I'm trying to display an image but for some reason it's only giving me a smaller (unreadable) version. Is there a way to display the image full screen and enable zooming in/out? I used a fragment to display the image--do I need to create another class to extend the particular fragment...? Here is the imageview:
<ImageView
android:id="#+id/imageView1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
android:layout_margin="5dp"
android:scaleType="centerInside"
android:src="#drawable/rules" />
If the image is not appering in the full screen, probably there is an issue with the ImageView container. The ImageView may be "filling the parent" but the parent is not filling the screen.
Other issue may be the scaleType, are you sure your image is the correct size? If you want to stretch it you have to change the scaleType.
How about this :
Get screen dimensions in pixels
and then something like this (IF you want to resize the image):
Android image on tablets and phones
This is not a complete answer to your question but the programming should be straightforward once you know the size of the screen and the size of the image.

I am designing an android app and I need to implement the following interface. I need a round border around this number. For the round border I am using an image with a circle with a gradient border. For the numbers I am using the textview. The problem that I have is that when I debug it, the numbers extremely sharp and clean but the circle is not that sharp. The borders look quite rough. I took a screenshot of it but on the phone the thing is much more evident. I also noticed this when I was using an image and a background. The picture in the background was much more clear than the image on the screen. How can I fix this.
This is the XML that I am using
<ImageView
android:layout_width="270dp"
android:layout_height="270dp"
android:id="#+id/imageView"
android:background="#drawable/b"
android:layout_centerVertical="true"
android:layout_centerHorizontal="true"
/>
Not sure about that image sharpness but you should consider on below points with your ImageView,
Setting the image to the ImageView using android:src="..." rather than android:background="...". src= makes it scale the image maintaining aspect ratio!
You should also use android:adjustViewBounds="true" to make the ImageView resize itself to fit the resealed image.
You can change the way it default scales images using the android:scaleType parameter, use android:scaleType="centerCrop" and see if it gets more clear.
So I'm working on Pacman for Android as a learning exercise. I've got the background set in my activity layout, but I'm having trouble making the background fit properly.
I've tried centerCrop and fitXY, with different results, neither of which work exactly. I want to stretch the view to the dimensions of the screen. It appears however that the image view is restricted to the center, like I have 3 imageviews ... but I have only one.
Any thoughts? Do I have to do some of this in code?
Thanks!
<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"
android:background="#000FFF"
tools:context="srg.pmd.GameActivity"

<ImageView
android:id="#+id/emptyPacman"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="#drawable/blank_screen"
android:scaleType="fitXY"
/>
First screenshot is fitXY
Second is centerCrop
The image you are using must be 320x480 then only the image will fit the screen other wise it will get distorted here is a link for more info about the image size Android: Background Image Size (in Pixel) which Support All Devices .hope it works for u
Well, nuts to me. The actual png file was wrong -- it was a lot wider than I assumed. Taking a closer look with an image editor revealed the problem.
I need to make four imageButtons in my app. Whenever I insert a JPEG image into Android Studio and put it on the imageButton, the button just grows in size so that the image doesn't fit on the button.
I need the button to just stay the same size that I've made it and need the image to fit nicely and be centered on the button. I've tried everything. Does anyone know how to do this? Can this be done with any sized image of any format?
To make your image fill ImageButton then use - android:scaleType="fitXY"
<ImageButton
android:id="#+id/TextButton"
android:layout_width="match_parent"
android:layout_height="45dp"
android:layout_weight="0.5"
android:scaleType="fitXY"
android:src="#drawable/jpeg_image" />
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 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
