I want to create say 5 different types of cells in table along with identifiers and load them appropriately as per the given data depending upon the type?
Creating TableRow inside TableLayout seems to be one of the options but how to dynamically create the tableRows depending upon the type?
Here is my screen description: It is a TableLayout and it contains multiple Rows. I have set TableRow as clickable, as I want to go to next screen on click of a tableRow. Everything I am doing through Java programming (instead of XML layout, because number of TableRows changes each time) On next screen, I wanted to display all the views of that particular clicked TableRow. Here the problem i am facing is how to capture particular tableRow on onclick() even and how do I get all the textviews of that particular Row. I tried to set id at runtime, and tried to get id of view, but it's not working, giving error resourcenotfoundexception.

I've checked logcat and it doesn't seem to report a problem...
CODE:........
I've been pouring over this and I bet its some silly syntax typo! Or, at least I hope it is something trivial.
I have a table layout with a few predefined rows in it. Each row has only two columns.
Now I need to dynamically add additional rows in it.
I have two problems:
1) When programmatically inflating, I cannot set the index of the newly created row (I want it in place 'n') 2) After inflation, the inserted (actually appended) row doesn't listen to parent table's stretch column property.
So here are my questions:
q1) Can I set the place where to insert the inflated row programatically ?
q2) Why doesn't the new row inflate properly (the second column is not shown because the first column doesn't contains a TextView with fill_parent.
In the end I need the first column to occupy 80% of the screen width, and the second column remaining 20%.
q3) is that doable with programmatic row insertions ?
When a button is clicked, the following method is run:
public void createTableRow(View v) {
TableLayout tl = (TableLayout) findViewById(R.id.spreadsheet);
TableRow tr = new TableRow(this);
LayoutParams lp = new LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT);
tr.setLayoutParams(lp);
TextView tvLeft = new TextView(this);
tvLeft.setLayoutParams(lp);......................
R.id.spreadsheet is an xml TableLayout. I can see from debugging that the method is being accessed, but nothing is drawn to the screen. What gives? Do I need to reset the Content View somehow?
I've got the following row xml file which consists of CheckboxView and TextView;
CODE:............
When the app run, i'm unable to "tick" any of the check boxes...
Check for system updates doesn't check.

I'm having trouble with something that works in the Notepad example.
Here's the code from the NotepadCodeLab/Notepadv1Solution:
CODE:.................
This code seems to work fine. But just to be clear, I ran the adb utility and run sqlite3 I inspected the schema as follows:
CODE:...............
All seems good to me.
Now on to My App, which as far as I can see is basically the same with a few minor changes. I've simplified and simplified my code, but the problem persists.
CODE:..............
When I run my app, I get a RuntimeException and the following prints in LogCat from my Log.e() statement:
LogCat Message: java.lang.IllegalArgumentException: column '_id' does not exist
So, back to sqlite3 to see what's different about my schema:
CODE:.................
I don't see how I'm missing the '_id'.
Can anyone point out what I've done wrong?
One thing that's different between my app and the Notepad example is that I started by creating my application from scratch using the Eclipse wizard while the sample app comes already put together. Is
there some sort of environmental change I need to make for a new app to use a sqlite database?

