View 4 Replies View RelatedThere are the following layout options to create interfaces for android.
AbsoluteLayout
FrameLayout
LinearLayout
TableLayout
RelativeLayout (and some more)
Which of the following is most suitable for designing simple games? Guessing that the absoluteLayout is easiest, but will it be problems with different screen sizes? What do you recommend?
Every time I put a TextView before an EditText element in a LinearLayout, the EditText does not show. When I don't, it does.
I've narrowed the problem down to the TextView's layout_width attribute. If I give it "wrap_content", it works, but doesn't "block" down, and it appears on the same line as the EditText.

I'm getting a "SAXParseException: Unexpected end of document" error when trying to parse an xml document on android. The document in question is from the google weather api, but it seems to throw the same error regardless of the xml file in question (as long as the xml is valid) so I suspect it's a problem with my approach, rather than the xml. This is being done as a learning exercise, so I've probably (hopefully) overlooked something obvious. I've run the xml through an online validator, and it comes back as being well formed. (Can't tell me if it's valid as I don't have a DTD, but I dont think I need the DTD to parse the xml). This is the code that I'm using to try and parse the file:
private void refreshForecast() URL url;
try { url = new URL( "http://192.168.1.66:8000/google4.xml");
URLConnection connection = url.openConnection();
HttpURLConnection httpConnection = (HttpURLConnection)connection;
int responseCode = httpConnection.getResponseCode();
if (responseCode == HttpURLConnection.HTTP_OK) {
InputStream in = httpConnection.getInputStream();
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
// falls over here parsing the xml.Document dom = db.parse(in);
} } catch (ManyExceptions e) { ....
} A cutdown version of the xml that produces the error is:
<?xml version="1.0"?>
<xml_api_reply version="1">
<weather>
<forecast_information>
<city>Hamilton</city>
</forecast_information>
</weather>
</xml_api_reply>

In the interest of brevity, I've not included the original xml, but it's just the standard weather xml from googles feed. I've also tried a few completely different xml files, (including the sample from http://www.ibm.com/developerworks/xml/library/x-android/) and they all give the same error. (They also all validate as well formed when I run them through an online xml validator). This makes me think that it's not a problem with the xml, but rather with how I'm trying to feed it into the parser.

I'm registering a sensor listener with this line of code.
mSensorManager.registerListener(this,mSensorManager.getDefaultSensor (Sensor.TYPE_ACCELEROMETER), SensorManager.SENSOR_DELAY_FASTEST);
The rate is set to SENSOR_DELAY_FASTEST with the expectation that I would receive events roughly every 20-30ms. It turns out that I receive events only every 200-220ms (just now, my event code simply logcats the system time).
No matter which rate I use, SENSOR_DELAY_NORMAL, SENSOR_DELAY_UI, SENSOR_DELAY_GAME, or SENSOR_DELAY_FASTEST, I get the same result?
Got a Samsung Moment a couple of weeks ago. Last night starting using Astrid (Task/ToDo app), which came pre-installed on my phone. When I launched Astrid for the first time, I got a warning message -- something about making sure Sprint Update or Sprint Updater doesn't kill Astrid, or ruin it, or something. Clearly, I didn't understand the message. But I clicked "Okay" anyway, and started using Astrid. But I'm worried that a Sprint Update could erase all my Astrid data -- my To Do's. I'm reluctant to create many Astrid tasks until I know how to prevent them from being unexpectedly erased. My questions: Can anyone explain the situation to me? (e.g., I have no idea who/when/how/where/what Sprint updates). Can anyone explain what I need to do to prevent the catastrophe about which Astrid was warning me?

