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?

I am trying to make ImageButton for state of pressed, focused and normal.
I've read introduction of ImageButton from this: http://developer.android.com/reference/android/widget/ImageButton.html
I've saved selector XML file in /res/drawable/. Also set the android:src="@drawable/my_selector".
my_selector.xml file :
CODE:................
I think I've done correct ImageButton. But it didn't work for me.
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.
That's my custom_button.xml:
CODE:..............
I have a button with two states(selected and unselected). the image of button is different for the states. Which one should I use? How do i set images and states?

The only thing I might not have done is following. I don't know how to do that: compiled resource datatype: Resource pointer to a ColorStateList.
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'm having a bit of a problem with a custom button style. I have the button states (9-patch drawables) set up in a <selector> drawable. The style I'm going for is a button that looks like it gets pushed down, i.e., you can see the front edge of the button until you press it. It works fine for the button itself, but the contents of the Button (or ImageButton) don't move when pressed, even though I have the 9-patch areas set up to move the content area for the depressed button states. It seems like it's keeping the same 9-patch areas no matter which image it's showing.
Here's an animated GIF to help make the problem a little clearer, since I'm awful at explaining things: http://www.crappytools.net/button_problem.gif The button moves when pressed, but the icon inside stays still. I played with the Draw 9-Patch utility, and it shows that the content area in the depressed image should be shifting downwards like intended.
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?
My 1.6 app works fine in both portrait and landscape modes on the default HVGA device. I'm now trying to support it on QVGA devices and am encountering build-time errors I don't understand. In my res/drawable-ldpi directory I have:
startstopin.png startstopout.png and a selector file
startstopbuttonimageselector.xml
which contains:
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:drawable="@drawable-ldpi/startstopin" />
<!-- pressed --> <item android:drawable="@drawable-ldpi/startstopout" />
<!-- default --> </selector>
I've 'fixed project properties' and done a 'clean' build, to no avail. The error I get is:
Error: No resource found that matches the given name (at 'drawable' with value '@drawable-ldpi/startstopin').
Error: No resource found that matches the given name (at 'drawable' with value '@drawable-ldpi/startstopout').
I've tried adding a layout file in res/layout-small that explicitly references this selector file, but this triggers a similar build error and fails to address the original problem:
Error: No resource found that matches the given name (at 'src' with value '@drawable-ldpi/startstopbuttonimageselector').
selector is not working.

I have an image selector that has the "pressed" state set to a particular drawable. I want to give the user the opportunity to change this on the fly. However, I have found no way to programmatically get and modify a selector.

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
Does anyone know how to disable an ImageButton?
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).

Is it possible to add a click event to an ImageButton? In my code its not working
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 have 2 questions regarding a ListView in Android:
How can I get the color of the listview's focused row ? I tried to use the ListView.getSelector() method, which according to its documentation should give me what I'm looking for, but it's giving me a Drawable object which I don't know how to retrieve the color from (if possible...).
How can I set the color of the listview's focused row ? Here I tried to use the setSelector() method on the listview, passing it a ColorDrawable object, but the result of doing it is that the whole background of the list view is painted in that color... and this is not what I wanted of course...
I'm looking for suggestions on how to go about adding a ListView selector that is 'permanent'. By this, I mean a single row in the ListView is always highlighted; it should move up or down in reponse to any D-pad presses (i.e. like the default selector) but also remain set/highlighted if the user were to scroll the ListView in either direction (i.e. it's still highlighted even when it's off-screen).
I've looked at using the standard selector mechanism, but am unable to get the selector to remain in place if the ListView is touched (and thus scrolled), so it makes me think that this isn't the best option? Perhaps there's a <selector> "state_*" that I've ignored?
The other option would be to use the onItemSelected() callback, but at first look this appears more convoluted?
Any suggestions/recommendations/experiences gratefully received.
