Android :: Get Line Number An Xml Element Is On Via Java W3c Dom Api?

Apr 30, 2010

Is there a way to lookup the line number that a given element is at in an xml file via the w3c dom api?

My use case for this is that we have 30,000+ maps in kml/xml format. I wrote a unit test that iterates over each file found on the hard drive (about 17GB worth) and tests that it is parseable by our application. When it fails I throw an exception that contains the element instance that was considered "invalid". In order for our mapping department (nobody here knows how to program) to easily track down the typo we would like to log the line number of the element that caused the exception.

Can anybody suggest a way to do this? Please note we are using the W3C dom api included in the Android 1.6 SDK.

Android :: Parse Exception3- At Line 1 Column 0 - No Element Found

Apr 26, 2010

I have a weird issue. I receive the following error that causes a force-close:


After clicking the Force Close button, the Activity is recreated and the parsing completes without a hitch. I'm using the following code snippet inside doInBackground of an AsyncTask:


Why would the Activity force-close and then run without any problems immediately after? Would a BufferedInputStream be any different? I'm baffled.

It turns out HttpURLConnection.getResponseCode() returns -1 every so often, so the InputStream probably isn't being correctly set.

Android :: R Java File Not Updating With UI Element's Id

Mar 21, 2010

I added some UI elements to the main.xml file in the reslayout folder and when I try to access them through the call, R . layout. my _ uielement, the UI element that I created is not there. Even when I add a new xml file with UI elements, it still doesn't show up in the R.layout class. I have made checked the ids on them and they have the correct format (I think): android:id="@+id/my_button". What could be the problem? Do I need to compile the code first? UPDATE: I have already tried adb kill-server then adb start-server. It doesn't seem to help. I have also tried, it doesn't register either.

Android :: Inject A <string> Element Into Another In XML?

Sep 15, 2010

I would like to know whether there is a way to insert/inject a <string> element defined in an XML file into another <string> element, doing that just with XML.

For example I could have:

<string name="author">Francesco</string>`

and I am looking for something like:

<string name="about_application">Author: @string/author</string>`

so that getString(R.string.about_application) would result in "Author: Francesco".

I know that I could combine the two elements in Java code using String.format(string, formatArgs)like for example:

<string name="author">Francesco</string>
<string name="about_application">Author: %1$s</string>`

and then in code use

String.format(getString(R.string.about_application), getString(

but I would like to do it in XML directly. Can anyone suggest me a way to do it?

Android :: Updating Single ListView Element?

Mar 29, 2010

In the application I am working on now I came up with the following problem. I have list view which is displaying items with images in most cases it will be different image for different items (thumbnails about 60x60 pixels). So the problem is how can I handle image processing for the view. For know I have the following variants:

1. I can cache all bitmaps and when I try to display view I get bitmap from cache synchronously and display it. The problem is that 60x60=3600x4=14kb per bitmap which is waste of resources.

2. When I need to display view I can register event to some thread to decode the associated bitmap which will decode it in background and than to update gui. This sounds good for me the scrolling is still smooth because all image processing is done in background. Updating list view is bit jerky for now I am doing it view notifyDataSetChanged which is updating all visible views although I can update thumbnail for a single item.

So question one is is there better way the update single listview element than calling notifyDataSetChanged.

Android :: Scaling Web Page In WebView Element

Nov 30, 2009

I'm loading a URL into a WebView and I'm having difficulty setting the "scale" of the web-page. Specifically, the web-page is too big (800x600) for the screen, so my thought is to use "setInitialScale(50)" to reduce the size. Here is some sample code that doesn't work (i.e. the web-page doesn't scale to 50%)

WebView wv = (WebView)findViewById(;
I also tried switching the order of the function calls but I get the same result¦i.e.,
WebView wv = (WebView)findViewById(; wv.setInitialScale(50); wv.loadUrl("");

As an alternative, I have tried to use the "zoomOut()" function like this:
WebView wv = (WebView)findViewById(;
wv.loadUrl(""); wv.zoomOut();
This approach works for a split second, and then the image reverts to its original size.

Here is my content view:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android=" android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent"> <WebView android:id="@+id/webview"
android:layout_width="fill_parent" android:layout_height="fill_parent" /> </LinearLayout>

Android :: How To Change Tab By Clicking On Element INSIDE Tab?

Can someone please tell me how to change tab by clicking on element INSIDE the tab? I already tried it with global data.

Now when I'm trying to change tab in my ListActivity tab by clicking on one of the items it doesn't do anything and stays on the ListActivity tab. Perhaps I shouldn't use onResume() here. Basically I want to go to first tab when I click on one of the items in the list. Please help!

Android :: How To Know Which Element Of List Is Selected When Long Click

Jan 22, 2009

I have a list using a customized BaseAdapter. When one element of the list is hit during a long time, a contextual menu appears. I want to use this one to delete or edit the selected item but I don't know how to get id or anything else that could help me.

I tried getListView.getSelectedItem() thinking that it will give me the object returned by the method getItem(int position) inherited in my customized BaseAdapter. I got null. When I tried getSelectedItemId(), I got -1.

Does someone have a solution?

Android :: FindViewByID - Get View Of A TextView Through A Listener Of Another UI Element?

Sep 9, 2010

This is going to be a bit lame question. I have the following code:


I have a TextView in my xml layout file. I'd like to get it and change my text when I click this button.
But I can't get it (the TextView) unless I make it as a value of a static member of this class and pass it to the constructor. I believe I am missing a big point here, so i'd be very thankful if you could explain how this is meant to be done ?

Android :: PreferenceScreen - Intent - Element Throws Exception

Sep 17, 2010

I've got a probleme with an exception, but I don't know why I get this exception.

The project is about implementing an AbstractAccountAuthenticator with an AbstractThreadedSyncAdapter to sync certain data on a server with a content provider.

I made everything and both adding accounts and syncing is running without any problems.

Now I've tried to add a Preference-Screen just like suggested in the android reference (search for AbstractAccountAuthenticator, it is explained there) via xml like this:



The Preference-Screen-xml looks like this:


The screen is promted how it should be, but and that is the problem: When I click on the PreferenceScreen with the intent it leads to a crash of the system (both in the emulator and my HTC-Desire).

Logcat says:


Here the part of the manifest, where the activity is defined:


The whole test-code (it is my project on the essentials to find the problem) is to find at googlecode ( cleanproject/source/browse/) (Eclipse-Project)