I'm currently working on a small update to a project and I'm having an issue with Relative_Layout and fill_parent in a list view. I'm trying to insert a divider between two sections in each row, much like the divider in the call log of the default dialer. I checked out the Android source code to see how they did it, but I encountered a problem when replicating their solution.
To start, here is my row item layout:
CODE:..........
The issue I'm facing is that each row has a thumbnail of varying height (ImageView01). If I set the RelativeLayout's layout_height property to fill_parent, the divider does not scale vertically to fill the row (it just remains a 1px dot). If I set layout_height to "?android:attr/listPreferredItemHeight", the divider fills the row, but the thumbnails shrink. I've done some debugging in the getView() method of the adapter, and it seems that the divider's height is not being set properly once the row has it's proper height.
Here is a portion of the getView() method:
CODE:.........
The rest of the method simply sets the appropriate text and images for the row.
Also, I create the inflater object in the adapter's constructor with: inflater = LayoutInflater.from(context);
Am I missing something essential? Or does fill_parent just not work with dynamic heights?
I have faced with issue about startActivityForResult() and onActivityResult(). If child activity started by the startActivityForResult() exit by unexpected exception the onActivityResult() is not called and I have no any ideas how can I handle this to get application working in a fail-safe manner ?
When my code runs child activity with startActivityForResult() it awaits until onActivityResult() will be invoked to get working further, but onActivityResult() is not calling and my code is "hang- up" (logically).
So the question is how can I handle all possible ways the child activity is finished (normally and by unexpected exception) to get fail-safe code ?
I have check the documentation for this issue but have found nothing relating issue.
I've been implementing a logcat reader in java which uses the binary output of logcat (-B switch) rather than the text based formats. My code works for many of the entries, but frequently the binary log entries have an extra byte inserted which I can't account for, making the payload the wrong size.
From looking at various bits of the c++ code for both the logcat program itself and the logging apis, the binary format seems to be:
CODE:...........
Payload section of the header is (payloadlength bytes total):
CODE:...............
This file defines the struct: http://www.google.com/codesearch/p?hl=en#2wSbThBwwIw/include/cutils/l...
The extra byte I'm seeing occours after the nanosecond timestamp and before the log priority of the payload. e.g. Here is a hex dump of one of the log entries with the phantom byte:
The byte (in this instance) is 0x1D at offset 0x14 0000:
CODE:.......
The extra byte shifts the payload by 1, so the payload length becomes incorrect. I can't see where this byte is coming from.
I also tried the LogReceiver class in ddmlib, but that also fails to handle extra byte and produces garbage after it hits an entry with the extra byte: [url]
Here is a quick python script which demonstrates the problem. It reads and prints binary log entries in the expected format. It will raise an exception when it encounters an entry with an unexpected byte: [url]
The logcat program itself successfully reinterprets the binary format without jumping through any hoops, so I can only guess it's some kind of struct alignment artifact. Anyone encountered this or got any idea why the extra byte is appearing?
I am attempting to integrate some previous libraries that we have within my new android project.
I have made several attempts including:
Importing the code as sub-projects (that are built using the android.jar)
Importing the code as jar files (from the built code)
Adding the files directly as part of my project
Reordering the dependencies
However for each one of these scenarios I keep getting the following exception thrown by the davlik compiler.
It is always picking the first class in the package (ie if I remove that class, it picks the next and so on).
It would appear to me that this is a compiler bug - somehow it's getting it's dependencies in a twist.
Anyone else experienced this? And/or have any ideas on how to get around this one?

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(R.string.author))
but I would like to do it in XML directly. Can anyone suggest me a way to do it?

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.
I am getting a parsing error and I do not know why (I am new to programing). Because of this error, R.java disappears and I end up having more errors. Hopefully someone can help me out. Here is where the error comes from: list.xml. Code...

View 2 Replies View RelatedI'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(R.id.webview);
wv.loadUrl("http://www.example.com/android/symptom");
wv.setInitialScale(50);
I also tried switching the order of the function calls but I get the same result¦i.e.,
WebView wv = (WebView)findViewById(R.id.webview); wv.setInitialScale(50); wv.loadUrl("http://www.example.com/android/symptom");
As an alternative, I have tried to use the "zoomOut()" function like this:
WebView wv = (WebView)findViewById(R.id.webview);
wv.loadUrl("http://www.example.com/android/symptom"); wv.zoomOut();
This approach works for a split second, and then the image reverts to its original size.
