Android :: How To Deal With Application Widget Having Variable Sizes?
Apr 24, 2009
I want to create an app widget that could take up a different number of "cells" on the home screen, but I don't think that the app widget framework easily supports this. I know that an app widget can have a configuration screen, and I'd like the user to be able select a sort of small, medium, or large size for the widget as part of my configuration activity. Unfortunately, I don't think that this is possible, correct? Based on the minWidth and minHeight properties, the Launcher app will assign a number of cells that I can't configure at run time.
For instance, if I want a weather widget that has a current, hourly and weekly format that take up 1, 2, and 4 cells respectively, I can't do this at run time. Instead, I believe my only option is to export 3 different widgets and have them all listed in the widget picker dialog as something like "Weather - current conditions", "Weather - hourly forcast", and "Weather - week long forcast".

About the Eris. On version 2.1 does Beautiful Widgets (the app) show under "data" on your SD card? Should it? If it doesn't belong there should and I delete BW - will the clock/weather on the home screen still work? I expect the HTC / Android clock weather deal is a widget vs an app? Or is it an app and what is it called?'

What I'm trying to do is have a clock widget of different sizes (i.e. 2x2, 3x3, 4x4 etc) in one apk and a configuration activity to be able to select which size to add. From what I've learned from documentation:
Widget size is specified in <appwidget-provider> tag in respective xml file
Also in that file I set up the configuration activity for that provider
So it seems that size is a property of AppWidgetProvider and I'll need to somehow create another provider from the code in configuration Activity of the first one. I have read this and this. First one explains how to put multiple wigets in one apk, but it's not clear how to select between them in runtime. Second one is about changing layouts, but not size.

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?

I've been reviewing the Supporting Multiple Screens documentation on the Android and I just need some additional clarification...
It's my understanding that designing three unique interfaces (ldpi, mdpi, and hdpi) would be the best way to go about supporting all the potential android screens with minimal scaling/distortion.
Yes, I know there are similar questions posted, however... If I create an image for the benchmark mdpi (let's say my image is 300x210, just for example) how to I determine what size I will need to recreate that image at ldpi & hdpi? This post as well as a google search leads me to believe that ldpi is just 75% of the mdpi image, and the hdpi is 150% of the mdpi image. Is this accurate?

Is 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.

I want to create a global variable store for a list of user defined objects. I have a LinkedList of Feed (a user defined object) that I need to be made available to a new Activity that is created. This list is displayed using a ListView and so when an item of the ListView is clicked, I need the correct Feed index to be 'passed' to the new Activity. I have no problem doing this as I create an Intent and then pass the id of the selected row. I need the new Activity to have access to the LinkedList of Feed objects.
There are different ways to do this (explained here - http://code.google.com/android/kb/framework.html). I want to use the option (quoted from link above): The android.app.Application class The android.app.Application is a base class for those who need to maintain global application state. It can be accessed via getApplication() from any Activity or Service. It has a couple of life- cycle methods and will be instantiated by Android automatically if your register it in AndroidManifest.xml.
I want to use the above method as I could then fill the LinkedList at application start and then use it throughout without any duplicates etc. Does anyone know how the android.app.Application class can be used as a global variable store that can be accessed from other classes? I cannot find any more information on this method of passing information between Activities within a single application. Any information regarding passing user defined objects would be useful and specifically how to get the above idea to work.

I 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?

We want to add below update sql into our content provider:We found current update of content provider does not support it, which would not recognize the "column1" of "column1 + 1" as column name. So we have to add execSQL method into ContentProvider and I think it is dirt. So I wonder if anyone know how to do such thing with ContentProvider or any more elegant way to achieve it.

My application needs to intensively manipulate (read-write) on some structured text data.The size of the data is significant 1Mb. And there is initial data available for the user to start with.My idea is to put this data as a file in the .apk. Then, on initial application launch to read this data and populate Android SQLite database with it. Then just work with this database. But after the database is populated the data file is no longer needed. And I'd like to remove it to free some memory. Alternate approach is to work with this data file instead of SQLite database. But I assume SQLite would work a magnitude faster then i/o on my data file..

I am trying to develop a Android Google Map application, which is basically Gmap with my own marker geo layer. Since android.com is banned in China, I have to search support from Google user groups. I have no idea which groups I should call for help, android group or google map group. Anyway here is my questions:
I am working on Android SDk1.5. I want to reproduce the floating buttons presented in android Google map, which stands for three buttons: ZoomControl (left), FocusChange (middle), and ListControl (right). (Pls check ref1. ) I checked some open source projects, if designer can place these controls in the layout.xml with relative layout, to place them over (on the top of) the mapview. It may solve some problem, however in the SDK1.5' add-on gmap jar, the getZoomControl is discarded. I can only setBuiltInZoomControl(true) to enable the builtin zoomcontrol. By default, the "BuiltIn" Zoom Control is placed at Bottom/Center. (Pls check ref 2.) I have no idea how to relocate the "BuiltIn" Zoom Control to the left as native GMAP does.
So: How to relocate the BuiltIn Zoom Control ? How to add addtional custom control (buttons/overlays) with BuiltInZoomControl ? What functions should be overriden for the detail implementaiton, Such as synhcorization with the visibility? I am appreciated if the answer can be offered with code snippet or references to any internet site.

