Jun 22, 2010Most of the time, Android scaling is nice but I have a case where I don't want any scaling and I can't find how to do this.
I made a simple layout to test code...

Android :: Set Center Of An ImageView Without Using Paddings / Disable Cropping Of Image?
Feb 11, 2009Is it possible to set the center of an ImageView without using paddings?
What I'm trying to do is, to place a part of an image outside the screen and animate it so that parts of the image become visible while other parts become unvisible.
Another problem is that when an image is bigger than the screen size it gets cropped. How can you disable cropping of the image?
And what kind of animation should be used? Should I go with RotateAnimation or is better to rotate the canvas ?
Android :: Imageview Ontop Of Another Imageview
Jun 15, 2010I have a listlayout with items in it that looks like this:
There is first an ImageView (the light) and then two textViews. All of this inside a TableLayout. (source here: http://code.google.com/p/switchctrl/source/browse/trunk/android/res/layout/device_switch.xml)
I want to have a rotating animation of a loading indicator Ontop of this light when this particular device (light) performs an action or an action is performed on it.
How do I put an animation ontop of this light imageview?
Android :: How To Fix Hit Area After Scaling?
May 11, 2010I am scaling the canvas of a linear layout on draw, but this throws off all the hit areas of my views inside of this layout. They respond as if there was no scaling taking place. What do I have to do to get themselves to re-register their hit areas?
View 4 Replies View RelatedAndroid :: Scaling Transparent Graphics In 2.0.1
Dec 13, 2009I have some transparent graphics in my game. Up through 2.0.0 they have looked fined. Since Android 2.0.1 though, some parts of the fully transparent regions of the graphics are instead slightly opaque (e.g. a circular gradient that goes to 100% transparency will have a faint halo around it).
I have tried putting my graphics in ../raw/ but that did not help (as described at http://developer.android.com/guide/topics/graphics/2d-graphics.html#d...)
I have also tried exporting the Adobe Illustrator graphics at 16-bit pngs (instead of 8bit), but that did not help either.
Android :: OpenGL Texture Scaling
Feb 18, 2010I have a texture with 8 equally sized stripes that I am using as a wall with OpenGL. On my Nexus One it scales it properly However, in emulators and on a G1 (and probably on other hardware), it does not scale properly, as the stripes remain the same width, while the height scales as it should. Is there an option that I need to set that is set to default on my nexus one but not on other platforms?
View 3 Replies View RelatedAndroid :: Nine Patch Pre-scaling On Hdpi
Jan 5, 2010I have some 9-patch images on my app, and they work great on the medium density. When I load the app on a High density emulator/device, these images look grainy. It happens only to 9-patch images. The others look great after the pre- scaling. Is there a way to make them look good after the scaling, like the non-9-patch images?
View 10 Replies View RelatedAndroid :: Avoid Scaling Of Background
Oct 15, 2010In a start activity of our android application we're using a linearlayout with an background image for whole space. The image size is 320x480 - the same as device resolution, we're using for testing. The problem is, the image will be scaled und looks not so nice. I tried to use imageview instead, but I've got black borders.
Some ideas, how to avoid scaling or how to get the proper size for background image?!
Android :: Scaling TextSize In A TextView?

View 2 Replies View RelatedAndroid :: Image Scaling By BitmapFactory.decodeResource()
Sep 17, 2009I can't wait to try out the new 1.6 goodies, but first I'm retargeting my existing applications, and I decided to start with Daisy Garden. Changing to android:targetSdkVersion="4" caused the application to segfault on startup and discovered that the BitmapFactory.decodeResource method now performs scaling based on screen density. In this case the behaviour is unwanted - I'm loading a set of masks that are scaled later during composition. So I've quickly inserted the following method, which seems to perfectly mimic the previous behaviour:
private Bitmap loadBitmap(int resId) { BitmapFactory.Options options = new BitmapFactory.Options(); options.inTargetDensity = 1; options.inDensity = 1; return BitmapFactory.decodeResource(context.getResources(), resId, options);
}
Android :: WebView Not Respecting Scaling Percentage
Jun 11, 2010I have a WebView which I'm trying to have scale to a certain percent on loading the page. The iPhone version of this software uses the HTML meta-tag:<meta name="viewport" content="width=320, initial-scale=0.95, maximum-scale=2.0, user-scalable=1">..Since Android's WebView doesn't seem to respect that tag I hard-coded the percent using setInitialScale(). However, the WebView is just flat-out ignoring this method call. No matter what number I put in there it shows at 100%.
View 5 Replies View RelatedAndroid :: Scaling Web Page In WebView Element
Nov 30, 2009I'm loading a URL into a WebView and I'm having difficulty setting the "scale" of the web-page. Specifically, the web-page is too big (800x600) for the screen, so my thought is to use "setInitialScale(50)" to reduce the size. Here is some sample code that doesn't work (i.e. the web-page doesn't scale to 50%)
WebView wv = (WebView)findViewById(R.id.webview);
wv.loadUrl("http://www.example.com/android/symptom");
wv.setInitialScale(50);
I also tried switching the order of the function calls but I get the same resultŠi.e.,
WebView wv = (WebView)findViewById(R.id.webview); wv.setInitialScale(50); wv.loadUrl("http://www.example.com/android/symptom");
As an alternative, I have tried to use the "zoomOut()" function like this:
WebView wv = (WebView)findViewById(R.id.webview);
wv.loadUrl("http://www.example.com/android/symptom"); wv.zoomOut();
This approach works for a split second, and then the image reverts to its original size.
Here is my content view:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/ android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent"> <WebView android:id="@+id/webview"
android:layout_width="fill_parent" android:layout_height="fill_parent" /> </LinearLayout>

