As one can see in the above image there is a lot of white space around the small image in this ImageView layout. How do I remove the white space and make the image view the same size as the actual image it is displaying? If I make the ImageView smaller, it makes the view smaller but still has white space around the image itself. How do I remove it?
Thanks.
add this XML Attribute to the image view declaration:
adjustViewBounds="true"
For example, your ImageView XML would look like this:
<ImageView
android:adjustViewBounds="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
You simply need to do
android:layout_width="wrap_content"
android:layout_height="wrap_content"
in image view.
In addition to that, u can do below things for good practices
you can use ImageView.ScaleType(FIT_XY) but this will change ration of your image and x,y axis expands independently fill your image view
u need to add android:scaleType="fitXY" in xml file image view for it.
you can use ImageView.ScaleType(FIT_CENTER) it will keep ration and expan x,y until one fill your image view
u need to add android:scaleType="fitCenter" in xml file image view for it.
you can find all of the options by navigating this https://developer.android.com/reference/android/widget/ImageView.ScaleType
I've researched some fixes and none of them worked. What did work was changing from a mipmap to a drawable image. I'm getting other errors, but at least the original problem has been fixed.

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've been trying to create a frame around my imageview using a picture of a wooden frame. I turned the woodenframe picture into a 9patch and its still not wrapping around the imageview.
<RelativeLayout
android:id="#+id/ChosenPic"
android:layout_width="match_parent"
android:layout_height="50dp"
android:layout_weight="3"
android:orientation="vertical"
android:padding="10dp" >
<ImageView
android:id="#+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:baselineAlignBottom="true"
android:src="#drawable/ic_launcher" />
<ImageView
android:id="#+id/ImageView02"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_gravity="fill_vertical|fill_horizontal"
android:scaleType="fitXY"
android:src="#drawable/woodenframe" >
</ImageView>
</RelativeLayout>
So this is the ninepatch and i want it to fit around a picture of my choosing no matter the size.
EDIT:
This is what i want.
You have two options. I recommended the first one.
First option:
Put each image view in a separate LinearLayout and apply the 9patch to the LinearLayout it self not the image view
Second option:
Use or set the background resource of the image view in Java to the 9patch resource or the background attr in xml to the 9 patch resource and the src to the image it self.
Note that it better to use a Layer-List and add a combination of two shapes or whatever rather than using a 9patch resource.
Reference:
https://developer.android.com/guide/topics/resources/drawable-resource.html#LayerList
The "nine-patch" frame image that you upload is not a proper nine-patch.
First, it is a jpg. The extension should be .9.png.
Second, the contents are not correct. Specifically:
You need to have a 1px transparent border around the entire image. I do not see that in your jpg, though that just be an artifact of exporting it as a jpg.
You need to define a stretchable region by drawing black pixels in that 1px border. I see no black pixels defining such a region in the uploaded image.
I highly recommend going back and reading the nine-patch documentation again, and trying the draw 9-patch tool for creating a proper nine-patch.
Your 9-Patch is not configured correctly.
It isn't enough to just rename your file. To get it working properly, you have to define certain areas that should be stretched to fit the dimensions of your view.
You can also define paddings for that 9-Patch to inset the content when applying the 9-Patch to your view.
There's a handy tool called "Draw 9-Patch" in the android SDK that helps you defining these areas:
http://developer.android.com/tools/help/draw9patch.html
To start it, simply run the
draw9patch.bat
located in
...\sdk\tools\
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!
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.
I currently working on my personal project in Android. I'm quite a newbie in android development well it's been a months since I've started to self study this but I just can't focus on this one. Well, so here's my problem, first I will discuss what I've made so far:
I've placed a 6 ImageView for each tableRow (six table rows) in a table layout which make it a 6x6 ImageView.
each of the imageView has a default image icon (the default icon from the android drawable).
Once I clicked the ImageView I will change it's Image using setImageDrawable.
the default icon of the android is sized smaller than the images I've placed in which I think 36x36 pixels is the default icon (the android default) wherein my images are in size of 80x80 pixels.
Now here's the problem:
Once I've clicked the image it will successfully changes the image but will also resize the imageView into the size of my image(80x80 px).
well how do I get over this? I've tried setting the ImageView's scale type into fitXY but it has done nothing still my the imageView is resized.
I've also tried changing the wrap_content into fill_parent but nothing also happens (well I just think that it may solve the problem lol)
Here's the property of my ImageView:
<ImageView android:scaleType="fitXY"
android:id="#+id/imageView1"
android:src="#drawable/image0"
android:layout_height="wrap_content"
android:layout_width="wrap_content">
</ImageView>
Any help please? Thanks in advance!
you can set the fix size for the image view into the xml file or by coding through for e.g. here in xml file
<ImageView android:scaleType="fitXY"
android:id="#+id/imageView1"
android:src="#drawable/image0"
android:layout_height="90dp"
android:layout_width="120dp">
</ImageView>
so all image are display with the size 120*90 so when you change the picture it will fit into this imageview
