I'd like to make a preference screen with a variable number of preferences, very much like the WiFi selector. A number of profiles should be clickable and possible to edit and in the bottom there should be an add profile button. Has anyone got any tips on how to accomplish this? All I've found is this: http://groups.google.com /group/android-developers/browse_thread/threa.

I am looking for a way to create dynamic preferences where I don't need to hard code the preference key and I could have a variable number of preferences. Basically, my application will let the user create a multiple number of profiles and each of these profiles will save custom values for a fixed number of preferences. So this way, the user does not have to change the preferences every time he wants this app to run differently, he can just switch the profile. One way I think will work is by subclassing all the standard Preference classes and calling their setKey method with my custom preference key, containing the profile name, but this is ugly. So is there a cleaner and more standards compliant way to do this?
View 2 Replies View RelatedIs there a way to have an global settings variable for an android application, which is accessable as well from any help java classes without giving them context?
I try to explain what I mean.
I have an application version as string value in strings.xml I can get its value from every android activity, but not from help java classes withought giving context What I do now, is saving it in a static variable of my first activity, but it seems, that sometimes it will be erased and set to null.

View 1 Replies View RelatedI currently have code that creates rows in a table that hold a string in column 1 with a RadioButton in column 2. There can be a variable number of these rows. That all works just great, but I want to add them to a RadioGroup so only one button can be toggled at a time. When I tried to add the dynamic RadioButton to the RadioGroup AFTER I added it to the table row, I got an error saying that the child (the RadioButton) already had a parent. I agree, it does have one, the TableRow.
can you have radio buttons tied to a radio group inside of a row or, should I just code my own toggle mechanism and avoid RadioGroup all together? I mean, I could code the onClick to unclick all other radio buttons, but I would rather not do this if I can use the build in RadioGroup.

Is copying the reference to the object and not the value of the object. Meaning, when I modify pos.top or pos.bottom, the original object gets modified. I'm guessing I am missing a concept of pass object by reference vs value here which I thought I understood. What is the fix here? Is it a problem with how I defined my custom class?

View 1 Replies View RelatedI want to know if there is a way to change the phone number in Settings> About Phone > Status. It's strange - I've only had the phone a few days, got one at the same time as my wife. For some reason the Phone number according to my device is my wife's number although it definitely has my SIM card in the slot and is functioning with the right number. Whereas my wife's device reads unknown in this field. How can I change it to my number?

View 1 Replies View RelatedWhen I tried to activate my phone, it wouldn't work. So I called Verizon from my landline and I told them and they had me activate it manually. They had me type in some random string of numbers to the phone dial pad and it took me to a screen where I set my phone's ID and other stuff manually (that the activation call would do automatically). I'm just curious as to what's in here. Does anyone remember the number? I can't remember it for the love of me and it's not in my call log.

WiFi itself is working fine, except the AP of the router i changed. Deleting all AP information and reentering all WPA2 data will change nothing. In my eyes the phone is not forgetting AP data completely when you try to delete an AP entry.

But I don't know how to fetch them. The main thing is that I am not getting that how to give the path of my xml file in application.

My file application.xml is stored in the raw folder and I have to access it with a variable name.
String xmlName= application.xml;
How can I fetch my xml through xmlName variable?

(The code basically runs when a new item is selected of a spinner and then plays a song, which later will be a variable based on what was picked, but I'm fine as it is for now). And I want to be able to use 'mp2' out of this public void, (I want a button which pauses it). How can I do this?
Anyone know of an audio player that will speed up the playback? It would be nice if it could keep the pitch the same but sped up is the goal. I used TCPMP on the Treo. This is great for listening to podcasts in a fraction of the time. Depending on the original audio, I can generally make everything out up to +25%.
View 4 Replies View RelatedI have noticed in my application(s) that after a call to Activity.finish() that the static variables that I declared in my classes still hold the values that they were changed to during the activity's life cycle. Upon the re-launch of the activity, the program does not re-instantiate the variables as declared or set them to the default java behavior. Is there something that I can do to cause this to happen, other than re-setting every static variable in my application?
View 3 Replies View RelatedI am doing an app related to football. I have a list view that will have various rows representing teams. In my custom array adapter I want to write some code that will present an icon for the team represented by the row. I have a drawable resource for each team (for instance for Indianapolis, Ind.png). In my code I can't refer to "R.drawable. Ind" because the Ind part is dynamic. That value would be in an array, like TeamArray[position]. As I expected, I certainly can't use R.drawable.TeamArray[position] because it won't even compile, it expects a literal name from the drawable folder. Is there a way to do this?

View 3 Replies View RelatedI seriously need help with a quite strange problem. I created a client which communicates with a server. Therefore, I have three classes. An activity providing a nice dialog to configure some data, a background service which checks the connection status periodically and a server class which handles the socket connection. Originally, the background service owned a server connection object but because I could not manage to provide data from the activity to the service, I decided to create the server connection class as singleton. The user is now able to change data in the activity (IP, Port, Username, Password) which shall be transmitted to the server object, if the save button is pressed. The data is read correctly, the activity calls the setter of the server class and the logcat also says that this data is correctly applied to the variable that stores the data in the server class. However, if I try to start the socket connection still the old values are stored in my variables although they've been overwritten before. What I am doing wrong, or how can I fix this?
