Android :: How To Use Resource Within A Custom Xml Resource File?
Aug 3, 2010
I have an XML resource file:
<resources> <section>
<category value="1" resourceId="@xml/categoryData1" />
<category value="2" resourceId="@xml/categoryData2" />
<category value="3" resourceId="@xml/categoryData3" />
</section> </resources>
Using XmlPullParser, on the START_TAG, I can use:
int value = parser.getAttributeIntValue(null, "value", 0);
to get values 1, 2, 3...however:
int resourceId = parser.getAttributeIntValue(null, "resourceId", 0);
doesn't work...it just yields the default value 0, or whatever I change the default value (3rd parameter) to be. Does anyone know what I am doing wrong or if this is possible?

I have created a custom list item layout just like in this article http://developer.android.com/resources/articles/layout-tricks-efficie....
Each list item has icon, title and summary.
I would like to declare an xml resource that would provide data for that list. Just like you use <string-array> to populate the list using ArrayAdapter<String>.
The simple ArrayAdapter<String> can be populated from:
CODE:..........
I need each <item> to have icon, title and summary. Somewhat similar to:
CODE:..........
I would use <menu> but menu doesn't have summary if I'm not mistaken.

All of the android examples for XmlPullParser pull from a local resource file, and all of the SAX examples pull the XML from a URL. I've been told SAX is faster, so I'm trying to use that to pull data from a local resource file (res/xml/thefile.xml)
The example code I'm working off of is here. So in that example, the code I want to change is:
URL url = new URL("http://example.com/example.xml");
...
xr.parse(new InputSource(url.openStream()));
Instead of using URL, I want to use getXml(R.xml.thefile)
Is that possible, or does SAX need to get data from a URL?

the Android phones in Slovakia have a custom locale - en_SK and cs_SK. Language is either Czech or English, location is Slovakia. Now I would like to have strings that target these locales. The default approach is to create a folder "values-CountryCode", for Czech Republic it's values-cs.
But I get a build error if I add a folder name values-en_SK or values-cs_SK: "invalid resource directory name"

I'm going through an Android tutorial and I'm trying to access a color I've defined in colors.xml
<color name = "my_background">#3500ffff</color>
Then I'm trying to access this color by name:
Paint background = new Paint();
background.setColor(getResources().getColor(R.color.my_background));
but it doesn't recognize my_background as a resource. If I let the suggestions come up, only a bunch of pre-defined colors pop up that are unrelated. Any ideas? It doesn't make sense for me, I see almost the exact same thing from the developer documentation and another site, but it doesn't work for me.

I'm interested in instantiating a LinearLayout object from an xml file that has a LinearLayout file configuration. I want to do this within a method of my Activity. I tried findViewById() but that returned null. I've made sure that the LinearLayout id is the one I'm passing. Note that this layout isn't part of my screen, it's stand-alone, so I want to build a LinearLayout object from the xml.

I have a problem setting a ringtone from a resource in my app:
Uri uri = Uri.parse("android.resource://com.package.app/" + R.raw.sound1); RingtoneManager.setActualDefaultRingtoneUri(this, RingtoneManager.TYPE_RINGTONE, uri);
I've noticed also some people had the same problem but got no answers. Do any of you guys have any idea of how making this work? (without having to copy the file to the sdcard)

I am trying to read a file "words.txt" from a resource. It is a very simple, but large (2 MB), text file that I want to read line by line. I have put the file into /res/raw/words.txt, and try to open it with the following code:
CODE:...................
However, I get a java.io.IOException. This is not a "resource not found" exception, so the resource is opened correctly, but the readLine() produces the error.
I tried using the InputStream itself, with the result that read() produces -1, which stands for EOF, as if the file was empty.

I have a text file added as a raw resource. The text file contains text like:
a) IF APPLICABLE LAW REQUIRES ANY WARRANTIES WITH RESPECT TO THE SOFTWARE, ALL SUCH WARRANTIES ARE LIMITED IN DURATION TO NINETY (90) DAYS FROM THE DATE OF DELIVERY.
b) NO ORAL OR WRITTEN INFORMATION OR ADVICE GIVEN BY VIRTUAL ORIENTEERING, ITS DEALERS, DISTRIBUTORS, AGENTS OR EMPLOYEES SHALL CREATE A WARRANTY OR IN ANY WAY INCREASE THE SCOPE OF ANY WARRANTY PROVIDED HEREIN.
c) (USA only) SOME STATES DO NOT ALLOW THE EXCLUSION OF IMPLIED WARRANTIES, SO THE ABOVE EXCLUSION MAY
NOT APPLY TO YOU. THIS WARRANTY GIVES YOU SPECIFIC LEGAL RIGHTS AND YOU MAY ALSO HAVE OTHER LEGAL RIGHTS THAT VARY FROM STATE TO STATE.
On my screen I have a layout like this:
CODE:........
The code to read the raw resource is:
CODE:....
The text get's showed but after each line I get a strange character [] How can I remove that character ? I think it's New Line.

I am trying to get a video to pop up and play. I can get it to work when I use the first uri (that is commented out in the below code), but when I try to use the second uri (from the resource), I get the following error:
CODE:..........
From researching the error, it looks like I might have to declare an activity in the manifest but I'm not sure if that applies here?? Can someone point me in the right direction?

I generated a new android project in eclipse. I then copied all the files from chapter 3 in my book over to the project. After doing so the R.anything is not available and the resource file is missing. I try to clean the project and generate it but it isn't working. What I can do to fix this error?