I've got a query, (I'm using rawQuery())
SELECT * FROM <table>
I'm then storing what it returns using a cursor. From their what I want to do is, start at the first row so.. cursor.moveToFirst() then take each column , column by column and store its particular value in a variable. I then want to move onto the next row and do the same. So I guess my question is How would I get cursor to deal with multiple columns?

I am learning how to program on Android phone. However I am unsure how to make my application work for the different screen sizes and resolutions.
I read the tutorial on the android site and still unsure how to do it.
First I know there are different files so could make a layout for each of the sizes but my problem is most of the screen needs to be dynamically created so there would not be much to put in these files.
So I am not sure how to android to re size dynamic controls based on the screen size.
I have also read it is bad practice to make controls in anything but the xml file as it separates view logic and programming logic. However they never talk about if you need to make these controls dynamically what you should do.
So is there some other way to do it that is considered good practice?
Edit

To your question: It's dynamic because
the buttons in my example grow and
shrink depending on one of the 3
possibles sizes, because they use
scaled pixel (You probably know that
you don't have to deal with screen
sizes itself). So a scaled pixel
compared to a real a pixel has a size
of 0.75px, 1.0px or 1.5px. Android
automatically and dynamically adjusts
it to the actual size. So you don't
have to care about this in your code.
So if I use scaled pixels then I don't have to worry about different screen sizes?
At the moment I don't know an example
except in games where you have to deal
with "real" pixel. But if you want use
it, multiply it with the value of the
current density. This is your "ratio".
I don't have the example with the ball
anymore but I have another which uses
the same technics. You can run it on
different screen sizes and you will
see that the buttons will always fit
into the layout. You could use the
same technics for your intents. In
this example you can scroll with the
"Scrn" buttons from one view to
another of 4 views. (At the moment
they all have a black background so
you don't see that they are different
views). The "Enter" button exits the
test. It's an Eclipse project. You can
download
So if I want to deal with ratio then I use real pixels and not scaled pixels? What advantage does this give me?
will scaled pixels work with changing from portrait to landscape( ie will it fill up the new found space)?
Finally should I make the controls now through code or is there another way? As I said I am getting data from a webservice that must look like this
checkbox label label
It can be one record or 10,000 records I don't know so these have to be appended to something that is like a window panel( the controls in there get a scroll bar).

I've got a quick question about screen size support. Currently, I've got an application that is rockin' along just fine on 1.5 and 1.6. Today the client called and says they want to run on Droid. While I've downloaded the 2.0 SDK, I'm a little wary of compiling against it. Will it break 1.5 and 1.6 compatilbility? How will the "medium" phones (G1, MyTouch) know to use those layouts?

I see that people here have walked out of mobile phone stores with some great bargains. I've been living off my wife's old contract phones for years and I always hated going into stores to look at phone as sales people always tried to sell me stuff I didn't want / need. I've now decided it's time to invest in a Desire with a contract (T-Mobile). Their �10 a month for 100 mins & txt (phone �164) is tempting but I probably prefer 600 mins & unlimited text for �21.35 (after redemption) from buymobilephones.net How's the best way to approach a sales person in a store bearing in mind that I'm a new customer? Are they fairly flexible when it comes to discussing contracts? I just fancy walking in and asking if they can match a certain contract deal on the internet!?

Hello, I would like to ask what settings are necessary for my application to be available on all screen sizes: Is it enough to compile it using SDK 1.6 (but target is set to 1.5 and API level to 3) or maybe I have to set target to 1.6 and API level to 4?

supporting multiple screens (sizes and resolutions). I´ve searched not only this forum but many different websites and the android documentation but I´m probably doing a small mistake so things are not working properly.
Well, my main layout was designed with a HVGA screen, and it works great. When I try the same app on a WVGA, FWVGA, WQVGA or FWQVGA, I always get an unused space in the end of the layout because the screen ´s "heightnes" is proportionally bigger than HVGA´s.
So I consulted the documentation and decided to give a try on resource qualifiers, so I then created a nonsense UI and placed it on layout- large, created a new AVD using the WVGA skin and launched the app. Well, all I got was my old and not well stretched layout. The same happened to a FWVGA AVD.
This is the first problem. The second is: medium high density medium size screens and medium density large screens have the same resolution: how can I create a layout that is loaded for both, but not for (for example) medium size medium density or small size medium density screens?
