I was wondering if it is possible to use a similar approach to change the style attribute of an element using the same (or similar) technique.Or, if that is not possible, how can the style attribute be changed during runtime (there is no such thing as button.setStyle(R.style.button)).

I created button with some shadow using a style:
<style name="test">
<item name="android:shadowColor">#FFFFFF</item>
<item name="android:shadowRadius">1</item>
<item name="android:shadowDx">1</item>
<item name="android:shadowDy">1</item>
</style>
This applies a white shadow on the button's text in its normal state. I was just wondering if anyone knows if there is a way to remove this shadow when the button is a pressed state. In other words, is there a way to apply another style when the button is in another (pressed) state?
I'm creating my own View class, and defining custom xml attributes with a attrs.xml. As long as I provide each attribute manually, there is no problem, but
code:...................
The android:text is properly set in my instance, but the borderDrawable is not. I guess this has something to do with namespaces, because inside the styles.xml, the name="mypack:borderDrawable" is not handled by the XML parser's namespace facility, because its inside an attribute value. So "mypack" is in no way connected to "http://some.weird.url.com/seems/not/to/ matter" and adding it via xmlns:mypack... to the stylefile would not help, I guess. In the same file, "android:text" is somehow recognized, even though "android" is AFAIK only a ns-defintion for [url], which is also not declared in that file.
So what is the proper way to set a custom attribute in a style?
I finally decided to use styles and themes instead of tediously setting attributes for each individual view. I was able to get the style to work when I set it on android:textAppearance, but when I try to just set it right on the style attribute like below, it no longer applies.This is happening to me for Buttons as well as TextViews. What I want is to be able to have a few different styles for text views and buttons and then just set the style on each button or text view.The style will need to define textSize, textColor, background and maybe a few others.Since background and some other things are not textAppearance,I need to use the general style attribute.
View 4 Replies View RelatedThis question is about setting the "style" attribute programmatically, but it needs a bit of background first. I wish to create a custom component which will looks like a EditText box but not actually allow direct input. (When focused or touched it will pop up a dialog to allow data to be entered).

View 1 Replies View RelatedI 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?

Im trying to figure out how to use Styles. It seems easy, but its not working.
First, here is my XML for the Button:
<Button style="@style/Btest" android:id="@+id/Button01" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Some text"></Button>
And here is the values/styles.xml:

Its not working at all. If I dont use Style and just add the style directly in the XML for the Button - no problem.

View 4 Replies View RelatedHow to set style(small and large) to Button programmable way ?
Is it possible ?
I can set the style to the Button from xml resource (like styte= ?android:attr/buttonStyleSmall).
But I don't know how set it programmable way.
I am trying to get the button in my layout to have focus as I am programmatically changing its state. My application is a video player using VideoView. I am toggling the state of the button based on where my video is. So basically, I am doing videoview.getCurrentPosition() and if it is in a certain window, I want to toggle my Button state (enabled to disabled and vice versa). The layout is LinearLayout and I have the VideoView and Button layed horizontally. When I first had the MediaController in my Video, the button would change focus on touching the videoview (which is when the MediaController would pop up). I later removed the controller because I didn't want the button state to change when the user touches the screen. I want it to change automatically.
I tried all sorts of combinations possible. button.setFocusable(), button.requestFocus(), button.bringToFront() and so on. But none of them seem to work.
Is there any way I can make it toggle programatically and without user intervention through touch? or is it impossible to do it with the VideoView?
I am trying to toggle button state programatically. I want to go between setEnabled(False) and setEnabled(True) for a given duration. I have a timer and I want to toggle between these states at regular time intervals.
I see that the button toggles correctly the first time, for e.g. from True state to False state, but doesn't go back to True state again unless I touch the button, which is kinda weird.
I have an image button as defined below.

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 new to Android and just starting the very basics. I implement my custom button skin using .9.png images for norma/focus/pressed states. It works fine, but I noticed that after a pressed the focussed button it visually "lost" focus and draws the normal state frame. I planned to use different state images to highloght what button is selected right now, but it seems that it would not work. I noticed also that the same happens with the default LAF button. Is it OK, or it's just emulator issue? What the good workaroud can be used?
View 2 Replies View RelatedI am having an issue related to home key . when i press home key all current activity gets hidden. but when i press the executable it again starts from the fisrt screen . I have overidden all methods nsaveInstaceState opPause onStop onResume
but there are still issues what is the right way to handle those conditions. When i am pressing home button i am storing the widgets state in database and when i again click the exectable i am checking the database state and starting the new Intent as saved when user presses the home button .Is it the right way to do that as i am facing the problem when user does the same and again presses the back button , there is already on intent available in stack of activity .
I am working on my App. in between i pressed the Home button on the device. my app will go to the background tasks. After that i long press the home button it will show my app as a persistent state. i.e where and what i had done in my app. But i click my app in the directory window it restarts my app. i want to do if my app is in the background tasks it will wake up else it will start. how to achieve that?
View 1 Replies View RelatedWhenever I press the home button when Im in the root task of my application and when I click on the icon of my app again the state of my task (activity) is retained, but when i press the back button on the emulator and when I open my application its state is not retained. I want the state to be retained in both the scenarios.
In the mnifest I have given the below entries,
android:alwaysRetainTaskState="true" for the root activity
android:launchMode="singleTask" for the application
I have noticed while working in the emulator that whenever i get out of my app via any method other than pressing the back button, my toggle button (if pressed) will have its state saved and return to that state when i return to the app. im guessing its because its value gets saved in a bundle and reloaded when i return. when i leave the app via the back button, this does not happen and the toggle is always off when i return. is there any way to get the value of the toggle back if the user leaves via the back button, without having to save the value in a db table? alternatively, if my apps notification is in the status bar, i can be confident that the toggle should always be selected, so if there is no way to save the state, is there a way to find out if my apps notification is currently being displayed? then it would be easy to just set the toggle each time via a quick check of the status bar.
View 1 Replies View RelatedI am using a <Button> widget in one of my layout. I created this button in disabled state. A thin white line runs through the button, at center horizontal, while it is in disabled state. And in enabled state it is normal like any other widgets.

I tried to re-implement what HTC did with the One X, One S, etc, where they have physical back, home, recent apps keys, and a virtual menu button pops up under apps that need a menu button. I don't have an Android device, so I was only able to test it under the emulator, I have only tested it with the Facebook app, but it seems to work fine.
The patch is against AOSP 4.1.1, to activate it in the emulator, set hw.mainKeys=yes and hw.menuButton=no in hardware.ini. For a real device, you'd need to set config_showNavigationBar to false and config_showLegacyMenuButton to true.
Because this is just a proof of concept, it pops up the entire ICS navigation bar with all four buttons instead of just the menu button. But that's not hard to fix.
I have an Activity with a list that is bound to a ListAdapter reading data into a ArrayList from a database. All is well when the data is first loaded. While the Activity is open and the list is being displayed it is possible and likely that the data in the database will be updated by a service but the list does not reflect the changes because the ArrayList does not know about the changes. If the Activity is no longer in the foreground as would be the case if the user goes to the home screen and then is brought back to the foreground I would like for the Activity to not display what it did prior but rather reload the data using the ListAdapter the view is bound to. I think something needs to call finish() but I am not sure what.
This is what I have in the Activity.

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?
