Android :: How To Scale An Image In ImageView To Keep Aspect Ratio?

Mar 26, 2010

In android, I defined an ImageView's layoutWidth to be 'fill_parent' (which takes up the full width of the phone). My question is if the Image i put to ImageView is bigger than the layoutWidth, android will scale it, right? But what about the height? when android scale it, will it keeps the aspect ratio? What I find out is, there is some 'white space' at the top/bottom of the ImageView when android scales an image which is bigger than the ImageView. Is that true? If yes, how can I eliminate that white spaces?

General :: Change Aspect Ratio / Resolution On MK802 IIIS?

Apr 24, 2013

I want to use my MK802 IIIS with a projector but I am having aspect ratio/resolution issues. Namely my projector supports 800x600 and 1024x768 but on my Android stick I get chose 1920x1080, 1280x720 or 720x480 (Settings->Display->HDMI modes). The stick has only HDMI output and I am using a cheap chinese adapter to connect it to the projectors vga input. For example with 720x480 I do get the picture but at left side a slice of it is cut off.

Ideal would be if I could set the video output to 1024x768 (with 4:3 aspect ratio).So, how could I change it?

Is there any Xorg like solution, that is, add resolutions by editing some conf file?I should create a custom ROM, build custom firmware...

HTC Droid Eris :: Need Size / Resolution / Aspect Ratio For Contact Photos?

Jan 22, 2010

I'm wondering if anyone has figured out yet what the best resolution and/or aspect ratio is for custom contact photos? Most of my contact photos come from Facebook, but some I will edit on my PC and load onto the phone's SD card. I know there are issues with decent photos becoming low-res pixelated, so I'm wondering if I start with the best size and/or aspect ratio, maybe the phone won't have to resample the photos itself.

General :: Allwinner A20 Tv Box - Change Screen Res / DPI / Aspect Ratio - System GUI Always Stops

Mar 23, 2014

I have an Allwinner A20 tv box, I trying to use it on a device with an old, low res, 4:3, 5" screen. It works but I have a few problems - firstly the box has "pal" and ntsc" settings for use with AV out, but when connected the picture is squashed inwards so circles are represented as ovals. I ve tried to mod the aspect ratio/resolution but nothing works, the picture is always distorted.

On top of that everything is too small for the screen, it is readable but things really need to appear bigger, so I also played about with the dpi, this does make things bigger and a better match for the screen, even though the device doesnt actually have a screen itself.

I ve done both these mods with several apps and modding the build prop and I always get "sorry systemGUI has stopped", constantly - when you close it, it opens again straight away. Clearly settings doesnt like these mods, so I m trying to work what I need to change so it DOES accept them.

How I can successfully mod the setting.db and get this working at the correct aspect ratio and a dpi that is suitable for use on a low res screen ?

Android :: ImageView Pinch Zoom Scale Limits / Pan Bounds

Oct 7, 2010

I wanted to create an gallery with images.The images within the gallery should be zoomable and pannable. I could able to pinch-zoom an image but could not able to set zoom limitand prevent the image from being panned off the screen. I used the following code to zoom an image:http://code.google.com/p/4chan-image browser/source/browse/src/se/robertfoss/MultiTouch/TouchImageView.javaspec=svnd3e623ddeb6f9e97d9eba2c7aaa7c4567a3822b5&r=d3e623ddeb6f9e97d9eba2c7aaa7c4567a3822b5 First approach : I used TouchImageView to supply images to gallery, this allows me to pinch zoom but can't scroll the gallery. i.e I cant differentiate between 'single tab event' and 'tab to scroll event'

Android :: ImageView Scale Type Not Working In List Activity / Workaround It?

Apr 18, 2010

I have used ImageView's before and understand the different scale types that can be set... However I am having an incredibly difficult time trying to get an ImageView to scale properly in the row of a ListActivity or an ExpandableListActivity.

I have tried setting the android:scaleType property to every single value but the image never scales down. I have set the min and max sizes as well and they don't seem to have any effect. I have done both of these things in both the XMl and in code to no avail...

Does anyone have any ideas or perhaps a workaround? code...

Android : Preventing Scale On Bitmap Created In Execution Time For ImageView

Sep 23, 2010

I have a ImageView acting as a top banner on top of a webview. The image of this banner is created in execution time dependending on the resolution of the device. The height of the banner is always the same for each resolution. The only thing that changes is the width, which changes according to the orientation. But, since the width changes and the height doesn't, I end up having sort of 2 images with different proportion. And this is way the scale down/up won't work out for me.

Another problem is that everytime the user rotates the screen, the banner image is created again but Android seems not to update the image and thus I have a banner missing part of it.

I thought about having a real big image that will fit for both landscape and portrait orientation. But this seems not to be a good idea since Android keeps resizing the image everytime so it will fit on the space of the ImageView.

I'm running out of ideas here. Can someone suggest something?

Android :: Scale A Background Image Of A TextView For Droid?

Aug 13, 2010

I'm battling with extending a TextView for my Android app. I'd like to create "bubbles" to display text messages in a conversation, similar to the native iPhone SMS conversations.

Is there a way to implement the resizing of a background image without just stretching it? I'd like to have a single background image that keeps it's corners but get stretched only in defined areas. I think this should be possible because I've seen it in a SMS app, but I wonder how to implement that.

Android :: Scale Image To Maximum Size In Dialog-style Activity

Nov 24, 2010

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:

Android : Takes Drawable Object - Scale Image - Save Memory?

I need to know how he takes drawable object. I'm collecting some ImageView objects in array, they have background images that are rather big in resolution so they take lot of memory...

I have read somewhere that it will automatically create image with resolution that my imageView have, so i think it will take less memory than first one. Please tell me, if i set scaleType property, will it scale that image? Will that help me to save memory?

Android :: ImageView.setImageURI Scales Image

Feb 17, 2010

I have a view that I am drawing to a bitmap, saving to disk and then putting in an ImageView via setImageURI. However, when the image is displayed in the ImageView it is not being shown at the correct size. It is about 1/3 smaller than it should be. I'm guessing that this is a density issue, but I can't figure out what's going wrong (my emulator is WVGA).
