Android :: Changing Variable Affects Indirect Variable (value Vs Reference)
Sep 26, 2010Is 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?

Jan 6, 2010I would like to show a custom input field (specifically, one containing only 9-0 and two extra buttons containing decimal separator (, or .) and a delete button). I could create a custom IME, but (as far as I know) that would have to be set by the user as the system-wide input method. Is there a way to implement an input method and bind it to a specific input field?

Passing Variable From One Class To Another
Feb 20, 2012I would like to setup a boolean called dFlag in the main.class of my program and reference it in another class.
I already have it setup to work locally just hitting a snag on how to do it.
Code:
public class Main extends Activity {
boolean dFlag; ///Debug flag, true=enabled | false=disabled
}
public class Other extends Activity {
if(dFLag = true) {
///Output debug message
}
}
Or is there an easier way to do what I want without having to re-invent the wheel so to speak?

View 32 Replies View RelatedAndroid :: How To Deal With Storing Bookmarks
Oct 13, 2009I am essentially using a listview but am looking at providing a bookmark functionality. I am thinking that I should store the item attributes in a file when bookmarked and retrieve when required to populate a bookmark listview.
I was wondering if there is a de facto standard used in achieving this or do I follow just the "writing into a file" and "reading from a file" when necessary style?
Android :: Utility For Storing A Static Map?
Feb 19, 2010I've got a common use-case wherein a user selects one item out of many (say, on a spinner or autocomplete list), then enters the data. For example, let's say the user selects a country. Ultimately, the data I want is the country code, not the country name; but the users will want to select based on name, not code. To put it another way, user's will select "United States", but I ultimately want that to translate into "US".
There are a lot of countries. Is there an easy way to setup a mapping in Android to hash from the name to the code? I've thought of a few solutions, none of them are quite satisfactory in my mind:
A database containing country/code, which I can query on. Setting up all countries as strings in strings.xml, then retrieving the resource by name. Creating a huge Map in code and using that. (This is the least satisfactory answer).

View 3 Replies View RelatedAndroid :: Getting Variable Out Of Public Void
Apr 21, 2010I have this code:

final MediaPlayer mp2 = MediaPlayer.create(Textbox.this, R.raw.hero);

(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?

View 4 Replies View RelatedAndroid :: Static Variable Instantiation
Apr 1, 2009I 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.

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 RelatedAndroid :: How Do I Refer To Drawable With Variable
Sep 13, 2010I 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?
