Android :: Design ImageViews That Stretch According To Screen-size?
Nov 8, 2010
I have a requirement where few of my image views form border areas of an application, the application will be running on many screen sizes.
I'll be creating a uniform image for the smallest size possible, which can be repeated as many times as needed, and still presents the same image.
i want the image view to replicate the image contained whenever it is increased.
Perhaps I was able to describe my problem.
Is anything like this possible?
I tried 9-patch images, but I couldn't find nice articles on it which could explain how to create useful images with it which could suite my need.

I want to download an image (of unknown size, but which is always roughly square) and display it so that it fills the screen horizontally, and stretches vertically to maintain the aspect ratio of the image, on any screen size. Here is my (non-working) code. It stretches the image horizontally, but not vertically, so it is squashed. Code...

I thought I have understood the XML layout of Android, but it seems that I haven't. I want to have four ImageViews on one screen, to view four images at the same time.
It should look like this, where A to D represents the image views:
DDDAAA
DDDAAA
BBBCCC
BBBCCC
How can I do that? I tried it this way, but it's not working. The Eclipse Editor seems not to be very good for this either. Is there a better one to create those layouts?

I fight with me for some days about asking this question.
Its pretty plain and simple:
If you have an application with a GUI totally working on 2D drawing, what should be the best practice to handle what to draw and where to touch?!
Some example for better understanding:
I have a game with a map. On this map I can build houses and stuff.
I also have a information bar which can be extended. On the extended bar I draw some information about the game and also enables to change different values. If a touch occurs, I have to check, if the information bar is extended or not to determine if I want to change something on the map or something on the bar.
Thats done by the State Pattern, but I have some doubt if thats the right one because I think it can be a bit complex because of possible "sub-states".
So basically the question: Is the State Pattern (from GoF) the best practice to handle a pure graphical GUI?

I am designing a home screen widget. I ran this widget on a HTC Hero device, which has a screen of 320 pixels * 480 pixels with mdpi. It ran perfect on HTC Hero. The widget takes 3 cells * 2 cells space, i.e. 240 pixels * 200 pixels.Then I ran this widget on a Nexus One device, which has a screen of 480 pixels * 800 pixels, mdpi. Since Nexus One also is mdpi, so I though 240dip is equivalent to 240 pixels on Nexus One and 200dip is equivalent to 200 pixels on Nexus One, so the widget will not take 3 cells * 2 cells space on Nexus One device. To my surprise, when running on Nexus One device, the widget take exact 3 cells * 2 cells, about 360 pixels * 300 pixels, on Nexus One device.I am confused. The layout xml above specifies 240dip in width and 200dip in height for the widget, but why did it take 360 pixels * 300 pixels on Nexus One Device? What am I missing?

I'm a web designer by nature, accustomed to changing resolutions and font sizes, but I'm unsure how to design for the Android platform without knowledge of screen sizes, especially when the screen rotates from portrait mode to landscape.
Should I just do generic things that tile, or is there a way to design things of static size?
By this, I mean for the GUI and graphics, not element nodes of the XML.

I am displaying a table of values in my android application, and would like the columns to be distributed evenly in terms of size , instead of sizing according to content. Been playing around with stretchColumns but couldn't manage to figure out the right combination.

I'm trying to figure out how to animate in and out of Imageviews.
Basically I have a LinearLayout with an ImageView and a Button at the bottom. Everytime the button is pressed, onClick() is invoked and I do
image.setImageResource(imageArray[imageCounter]);
I simply change the image displayed on the ImageView by selecting different photos in the @drawable.
Now I want to put an animation when these imageviews are changed (when button pressed). I used
inAnimation = AnimationUtils.makeInAnimation(this,true);and in onClick() I do image.setImageResource(imageArray[imageCounter]); image.startAnimation(inAnimation);
This works fine too. The new image comes to the screen animated. But how can put an out animation too? It seems only one animation can be assigned with startAnimation().
What is the best way to animate an imageview OUT and then animate another imageview IN? Because I want to change the animation depending on the button pressed, I cannot use ViewFlipper. For example, if I press button_Anim1, current image will slideout from right and the new image will fade in. But if I press button_Anim2, current image will slideout from top and the new image will slidein from left. And so on.
I see that I cannot use two different image.startAnimation() in the onClick() method to make the current image View.INVISIBLE and then make the new image View.VISIBLE.

