Android :: Desnity-Based Resource Selection?

May 27, 2010

I have a graphic (test.png) of which I need to include density- specific versions, so I put a large (150 X 150) version in res/ drawable-hdpi, and a smaller (100 x 100) version in res/drawable-mdpi. I then include an ImageView, and set the src attribute to @drawable/ test. In the Eclipse Layout editor I can change the configuration between mdpi and hdpi configurations and the correct version of test.png is displayed. Unfortunately, when I compile and load onto a device, the mdpi version is always chosen. The only time the hdpi version is chosen is if it is the only option. I have tested this on the Droid and EVO 4G, which are both running Android 2.1 Update 1, and also the emulator with the same results. For what it's worth, I have also tested on a Motorola CLIQ (running Android 1.5) and an Ion (currently running CM 5.0.7) and they get the mdpi version (as expected, since they are both mdpi devices).

Android :: Read Resource Based On The Current Theme?

Nov 22, 2009

In my case I need to be able apply a color conditionally (for example based if an item is read or unread) so I need to be able to read the "read" and "unread" colors from the current theme and apply them appropriately.

I gave the color special attribute name in my attr xml file and assigned it different values in 2 different themes. if I do getResources().getColorStateList( <my attribute resource ID>) it fails because it can't find the resource. It seems like something needs to first resolve the attribute Id to the Id of the resource in the current theme, but I am not sure what does that.

Android :: Spinner - Don't Display Selection / Set Selection Text Color As Transparent?

Aug 4, 2009

I'm trying to use Spinner as a button with selection pop-up. Basically I want an icon and when user clicks it - the popup list is displayed and user can make a selection. The Spinner happily accepts icon image as drawable background. Unfortunately when I select a value the text overlays the background. Is it possible to set selection text color as a transparent? Or maybe there's a better way?

Android :: How To Use Resource Within A Custom Xml Resource File?

Aug 3, 2010

I have an XML resource file:
<resources> <section>
<category value="1" resourceId="@xml/categoryData1" />
<category value="2" resourceId="@xml/categoryData2" />
<category value="3" resourceId="@xml/categoryData3" />
</section> </resources>
Using XmlPullParser, on the START_TAG, I can use:
int value = parser.getAttributeIntValue(null, "value", 0);
to get values 1, 2, 3...however:
int resourceId = parser.getAttributeIntValue(null, "resourceId", 0);
doesn't work...it just yields the default value 0, or whatever I change the default value (3rd parameter) to be. Does anyone know what I am doing wrong or if this is possible?

Android :: Using Spinner Selection As A Value

Nov 20, 2010

I am trying to get a Spinner to work in Android. It displays fine and I can select any one of the options in the list. But how do I transfer that to a string?I would have thought in the code below that 'selected' would hold the selected string, but I get an 'Illegal modifier for the local class YourItemSelectedListener; only abstract or final is permitted' error on the 'YourItemSelectedListener'.What am I doing wrong?

Android :: Gallery With Folder Selection?

Mar 29, 2010

I have a Droid just running stock 2.0.1. What I am looking for is a photo/picture gallery app that simply let's you select the folders that you want to display in the app. I was fine with the stock gallery for awhile, but then I started getting a variety of apps that store pictures in various folders (the worst one being Touchdown for Exchange which puts almost every attachment in a new folder). The stock gallery now takes forever to load up, as it is loading a TON of folders with images in them. Really it makes it almost useless at this point. This was the main reason I switched to MixZing for audio, as it let me narrow my library down to the few folders that actually mattered.

Android :: Enable Selection In Webkit

Jun 13, 2010

I'am looking for a way to have a webview content selectable in the very same way as the stock browser does.
I should note that Dolphin HD shows exactly the same text select functionality as the default browser (same icons, animation, etc), so it really should be possible. But I can't figure out how.Until now, all i found was this function, which kind of work, but doesn't allow the user to expand/shrink the selection.I just discovered that long touch copy/paste is part of HTC Sense, not Stock android. Still, it'd be useful to find out how to enable that on a webview, even just for HTC users. Anybody knows ?

Android :: ListView Checkbox Selection

Nov 10, 2010

I kind of have a 2 part question here.

1) How can I populate my ListView so that strings are what is displayed, but when items are selected, a non-visible id value (contact id from phone contacts) is the value that is actually used?

2) I have a ListView that's using multipleChoice mode for item selections. It's popluated with names from my contacts list. When I select an item in the ListView, I want that selected item to trigger a call to my SqLite routine to store the value into a database record. How do I make this event fire when an item is checked in the listview?I had hoped to be able to use something like the onClick event for each checked item, but have made not one bit of progress.

Android :: Default Selection Not Working

Oct 12, 2010

I hope, my issue would be clear for you from my question title. I have three linear layouts in each row of the list view. One linear layout contains an Imageview and the other two linear layout contains text views. These three linear layouts comprise my list view row. But, to my surprise, the listview default selection(orange colored) does not work when I move the trackball of mouse or when I select it from the phone.

