Android :: Getting Style Attribute To Work
Jun 3, 2009
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.

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?

This 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).

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'm very new (second day!) to android and working my way through the dev guide. There, it says that you can reference attributes inside the current theme from your XML by using the form?.If I try to build this, I just get "No resource found that matches the given name (at 'textColor' with value '?android:textDisabledColor')
Given that this seems pretty basic stuff, and yet I can't find any references to similar problems elsewhere, I must be missing something obvious or misunderstanding something simple. Can anyone tell me what it is?

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

When I include <style> elements from /res/values/styles.xml the Layout designer/preview within Eclipse doesn't update with these styles, but shows as it would be without any styles.Can anyone confirm this issue? If so, Is there a way I can fix this myself easily? If not, where's the appropriate place to sumbit a bug report?

Any View have a constructor public View (Context context, AttributeSet attrs, int defStyle) which called when View declared with a style attribute So, if I have some class inherited from View class, I can access to declared attributes (like "android:layout_width" or "android:background") via AttributeSet attrs in a constructor. But when I move attributes to style I cannot see attributes and values exists in a style - I want to read items declared in style but I have only styleID in defStyle parameter. Is there some way to read style Items using styleID?

I've developed a fairly extensive application. The problem began when I started programming...my spinners are the solid gray rectangular style (unlike the newer style with the triangle in the lower right corner). When I started developing this app several months ago, I couldn't figure out why my spinners were different (after many hours) so I just ignored it. I'm at the point now of polishing my program and want the newer spinner style. So, I'm beating my head against the wall again. I went to my Android SDK Mananger in Eclipse and updated my Android SDK Tools, Platform-tools, and Build-tools. I have the lastest versions of all of these (22.3 and 19.0.1). When I create a new project, the newer spinner style appears. However, none of my older projects changed. They still have the same old gray, rectangular type spinners. I tried using a "android format" line command I found while Googling, but no luck with that either.I'm using ADT Bundle with build v22.2.1-833290 on a Mac OSX Mavericks.

I'm trying to compile an app via Android 1.6, and got errors shown below. It said some strings in TextView and Button are not localized. I know how to fix them. It's easy to add them to strings.xml. But I still doubt why I need to localize every string. I don't think the strings like '1024' (pure number) or '80 x 25' need to be localized. Can't I set some strings to be non-localized? I searched SDK 1.6 documents, but can't find any help.

Is there an easy way to grab a attribute value from an xml item in your Java class definition?I know you can grab similar xml attributes from the converted objects using getters/setters like View.getText().I'm just wondering if there's a way to grab an xml attribute right from the item itself.

I set the tag attribute on a custom widget in my layout XML:
Code:
<com.louisvillemade.thegirlyapp.widgets.GirlySeekBar
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="40dp"
android:layout_marginRight="40dp"
android:layout_marginBottom="16dp"
android:gravity="center"
android:layout_gravity="center"
android:max="19"
android:tag="attr_2"
android:progress="0"
[code]....
How do I grab some of the XML elements, like the android:tag element (set to "attr_2") through reflection of seekBar? Calling seekBar.getTag() returns null and I can't seem to find any methods on the Drawable that will give me what I want.

I have attribute "attr1" defined for my views A, B, C. A and B are actually ViewGroups. Let's say C is contained in B and B in A. Is there an existing mechanism in Android framework that allows me to specify the value of attr1 in A and have it automatically propagated to B and C?

I've created a combo box control with a edittext and spinner. I'm trying to let the android:prompt attribute be passed onto the spinner, which means I need to catch it in the constructor which passes my the AttributeSet and set it on the spinner. I can't figure out how to get the value of the prompt.
I get back 0, which means it didn't find the attribute.I also did a ta.count() which returned 0. So I'm not getting anything back.My XML simply defines an android:prompt value.

I am using SAXParser to parse an html page (any better solution?) and have this exception:
W/System.err( 1358): org.apache.harmony.xml.ExpatParser $ParseException: At line 1, column 59: not well-formed (invalid token)
I have reduced the page to this:
<div id="submenu"><a href="/compte/console.pl? id=382730&idt=1cf6b94aa1a4cf84"></a></div>
And what causes the exception is the '&' inside the href attribute value.
Here is a minimalist test code:
DefaultHandler emptySaxHandler = new DefaultHandler() {};
String xmlstr = "<div id="submenu"><a href="/compte/console.pl?id=382730&idt=1cf6b94aa1a4cf84"></a></div>";
SAXParserFactory factory = SAXParserFactory.newInstance();
SAXParser saxParser = factory.newSAXParser();
saxParser.parse(new ByteArrayInputStream(xmlstr.getBytes ()),emptySaxHandler);
Is this a normal behaviour or kind of bug? If normal, what should do to preprocess the string before parsing?

Is there XML attribute that does the exact opposite of android:dependency? What I would like the dependent preference to be enabled when the other is not checked and disabled when it is checked. Maybe the issue isn't with android:dependency maybe there is an xml attribute that I can add to make the default for that preference disabled and then android:dependency will toggle it the opposite way like I want. I tried setting android:enabled="false" in the preference and it disables it like I want but even with it being dependent on the other preference it didn't enable it like I had hoped.

I get the following error in logcat: java.lang.RuntimeException: Binary XML file line #26: You must supply a layout_height attribute. Can you please tell me which xml file that I am missing? And it said 'binary xml', does it mean it is actually line 26 in my file? or it is line 26 in the file after it compiles to be a binary xml file?..........

It looks like the naming style for android attributes varies between underscore and camel case. Does the variation mean anything, or is it arbitrary? edit: examples would be layout_width and columnWidth.

I'm having some trouble accessing attributes like DURATION and DATE_MODIFIED of video and image. My app access these attributes for both type of data but if I take a picture or shoot a video the related attributes are not immediately available through content provider e.g. for DURATION for that specific video it returns 0.
If I restart the phone the attribute for the newly shoot video or picture taken becomes available.
The other way to make the attributes available is to plug in and out your phone to a computer through usb cable. Once that is done the attributes are available.
