src and background clips image content Android - android

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

Remove whitespace from image in Android Studio

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.

Can't adjust ImageView on Android API below 16

I want to set a background image in my app, which will fill all screen and scale if needed, so I set it in my main_layout.xml like that:
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:adjustViewBounds="true"
android:id="#+id/imageView"
android:src="#drawable/bg_iphone_6_plus" />
and it looks like this
not very good, I need this picture to adjust in width too, actually.
ok, so this works in most cases and with all API's higher 16, but when I run my app on api lower 16 ( minTargetSdk=14 ), I see this:
I have no idea why it shows like that, I have already tried this tutorial, and replaced ImageView with com.inthecheesefactory.thecheeselibrary.widget.AdjustableImageView
but it didn't change anything at all
If your background image is only this gray picture with gradient in the middle, then move the drawable to android:background to parent container. You don't need additional ImageView for that.
But, if you want to set bitmap as background and keep ratio of this image on different devices and orientations, you should use ImageView and its android:scaleType with e.g. "centerCrop" (which usually is the best choice for backgrounds).
Try with replacing android:src property with android:background in your ImageView layout. I think that will solve your issue. If it is still causing the issue then please let me know.

Android XML ImageView

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!

Android notification small and big images sizes

I'm trying to figure out what is the image size used for the notifications in ICS+
As shown here :
I've tried setting the ic_launcher but it was too big and appear to be cut on the image. (48dp for MDPI)
So now i'm using ic_stat_notify which is 24dp for MDPI and it looks pretty small.
I went through all the documentation and I couldn't find any mention of these icons size.
Thank you
You can find more about these icons dimensions in Iconography part of the documentation here
You can use this website in order to calculate the exact dimensions
If you are implementing your view through a xml layout, you can always scale the ImageView to fit a specific size.
From Android: resizing imageview in XML comes the following example:
<ImageView [...]
android:maxWidth="42dp"
android:maxHeight="42dp"
android:scaleType="fitCenter"
android:adjustViewBounds="true"
/>
You can create a custom notification using RemoteViews and then, in that custom notification's layout, you can add an ImageView. Set the source of this ImageView to ic_launcher.png or something else. Now, set the height and width from the layout/xml file as per your requirements.

Change image on click and make it fit in an ImageView

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
