Android :: Handle Imaged Background And Buttons On Different Size/proportion Displays
Mar 27, 2010
IŽm working on the UI of my first app and IŽd like it to work on as many different devices as possible. IŽve read on the net about AndroidŽs rule not to resize bitmaps on views (background, buttons, etc), is it true? Does android rescale skinned views sizes the same way it resizes the default ones? Also, if not, how can I handle the more than 5 display sizes using a background image and skinned buttons and scrollers (horizontal bar)?

How do you apply the background so that it displays in its entirety on each screen rather than across all 5 homescreens?

How do you guys like the physical buttons vs. the soft buttons (glass) on other phones? I've got an Incredible that I really like, but I'm having two issues that I'm not liking. Call quality and battery life. I looked at the Droid X and really didn't like the physical buttons. How many of you were disappointed by the physical buttons but have found them to be OK after using them?

I need my Android app to save it's state to disk when its activity is put in the background or killed. It's been suggested that I start a thread when onPause() is called and perform any expensive I/O procedures there (see http://stackoverflow.com/questions/3894668/saving-loading-document-state-quickly-and-robustly-for-image-editor).
In what situations will the OS kill the thread and how commonly do these situations occur?
I assume it will be like how Activities are dealt with where the OS can arbitrary decide to kill the thread but will mostly only do this when resources are extremely limited. It would be nice to find some specific documentation of this though.
From playing around, with some test code, a background thread started in onPause() will run indefinitely in the background on my device (I tried loading lots of apps and couldn't get it to be killed).
For my specific app, I'm writing a bitmap editor where I'm using the Command pattern and the Memento pattern to allow undo and redo of edits. I'd like the user to be able to undo/redo their edits even e.g. the user gets a phone call and the activity is killed when it is put in the background. The best solution I can think of is to use a background thread to constantly save my command and memento objects to disk during application use and to finish up saving any objects that are left in a background thread if onPause is called. In the worse case, if the thread is killed I'll only lose some edits.

My program does some network activity in a background thread. Before starting, it pops up a progress dialog. The dialog is dismissed on the handler.This all works fine, except when screen orientation changes while the dialog is up (and the background thread is going). At this point the app either crashes, or deadlocks, or gets into a weird stage where the app does not work at all until all the threads have been killed.How can I handle the screen orientation change gracefully?

I have a full screen dialog that has a relative layout that contains a TableLayout. Whenever the soft keyboard is displayed on the screen, it shrinks these buttons. Instead of filling the bottom of the screen, they only fill a third of it. How can I keep the size of the buttons the same similar to the Contact app?

I am using three buttons along with the list view.These three buttons are added to the layout using the TableLayout and TableRow.The first button takes more space on content, so the other two becomes smaller in size than first one. When the application runs, it doesn't even show the two other buttons.How can I make the size of three buttons equal and display all of them when application runs?Give me some example please.

I would like to know the way to make a user interface for Android for people that have low vision. The idea is to make a UI with the following features: 1- Uses very very big buttons. 2 -Uses very big font size. 3- Te colors to use are basically black and white (for more contrast). 4- The icons in this UI are not relevant. 5- We must sacrifice the number of chars that we can show in the screen to get bigger labels and buttons. 6- A simple zoom system for the images should be a great idea. 7- We can use the camera of the phone to get a magnifying glass. I'm member of a blind people association in Spain and we think that this should be a great idea for begining a new low-vision-user- interface that is not aviable in the market for the new mobile phones. This will help many people that uses movile phones but have many difficulties to work with them.

I designed the user interface of my app on the emulator and then I installed it on the Nexus one. For some reason the text boxes, labels buttons etc. have shrink in size. It looks as if the view has been zoomed out on the phone. If I arrange it correctly on the phone the objects don't fit on the emulator. Has anyone faced this? Is there some setting to have consistency between the look of the emulator and Nexus One.

I have an image that I want to place on the background on my activity. For the G1 I would use a background of 320x480 but with the nexus 1 the resolution is almost double that. Should I just place the large image and make the smaller phones size down? I am trying to keep the size of my package down as much as possible.

I'm trying to develop a very specific app for my Dell Streak. I want the entire app to run landscape. The Streak has a tilt function that switches the whole OS to a landscape 800x480.
So I want to make an ADT to test in that uses an 800x480 display, but whenever I set the size I get no buttons. The Streak has a Home, Menu and Back button aswell as volume/mute and power, and I need to use some of them for my application.
I'm not worried about the tilting messing up my application. Not yet, anyway. Just need the test environment the right size and with buttons.

I am a bit confused on creating an image which will be acting as a background for my activities. So, in short, my aim is that my application should be able to fit the different screen sizes. Therefore, what size in pixel should my three images be to be able to fill the screen of the device in ldpi, mdpi and hdpi?

