I've been trying to find an answer to this all of last evening with no luck so I decided to come ask here. I just started getting into front end dev for Android apps and I'm trying to do something really simple that just doesn't work. All I want to do is add an image on the screen and be able to resize it EXACTLY what size I want regardless of proportions. This is the code I'm currently using inside a relative layout:
<ImageView
android:layout_width="400dp"
android:layout_height="200dp"
android:id="#+id/imageView"
android:scaleType="fitXY"
android:layout_alignParentTop="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:src="#drawable/statsus_logo" />
My image is a horizontal rectangle. When I first add it, it shows up inside a small square centered with a bit of padding all around. When I make the width 400dp that square appears to strech almost 100% across the screen however the logo stays the EXACT same size, centered vertically and horizontally inside this imageview container. When I increase the height of the imageview, the logo increases its size but almost as if it was taking the height and using it as a width. I feel like what its trying to do right now is use the height as its width and the only time when its width is the value i put in, is if the height is also the same value and even then there's some extra unwanted padding.
Again, all I want is for this damn image to be the size I tell it to, so if I want it 5dp wide and 100dp tall, it does just that. Can anyone please help? Thank you very much in advance.
Try to add this attribute to your imageview
android:scaleType="fitXY"
Scale type reference
android:scaleType="fitXY" is the way to scale your image however you want without keeping your proportions however my issue was a little bit different... I'm using android studio and for some reason the settings I was using to "add a new image asset" was making my image act the way I described it above... if I just add an image manually by just click and dragging into the folder, then the image works the way I want it... so long story short, the issue was with how I added my new image asset
thanks to everyone for all of your answers and help!

Just putting it out there I rarely work with .xml so I am sorry for the basic question. I have looked around for other solutions but none really seem to be helping my issue.
So I am adding an ImageButton to my login screen, and the actual image is too large. Here is what the image looks like when I place it in and make no adjustments.
The Login button is too big, I want it to fit the size of the login button in the background. So I try to scale it using the resize view handlers, and I also have adjusted android:layout_width=… and the height as well. But when I do that the image does not get resized, just the area it is placed in get's resized. This is what happens
As you can see, it just kind of deletes some parts of the image and adjusts the area the image is in. How can I adjust the actual size of the IMAGE part of the button? This is what I have done in .xml
<ImageButton
android:id="#+id/signinButtonLogin"
android:layout_width="115dp"
android:layout_height="53dp"
android:background="null"
app:srcCompat="#drawable/loginbutton"
tools:layout_editor_absoluteX="13dp"
tools:layout_editor_absoluteY="447dp" />
Sorry if this is a basic question, I am just starting to learn my way around .xml
I get some images of our new designer but found it strange some of them look like this:
I'm trying to overcome it as it displays well on his device and normal image viewer or PC so while I try I found that if I used src if fit one that has clipped from the right and left (this while using background)
however, if I used src it get fit correctly.
some others (using background)
also, I used src it fits correctly.
I'm confused about this issues and can't find a clarification for it when I googled it.
Code For ImageView
<ImageView
android:id="#+id/aa"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:background="#drawable/a123"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
tools:ignore="ContentDescription" />
Hope anyone can suggest me a way to handle them programmatically and how to persuade designer it is from him if it is?
Hope also someone declares me the core of when using src or background
I don't understand what is your problem exactly.
However,backgroundis for simply defining a shape,color,pattern or anything for our View or Layout.
So you can use this attribute for every layout and button or TextView or anything.
Let's say you have created a Circle.xml file which is a shape.If you call background="#drawable/circle" you can make your ImageView to have a Circular shape.
With src in an ImageView for example you put your Image in the ImageView.
You also can adjust the height and width of the displayed image by layout_width or layout_height which you can set both to "Wrap_content" or "match_parent" or any value
For fitting the image the way you want you should play with layout height and width and layout margin values!
1) I was facing the same issue i fixed it by using android:scaleType="fitXY" it will fit the image accordingly but if you use too small image it will be distorted and if you
will use raw image file make sure to use Compressed image without disturbing the
image quality.
2) All views can take a background image.
The src to an ImageView has additional features:
different scaling types
adjustViewBounds for setting bounds to match image dimensions
some transformations such as alpha-setting
And more that you may find in the docs.Source
I am making a lot of ImageButtons where the image aspect does not matter. That is, I do not care if it is stretched. They are invisible buttons to go on top of a background.
Is there an easy way to layout and stretch my ImageButtons through the graphical editor? I do not want to have to test out each possible padding in my xml. I just want to stretch the sides of the images as though it were an Office Word.
Ask if clarification is needed, please.
I'm not really sure to understand your question, but you can use android:scaleType="fitXY" to stretch your images, and android:adjustViewBounds="true" to have them adjust their bounds due to scaling.
I'm not 100% sure about your question neither. If you meant you want to do it in IDE, eclipse allows you to define the button with dragging.
I want to add a image for my android app.
I want to add image like this
ImageView
android:layout_width="match_parent"
android:layout_height="321dp"
android:src="#drawable/welcome"
it need to cover full width ow screen and it height need to be 1/3 screen (i need to add few button bellow this image)
but when i simulate it i did't get my expectation.It will show middle of screen and it does't apply to full width
How can i solve this problem
Thank you
Thank you friends
I tried something like this
I got my results
ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="#drawable/welcome"
Thank you
Please ensure that the image you're using is a 9-patch image. That'll get the thing done. When making a 9-patch image make sure you're enabling it to stretch horizontally.
So I'm trying to put an image inside a scrollview and have the image stretch to fit different sized screens. It'll stretch horizontally, but vertically it always comes out messed up.
I've read so many pages of people with similar problems, but their solutions never work for me. I've tried every different combination possible using different scaleType,layout_width and layout_height, along with trying changing other things around. The closest I've gotten to getting it to work is shown in the code below, using scaleType="centerCrop". It's the only one that stretches the image vertically in ratio, but it cuts off a big chunk of the image from the top and bottom, it'll scroll up and down the image, but only the middle part shows.
The image is a 480x5500 jpeg, if that matters. Originally before I started messing with all that, the app worked just fine on my phone, but then later I realized the image was crunched when I tried it on a tablet. There's gotta be a way to do this in the xml right? I really don't want to have to do things with the image in the java code part. Also I'm hoping to be able to do this using just one image, I don't want to have use a different image for different screen sizes. Please help, thanks.
<?xml version="1.0" encoding="utf-8"?>
<ScrollView
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/scrollView1"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<ImageView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:scaleType="centerCrop"
android:src="#drawable/paper" />
</ScrollView>
may be this help you,
make both height and width wrap_content of ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
and no need ScrollView here.
Try using custom ImageView like AspectRatioImageView mentioned here:

the next sample is more than what you ask for :
http://www.androidviews.net/2012/11/photoview/
https://github.com/chrisbanes/PhotoView/tree/master/sample

hotoview.sample
it fits the image to the screen , plus it allows to zoom in/out using pinching gestures.
