I have seen that the ImageView.setImageBitmap() can process high resolution images(even of size greater than 480x640), but RemoteView.setImageViewBitmap() fails with FAILED BINDER TRANSCATION error !!!!
Is there ary constraint on the bitmap size which RemoteView can handle ???? Why is the difference in the behaviour ?

From the javadoc of RemoteView, it said " * A class that describes a view hierarchy that can be displayed in another process."
But unlike View class, RemoteView does not have a 'draw(Canvas canvas)' method. Can you please tell me which method of RemoteView causing its layout to be drawn on screen?
I am not sure why this is not working and I can not find any answers here or after an extensive Google search. I have an app widget and I'd like to add views, (textview, etc.,) to the remoteview but it never shows up.
Here's the code:
CODE:......
This is what I ended up doing:
CODE:...................
Doing "edu.sju.BlackJack" Is not causing updates that are later called to occur. I reference the layout correctly and the calls that are supposed to update it are correct, so what do I put in for the package name?
I should add that my package name according to the manifest is the above. This is the code I have now which currently doesn't update the screen (or i'm guessing change the value correctly). RemoteViews name = new RemoteViews("edu.sju.BlackJack", R.layout.play_screen);
If that's not it.. would it then be this code? name.setTextViewText(R.id.Dealer_Total, "0");
Dealer_Total is the id for the TextView that I want to change.. however again the Change is not occurring.
Here is the whole of my code that i'm talking about, first Playscreen.java

More buttons go here (if any)

Over the past few days I have been trying to implement custom widget functionality. In this case I have instantiated a RemoteView containing some TextViews and an ImageView in one application's BroadcastReceiver. The BroadcastReceiver receives the intent signaling it to send the RemoteView to the calling application. When the calling application receives this RemoteView it uses apply to inflate the view properly and display it on the screen.
The problem occurs when the activity changes, the inflated RemoteView occasionally has information disappear. One time the image even changed into another image from a drawable located in the BroadcastReceiver's application. Has anyone else experienced a similar problem and/or have a solution?
I have looked at posts concerning ImageViews in widget use and orientation changes. Is this problem related? I am not entirely sure. I am currently running Android 1.5 SDK and am not able to upgrade for this side project of mine.
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 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.
So here is my question. I am trying to use an online thumbnail. I can have looked around and have not found too much data on this. Can some provide me the simplest way to do this. Also If i implement a simpleExpandableListAdapter which is designed as a textView Adapter is there a way to force the image in?

how can I implement an imageview that has touch-sensitive hotspots so that when the user touches one, a dialog or something similar appears.
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:

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?

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?