From Android widget screen guidelines,we know that, home screen has 4*4 cells, and in portrait orientation, each cell is 80 pixels wide by 100 pixels tall. I think these are for baseline HVGA screen. How about for large screens and hdpi screens, do they still have 4*4 cells for widget and each cell in portrait orientation is still 80 pixels * 100 pixels?

I need help coming up with a way of executing the following sequence using some type of view or layout combination in Android:I have 3 image objects... say object A, B, and C...I have tried every combination of Threads, AsyncTasks, Handlers, custom layouts, AnimationListeners, etc. but everything I've tried has failed.
If only the ViewSwitcher could take more than 2 views.

since I have updated my project (http://code.google.com/p/ bestcardgameever-android/) to the 1.5SDK, I need to switch the deprecated AbsoluteLayout with something else. The problem is the project is a card game that has cards showing and some of them need to be overlapping (take a look at this note the cards in the center) I could really use a tip on how to do this with a FrameLayoutetc.

I want to load bitmaps into ImageViews in Android, but I don't want to use the R.drawable syntax because I have a lot of images with a standard naming convention so it's much easier to get the image with some logic. For example, all my images are named:
img1.png
img2.png
img3.png
So if a user selects a value, let's say x, I show "img" + x + ".png" in the ImageView. Looks like Bitmap.decodeFile is what I need, but I need to know the syntax of how to get to my drawables folder since that's where the images are. Or if there's perhaps a better way.
I realize I could do this with a switch statement instead of concatenating the image name but that would be a lot of lines since I have so many images.

Im messing with imageviews and I am able to align a single imageview in the center horizontally with android:layout_centerHorizontal="true"
Now my main problem is that I have X imageviews and when I align them all like that, and then use the android:layout_toRightOf="", they just start from the middle.

I need to load several ImageViews into a layout. The ImageViews are used to show a rating using 'star' icons. The number of stars (i.e. the rating is determined during loading by reading a configuration file.
The ImageViews are sitting inside a RelativeLayout layout.
Currently I am using something like this:
CODE:........
My quesions are:
1) Is doing the loading dynamically (not using an xml) is the 'right' way of doing this ?
2) If it is, how do I make the stars display in a line, currently they get placed one on top of the other.

I'm just starting to get the hang of animations, tweened animations that is. I have made several imageviews with pictures rotating and moving, and its all very fun, but I don't know what the best approach for doing multiple animations is.
For example I created a LinearLayout and stuck some ImageViews in it and wrote this:
CODE:...............
for each imageview. So they all spin. But now I want to step it up a gear. But reaidng other sources on the net it seems some people use canvas to do animations. What is the best way?

I got to know that the devices with screen resolution 1280x720 or 720x1280 are extra large screen devices.
But when I run my application on Samsung Galaxy S3 SGH-T999 (resolution 720x1280) throught eclipse, the following code prints "Normal screen" i.e. it is a normal screen device but according to my knowledge it should print "Extra Large screen". If its a normal screen size device actually then why its picking the layout (XML) file from res/layout-xlarge-port folder instead of res/layout? Need to understand this screen size concept so that I can make my application for multiple screen sizes.
// get and check the screen size of the device
int screenSize = getResources().getConfiguration().screenLayout &
Configuration.SCREENLAYOUT_SIZE_MASK;
switch(screenSize) {
case Configuration.SCREENLAYOUT_SIZE_XLARGE:
Toast.makeText(this, "Extra Large screen",Toast.LENGTH_LONG).show();
break;
[code]...
