I am new to writing Android Applications, and I need to be able to implement the following functionality. When a user clicks a specific button, I want a customized "prompt" box to appear, containing several fields (a textfield, a password field, and a checkbox field). I would also be nice if I could add an image inside this box. How would I go about implementing this sort of functionality?

I'm populating a list from the DB and I have a image field in the DB which contains a URL to a image file.
ListAdapter adapter=new SimpleCursorAdapter(this,
R.layout.row, constantsCursor,
new String[] {"title", "subtitle", "image"},
new int[] {R.id.value, R.id.title, R.id.icon});
However, the other fields are populated, but the image remains empty.
I am trying to put recovery image on my eris. I just now figure out how to get to the directory my tools are in. What is my next step I don't get what to type into command prompt.

View 2 Replies View RelatedAlright, I'm a little new to the Android SDK, so forgive me if my question doesn't make sense or is very trivial. I'd like to add a custom field for contacts, that contains the contacts username on a website I'm doing this app for. And, with this custom field, I'd like to have the ability to click it (like "Send message" or "Call mobile") so that I can go to a specif Activity in my application, with a TextView set with the username that I just clicked on.Sorry if that is a bit confusing, if you need anything else let me know!

I don't want to use a dialog for each one. How can this be done? In the WiFi settings there is one that does this, when you want connect to a protected network, a dialog shows to set a password for the credential storage with 2 fields.
View 1 Replies View RelatedI'm working on a Java Android game. Games here generally need to use memory pools to avoid garbage collection.Making use of subclasses is a pain when using memory pools as you need to e.g. say how many Roamer and Chaser objects you want upfront and not just how many Enemy objects you might need.I would then have an update function that checked the "type" variable and updated accordingly. This is obviously a more C-like approach. It feels hacky though because e.g. a roamer enemy will have a "target" variable it never uses. I'm unlikely to have more than a 100 enemies in memory at a time though so it really isn't a big deal memory wise. I just want some compromise between nice code and speed.Does anyone have any comments on how best to structure this? Is merging classes like this going too far? Is this ever a good idea? Should I just use a regular class tree?

View 5 Replies View RelatedHere http://source.android.com/submit-patches/code-style-guide#shortmethods it is stated that :
"Field Names
* Non-public, non-static field names start with m.
* Static field names start with s.
* Other fields start with a lower case letter.
* Public static final fields (constants) are ALL_CAPS_WITH_UNDERSCORES.
also states that : "The rules below are not guidelines or recommendations, but strict rules. You may not disregard the rules we list below except as approved on a need-to-use basis." I don't like the "m" convention before private or package fields in a class... I really find this uninspired. I mean, if we try to apply good designs, the low coupling of the classes implies having few public fields. actually, in my programs I usually have no public fields, even when I need some I use getters and seters. so, why should I be forced to have almost all my fields in the program with an "m" in front of them? wouldn't be easier to have the few public fields, if there are any, with some "g" in front or something? or just use setters and geters as beans suggest? this really makes my code harder to read. also, following these guidelines, local temp variables used in the methods have no restriction so they could easily be mistaken for public global fields (also without restriction). this also I find to be wrong, as it is a probable source of mistakes. I understand to have a way of differentiating from fields, but private/protected member fields are the most used in an application, they shouldn't be less "readable". what do you think? should I follow the guidelines?

I have an app I am working on that does some math on a few variables and outputs the answer. Well that's the plan anyway. Being a total n00b at Android & Java I am not sure of a couple of things.1) I have created text fields in the layout file for user to enter values. Instead of text fields should I use numerical value fields, if such a thing exists? 2) How can you convert from a text field to a numerical value and back again?

View 4 Replies View RelatedI have a ListView that displays a set of notes, each with varying ammounts of data (i.e. some have a due date, others don't).Currently, each view in the list is a RelativeLayout containing a TextView for each field, plus two Button and a CheckBox. I then simply hide the unused fields by setting visible false on each one.This has worked well, but I'm about to add a lot more data fields to the notes and inflating that many unneeded views for each row will surely kill my app. I need a more dynamic solution.I've decided the best way to go is to create a custom view. How can I implement/design my view so that it can display a variable number of text fields without creating/ destroying textviews each time (which would be quite expensive and worse than my current situation), or maintaining a large pool of hidden textviews?

http://developer.android.com/reference/android/content/Context.html#getExternalFilesDir%28java.lang.String%29
File path = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
It does not compile on 2.1. The static fields DIRECTORY_PICTURES, DIRECTORY_MUSIC etc. Don't seem to be found. Using the filter api checkbox, I see that it was removed in Android 2.2 (or api version 8). So the manifest file needs to contain minSdk defined as 7.

View 2 Replies View RelatedHave been a long time user of Outlook and Blackberry and store a lot of information in the User Defined Fields. Those fields seem to have been eliminated from all of the Android Contact Apps. I don't see them in Motorola Corporate Sync, Touch Down or Moxier Mail. Am I missing something, can't believe the developers of Android apps would just skip those fields. Any App that I can store and sync those fields. Google Contacts has the fields. I have just upgraded from a Blackberry Bold to a Verizon Droid Maxx. Love the big screen on the phone, struggling with the touch keyboard and really struggling with losing half of my contact information.