I'd like to be able to use an image as my background in a relative layout, without it stretching. I don't want to just enter the images details into an XML file, as I want to use different images, with different sizes. I've tried the following, but it just stretches the images (I know the left, top, right and bottom variables have the wrong values, but I've just entered something into them, as a test to see if it makes any difference to the output, but it does not. If it did, I'd calculate the correct values programmaticly : -
RelativeLayout explosionlayout = (RelativeLayout) findViewById (R.id.explosionlayout);
imageAnim = (ImageView) findViewById(R.id.explosion);
Drawable d;
d = this.getResources().getDrawable(R.drawable.bomb);
int left = 10; int top = 10; int right = 20; int bottom = 20;
d.setBounds(left, top, right, bottom);
explosionlayout.setBackgroundDrawable(d);

I just bought Beautiful Widgets 3.0 off of App market and have been trying to add the Beautiful Home Weather widget on my home screen. However, no matter which weather skin I choose, the weather images are running off of the background on the bottom as if the background image is not long enough. I tried a few skins, but they all look the same. Is there an option I need to toggle or something?

seems pretty straightforward.
CODE:..............
But doesn't work!
It scrunches the layout background as the background to each button, I want it to span all three buttons...

I'm writing an application and I want one of my activities to have a background. I've read the android docs about supporting multiple resolutions etc. but my designer is asking me what size the wallpapers should be and I do not want a lot of images for low, normal, high dpi in all the screen sizes.
What would be the most space efficient way to get a nice screen filling graphic background on all those screens? Android is great and all, but I do not want to end up with a huge application since I need all sizes of images for everything.

I am not able to find out the perfect layout(viewgroup) to place four buttons as shown in the attached image. Basically, i want to place four buttons near the top/left/bottom/right edge of the screen. AbsoluteLayout helped, but it is deprecated (It is also better to avoid AbsoluteLayout as it is not very flexible for orientation changes)

So I'm loading images from a web service, but the size of the images are sometimes smaller or bigger than other images and the visualization looks silly when I put them in a ListView in android. I'd like to fix the size of my ImageView so that it only shows a portion of the image if it's larger than a preset amount. I've tried everything I can think of setting the setMaxWidth/setMaxHeight, setting the scale type to centerCrop, using ClipableDrawable wrapping my BitmapDrawable, setting using Drawable.setBounds(). I've tried setting in the XML and programmatically, but neither worked. I'm very surprised setting max width/height didn't do anything. Below is the XML I'm using ImageView definition in my layout file

I am currently developing a dictionary application with voice database. I would like to know about the current Android limitation on the file size. I am using a self-provided sqlite database ( > 50mb ) . I tested that once the built .apk size exceeds ~30mb the app will not be installed onto the simulator (INSTALL_FAILED_ INSUFFICIENT _STORAGE). Could anyone confirm me that if up until now there is no way to embed such large size files in a single apk ( Aimed to sell at Google Market without requiring user to download datafile afterwards). Also, is there a limitation of 1,048,576 bytes for a single file in the assets folder ?

if size of image is larger than or smaller than specified display size (on screen), then it is automatically, compressed and stretched resp by android run time or require to handle by explicitly.

Can somebody explain to me what makes up the installed application size? I have an apk that is about 8 MB, and often when I install I get the INSUFFICIENT_STORAGE error. I have around 25-30 MB free space on the phone. I'm doing debugging so I have to upload lots of new versions. If I uninstall the previous version then I can install the new version. The application manager claims that the app is taking up 22 MB. So back to the original question, how come the app is taking up 22 MB when it really only is 8 MB?

I would like to know why the size of my shared library .so is bigger than my .apk file generated with Eclipse? Approximatly the so size is twice the apk one. What is strange is after having installed it in the device (2.1 firmware) I checked the size of the apk when I uninstalled it from the device and surprisingly the apk size indicated is bigger even than the .so one. Is there any explaination of that?

I have touched on this question here, where Christopher gave an answer to this, but I dont really get it so I thought its time to make it a real question, not just a "follow up" =)
As it stands, the application Im writing has 4 different screens:
1. Screen 1 - list of nodes (main screen)
2. Screen 2 - options menu, tableLayout with buttons
3. Screen 3 - navigation
4. Screen 4 - text details on version etc
These screens can be navigated to/from using a "header" View that is placed on top. the header then has 4 different buttons:
+--------------------+
| menu with buttons |
+--------------------+
| |
| |
| |
| C O N T E N T |
| |
| |
| |
+--------------------+
The header is just an XML-file (header.xml) with a few buttons. That header.xml is the included in the Layouts using the include-markup. For example, the main.xml has the line:
<include layout="@layout/header"></include>
The header show up alright, but the question is - what is the correct approach to attach OnClickListeners for the buttons in the header?
Christopher pointed out that you could create an Activity class and do the hooks there, like this:
CODE:............
First, I cant make it work since the method setupHeaderButtons isnt accessible from FirstActivity.
Secondly, is this the right way to go at it?

My app downloads .png files to the sd card for later use. I kept getting OutOfMemoryErrors (if anyone could explain this too, that'd be great!) and so I took a look at the sizes of the images saved to the sd card, and they seem to be roughly double what they are on the server. Why is this, and how can I make them smaller?
public void onCreate(Bundle saved)
setContentView(R.layout.namedrxnscreen);
TextView t1 = (TextView)findViewById(R.id.rxn_text1);
TextView t2 = (TextView)findViewById(R.id.rxn_text2);
TextView t3 = (TextView)findViewById(R.id.rxn_text3);
TextView t4 = (TextView)findViewById(R.id.rxn_text4);
iv = (ImageView) findViewById(R.id.rxn_image);
pb = (ProgressBar) findViewById(R.id.rxn_loading);
vs = (ViewSwitcher) findViewById(R.id.rxn_switch);
