If 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.

I have a gallery that displays TextViews where the background of each view is the following code...
This selector work just fine for the state_pressed and default (idle) states, but the selected item state is never displayed. I REALLY do not want to force the background of the selected item by changing the background of the view when the onItemSelected event is called. What is the correct state or correct way to get the TextView background to be set properly. Is the selected (center) view in the gallery not really selected? Is there some other state I should put in the selector drawable xml?
In my android app, I have a preferenceScreen with some checkboxes defined in a xml file and a class that implements "SharedPreferences.OnSharedPreferenceChangeListener". What I want to do is to select a checkbox and all the others to be selected as well. In the above listener I am able to modify the other checkboxes's state to selected, but my view remains unchanged. What should/could I do to achieve this ?

Also, when the content of the WebView is selected, scrolling down with the track back does not seem to cause the WebView to loose focus. If I continue to scroll down with the track ball, all of a sudden an item in the middle of the ListView gets selected.
I am trying to remove an ImageButton's background in only the default state. I'd like the pressed and selected states to behave as usual so that they look correct on different devices, which use different colors for the pressed and selected states.
Is there any way to set an ImageButton's background default state's drawable without affecting the pressed and selected states?
I've tried to do this with a selector, but it does not appear to allow you to use the default drawables for some states - you have to set all the states yourself. Since there's no API to retrieve the device's default pressed/selected drawables, I don't know what to set the pressed/selected states to.
I also tried getting the StateListDrawable object for the button that the system creates when you are not using a selector and then modify it change the default state. That didn't work either.
I seems that on Android, if you want to change the drawable for one state of a button, then you must set all the states, and thus cannot preserve the default drawables for the other states. Is this correct?
I have a compound UI component built up from a ViewGroup containing a number of TextView, ImageView etc. components. Many of these have StateListDrawables as their images/backgrounds. Is there any way of making them select from this drawable based on the state of the parent ViewGroup rather than the component itself? Ideally I want to be able to change the visual state of all children of the ViewGroup (text colour, image etc) based on the state of the ViewGroup, preferably without having to hook up complex logical code. This seems like a fairly common sort of requirement, so I was hoping it would be straightforward in Android - am I going to be disappointed?
View 1 Replies View RelatedI'm a little confused by what I'm seeing with regards to phone state transitions via the PhoneStateListener. When I receive a call, this is what happens: (call comes in) RINGING -> IDLE (I pick up) OFFHOOK (I hang up) IDLE It's that first transition from RINGING to IDLE without any interaction from me (not ending the call, not answering the call) that confuses me. Do I really have to implement an idle counter to know that an incoming call has really ended? Seems like the reported phone state represents some sort of phone state that isn't the obvious one.Is this a bug or am I just not in tune with the paradigm here?

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 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).

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.

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.