View 3 Replies View RelatedI saw on http://developer.android.com/guide/topics/security/security.html that my app can declare a permission:
.....................
However, what if com.me.app.myapp is not yet installed on the device?
[a] I tested with "adb install", and Foo was installed on the device without incident. The only thing I see is "W/PackageManager( 62): Unknown permission com.me.app.myapp.permission.DEADLY_ACTIVITY in package com.foo.Foo"
[b] if I upload Foo into Android Market, but the user has not yet installed "myapp", will he be able to see Foo in market?
[c] if the answer to [b] is yes (I really hope so, or else it will be a major bummer ...) what message will the user see regarding com.me.app.myapp.permission.DEADLY_ACTIVITY? Since the description of this permission is declared only in "myapp", without "myapp" installed, will the user just see the name of the permission, which probably doesn't mean much?
If [c] is true, would this be a weakness to the Android permission system/Android Market? As long as I can fool the user to install my app first, I would be able to gain permissions that the user would not have otherwise granted me (had he known the true nature of such permissions).
I already have a home replacement app (tried out a few and settled on ADWlauncher for the time being.) I'm wondering if there's an app that (in a similar way to a home replacement) would replace the actual calls function of the phone, I find the 'slide to answer' very annoying as I often miss it - and navigating the call log and contacts list from within the default phone app is very annoying. Is there anything like that? Also is it possible to change the colour of the notification bar? I'd prefer if it was dark blue (or at least a darker colour) to fit in with the theme for the rest of my phone. (On the Moto Milestone 2.1 if this makes any difference)
View 3 Replies View RelatedCurrently I use the desktop app quicken to track all my expenses. More and more I'm relying on my android phone to do my daily tasks. I have been searching and reading for weeks now trying to find an app that suits my needs and so far I haven't come up with what I need. Many come close but so far none can provide all three of my requirements. So, does any one of you l33t android users know of an app that can meet these three requirements?
(1) Must be stand alone - If it can sync with a desktop app like quicken for example, that's great but it shouldn't rely on that to function.
(2) Supports downloading bank data directly - My bank (USAA) supports just about every connection method. Every app I have tried for every phone that has this feature has been able to connect to USAA and retrieve my transactions without issue. Downloading to a file and importing manually is not an option.
(3) Must support recurring / scheduled transactions - I want to be able to plug in my monthly recurring bills and have some way of viewing my future balance as the bills hit. Quicken does this with a bar graph and a calender. Either one would work. The biggie (Mint.com) is great but doesn't support the third requirement even though hundreds of people have posted, asking for this feature (guess no one is listening or acting on it). Quicken doesn't have a mobile app. Splash money doesn't have an Android version. Ascendo Money doesn't have an android version. Seems like everything I have found is 2 out of 3.. I don't see how my list of 3 is asking that much?
I have a sqlite database, and i put this file in "assets" folder. The code like below, Pls help and tell what's wrong in this code, How to use my own sqlite database.
CODE:.............
The error message:
CODE:.................
Menu - Settings - Location - Enable GPS satellites
It states that enabling this will "require more battery plus view of sky"
When checked, it states "deselect to conserve battery"
So, the question is, should this be enabled?
I imagine for some applications, knowing your precise location should be useful, especially if the turn-by-turn maps are installed and used.
I'm thinking to deselect this, and selecting it at times when I need it.
So, to check or not to check?
A couple of months ago I decided to jump on the Android bandwagon, starting with the Incredible then moving on to the Evo. Everything was going well, life was good, then Apple announces the iPhone 4! I watched the keynote in total awe and drooled when Jon I've explained how glorious the "new" iPhone was and how it will "change everything again." Then the dust settled. The iPhone 4 will be a great phone, however it doesn't offer anything new to me. Virtually all of the reasons I used to justify switching to Android still exist!
My take on the iPhone 4:
Excellent build quality (HTC should take notes)
Fantastic screen
Up to 32 Gig memory
Integrated Video Chat/Conferencing (Wifi Only)
Very thin
It's purdy
Pseudo multitasking
Glass back
For $25 month you can get 2Gig xfer
Here's why I STILL prefer the EVO on Sprint:
WiFi Mobile Hotspot (Saves me $30 per month over my Verizon MIFI)
WiFi Mobile Hotspot allows me to hop on my laptop or my 6 year old to stream Netflix on the iPad!
Sprint TV
Unlimited data baby!
4G
Text to Speech
Speech to Text
HDMI out
8 Megapixel w/dual Flash
Replaceable battery
Turn by turn directions
Voice search
I can VPN to my work computer
3G coverage! I paid $30 per month for Edge on the iPhone! Sprint offers 3G!
Ability to video chat over 3G/4G (Been using Fring)
Ability to transfer files via FTP to my host account
I can select an app to install without being kicked out of the Market!
I have the ability to create ringtones on the fly. No need to pay an additional fee to iTunes to "convert" a song.
Live wallpapers!
Built in radio
I've found the Amazon MP3 store to be much cheaper than iTunes. For example, Fray's "The Fray" is $9.99 on itunes vs. $5.00 on Amazon MP3!
Flash Lite
I can rotate my photos
I can expand my memory
Sprints plans are cheap as hell compared to AT&T
I can email photos at full resolution
How many times have iPhone users purchased an app, only to be disappointed? On the Market, you have 24 hours to test drive. Don't like it, full refund.
Notifications
Widgets
In all honesty, both phones are mind blowing. Look at the big picture and select what phone/service will benefit you the most.
I have a Dialog implemented with scrollview and a multiline edittext item in the scrollview. I see that I can use the scrollbar in the edittext as the scrollview will take over it. Can they co-exist and work together?

I'm very happy with how my Hero is set up at the moment, but there are a couple of apps which would make my life a lot easier, and conserve my precious battery!
Location based profiles using wirless location (and not GPS) I'd love to be able to arrive at work (or within 1500 meters of work) and my phone recognise this and switches on wifi, turn itself to silent, or choose a more suitable ringtone. I know that there are a few apps out there that use GPS to trigger, but this really kills my battery. I also know that wireless location isn't that accurate, but I'd only need ball park triggers anyway.
Time based app to kill certain features/apply airplane mode I've got Silent Time Pro, which switches my phone to silent at my bed time, but in an effort to conserve battery, is there an app which can also turn off wifi, GPS, auto updates and/or switch to airplane mode at specific times?
Does anyone have any recommendations for these, or do they not exist yet? Is it just me, or would these be quite handy apps?
If they don't exist, does anyone have a recommendation for me to set these profiles up manually, and maybe trigger them by means of a shortcut/widget? Obviously auto activation would be better, but I'm really trying to cut down on recharges, as it seems that my phones forever flashing orange at me!
1. Any competent music app. The default one is pretty worthless, and the "best" (I use that term loosely) 3rd party one I could find was probably MixZing, but it leaves a lot to be desired
2. Any competent camera app.. The interface on the default one pretty much sucks, and doesn't focus very well even with the green corners. If you look at Google Goggles, it has a VERY nice-looking full-screen camera that takes better photos than the default, but it can't be used as an actual camera, only for searching Google..............
Actually I am developing one application in that when application run first time it will create one txt file and save IMSI number in that file. when mobile boot it will matches it's current IMSI number with IMSI number present in the txt file. But I don't know how to check that file is exist or not.
View 2 Replies View RelatedI read somewhere (and have observed) that starting threads is slow. I always assumed that AsyncTask created and reused a single thread because it required being started inside the UI thread.The following (anonymized) code is called from a ListAdapter's getView method to load images asynchronously.
