I am looking for an optimized solution to display image in different screen size. I have a image in server which I would like to display in different handled devices like iPhone, iPad ,Android based tablets or mobiles etc.

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.
View 2 Replies View RelatedI'm trying to get the real size of an image displayed in an image view. Actually my image is larger than the screen and the imageview is resizing the image to diplay it. I'm looking for this new size.I've tried to override the onDraw method of the ImageView in a custom view but I'm not getting the correct height and width.

View 2 Replies View RelatedI am trying to develop an app for which I want multiple screen support. I have read the Android article on Best practices for Multiple Screen Support. As per the article we have to follow 3 important things:
1. Mention support for different screen sizes (large, medium and small) and any density in AndroidManifest.xml.
2. Place images of 3 dpi's (120, 160, 240) in 3 folders res/ldpi, res/ mdpi and res/hdpi.
3. In layout's the dimension should be mentioned in "dip" units. Then Android will take care of the scaling on its own.
I have implemented all these points in my project. The images are picked up correctly from the appropriate folders. But the arrangements of the controls in not same. e.g. I ran the app on three emulators 1. Resolution 240*320 dpi 120. 2. Resolution 240*320 dpi 160. 3. Resolution 240*320 dpi 240. (All the emulator have same resolution but different density). The problem is the position of the controls is not same on all the three emulator. As per my understanding if the android:layout_marginLeft and android:layout_marginTop are mentioned in "dip" then this problem should not occur. As the density of the emulator increases the controls get placed more towards the right. Is it necessary that I provide layouts for all combinations of dimensions and density i.e. in layout-small, layout-large, layout- medium, layout-long,layout-notlong?

I am trying to display an image from a URL, which may be larger than the screen dimensions. I have it kind of working, but I would like it to scale to fit the screen, and I also have problems when the screen orientation changes. The image is tiny, and I would like it to scale its width to the screen as well. (In both cases, I would like the image to fill the screen width with scrollbars (if necessary for height).
Here is my ImageView:

Here is the java code which loads the image: (some error handling code removed for simplicity)

I have tried different settings for android:scaleType. I'm sorry if this question has been asked before. I've gone through a number of tutorials on the subject, but they don't seem to work for me. Not sure if it has anything to do with the way the image is loaded. (from the web instead of a local resource)
Another issue is that sometimes the image doesn't even load. There are no runtime errors, I just get nothing in the ImageView.
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
View 1 Replies View RelatedJust wondering if its possible to use the built in image viewer to display an image sourced from a database. I'm hoping I can pass the byte[] as an extra to the ACTION_VIEW intent, but can't find any docs on it so far. Alternatively I'll have to roll my own viewer or first write the image out to a file and pass that to the intent.

View 1 Replies View RelatedI have created a custom icon bar in Android using the XML layout creator, using a RadioGroup within a LinearLayout (XML included below). Each RadioButton within the RadioGroup has a custom drawable (with checked and unchecked states) as its android:button attribute. The Linear layout is itself within a RelativeLayout so that it can appear at an arbitrary position on the screen (as a side bar, in this instance).The drawables are 55 pixels wide, and the android:layout_width attribute of all these views is "wrap_content".When I make this component visible, aligned to the bottom-left of the screen, only about three-quarters of the RadioButton image widths are visible. Setting the layout_width of the RelativeLayout to "fill_parent" rectifies this and causes the full button to appear.However this means that the button group consumes click events across the entire width of the screen. How can I make the entire button appear, and have only the area of the button respond to clicks? Hard-coding the width of the drawable is not a particularly desirable solution.<RelativeLayout android:id="@+id/RelativeLayout01" android:layout_width ="wrap_content" android:layout_height="wrap_content"> <LinearLayout android:id="@+id/LinearLayout02" android:layout_width="wrap_content" android:layout_height="wrap_content" android:orientation="vertical" android:layout_alignParentBottom="true" android:layout_alignParentLeft="true" android:layout_below ="@+id/LinearLayout01" android:visibility="invisible"><RadioGroup android :id ="@+id/ RadioGroup01" android:layout_height="wrap_content" android:checkedButton="@+id/RB01" android:layout_width="fill_parent">
<RadioButton android:id="@+id/RB01" android:layout_width="fill_parent" android:layout_height="wrap_content" android:button="@drawable/DR01"/><RadioButton android:id="@+id/RB02" android:layout_width="fill_parent" android:layout_height="wrap_content" android:button="@drawable/DR02"/>
<RadioButton android:id="@+id/RB03" android:layout_width="fill_parent" android:layout_height="wrap_content" android:button="@drawable/DR03"/> <RadioButton android:id="@+id/RB04" android:layout_width="fill_parent" android:layout_height="wrap_content" android:button="@drawable/DR04"/> </RadioGroup></LinearLayout>

How to use this method to reduce or increase the picture?
What you need to add that the picture was of such size that I want?
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.

View 1 Replies View RelatedI 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?

View 1 Replies View RelatedMy application while compiled in 1.5 works fine. I had some memory issues w/ 1.6 due to image size, which was strange b/c the image size increased when taking photos by taking a picture w/ surfaceholder/imagecapture callback. I seem to have fixed re-displaying those images by resizing them using a bitmapfactory matrix. But my camera is now rotating everything 90 degrees. It appears that my Override of surfaceChanged does nothing, which is where I was setting rotation at 90 (I can't remember why, it was 10 months ago!). I have tried at rotating the camera parameters paramters at 90 degrees, 0 degrees.

View 2 Replies View RelatedI am running into a very weird thing. I have an ImageView, and when I call setImageURI with an image, it seems to change the size of the image view.
CODE:..............
The default image is 195 x 195, i am trying to set the image to be 200 x 200, after setting the image using setImageURI, i get the dimensions back and it says it's 48 x 48.
I have tried a bunch of different android:scaleType parameters, and I couldn't find anything that worked.
I also tried explicitly setting the size (layout_width="200px") and it seems to work.
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?
View 2 Replies View RelatedAt the moment I am attempting to set my camera on my Motorola Droid phone to take an image that matches the size of my screen (854 x 480 pixels), and I am attempting to accomplish via the parameters for the camera as such:

I have my activity implement the Camera.PictureCallback method of onPictureTaken (excluding log calls), so when the takePicture method is called it runs this method:
CODE:..........
For some reason though, my camera is taking pictures in 1280 x 960. Is this some sort of minimum size the camera can capture an image in? From log calls I can see that the Camera's parameters are still set to have a picture size of 854 x 480, but image keeps coming out as 1280 x 960. Am I decoding the image incorrectly, am I setting the camera's parameters incorrectly, or am I doing something else wrong?

View 3 Replies View RelatedI'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);

If there is a image on my phone that I want to send up to a server thats 1mb or higher I want to take that image and shrink it to a smaller size without messing with original image in anyway. I know how to get a from the phone and I also know how to send it up to a server, I just need to know how to make the image smaller because large files higher than 1mb are giving me issues.
