I'm using the following code, which I expect would scale the associated image to fit within the given dimensions of the button:
CODE:.....
The image is 64X64 and I was expecting to see 32X32 on the screen. However, the button draws with the original 64X64 size. I can re- sample the image down and create a new file but I'm curious why this approach didn't work.

is it possible to use onKeyDown() for an ImageButton instead of onClick() to capture the user's click on this imagebutton?
View 3 Replies View RelatedHow can I have an imagebutton stay in the 'pressed' state when it is clicked? Basically I just want the background to be the depressed background, but I can't figure out how to set it. At the moment, I've just copied the selected button background into my res folder, but when I set it as the background, it becomes blurry (since the original image is bigger than the button itself).
Normal Background:
What I'm getting:
Also I don't believe I can actually use this method considering the many different UI layouts. The button should stay pressed as per the UI the user is using.

I'm having a problem when setting the visibility of two image buttons one on top of the other. The idea is to implement a play/pause control. The problem is that the only part where setting the visibility actually works is in the click listeners of the buttons. If I try to change it somewhere else nothing happens.

I'm trying to create a transparent (no button background) ImageButton that has a custom selector. I have the selector working against the button but I now want the selector drawables to cross-fade into each other.
I saw the TransitionDrawable object that can be represented in XML. Is there a way to connect this into my selector?
Below is the XML layout code to create the image button on the screen in the lower left corner of the screen. It currently goes from one image to the next abruptly ignoring the transition XML.

I have 1 imageButton and i want to hide that button after 5sec in oncreate method.

View 5 Replies View RelatedIf I was using an ImageButton with a selector for its background, is there a state I can change which will make it change its appearance? Right now I can get it to change images when pressed, but there seems to be no "highlighted" or "selected" or similar state which lets me toggle it's appearance at will.
Here's my XML, it only changes appearance when pressed.

When using the "selector" to specify different images for buttons for different states, such as pressed, focused etc, do I have to write an xml file for each button? I have about 15-20 buttons in my app, so was wondering if there is a way to write just one xml and refer to parts of it?
View 2 Replies View RelatedI want to setImageResource for an ImageButton programatically, based on a variable.
For eg: if size=5, I want to setImageResource to R.drawable.five if size=6, I want to setImageResource to R.drawable.six
Unfortunately, I have too many of these, so an if-else or switch gets tiring.
Is there a way to achieve something like: R.drawable.size?

So URL is www.site.com/images/(i++).png
A 'Button' view comes up with text, while the 'ImageButton' widget comes up with an image but no text, is there a way to relatively easily (e.g. method calls, say), either:
1. Add text to ImageButton (like those buttons that appear in menu item/via the physical menu button)?
2. Add an icon/image to a Button?
without resorting to constructing a new button class? I.e. I could put text within the image, but then I can't use Localization properly/effectively.
Is there a way I can find what resource a particular ImageButton is set to, at any given time?
For eg: I have an ImageButton that I set to R.drawable.btn_on onCreate. Later, at some point, the ImageButton gets set to R.drawable.btn_off. I want to be able to check what resource the ImageButton is set to in my code.
I want to be able to specify an android:src, but I want android:background="" - complaints that string types are not allowed when compiling.
I basically want a button without any background (but that *does* have a 'src').
I want to use an imagebutton in my application, but only a button with image can not indicate its function clearly. If there are some text beside the button, I think everything will be more explicit.
