How can I prevent the ImageButton from stretching the image?
Using this snippet:
<ImageButton
android:src="#drawable/prediction"
android:background="?android:attr/selectableItemBackground"
android:gravity="center_horizontal"
android:scaleType="centerInside"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:contentDescription="some description"
android:text="#string/predict"
local:MvxBind="Click ExecuteQueryCmd" />
I get the following effect:
Image is 64x64 png.
All I want is for the ImageButton to respect native width and length, hence resolution, of the image it is being assigned. Recommendations based on a similar post is to use a Button, set its background to an image then use custom selectors but this sounds like a hack. Or is this the proper way to do this?
It work for me with
<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:background="#android:color/transparent"
android:contentDescription="some description"
android:scaleType="centerInside"
android:src="#drawable/ci_icon"
android:text="#string/predict"
local:MvxBind="Click ExecuteQueryCmd" />
Put your image in android:src attribute
Set the width of the ImageButtons to fill_parent and use scaletype fitStart for the images that hug the left margin, and fitEnd for the ones on the right. Should do the trick, at least as far as your example image goes. You may have some spacing issues if the proportional width of the images exceed the screen width, but it should work for you.
Do this:
<ImageButton
android:src="#drawable/prediction"
android:background="?android:attr/selectableItemBackground"
android:scaleType="fitXY"
android:adjustViewBounds="true"
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:contentDescription="some description"
android:text="#string/predict"
local:MvxBind="Click ExecuteQueryCmd" />

In my Image Buttons, there is a lot of white space around the source image. Is it possible to remove this space so that the imagebutton just surrounds the source image itself.
<ImageButton
android:id="#+id/story_1"
android:src="#drawable/my_story"
style="?android:attr/borderlessButtonStyle"
android:layout_width="55dp"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:scaleType="fitXY"
android:contentDescription="Add my story" />
Try this
<ImageButton
android:id="#+id/story_1"
android:src="#drawable/my_story"
style="?android:attr/borderlessButtonStyle"
android:background="#null"
android:layout_width="55dp"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:scaleType="fitXY"
android:contentDescription="Add my story" />
Probably the problem caused by the image transparency. Try remove the white spaces around the image and make those areas transparent.
make sure the original image you are using doesn't have too much white since you already have the solution in your xml scaleType="fitXY" you can try scaleType="fitCenter" but your image is already stretched to fit your entire button in the orginal code
How can I get an ImageButton that has a fixed height and is only as wide as it needs according to the ratio of its source image?
I tried the following:
<ImageButton
android:layout_width="wrap_content"
android:layout_height="8pt"
android:minWidth="0pt"
android:scaleType="fitCenter"
android:adjustViewBounds="true"
android:src="#drawable/list_download"
android:background="#android:color/black"
android:padding="0pt"/>
I set background to black just to see the boundaries of it exactly, and here is the outcome.
I have seen some solutions that suggest to use negative paddings but it is not an elegant solution. There should be a better one.
I tried similar configurations on an ImageView too, but it also had extra padding. So it's not an ImageButton specific problem (i.e. it is not related to this nine-patch issue).
EDIT: If I change scaleType from fitCenter to fitStart, then the outcome is like this. So there is somehow a minimum width.
It's because you've set a limited height. That limits the image height, but when Android calculates the width of the content (the original unrezised image), it's wider.
You'll get the image without the black "padding" on the side if you use wrap_content for the height as well.
<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:minWidth="0pt"
android:scaleType="fitCenter"
android:adjustViewBounds="true"
android:src="#drawable/list_download"
android:background="#android:color/black"
android:padding="0pt"/>
So, if you want the picture to be a specific size, you could resize it in your drawable folder to the size you want.
you just need use android:scaleType="fitXY" and set padding 0dp.
<ImageButton
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="fitXY"
android:padding="0dp"/>
you can put it in a Frame like so :
<FrameLayout
android:layout_width="wrap_content"
android:background="#android:color/black"
android:layout_height="wrap_content">
<ImageView
android:src="#drawable/list_download"
android:scaleType="fitCenter"
android:layout_height="wrap_content"
android:layout_gravity="center"
android:layout_width="8dp"/>
</FrameLayout>
it will be much easier to play with it like so
Here is a small gif of my current situation. I guess many images are better than many words.
As you notice, when I switch for the smaller image, the seekbar size changes. I know this is because of the seekbar's width being set to match_parentand the image's width to wrap_content.
What I don't know is how to overcome this problem, as I can't really hardcode width value otherwise it'll probably get messed up on various screensizes.