I use this method couples of occasion to load text file to display as help file. But I don't know why the following code didn't work. It seems to hang and logcat says "OutOfMemoryError"? All I did was break this out as an separate activity.
---xml---
<?xml version="1.0" encoding="utf-8"?> <ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/helptab"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<TextView android:id="@+id/helptext"
android:layout_width="fill_parent"
android:layout_height="wrap_content" />
</ScrollView>
---code---
import java.io.DataInputStream;
import java.io.IOException; import java.io.InputStream;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class Help extends Activity {
/** Called when the activity is first created. */
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.help);
InputStream iFile = getResources().openRawResource(R.raw.help);
try { TextView helpText = (TextView) findViewById(R.id.helptext);
String strFile = inputStreamToString(iFile);
helpText.setText(strFile);
} catch (Exception e) {
} }
public String inputStreamToString(InputStream is) throws IOException {
StringBuffer sBuffer = new StringBuffer();
DataInputStream dataIO = new DataInputStream(is);
String strLine = "";
while ((strLine = dataIO.readLine()) != "") {
sBuffer.append(strLine + " ");
} dataIO.close();
is.close();
return sBuffer.toString();
}

I'm trying to unbundle a binary file (sound1.ogg) and store it on the sdcard.So it starts out as a raw resource (R.raw.sound1) and should end up as a copy named /sdcard/ mydir/sound1.ogg I wrote a method called something like copyResourceToFile() and did a copy via file descriptors / streams. But the target file just isn't right.If I do a buffered read, the target file ends up being WAY bigger - like 10x bigger.If I just do a byte-by-byte read for the size of the original file, the target file is the right size but is not the same file. Is there a simpler (well, correct/working) way to do this thing?

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').

When I make a new android project and I go to res/values/string.xml I get a screen to add android resources instead of a XML document. I keeps getting the error about : java.lang.NullPointerException.
Is there a way to just alter a XML file (like suggested in tutorials)?

Again and again I have the case that during development, the Android SDK suddenly doesn't regenerate the "R" file. Usually this is due to some error in one of the many .xml files, but that darn thing doesn't give the slighted indication, as to WHY it suddenly refuses to regenerate that file. There is no error or warning listed for any of my .xml files and manually checking all those (meanwhile almost hundred!) XML files for errors is no real fun, either! Is there some option or log or something that would allow to locate the problem quicker and more direct? Last time I had to do a lengthy binary search (i.e. copying and removing files to/from a second test project) trying to locate the offending file. That's really a nightmare and not how it should be in any decent SDK that deserves that name!

I am using the function decodeResource(Resources res, int id, BitmapFactory.Options opt).I am using it in the following way:
BitmapFactory.decodeResource(getResources(), R.drawable.image,opt);
My question is instead of using R.drawable.image which is an image in resdrawable folder, I want to use a image from sdcard.Is it possible? How to get the resource id of an image in the sdcard?

I do have a lot of language specific resources. There's one point in my Android apps where I do get a resource value and need to translate this value into the matching id. The value is not neccessarily in the language specific file for the current language (en/de/...). It's somewhere in there ... and it's unique.
After reading the docs and this thread "http://stackoverflow.com/questions/3476430/get-resource-id-by-passing-name-as-a-parameter-in-android" I thought that "getIdentifier(String name, String defType, String defPackage)" is the correct way to go but I can't get it to work. The result is always "0".
This code is part of an activity and I'm on Android 2.2.
Is it possible that Android doesn't take all resource files into account and searches just in the current language specific one?
For an example
CODE:....
To make things clear. I don't want to mis-use string resources as a database. It's only one part that occurs on very rare situations.

I will admit - I've never had a smart phone. Never. I was going to get one last year, but waited b/c I heard 2010 was 'the year of the smart phone' - and I'm glad I waited.Though I'd have to see it in person to know for sure, but I'm almost positive that DroidX will be my first smartphone. I'm VERY excited, but I want to make sure that I'm educated enough to use it for all it's worth (ie: my mom has had every iphone, but just leared to text message last month).Is there some place/book/thread/site that I can study which would tell me about smartphones from the very most basic all the way to the more advanced? I'm a smart girl, but I have to start somewhere!

If I am not wrong with the way android:sharedUserId is intended to work, then my question is how to avoid overlapping resource IDs? appt seems to aways start IDs at the same initial value (i.e. drawables at 0x7f020000), so there will be sort of conflict or ambiguation. As for now I failed to get that cleared w/o digging in OS sources. Or I miss anything, like magic "undocumented" appt option (not that aapt is documented at all)?

My application has resource conflict problem. Did some investigation, seems like all the resources within the apk file are cached after they are loaded on demand. The cache is stored in Resources.java mDrawableCache. The key to retrieve the drawable from this cache is combining the data and assertCookie fields of TypedValue class. In my application, there are 2 resources, ex. a color background and image drawable, evaluated to the SAME key value.. So just wondering, how can it happen?BTW, I am using eclair SDK.

Is it possible that a resource id (such as a generated id for a string resource) can be a negative int?Often, when defining a method that accepts a resource id, I want the caller to be able to specify a "null" value.For primitives this is not possible, but I'm wondering whether "any negative value" may be a good approach? Alternatively I suppose it would be OK to specify the argument as an Integer and take advantage of auto-boxing.Thoughts?
