I want to create an Android ImageButton in the xml file with a background image, and a smaller icon on top of that, right in the center. For some reason, it's not obvious how to do it, and documentation is no help.code...
However, no matter what I try (putting "wrap _ content" instead of absolute numbers on layout _ height and layout _ width, the icon remains in the top left corner of the button. If, however, I have no background image (i.e. a system default white button), the icon does go into the center. The button also goes into the top left corner when I use a color instead of an image for the background.
Why does this happen, and how would I actually get the behavior I want-- that is, a background image with the icon in the center?
I have a widget on my home screen with several ImageButtons which have default background images. Through the configuration activity, I can change the image on any of the ImageButtons. The problem is that when the screen is rotated, the image on the ImageButton disapears and it changes back to the default image.
I don't know why this happens or how to fix it

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.
I want to set image dynamically on the ImageButton in android. However, i have more than 200 images. what would be the good solution for that?
The best idea is that i can use the name of image to call different images. i.e. imagebutton.setImage("/res/abc.png");
however, it seems to me that it is not trivial to do so..
I'm porting an application from iPhone to Android. The iPhone app has artwork for some dozen or more buttons in their normal and pressed state. That translated over just fine to Android. However, we of course currently don't have any images for the "focused" state.
Besides the work involved in creating all these focused button images, we're not sure exactly what color to set the focus too. Selection color varies from phone to phone, etc. We'd have to come up with some neutral "white glow" of some sort I suppose. Then the idea struck -- could we programmatically render a focus images for the buttons based on the current selection color? Have folks been doing anything like this in the Android dev community? Can you point me to some examples. A net search didn't turn up anything too useful, though perhaps I searched on the wrong keywords.
I've set the background image of a custom ImageButton I am building, as well as setClickable(true) and setFocusable(true). The button is able to receive focus when I navigate with DPad/arrow keys in the emulator, however, it does not flash orange when it has the focus. It does not appear to change at all when it has the focus, in fact. When I remove the background image, however, the ImageButtons hold orange when they have focus.
What do I need to do to be enable an ImageButton with a custom background image to flash orange when it has focus?
I'm trying to make it so that as long as a user is touching the button, it shows one image, and when the user releases the button, it goes back to a default image.
I'm trying to use a selector to make this happen:
CODE:...............
I've tried a few things with the selector, but it always produces the same behavior: the button starts out with the default image, then I press it and it changes to the "record_on" image and it never goes back to the default image when I let go.
Is there a way to get this kind of behavior with an ImageButton, or should I be using something different?
I am currently trying to customize ImageButton to show different draweables as background of the Button while keeping the image set via the src attribute.

Is there a way I can find what resource a particular ImageButton is set to, at any given time?

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).

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.
Wanted to leave a ImageButton is disabled (not clickable), but have used android: enabled = "false" but does not work

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.
I have problem with width of ImageButtons, it isn't the same size. I have experimented with all attributes for two hours and nothing. I create buttons at runtime and put inside row (also created at runtime).

Here is my code:

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?
