Android : ImageView SetImageURL Does Not Work / Way To Get?

Feb 23, 2010

I'm trying to do the following thing without success:

ImageView imgView=(ImageView)findViewById(R.id.imgView); Uri imgUri=Uri.parse("android.resource:// my.package.name/"+R.drawable.image); imageView.setImageURI(imgUri)

I'm stuck, because the imageView just shows nothing. how I can get an Uri (that I can use as ImageView source) from a local resource? which kind of Uri are accepted for the ImageView? IMHO, this topic lacks of documentation.

Android :: Why Would ImageView.setImageURI() Work In 2.2 But Not 2.1

Sep 15, 2010

I am displaying images and some text in a list view with an adapter. The images are pulled from the web, then cached locally and displayed. The images are already small (60px square), and I know their size, so I'm using the advice from here suggesting I use setImageURI instead of decoding the bitmap. The class that does the work is a modified version of Fedor's ImageLoader

The code attaches a stub drawable to the ImageView until the desired image is downloaded from the web, then loads the cached file from the sdcard. In Android 2.2 this works just fine. It's fast, and I don't get OOM crashes. On 2.1, though, I get the following error:

CODE:...............

The ImageLoader class is as follows:

Android :: ImageView In ListActivity

Jan 11, 2010

I 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?

Android :: Text On Top Of A ImageView

Nov 18, 2009

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.

Android :: Nullifying Imageview Src?

Apr 4, 2009

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

using CODE:..............

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...

Android :: ImageView With Graphic From The Www?

Feb 27, 2010

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 dont want to use WebView for this...

Android :: Zooming An ImageView?

Sep 11, 2010

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.)

Android :: Using ZoomControls With ImageView?

Mar 9, 2009

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?

Here is my code snippet:
