that does not change anything.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingLeft="25dip"
android:paddingRight="25dip"
android:background="#drawable/background">
The whole background still stretches the whole screen width.
You should use xml drawable, specially designed for this purposes - Inset Drawable:
http://developer.android.com/guide/topics/resources/drawable-resource.html#Inset
For example:
res/drawable/inset_background.xml:
<?xml version="1.0" encoding="utf-8"?>
<inset xmlns:android="http://schemas.android.com/apk/res/android"
android:drawable="#drawable/your_background_image"
android:insetRight="25dip"
android:insetLeft="25dip" />
and then in your xml layout:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/inset_background">
Ur background drawable should be like this，using android:bottom
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item android:bottom="48dp" android:drawable="#drawable/bg">
</item>
</layer-list>
That doesn't work because padding only acts on the contents of the LinearLayout. By using a second LinearLayout inside this one the padding will take effect. You must define the background color of the first LinearLayout that will be visible in the padding area.
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:paddingLeft="25dip"
android:paddingRight="25dip"
android:background="#FF000000">
<LinearLayout
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#drawable/background">
</LinearLayout>
</LinearLayout>
Note: This is probably also possible by using an XML file for the background.
You can just use
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_marginLeft="25dip"
android:layout_marginRight="25dip"
android:background="#drawable/background">