So my question is :
Is there a way to prevent this behaviour that is clean? I could simply get the width at runtime and set it as minimal width and it would probably work (heck, I could try it now to make sure), but that is just a horrible thing to do code-wise.
Ideally, I'm guessing there is a way to prevent this in the .xml file, but I couldn't figure it out, playing with the different paddings, margins, scaling and layout sizes.
Here is what you're looking at :
<RelativeLayout
android:layout_weight="1"
android:layout_width="match_parent"
android:layout_height="0dp">
<ImageButton
android:background="#android:color/transparent"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="center"
android:id="#+id/playButton"
android:layout_alignParentLeft="true"
android:layout_marginLeft="30dp"
android:layout_centerVertical="true"
android:src="#drawable/play"
android:onClick="PlayButtonClicked" />
<SeekBar
android:max="100"
android:id="#+id/volumeSeekBar"
android:layout_centerVertical="true"
android:layout_margin="15dp"
android:layout_height="wrap_content"
android:layout_width="match_parent"
android:layout_toRightOf="#+id/playButton"
android:layout_toLeftOf="#+id/muteButton" />
<ImageButton
android:background="#android:color/transparent"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="center"
android:id="#+id/muteButton"
android:layout_alignParentRight="true"
android:layout_marginRight="30dp"
android:layout_centerVertical="true"
android:onClick="MuteButtonClicked"
android:src="#drawable/sound" />
</RelativeLayout>
Ideally it would be nice for the volume icons to be of the same size.
If that is not an option, try replacing android:layout_toLeftOf="#+id/muteButton" with android:layout_marginRight="15dp+30dp+largest_icon_width_in_dp"
where 15dp is your seekbar right margin, 30dp is the mute button right margin.
The third option would be to set a fixed width for the mute button equal to the width of the largest image.
I'd like to have a simple player view with image, name and status. The image will be loaded via Google+.
The Problem I have is that with big images my ImageView get's far too wide and pushes my texts out of sight.
Here is an example to show how it looks like:
https://dl.dropboxusercontent.com/u/11037539/unwanted_padding.png
Layout:
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/playerPane"
android:background="#color/player2">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignTop="#+id/playerName"
android:layout_alignBottom="#+id/playerStatus"
android:id="#+id/playerImage"
android:src="#drawable/ic_contact_picture"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_toRightOf="#+id/playerImage"
android:id="#+id/playerName"
android:text="Player"
android:textColor="#android:color/black"
android:singleLine="true"
android:textStyle="bold"
android:paddingTop="#dimen/player_padding"
android:paddingBottom="#dimen/player_padding"/>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="#+id/playerName"
android:layout_alignLeft="#+id/playerName"
android:id="#+id/playerStatus"
android:text="status"
android:singleLine="true"
android:paddingBottom="#dimen/player_padding" />
</RelativeLayout>
I've tried all ImageView.scaleTypes, but so far nothing works..
Thanks a lot for your help!
You just need to define your width. It should fix it. So change this line
to something like:
<ImageView
android:layout_width="75dp" //OR WHATEVER LOOKS BEST
ScaleType is only really useful when the imageview's size is smaller than the image. As previously mentioned, set the size and then you can use the scaleType to fix how the image should be scaled within the now smaller area.
i have an imageView on screen and i want to put another imageview that will appear in the bottom of the imageView (It is just like a little line), i align the line with the main imageView the problem is that it left a little margin between the main imageView and the line,
In the emulator it align perfect but in the device it let a little margin like paddingbottom and i dont know why
this is the screen
http://s2.subirimagenes.com/otros/previo/thump_8473957photoscreen.jpg
The white zone with the text "Manolo" should be on the bottom but there is a little margin
And there is the Code(is all in a linearLayout vertical)
<ImageView
android:id="#+id/imageView1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_above="#+id/inferior"
android:layout_below="#+id/superior"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:scaleType="fitXY"
android:src="#drawable/ic_launcher" />
<ImageView
android:id="#+id/imageView4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBaseline="#id/imageView1"
android:layout_alignBottom="#+id/imageView1"
android:layout_centerHorizontal="true"
android:paddingLeft="10dp"
android:paddingRight="10dp"
android:src="#drawable/fondonombretransparencia" />
Try using the 'adjustViewBounds' parameter as stated in here:
<ImageView
(...)
android:adjustViewBounds="true" />
If set to true, the ImageView will adjust its bounds to preserve the aspect ratio of its drawable. This might solve the padding difference between your emulator and the physical device.
