Android :: How To Reference Drawables Delivered With Android In XML
Sep 4, 2009
I'm defining my options menu in an XML file and I want to add an icon to the menu items. Normally, this would be sth like -- < (...) android:icon="@drawable/iconfile" />.But I want to use the drawables that are already stored in the android.jar (as listed here: http://www.screaming As the website says, I can access them via -- myMenuItem.setIcon(android.R.drawable.ic_menu_save); But how can I do that in XML? I tried several things but none worked for me.

Is there a way for the sender of a Notification to know when that Notification is delivered to the receiver? i.e. Some method that can check if a the user has clicked on a given Notification.What I'm trying to accomplish is this: Have my Service send a notification with a PendingIntent to start ActivityA. But if the user starts ActivityA without clicking on the Notification, I would like the service to cancel the Notification and send a direct Intent to ActivityA

Is there a way to extend a drawable (just like how shapes work, create your own tag) and allow it to be inflated from XML? Or is drawable only for the allowed 9 types?

I want to take a byte and append it to a resource ID to be able to get the image that corresponds to that numbered deck in the game. It was easy to with paths on other devices, but with the Resource ID's I am unsure how I could go about do this.
Here's what I have now:
CODE:..................
In my Blackberry version of this, I simply had:

Is there a way to accomplish something similar using Resource IDs on Android?

Im developing an app which is a product catalogue. Users can search for and view products (books). It's all read only and just so allow user's to view products. When the user clicks on a product, the next screen displays
- book title
- book author
- picture of front cover.
It's the picture part that I've a question about. I know one way to present drawables is to have them in the "drawable" direction in my android project and access them (in my xml file) as android:src="@drawable/name".
Only problem is that new products will be added so I can't store drawables in the APK file when I release it. I'll need to read them at runtime. I'm wondering what the best way to approach this is.
I'm thinking of upon app launch executing an AsyncTask which would call
openConnection of HttpURLConnection and would grab down all drawable(from a particular remote directory on a website) and would then store them in the sqllite db (as a blob). Each product in the db could easily be associated with it's specific drawable.
Not sure if there's a better approach to this ? or should I save them to the internal storage of the device (I know the size is an issue with this option). Or I could, when I show the product, call the Async task to present the image - i.e.get the image when the user requests it. This sounds good.

I am using a SurfaceView, and wish to animate Drawables. All the animation tutorials I have seen concern using an ImageView, which as I understand is not a sensible approach from within a SurfaceView. Does anyone have any suggestions for doing frame-by-frame animation within a SurfaceView? Can it be done with openGL?

I'm trying to draw a "gauge" on the screen with information from various sensors. I have a class that extends Drawable and a custom view that during construction creates a new AnimationDrawable and sets the only frame to my custom Drawable. I then start the AnimationDrawable from my Activity onWindowFocusChanged method. My custom Drawable onDraw method is only called once though. Is that by design (as in onDraw is called for each frame once and it's cached and shown over and over) or am I doing something wrong?

I want to use a number of ShapeDrawables in my application, which are all similar, but with different colours etc. Obviously I could just define them all in separate xml files, but is there a more efficient way to have one xml definition, instantiate various objects and change the colour either in code or xml? You could perhaps do this by calling mutate() on one ShapeDrawable defined in xml, but this returns a Drawable, rather than a shape drawable.

How do access a drawable which resides in my project's res/drawable folder from outside an activity? The component which handles the loading of images is generic and is not inside any activity. I would like to display an image from res/drawable in case it can't be fetched from the web.

I'm trying to create an appwidget with a customizable background. I use a NinePatchDrawable and I would like to change it's color (using the setColorFilter method). This is no problem in an Activity, but it does dot seem possible with the RemoteView object used for appwidgets.Is there some way to get an ImageView in an appwidget to be updated with a new Drawable, not a Bitmap?Or if not, perhaps it's possible to get the actual size of the appwidget and convert / save the colored NinePatchDrawable to a Bitmap and then update the ImageView with that?I already searched quite a bit for a solution, but haven't found anything so far. I hope it's not impossible.

I am using some drawable objects, when I instance them and paint in my canvas they doesn't get the original PNG image file size, instead they get a bigger size, so they does't paint in my canvas as I expected since I wanted them in their original sizes, why this happens?
(original file is 96x96 pixels)
mSprite = mRes.getDrawable(R.drawable.my_sprite);
mSpriteWidth = mSprite.getIntrinsicWidth();
// It returns 114, not 96 mSpriteHeight = mSprite.getIntrinsicHeight();
// It returns 114, not 96
mSprite.setBounds(coordX, coordY, coordX + mSpriteWidth, coordY + mSpriteHeight); mSprite_PipeRect.draw(canvas); //It paints at 114x114 size, it shows bigger in the screen then original size.
Something similar happens with the background but it is fixed in the "setSurfaceSize" event this way:
public void setSurfaceSize(int width, int height) {
mBackgroundImage = Bitmap.createScaledBitmap(mBackgroundImage, width, height, true);
}

I am working with a library of maps which paints the icons on the map using drawables and canvas. Now, i'm trying to modify it in order to the user can click on icons. So i want to attach drawables into different ImageView with a onClickListener. However, i don't know how i can paint the ImageView using canvas from method onDraw.
I've tried with:
ImageView iv = new ImageView(context);
iv.setDrawableResource(drawable);
iv.draw(c)
But it doesn't appears in screen.

