I'm using android emulator 2.2 . My image occupies the screen horizontally but vertically shows a large gap from the Bottom. The image size is 800X600 . should it be re-sized and then used?
Make sure that:
1. Both height and width on both parent and child is fill_parent
2. You are setting the src property and not the background one on the image
Note: You also don't need the layout_x nor layout_y

Problem: trying to give multi device support screen for a simple layout but in Nexus 6 its creating the problem,means not showing fit.
It's side is cutting down where as per as docs for nexus-6 resolution is 1440*2560 and image should be in drawable-xxxhdpi .so i keep a image with resolution of 1440*2560.
<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">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/icon"
android:id="#+id/imv" />
</RelativeLayout>
if i ll give match_parent so obvious it will stretch the image.
Please help me to get out of it.
Here is screen shots of screen -

Set the width of the Image to fill_parent (you can set margins if you want a bit smaller imageView or you could also just set a fixed width)
Use android:adjustViewBounds to keep aspect ratio
Set height to wrap_content (it will take whatever it takes to maintain aspect ratio)
<ImageView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:src="#drawable/icon"
android:id="#+id/imv"
android:scaleType="fitCenter" />
If you want to fit the image on the imageview, replace android:src with android:background in the ImageView in the xml code.
Try to use these lines of code in the layout
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/icon"
android:scaleType="fitXY"
android:id="#+id/imv" />
I have two ImageViews with the same image source inside LinearLayout, but why the second image is smaller than the first?
This is the source code:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:gravity="center_vertical">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/background_landscape" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/background_landscape" />
</LinearLayout>
</RelativeLayout>
The error can be reproduced clearly on 800x1280 pixel resolution.
How can make both images have the same size with the second image cropped on the right side of the screen. (NOT SCALED DOWN)
... why the second image is smaller than the first?
Because the first image gets its real width due to wrap_content value of layout_width attribute. And the second image receives the rest width (width of layout minus width of first image) from LinearLayout, which is obviously smaller, than the real width of the image. That's why it gets scaled down.

You might use ScrollView, which allows children to go out of parent's boundaries.
Update: as mentioned by CommonsWare:
<HorizontalScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scrollbars="false"
>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:gravity="center_vertical">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/background_landscape" />
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="#drawable/background_landscape" />
</LinearLayout>
</HorizontalScrollView>
Like beworker said the first image is getting its width due to the wrap_content and the second image gets the remaining available horizontal space.
Use android:layout_weight="1" in both ImageViews if you want them each to ocuppy half the available screen width
I am working on a android card view. Here is the code that I have now:
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_margin="10dip"
android:orientation="vertical"
android:background="#drawable/drawable_card_bg">
<ImageView
android:id="#+id/photo"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:src="#drawable/test_img" />
....
and the UI looks like:
However this is not what I am looking for. I want the image to be placed on top of the card, with the top, right, left margins to be 10dip from the background card boarder.
Meanwhile, I want to keep the ratio of the image, so don't want to hard-code the width/height of the image view. I want the image width to fit the width of the background card, and the height should be adjusted according to the width.
How should I change the layout parameters to achieve this?
Thank you
Add android:adjustViewBounds="true" to your ImageView in xml in order to let the ImageView adjust its bounds.
It's very easy......... please do this thing. Replace your imageview code using this one
<ImageView
android:id="#+id/photo"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:scaleType="fitXY"
android:adjustViewBounds="true"
android:src="#drawable/test_img" />
If my answer will help you then support this.
Thanks!!!
I've read all there is to read in terms of supporting different screen desnities. And, I have supplied proper variations of the images being display to appropriate folders. However, I am bewildered by something.
The documentation for ImageView says that setting android:layout_width and android:layout_height to "fill_parent"/"match_parent" will result in the image stretching to fill the screen. (This seems necessary since not all screen densities offer the same size/pixel count screens and I don't want those extra few pixels to result in padding on the bottom of the screen)
This seems to work any other time, but is not working for me when the ImageView is placed inside of a Horizontalscrollview and the width of the image is longer than that of the screen.
My code below:
(The activity is set to landscape in my manifest)
<HorizontalScrollView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="#+id/hscrollview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="0dp"
android:fadingEdge="none"
android:scrollbars="none"
android:overScrollMode="never" >
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:padding="0dp"
android:fadingEdge="none"
android:scrollbars="none"
android:overScrollMode="never" >
<ImageView
android:id="#+id/MapImageView"
android:src="#drawable/map"
android:layout_width="wrap_content"
android:layout_height="fill_parent" />
</RelativeLayout>
</HorizontalScrollView>
Edit: I replaced :src with :background to no effect.
This is the effect I get on devices like tablets. Ideally I want the image to fill the entire screen, like it does, below, on a phone with typical 480x800 resolution or the like.
Try using android:scaleType="fitXY" in your ImageView.
This is working for me:
<ImageView
android:id="#+id/main_imageView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_marginTop="42dp"
android:alpha="0.5"
android:src="#drawable/img_alchemy2" />
It is a portrait image that fills the screen in portrait mode, and in landscape it fills it vertically without stretching it horizontally.
I have a LinearLayout (Horizontal) that I am using to display 3 ImageViews. When I first add the ImageViews the last one is shrunk because the images are too big to fit 3 across. Here is what my designer screen looks like:
Notice the third image is shrunk.
To fix this issue I set the following attributes on each ImageView.
width: 0dp
weight: 1
Here is how my images look after setting those attributes:
The problem I am running into is even though the images have been shrunk there is still space at the top and bottom as shown by the blue rectangle in the following image:
My question is, why is this extra padding there and how can I get rid of it?
Thank you
UPDATE - adding my layout file

ImageViews support different ScaleTypes, the default is FIT_CENTER. here are the other options. FIT_CENTER means its going to start out with height and width equal to your image (what your images looked like in the first screen shot before you added weight). What I believe happened is that it then resized the width of the image based on your layout_weight, and maintained the image's aspect ratio by shrinking it to fit the new width. It left the height to be the original height and centered the result.
I think one of the other scale types would do what you want. Maybe CENTER or CENTER_INSIDE
You can use the following code
<Imageview.....
android:adjustViewBounds="true"
..../>
