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?
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?
Is it possible for my android application to dynamically adjust the no of column and no of row of my TableLayout based on orientation?
For example, when in landscape mode, the TableLayout is 3x2 and when
in portrait mode, the TableLayout is 2x3?
i have tried almost everything i can think of to center a programitacally created table in a pragmatically created layout. I've tried all the usual layout params center setting but still nothing: Score List is a set of pairs of scores (Name, Score). I'm just looping through and adding them to cells in a table and its always aligned left when i run it.
ArrayList<Score> scoreList = new ArrayList<Score>();

I am currently learning about widgets in Android. I want to create a WIFI widget that will display the SSID, the RSSI (Signal) level. But I also want to be able to send it data from a service I am running that calculates the Quality of Sound over wifi. Here is what I have after some reading and a quick tutorial: public class WlanWidget extends AppWidget Provider {RemoteViews remoteViews; AppWidgetManager appWidgetManager; Component Name thisWidget; WifiManager wifiManager; public void onUpdate(Context context, AppWidgetManager appWidget Manager, int[] appWidgetIds) { timer timer = new Timer(); timer.schedule AtFixed Rate(new WlanTimer(context, appWidgetManager), 1, 10000); The above seems to work ok, it updates the SSID on the widget every 10 seconds. However what is the most efficent way to get the information from my service that will be already running to update periodically on my widget? Also is there a better approach to updating the the widget rather than using a timer and timertask?
View 12 Replies View RelatedHere 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 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 ?

I have a database that gets updated by a background thread. Is is possible for the UI ouput(using a listview) to change when a database entry is added/deleted? I've seen examples of using SimpleCursorAdapter and listViewAdapters and I'm not sure which to use and if it would even work.
I found an "efficient" listViewAdapter which would work great for me since it doesn't call findViewById often and I can change the data structure to hold exactly what I need, but I don't know how to hook it into my database adapter so it dynamically updates the output when there is a database change.

I've been trying to update my phone now for nearly two weeks, trying various options, yet nothing I do helps in any way.I started off just running the update from SEUS with my phone as i've been using it.the updater started, gets about 70% through "Preparing" and pops up an error "Unable to install or start software update components." Closing which pops up "try again" or come to this site.I then tried uninstalling all installed components, same result as above.I then tried a Master Reset to factory setting, same result as above.I then disable the Firewall and the Anti-Virus, same result as above.Basically, i'm at the end of my tether, this should not be this difficult, I should not have to jump through this amount of hoops.If there was a way to legitimately root the phone (keeping warranty), I could already have Froyo installed, instead of this irritating mess thats causing me nothing but headaches.
View 4 Replies View RelatedI will like to know if we can continuously call some service for fetching results and displaying in Autocomplete list.I have one screen with the text box and when user starts entering in that textbox the autocomplete should get filled with the data. The data will not be hardcoded and will be fetched through http connection.I think I need to call http connection in onTextChanged method of Edittext but is that the perfect solution.Moreover, should this type of implementation done in mobile application. Since, this feature is web based. Can this be done in mobile application too?

View 2 Replies View RelatedI have an activity that needs to display an alert to user when location is updated,
but i need first to get current location (update last known location) and then start a location update listener to display alert in this activity.
Basically what i need is to display an alert if location changed from time activity was created.
If i use getLastKnownLocation when activity is created, it might be outdated, then the requestLocationUpdate listener is called a few seconds from activity creation time.
How can i do this?
I am currently unable to update an existing contact record's phone number. I am able to insert a new phone number to an existing contact record but unable to delete or modify existing phone number records of a contact. Is there a way to either: - delete an existing phone number from a contact record. or - update an existing phone number of a contact record.
The sample code is as shown below:
To delete existing phone numbers of a contact record: row = getContentResolver().delete(ContentUris.withAppendedId (Phones.CONTENT_URI, uid),null,null);
Log.v(TAG,"row =" + row);
The row value is always 0 even if phone numbers are present. Thus, the deletion does not take place. To update a phone number:
Uri PersonUri = ContentUris.withAppendedId(People.CONTENT_URI, uid);
Uri PhoneUri = Uri.withAppendedPath (PersonUri,People.Phones.CONTENT_DIRECTORY);
ContentValues values = new ContentValues();
values.put(Phones.NUMBER,"1234567890");
values.put(Phones.TYPE,1);
row = getContentResolver().update(PhoneUri,values, null, null);
This throws a unsupported Operation exception.
I've just tried to update my X10 to the new 2.1 firmware, with absolutely no luck.I get through all the stages, everything works fine, no errors reported, everything reset on the phone, all looked great.But, when I check the version its' still at 1.6. And every time i connect it to the PC after the upgrade, it tells me there's an update available, just to go through the same thing again, and still leave me with 1.6.
Any ideas?I tried uninstalling and reinstalling PC Companion.No change. I'm on Orange UK, and the update only became available to me today.

If I try it on a wifi connection (perfect connection until I try) it stops the download immediately. Either "download stopped" or "download unsuccessful". On 3G It's basically the same but slower. Since this started, last night, everything is slow on 3G. I'm also having a separate problem updating apps. I keep getting the message "Sorry, there's not enough space to install this item." I have not installed anything new and have uninstalled some apps to clear some space. I keep getting the message even after I uninstalled several games. I now have 93MB free on my phone. I'm sure that an update to an app that I already had installed doesn't need more space than that. My wife just updated the same apps on her EVO.
