I have a background image that I would like to 1) fill the vertical space, regardless of whether the image's width is greater than the width of the parent, and 2) align the right edge of the image with the right edge of the parent.
Currently scaleType="centerCrop" is giving me (1) but not (2); it centers the image horizontally. Does anyone know how to get it to right-align? Thanks!
EDIT: Tried adding android:layout_alignParentRight="true" to both the relative layout and image view, with no effect.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/relativeLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:layout_gravity="center" >
<ImageView android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:scaleType="centerCrop"
android:src="#drawable/bg"/>
<LinearLayout
android:id="#+id/fg"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
...
You can use
android:layout_alignParentRight="true"
for the Imageview
add these attributes
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
<ImageView
android:id="#+id/view1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:scaleType="centerCrop"
android:src="#drawable/backg_carbon" >
</ImageView>
I think your issue is that the viewbounds do not adjust to the size of the actual image and fill up the width for some reason. Best thing is to check if setting
android:adjustViewBounds to true helps (with the gravity to right of course).
<ImageView android:layout_width="wrap_content"
android:layout_height="fill_parent"
android:adjustViewBounds="true" //This is the added line.
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:scaleType="centerCrop"
android:src="#drawable/bg"/>

I have this linear layout,
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="1dp"
android:layout_marginRight="1dp"
android:background="#color/white"
android:layout_marginTop="1dp"
android:weightSum="1" >
<TextView
android:id="#+id/textView1"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_weight="0.8"
android:gravity="left|center"
android:padding="5dp"
android:text="Policy No."
android:textStyle="bold" />
<ImageView
android:id="#+id/imageView1"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="0.2"
android:src="#drawable/ic_launcher" />
</LinearLayout>
Now i want the image to not scale but the ImageView to match the height of the parent, the TextView height is set to wrap content and that cant be changed. Also, i can't set the imageView height as wrap_content, since it'll change the height of the overall Linear Layout and i can't afford that.

Now what i want is to have the image's size remain the same as it is the second row, even though the first row's height has increased.
Thanks in advance, any help would be appreciated.
add :
android:scaleType="centerInside"
to your ImageView
To perform no scaling, use
android:scaleType="center"
http://developer.android.com/reference/android/widget/ImageView.ScaleType.html
To get what you want, you can do this:
First give your imageviews same fixed height so they won't scale:
android:layout_height="25dp"
Than put gravity to center_vertical:
android:layout_gravity="center_vertical"
So now you have for each imageview:
<ImageView
android:id="#+id/imageView1"
android:layout_width="0dp"
android:layout_height="25dp"
android:layout_weight="0.2"
android:src="#drawable/ic_launcher"
android:layout_gravity="center_vertical" />
It now no longer matters how may lines your textview has, your imageview will stay the same!
Ouput:
Hope this will help you with your problem.
I have an ImageView which is populated from database (the image comes from database). in the database i have images both portrait and landscape!! how can i adjust the imageView to scale it self according to the image width and height. I have tried many ways but no result! any help please!!!!
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<HorizontalScrollView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
>
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/slideshow"
android:orientation="horizontal"
android:padding="0dp"
>
<ImageView
android:layout_width="match_parent"
android:layout_height="300dp"
android:layout_marginRight="5dp"
android:id="#+id/slide1"
android:src="#drawable/ddd"
/>
Try this code. adjustViewBounds attribute makes the ImageView the same size as image that you put in it.
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:adjustViewBounds="true" />
If you need specific width or height change the wrap_content value.
android the image looks too small on screen, how to scale it to fit the screen? wrap_content does not seem to work
<RelativeLayout
android:id="#+id/layout"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ImageView
android:layout_alignParentTop="true"
android:layout_marginTop="100dip"
android:id="#+id/imageview"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:src="#drawable/splash_screen"/>
<ProgressBar
android:layout_alignParentBottom="true"
android:layout_marginBottom="20dip"
android:id="#+id/progressbar"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
</RelativeLayout>
Add the following attribute to your ImageView to get it to scale as you like (will fill the size of your ImageView):
android:scaleType="fitXY"
I would actually change your width attribute as well. Your final XML could look like this:
<ImageView
android:layout_alignParentTop="true"
android:layout_marginTop="100dip"
android:id="#+id/imageview"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="fitXY"
android:src="#drawable/splash_screen"/>
After testing, the following works:
<ImageView
android:layout_alignParentTop="true"
android:layout_marginTop="100dip"
android:id="#+id/imageview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:scaleType="fitXY"
android:src="#drawable/splash_screen"/>
it's your image issue,may be the image contains unnecessarily enlarged background,crop the image,remove unnecessary background and then it will be solved
I am building an app widget and the layout is going to have a View aligned at the bottom of the widget, to hold a TextView and a ImageView, then a View above it to hold the main text. The problem with what I have is that is seems the "top" View is overlapping with the bottom View:
UPDATE
Now I'm thinking the "top" view is not overlapping the bottom view, but that something is cutting off the top of the image. Here is another screenshot:
As you can see, the text is being cutoff at the top of the bottom view, but the image is getting cut of as well. Here is a screenshot with the image not being scaled to 18dp:
I'm extremely confused.
This is the code I'm using:
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/widgetLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"

<RelativeLayout
android:id="#+id/widgetBgLayout"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:paddingTop="10dp"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:background="#drawable/bg_widget"

<RelativeLayout
android:id="#+id/widgetStatusLayout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"

android:layout_alignParentBottom="true"
android:paddingTop="10dp"

<TextView
android:id="#+id/widgetStatus"

android:layout_centerVertical="true"
android:layout_alignParentLeft="true"

<ImageView
android:id="#+id/widgetIcon"
android:src="#drawable/icon"
android:layout_width="18dp"
android:layout_height="18dp"
android:layout_alignParentRight="true"
android:layout_centerVertical="true"
android:scaleType="centerInside"
android:adjustViewBounds="true"
/>
</RelativeLayout>
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical"
android:layout_above="#id/widgetStatusLayout"
android:layout_alignParentTop="true"
>
<TextView
android:id="#+id/widgetTitle"
style="#style/WidgetTitle"
/>
<TextView
android:id="#+id/widgetText"
style="#style/WidgetText"
/>
</LinearLayout>
</RelativeLayout>
</FrameLayout>
I figured it out. I had to set the height of the icon to a higher number (28dp). I don't think the icon is a true rectangle (I had someone else make the icons for me), which probably caused issues with the aspect ratio.
I have a problem with my ImageView. The icons all display correct size, except the last one is always bigger in my ListView.
Can somebody please help?

If i change the ImageView as follows, it is ok but too big:
android:layout_height="wrap_content"
Edit: Problem solved, i needed to reduce the TextSize in the TextViews
is this you list item layout?
android:layout_height="fill_parent"
in your ImageView is probably what is doing it - you likely need to fix the height somewhere otherwise fill_parent can push the height up if its not specified somewhere higher up in the view hierarchy - generally i fix the height it the list item root element
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="50dp"
android:orientation="horizontal" >
or whatever you item height should be.