Android :: Multiple Selection In Email App

Oct 14, 2010

How do you do a multiple selection in the default mail app?

My server's spam filter works pretty well, directing most of the spam to my Trash folder, and very little "real" mail. So when I look in my Trash folder I might have 30 messages, and 28 of them are spam. How do I select all 28 of them for deletion in one fell swoop, so I don't have to tediously delete each one one-at-a-time?

Android :: Calendar Home Selection?

Feb 23, 2010

On my blackberry i was able to choose whether i wanted Month, Week, Day, or Agenda as my initial screen the calendar opens up to.

Am i able to do this on my Nexus One? I use the Agenda 99% of the time to see what class i have next along with whats ahead in my day. However whenever i open the app it always on the Month section and i can not figure out how to change that. I realize once I've selected agenda it will stay there for the next couple times if i exit it using the home key rather than the back key, however that only lasts for a little while.

How or have another calendar app recommendation. Im using Gcal.

Android :: Spinner Selection Box On Activity And Dialog

Jun 22, 2010

I have a spinner selection box on my activity, but now I want to remove the spinner from the main view and make the selection available by an option from the menu button. How do I get the dialog the spinner shows if I click it without having the spinner? Currently I fill the spinner using a SimpleCursorAdapter like this:

Cursor c = db.fetchAllSets();
SimpleCursorAdapter adapter = new SimpleCursorAdapter(this android.R.layout.simple_spinner_item, c, new String[] { DatabaseAdapter.SET_KEY_NAME }, new int[] { android.R.id.text1 });
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_it­em);
mSetsSpinner.setAdapter(adapter);

So now I'm planning to remove the spinner from my activity, add a new button to the menu and in the onOptionsItemSelected(...) show a dialog with the list of available selection - just the way it is right now after clicking the spinner object.

Android :: Radio Button Selection Changes Toast

Apr 29, 2010

I was writing a simple test application. There are two radio buttons within the app. There id's are "radio_red" and "radio_blue". I wanted to create an onClickListener event that read the text associated to the button and then returned a basic "Right" or "Wrong" toast.So far no joy. Here is my code snippet. I've checked my "main.xml" and the text associated to the buttons are referneced correctly. I added trim to make sure of that. However, all that is ever returned in the toast is "none." What am I missing? Thanks in advance for any help.

Android :: Get User Selection And Convert It To A String

May 5, 2010

I just got a Droid, and after having used it for a while, I felt like I wanted to make a program for it. The program that I am trying to make calculates the actual storage capacity of secondary storage mediums. The user select from a list of units that ranges from KB to YB and the size the entered gets put into a formula depending on the chosen unit.However, there is a bit of a problem with the program.From my testing,I have narrowed it down to the fact that the user's selection is not really being obtained from the spinner.Everything I look up seems to point me to a method quite similar to how it works in J2SE, but it does nothing. How am I actually supposed to get that data?

Android :: Way To Deselect Any Trackball / Trackpad Selection?

Is there a way to programmatically deselect/wipe whatever the user has selected with the trackball/trackpad When I hit the back button on an Activity, the Activity it falls back to has a button that is selected as if the user had used the trackball/pad. I'm not sure what is selected on the previous Activity, but obviously something is. I'd like to programmatically wipe any selection just before the Activity finishes.

Android :: Gallery Widget - Focus And Selection Gone?

Aug 26, 2010

I'm trying to realize how the focus and selection in the Gallery widget is doing their job. I'm facing weird situations when trying to update information (TextViews and Spinner) upon a selected item in the Gallery. The focus and selection is lost. So, using the resource gallery_item_background will end in showing the "unselected" background for the current selected image. I have used the .xml that came with the android sdk, and I can't realize how this is happening. I have set setFocusable(false) and setFocusableInTouchMode(false) to all other Views to try out (and true for the Gallery) without any luck.

I have also add 'in-situ' debug, that is, a menu that updates differents widgets when onItemSelected() is called. So I can see while using the application how the background resource is applied. When set to 'no update' the obvious thing happens. None of the widgets are updated with new values, and the background resource works as expected. When set to 'manual update' (an update in the listener that do: .setText() on the textview) does work depending the current View that is showing the TextViews (I have a ViewFlipper that display 2 differents Layout of the TextViews)...............

Android :: Need Subject Of Phone / Carrier Selection

Feb 1, 2010

I need a little friendly help on the subject of phone and carrier selection. My options are; Subbed Nexus One with T-Mobile plan Unsubbed Nexus One with cheaper T-Mobile plan roid/Eris with about Verizon plan (I get a discount) and wait for the Nexus One on VZW. Eventually I would like to get the Nexus One, but Verizon's plan will actually be cheaper than T-Mobile because I get a discount with them. That is unless I get the N1 unsubbed, but I think is a lot for a phone. I would be super paranoid about it messing up or me breaking it. VZW has better coverage overall, but they both have about the same where I actually live. I have about two weeks before I have to do something, my old contract ends soon.
