What's the default ScaleType of ImageView?If I put an image which is 400 pixels x 400 pixels on a normal screen (320x480) without specifying ScaleType, how will the image be scaled?

I need to resize several images inside ImageView to screen size. Currently I use scaleType="centerInside", it works good for bigger images to scale them down to screen size but doesn't expand small images.
All other suggested options crop or deform image. Is there any way to expand images (keeping ratio) via XML or do I have to do it manually in code?
I use Layout_width="fill_parent" and Layout_height="wrap content". If an image is bigger than the ImageView, it will be downscaled perfectly.
However, I never got it working to upscale smaller images. I tried any combination of ScaleType and "AdjustViewBounds": it always stays in its own size in the middle of the image view. Here is the code...
<LinearLayout
android:id="@+id/LinearLayout02"
android:layout_height="wrap_content"
android:background="@drawable/content_bg"
android:orientation="vertical"
android:padding="5dp"
android:layout_width="fill_parent"
android:layout_marginLeft="1px">
<ImageView
android:layout_height="wrap_content"
android:src="@drawable/test"
android:id="@+id/ImageViewTest"
android:layout_width="fill_parent"
android:adjustViewBounds="true"
android:scaleType="center"></ImageView>
</LinearLayout>
I 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?
I want to override the default android messaging application.
If I receive a sms or mms I want to send that to email but i don't want any notification on phone.
So basically I want to replace the default messaging application.
How can I make my application the default one that receive the sms?
I have installed Dolphin and like it, and I've made it my default browser, which is great. However, it is not only the system default, but it even opens links I click on in the Android provided browser (sometimes I both open). On your computer, when you click links in your non-default browser it doesn't send the links to the default one, and it shouldn't on this OS, either. Any ideas how to keep Dolphin as my system default browser, but not have it open links I click on in the Android web browser?
View 1 Replies View RelatedI am having custom Listview. Every row in listview contains image and textview.
After finishing the page I want to execute a thread which will get the reference of all the rows then will extract imgeview and set resource image as lazy loading image.
I just want to know how to get every row's image view so that I can set image resource in it.
Wasn't sure exactly how to ask this, but here we go So, for example, I installed "Dialer One", a dialer replacement.So whenever I hit the "Phone" button, it asks how I want to complete the action. Using Dialer One, or Phone. And it gives me the option to "Use by default for this action".So, lets say I want to use Dialer One by default, but then I change my mind. How do I set it back to the default Phone.Obviously, this question applies to more than just the phone app. After writing all that I think the simple way to ask my question is- I really just want to know how to undo the 'use by default for this action' choices I may make in the future.

Something like: onTouch.GetColorCode (from the pixel bellow my finger)

View 2 Replies View RelatedI have an ListActivity that I wan't to add a logo to at the top above the list but I'm unsuccessful. This is what my layout looks like at the moment.
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="fill_parent"> <ImageView android:id="@+id/logo" android:layout_width="fill_parent" android:layout_height="wrap_content" /> <ListView android:id="@android:id/list" android:layout_width="fill_parent" android:layout_height="fill_parent" android:drawSelectorOnTop="false"> </ListView> <TextView android:id="@+id/empty" android:layout_width="fill_parent" android:layout_height="fill_parent" android:text="@string/list_empty" /> </LinearLayout>
Then I add an drawable to the ImageView logo in onCreate. I've managed to show either the ListView or the ImageView but never both of them in the same LinearLayout. Is it possible to add other views together with a ListView?
Question on an oddity I am seeing.
I have an ImageView that I am using to display a splash screen for a couple of seconds:
CODE:..................
I'm using Android 1.6.
I'm wondering if there's a simple way to put text on top of an ImageView element. Specifically, I'd like to have text overlayed on top of a rectangle filled with a color gradient.
I have the following in my XML layout:
CODE:................
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.

I'm making a little card game in order to learn the more interesting stuff of the UI and I have a question:
I want to show 5 cards on the table, for that i have made 5 imageviews in the xml:
CODE:..................
As you might notice here, i'm doing them with an overlap since the uer should be able to pick up the last card and should therefore see it, but the other 4 are just so he'll know what was thrown lastly. my problem is: in the begining the imageviews have no src, but once i give them an image source

I dont know how i can undo it - i can't set the imageResourceId to null since it is an int type so is there something like -1 or some constant value that means null? i know about visibility, i'd rather not use it here unless i really have to, since it'll require a bunch or refactoring that i prefer to avoid...

I want to show a graphic inside my activity. A graphic thats from the www. Just like http://www.google.de/logos/olympics10-sskating-hp.png.
Wenn, in general I would download the graphic, convert it (maybe with photoshop or something), rename it (if neccassary) and copy it to my drawable folder. Then I can use its id inside my xml layout.
Now I want this procedure dynamically.
Which is the quickest way to do so?

I want to set the LayoutParams for an ImageView but cant seem to find out the proper way to do it.
I can only find documentation in the API for the various ViewGroups, but not an ImageView. Yet the ImageView seems to have this functionality.
This code doesn't work...myImageView.setLayoutParams(new ImageView.LayoutParams(30,30));
How do I do it?

View 2 Replies View RelatedI studied the Androidreference for hours now, but don't really get the clue how to draw something (Text, Bitmap, Path ....) on a ImageView.
Should I extend View and use the onDraw()-Method? If yes, how can I draw on my ImageView?
Or is there any other way to achieve my goal?
This should be easy, but I'm having trouble figuring out how to zoom an ImageView. I have an ImageView inside of a ScrollView and a HorizontalScrollView. I floated a ZoomControls over the ImageView and now I'm trying to figure out how to actually zoom the image.
I was thinking I would just scale the Drawable inside of the ImageView, but I can't figure out an easy way to do this.
How should I be going about displaying an image that I can both zoom and scroll?
And yes, I know about WebViews, but it seems wasteful to load an entire WebView just to display one image.)
I have a file called nochart.png in /drawable.
How can I set this to an ImageView?
chartImageView.setImageDrawable(R.drawable.nochart);
Does not compile.
When I use MapView in place of ImageView, there is no compilation error, but the app never launches on emulator. I followed the example given on android developer website.
When I use ImageView, it asks me to cast the ImageView object before getZoomControls(). But it is of no use.
Why zoomcontrols work with mapview well, but not with imageview? As zoomcontrols, mapview and imageview all are subclasses of view, I expected the example of mapview to work with imageview as well. Is there anything that I am missing?
How else do I use zoomcontrols with ImageView?

I want to display text on image view.
