I have an image put on an ImageButton, which looks good on a mdpi (medium-dpi) screen. However, when the device has a hdpi (high-dpi) screen, the image is still pixel-by-pixel accurate, which look small on the device screen.How do I make such that the image (and therefore the ImageButton) scaled based on the density-independent pixels (dp or dip) instead of pixels?

the cpu scaling of Android.. First, do the system use the lowest frequency when not in use? Aka screem off..After i unlock the phone do it always scale to max frequency or scale it based on the cpu needed? For example write a text makes the phone use thr same freq as playing a game?

View 1 Replies View RelatedI read the official document about supporting multiple screens http://developer.android.com/guide/practices/screens_support.html
According to that document, I should just create different directories for different resolultion.
Now the question. How to support devices with normal screen and high density or low density?
I ask it because, there are two posibilities (WVGA800 (480x800) and WVGA854 (480x854)) and (WQVGA400 (240x400) and WQVGA432 (240x432)) and I don't know where to store some background images for them.
I would take drawable-normal-hdpi or drawable-normal-ldpi, but how to make difference between 480x800 and 480x854 or between 240x400 and 240x432?!
there is anyway you can make a Digital scale app? or if anyone can please , Let me know if it's possible willing to pay someone if so. My family owns a jewelry shop and it would be convenient to use my phone to weigh jewelry or gold out

View 5 Replies View RelatedHow to get the screen density programmatically in android?
I mean How to find the screen dpi of the current device?
Can you please tell me how can I specify dimension of layout for different density of screen?
i.e. the layout are the same across different densities, but some dimension are different.
how can I do that?
I'm getting ready to release my first application the marketplace. It's being written for devices running Android 1.5 and above, however there aren't any specific folders for the three different screen densities (I think those came around in 1.6). Should I make these folders myself? Where should I put image resources for the different densities and what should I put in my Manifest?
View 2 Replies View RelatedI'm being confused by the 'screen density' concept in Android. I knwe that dpi (dot per inch) came from the printing device. 160 dpi means 160 dots in every inch on the paper. However, when dpi is used for the screen density, for example, what's mentioned '160 dpi screen' in Android document, what's the meaning? 160 pixels on every inch of the display?
As described in http://code.google.com/intl/zh-CN/android/reference/available-resourc..., 1 dip (density-independent pixel) means 1 pixel on a 160 dpi screen. Why does the ratio of dp-to-pixel not necessarily change with the screen density in direct proportion?
When the dpi is changed from 160 to 80, how many pixels will 1dp will take? 0.5?
I can hardly understand why dip/dp is introduced into Android.
I have a class that extends LinearLayout and handles drawing to the screen. (it is in the early stages) How would I go about determining the dimensions of a screen and resizing the images, etc., that this class is drawing to the screen on the fly before actually drawing them to the screen?
What I'm trying to accomplish is support for devices that have varying screen dimensions and resolutions from the same code base, with each device being scaled properly.
A lot of hay is being made over the iPhone4's 326 ppi screen density. I was just curious, for comparison purposes, what's the pixel density of the Evo screen? This would be an easy calculation to do if I knew what the horizontal and vertical dimensions of the screen were, but I can't seem to find that information anywhere.
If anyone knows the pixel density or even just the exact X and Y dimensions of the screen..
Due to my changing of the screen density i can't get it via play store. can't see a working link on google either.
View 9 Replies View RelatedI have a widget on my home screen with several ImageButtons which have default background images. Through the configuration activity, I can change the image on any of the ImageButtons. The problem is that when the screen is rotated, the image on the ImageButton disapears and it changes back to the default image.
I don't know why this happens or how to fix it
I am developing a simple widget which has a couple of buttons in its layout.
Before the widget gets added, the configuration activity is displayed, where the user can choose if the widget makes any sounds when the buttons get pressed or not.
Thus, a user can put two instances of the widget, one where he chose sound to be activated and another where he chose the opposite. However, I can not seem to be able to reproduce the expected behavior (that one reproduces sound and the other doesn't).
The buttons' behavior varies according to the flags specified to the PendingIntent:
- FLAG_UPDATE_CURRENT seems to override the previous intent/setting - no flags (0x00) seems to ignore any intent/setting after the first instance of the widget is put.
What I want to do: I want to be able to configure different instances of the same widget to behave in a different way, according to what the user specified in the configuration activity. I am attempting to do this with the help of the appWidgetId of each instance:
I have tried the following when assigning an action to the click of the button:
CODE:.................
This results in the first widget acting properly (The IDs printed in logcat are as expected) When adding a second widget, however, the first widget starts reporting the second widget's appWidgetId in its onReceive(), when it previously did no such thing. (because of the FLAG_UPDATE_CURRENT, I guess)
How can one make different instances behave in a different way? Is there a way to do this with the help of the appWidgetId?
I have elaborated a widget application for the purpose of debugging this problem which tries to be minimal, while reproducing the (un) desired behavior: http://www.2shared.com/file/8243059/b6519584/IntentTesttar.html
i am developing application on android but i have a problem, how can i fit my app to every screen size and also tablets?
I mean if i have images in the game and background so lets say it looks fine on galaxy s3 but on tablet it will look very small , how can i make the app scale itself to the screen without hurting the image and background looks.
Is there a way to scale down or zoom out in an app so the screen is smaller so I can achieve a better resolution?
I specifically want to use it for MyBoy since the app blows up the size on my Note 2 and it doesnt have as good clarity if I could make the screen smaller.

View 1 Replies View RelatedAs per managing resources(images) in > Android 1.6 version, we need to keep different-resolutions image in Drawable-Hdpi, Drawable-Mdpi, Drawable-Lpi folder particularly.
And as per this page: http://developer.android.com/guide/practices/screens_support.html ,
In Low density section - there are three resolutions used: 240*320 , 240x400 , 240x432 for the Small screen, Normal Screen, Large Screen particularly.
same way for Medium density section - there are three resolutions used: 320x480 , 480x800 , 480x854 for the Small screen, Normal Screen, Large Screen particularly. and same way for High density ........
But i am confused here:
(1) How do i come to know that whether small, Normal or Large screen is used, i mean is there any way to know ?
(2) How do i come to know which type of density i am using ?
(3) And in Drawable-Hdpi, Drawable-Mdpi, Drawable-ldpi folder, which resolution's image we should keep particularly?
Is it possible to make an app choose a particular APN automatically?
Or at least direct the user to the APN selection screen?
Also I've been wondering, can an APN be used from any cell provider? Let's say I have two providers: A and B, can I use APN-B within A ?
I'm confused regarding the densities. I see that with medium density, the screen resolution could be either 320x480, 480x800, or 480x854. So if I have an image thats 300px wide in the mdpi folder, how is it going to look the same size on all 3 different screen sizes (mainly 320x480 vs the other 2)? And by look the same size, I mean scale to be bigger or smaller depending upon the screen size.

On a similar note, is there a way to make the phone lock automatically (like an app)? It's also annoying to have to manually lock it: I'd rather keep waking it up (if it was indeed idle and not running a program) than forget to lock it and dial/message everyone in my contact list from my pocket.
I have wallswitch or w/e for the main home wallpaper that switches it periodically, but is there an app that does the same for the lock screen, I don't care if it is a full on lock screen replacement or not, just are there any out there?
