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 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'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);
Using theme or ImageView ?
View 2 Replies View RelatedMy goal is to develop a GUI application on top of a background image with buttons in specific places on the image. The first step is to display the background.
The image can be displayed with resources and is described in several FAQs including this one:
how-to-add-background-image-to-activity
It compiles and runs without errors, but the background is black. Here is the main.xml file:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout android:id="@+id/rootRL" xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/background">
</RelativeLayout>
The image has been in png, 9.png, and jpg format with basenames of 'main' and 'background'. It builds but does not display. Making clean and recompiling does not help.
This behavior occurs on both the emulator and on hardware -- an Atmel AT91SAM9M10-G45-EK. The SDK version is 2.0.1.
I have an activity which uses android:theme="@android:style/Theme.Dialog". The activity contains an ImageView which can show images of different dimensions. The ImageView should scale the Image so that it entirely fits into the window, at least on axes fits entirely and maintains the original aspect ratio. The size of the dialog should only be as large as the ImageView (plus its border width).
I tried the following but the dialog window always uses the whole available space:

I have an ImageView which I want to always be the same size. If the image is smaller than the view, I'd like it to be centred in the view. If the Image is larger than the view then I'd like it scaled down - with aspect ratio preserved.I've had several attempts at this myself
View 2 Replies View RelatedSo 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

This is the method from main activity. When onPause() is executed isRunningInBackground is set true.

startActivity(intent) had no effect (the activity didn't appear).

I am very new to Android (and Java) originally a C# developer.. and am struggling with the concepts and terminology.
I have been through almost all the tutorials and have decided to start on my first test app.The first part of my app is going to involve using the gallery widget (based on the hello gallery tutorial) to display a load of images. (these images will eventually come from the phones camera, but I will cross that bridge later!) My images are currently stored in the drawable folder in my project.As a first step I want to just have the user click on an image and it pops up full screen, just so I know how to get reference to it, but I am struggling. Evetually I want the user to click an image, then a window/activity(?) will open asking them for a bit of text. This will then be store in sqllite against the image. Code...
I 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>

What you need to add that the picture was of such size that I want?
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)?
View 2 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.
At 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:

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?
