Android :: Query About ClickListeners
Sep 29, 2010
I have got around 15 buttons in my activity.
I just wanted to know that what would be a better approach to implement their ClickListeners. Should I write a single ClickListener and use Switch case or I should write it individually fr each button?
I got confused between these two because on a couple of blogs, it is suggested to write individual ones from the viewpoint of performance and efficiency but, considering cumbersome and complexity of overall code I feel like going with approach 1 i.e. switch case. Kindly give your suggestions about the right approach and the reason why I should prefer that.

In my app I need to query both the SMS and the MMS log to get the history of all incoming and outgoing messages.
This code has worked wonderfully for SMS:
CODE:......
But when I try the following I get completely different results:
COD:....................
The SMS query returns data that includes the message address (phone number), contact name, message subject, message body, etc... The same query for MMS returns a bunch of nulls or numeric value fields that I can't make any sense of. I really need a list of all MMS messages currently on the phone with the phone number or contact ID associated with it, and if the message was an incoming or outgoing message. In the SMS query results I can get the phone number from the address field, and the incoming/outgoing type from the type field but neither of these exist when I query for MMS.
Is there a different content Uri that I need to query for this sort of MMS data?

Is there a way to access and query the android SMS/MMS log? To clarify, the SMS/MMS Log is all the SMS/MMS messages sent by the host phone. It can be aquired by reading a cursor to the message inbox.

I have created a database for my android app which contains static data and does not require update/delete functionality thus when the app starts, I want to check if the db exists and if not then execute my dbAdapter class. I know its a simple if statement but I was just wondering the most efficient way to query whether the db exists.

I know there isn't bluetooth API in 1.0 SDK, but I have a doubt. I need to know the visible bluetooth devices. That is, I only need do a scan of the bluetooth devices and save the diferent addresses. I don't need connect to them.
I have read here
http://groups.google.com/group/android-beginners/browse_thread/thread...
that API "only expose functionality to use/control headsets (audio profile)."
And now my question: It is possible do this functionality? Can I find which bluetooth devices are visible?

I am about to start writing a web app for the latest smart phones using HTML5, CSS3 and JavaScript. I donut need a framework so much as a library like j Query. I looked at jQ Touch which is great for i Phone and apparently has support coming for Android too but I am looking to cover Blackberry device Software v4.6 upwards and WebOS 5 as well. Does anyone have any ideas of alternatives to jQ Touch or experience using jQTouch with Android's native browser, Blackberry's browser or Web OS native browser?

My Android app has a ContactsList activity in which I simply display a list of contacts that are on the phone. Only recently I noticed that my activity only displays contacts synced with my main Google account. I have two Google accounts on my test phone and ideally I want my activity to display the contacts for both accounts (or multiple accounts). How do I query across multiple accounts?

I am trying to write a simple test framework. This is what I want to do: My actual test is an apk file on android device, and I write a TestCase or some instrumentation for that which runs on host side. I trigger the test using adb commands or some IDE.I am able to refer to some examples which does above.Now what I want to know is any way of getting results back using any api available in TestCase or such class.This result can be any string value or an object too.
1. can I use TestResult for this purpose ? I expect it ot be similar to function calland return value from function.i.e. on completion of test I should get back the result in a structured way probably defined by me.Is this possible at all.
2. or return value is always going to be put to stdout? or logcat?
3.how do I parse and collect stdout or logcat prints into a file?
any input would be of great help.

I have a query that pulls everything from a database into a list view.
code:..........
I want only the records where the field KEY_HOMEID matches a variable called journalId which should be a numeric string.
I would also like to know how to bring the variable into my DatabaseAdapter... would ((resource)this.getApplication()).getjournalId()) work? resource is a class that extends application.

I am trying to write a select query from one single table in SQLite DB in my app where data exists.
This is the SQL.table has these columns - id(INTEGER), start_time(INTEGER), category(TEXT)
select category from tuuserid_pref where id = (select max(id) from tuuserid_pref
where start_time < '1242'); by the way I want to bind the value shown in 1242 which I have in an Integer variable.
I have written selects and inserts and updates without binding parameters and they work using db.execSQL and db.rawQuery functions but just cannot figure the binding parameters out.

I am using HttpsURLConnection to post data to a web server.
Here is the function I wrote to get the result. (see the code below)
Very strangely, when the function be first called in my program it would very likely return -1; and then I re-call the function after the first call, it would always work ok.
So I wonder if there is anything I am missing in the code that when the function be firstly called, the missing party is be "initialized", in that the followed call goes OK.
Here is my code of the function:

I have setup 2 test contacts in my emulator.
I'm running the following query, it should pick them both out, populate my domain object, and add to a list. The output at the bottom should therefore be 2, but it is 5, why is this? (cursor.getCount() is 5 instead of 2)
I have stepped through each iteration of the while loop and it is retreving the same contact multiple times, but with different values for POSTCODE, such as the phone number

I have been playing around with the SearchableDictionary sample application trying to understand it.
I set a breakpoint in DictionaryProvider.query() and verified that it's going in there when I turn on search for this application (settings > search > searchable items > Searchable Dictionary).
Then I tried modifying the AndroidManifest.xml file, changing the launch activity to .WordActivity --
CODE:..............
I also had to change WordActivity so it would startup (albeit not be useful) --
CODE:...............
My expectation was that when I ran it and typed something in the QSB (search box on the main android page), it would still trigger the breakpoint. It's like it doesn't even recognize that the app should be part of the search anymore. I try moving the manifest changes back and it goes back to working.
The thing that led me down this path was that I am trying to write my own ContentProvider, and I can't get the QSB to call my query method. So what gives with this sample code here? What is preventing (or enabling) query() to be called from the QSB?

When I send an SMS on my Android emulator, it goes to the content provider:
content://sms/sent
right?
So I wanted to get the last sent SMS from the content provider. So I used this Uri as you can see above, and, I used the method query, with the Content Resolver Object. And I got the cursor, and used the movetofirst() method, so I would have the last sent SMS. Check the code below. I hope it helps.
package com.sys;