View 3 Replies View RelatedAndroid :: High Quality Image Resizing / Scaling
Nov 17, 2010I need to scale down images coming from a Network stream without losing quality. I am aware of this solution Android: Strange out of memory issue but it is too coarse - inSampleSize is an integer and does not allow finer control over the resulting dimensions. That is, I need to scale images to specific h/w dimensions (and keeping aspect ratio). I dont mind having a DIY bicubic/lancoz algorithm in my code but I cant find any examples that would work on Android as they all rely on Java2D (JavaSE). EDIT: Ive attached a quick source. The original is 720x402 HD screen capture. Please ignore the top 2 thumbnails. The top large image is resized automatically by android (as part of layout) to about 130x72. It is nice and crisp. The bottom image is resized with API and has severe artifacting. Code...
View 1 Replies View RelatedAndroid :: Game Development Scaling - Texture And World
Jun 26, 2010We're looking for a method to properly scale our textures and world. The current method we're using is having an arbitrary world unit which calculates the screen resolution and receives the size of a pixel on all resolutions. However is there an easier way of implementing a scaling method for game development? We have looked through dip and other android native elements but these don't work as well for a larger scale on game development.
View 3 Replies View RelatedAndroid :: Scaling Game Images According To Display Sizes
Jan 6, 2010I developed a game with the g1 in my mind. Now I want to support large screen sizes but I don't want to add in the apk different images for different screen sizes because now the apk is 3mb and when installed thought market it became 6mb (due to protection on). If I have to double the images to support new screens, the apk would be too heavy (about 13mb, I think) so I'm wondering to know if scaling images at runtime by myself (without compatibility mode) maybe the best way for supporting larger screens. Compatibility mode does a great work in scaling images but it slows down drastically the frame rate (I think because the scale operation is made every time an image is used/moved and not only once on the load of the image itself).
View 7 Replies View RelatedAndroid :: Scaling - Animating Camera Preview Surface
Sep 20, 2010I am using android.hardware.Camera to get a preview and display it on a custom SurfaceView that implements SurfaceHolder.Callback.
I am trying to zoom in to the camera preview surface by a specified scale (not using the camera's digital zoom) but I can't seem to find a correct way to do it. I also need to be able to zoom out and scale down the preview.
I was hoping to be able to do this using a ScaleAnimation but it doesn't seem to work on SurfaceView, nor the FrameLayout containing the SurfaceView.
I also tried setting the size of the SurfaceView using setLayoutParams but that doesn't seem to work too well on various hardware and it would be tough to animate smoothly.
How to achieve this effect? Right now I am starting to think I might have to implement this using GLSurfaceView but I'm very unsure.
Android :: Scaling ImageButtons For Multiple Resolutions In Layout XML File?
Oct 4, 2010I have a button which I want to occupy 75% of the screen:
On a 480x800 resolution screen this would be 360 pixels wide.
On a 280x320 resolution screen this would be 210 pixels wide.
How do I go about specifying this in my layout XML file?
I understand there is a DIP unit of measurement, but does that also work to scale screen images for resolutions? What DIP measurement would I use for this, and do the images need to be saved at 160dpi.
Android :: VideoView Video Scaling - Different Screen Orientations And Devices
Aug 4, 2010How does Android handle scaling of a video being played within a VideoView?
So for example if I have a video that is say 480 X 270 (width and height), aspect ratio 16:9. And, say the VideoView is added to a LinearLayout with LayoutParams of (480, 270). What will be width and height of the rendered video in portrait orientation in a device that is 320 X 480? In landscape? In another device that is 320 X 550?
Android :: Force WVGA Droid Browser To Stop Scaling Images?
May 9, 2010I'm designing an HTML page for display in Android browsers. Consider this simple example page:
<html>
<head><title>Simple!</title>
</head>
<body>
<p><img src="http://sstatic.net/so/img/logo.png"></p>
</body>
</html>
It looks just fine on the standard HVGA phones (320x480), but on HDPI WVGA sizes (480x800 or 480x854) the built-in browser automatically scales the image up; it looks ugly.
I've read that I should be able to use this tag to force the browser to stop scaling my page:
<meta name="viewport" content="width=device-width; initial-scale=1.0; maximum-scale=1.0; minimum-scale=1.0; user-scalable=0;" />
... but all that does is disable user scaling (the zoom buttons disappear); it doesn't actually prevent the browser from scaling my image. Adjusting the scale factors (setting them all to 2.0 or 0.5) has no effect at all.
How can I force the WVGA browser to stop scaling my images?

Jun 6, 2012I have created an HTML5 'app' with a width and height 480 x 800 to be used as an android app.
Plan is that this can be scaled down/up for other Android devices to fit screen.
The app runs fine, but it is not being scaled to my device screen size. I have to scroll up/down and left/right on the every screen.
I have tried nearly every variation of the meta viewport tag with no succes (in the index.html file).
HTC Incredible :: Droid Incredible Browser Not Scaling Images
Aug 21, 2010I'm playing with a Droid Incredible my wife got from her company because I'm thinking of buying one.I do photography and I have a website.The images aren't huge maybe 600 x 800 pixels but that's bigger than the screen resolution of the Incredible so I can't view them on the built-in browser without panning around.A normal PC browser is smart enough to shrink the image to fit the browser window.Also, my wife's iPhone handles this with no problem. How do I get the browser on the Droid Incredible to do that?

But the text specified in android:text doesn't show up in my view.
Any thoughts on how to overlay text on top of an image?
There might be a simpler way to do this, so I'm open to alternative suggestions but I haven't been able to find anything via the google.