When creating a stateful drawable, I cannot find the other drawables (9-patch images) that are there - i get no "suggestions" ("intelliSense").
But if I try to find drawables in another XML-file there is no problem.
This is my stateful drawable
CODE:..............
The "view_background_pressed" etc are all there, and they can be found in other XML-files but not in the statefule drawable.

When I add drawable resources to my project they do not show up in the list of drawables in the Reference Chooser. I checked the R file and there are references for the files.
I have tried refreshing the project, cleaning the project, and fixing project properties and nothing seems to help. Sometimes a couple will randomly show up in there, but not all of them.
The only consistent way I can get them to show up is to restart Eclipse.
Further findings:
After some trials, I found an other inconvenient work around to he issue. Turns out when importing multiple files into the project at once, Eclipse will only add the last one imported into the reference chooser. So when I imported my images one at a time, they all show up properly!
Like I said, inconvenient considering the amount of images I have left to import, but maybe with this new information it may help nail down where the issue may be and a possible fix.

I would like to display all resource drawables in a list so that the user can select one. Is there any way to loop through all R.drawable items so I don't have to hard code them into my program?

What is the best approach when using default Android drawables? Should I use android.R.drawable or should I copy the drawables in my project and use R.drawable?
Is there any risk, that in a newer version of Android, some of the default drawables are removed or resized? Or, affect in some negative way, the look of my app? Also, which of the drawables in the Android source code are considered "stable" and should be relied on?
I'd rather not copy the drawables because I think that the look of the app should be consistent with the Android version used. So, for example, for version 1.6 it should use the default Android bitmaps for version 1.6.

I am trying to modify this example:
http://developer.android.com/resources/tutorials/views/hello-gridview.html
But instead of displaying images that are resources, I want to display Drawables that I currently am storing in a List.
Can anyone instruct me on how I would modify
code...
To display my drawable items instead?

I'm writing an app that shows in google maps pipes and valves(lines and points). For that i've two classes.
One extends from ItemizedOverlay, and i add to map overlay one for each category of valve, and each one can have more than one item.
The second extends from Overlay, and in the draw method y draw the line with the method drawline of the canvas.
The problem i've is that the lines are drawn over the ItemizedOverlay items, no matter the order i add them to the mapView.getOverlays().
I want the lines on the bottom of all overlays. is there a way to do that.

Dear 2.2 Sense users, I am very much interested to know whether the updated OS brings respite to the most frustrating issues of my present software system
1) Do sms reports work well? Is there an option for notification when a message is delivered? Is the delivery report icon next to the message different when undelivered and delivered?
2) Can vCards sent via SMS be imported into the contact book easily? Does the import function really work?
3) Changing a contact's Display name: The same contact may have different names for different accounts, such as his face book profile, google profile, and how I've saved it in my phone. I know I can select any one of these to be displayed in my people app and for dialing, but does it stay that way? Presently the name keeps changing back to default and it's so damn frustrating.
4) Do face book profile pics in the contacts update on their own while syncing?
5) Can I change the password of my face book and gmail account in the phone's account settings?
6) Does the notification LED blink continuously if there's a notification, rather than give up after a few minutes?
7) Has shutdown speed improved?

Apparently the ERIS does not have a "delivered" for SMS. On my BB (for VZW to VZW) a "D" would appear when the SMS was received at the other end.

so just to clarify, this isn't another one of those "Why doesn't my message show as delivered?" threads. I already know it CAN be done, I found that out accidentally. It worked once, but I don't know how to make it work again.What I did when it worked: I sent my sister a message and then quickly switched over to iheartradio. Her message wasn't sending and the station was stuck at connecting, so I power cycled the phone. Then the message sent and to the right of it there's a green circle with a check mark. If I touch that, it says "Report" and then the receiver's name and "Status: Received." So,does this only work when there's an error to begin with or what?!

I've tried searching up the forums and found that some people had this bug and it was fixed by doing the *228 option 2. I tried that and when I use Handcent it still says the message is not delivered and sometimes it just flat out sends a blank message.The text is going to an email not an actual phone number but I'd like to keep handcent because I really like the pop up and the GUI. Would anyone have any other tips or tricks to help me get rid of this annoying error?Well i guess I forgot to mention some things.I updated my phone to 2.1 last night with the "new" leak I guess you call it.I tried restarting my phone, uninstalling and reinstalling handcent.

I downloaded Handcent from the Android market. This is a great application for sending sms's and mms's, but when I send a message it is delivered twice. That is because the default message application is still installed on the phone and the message is therefor automatically send through Handcent and the default message app. Can I delete the default message app from my phone without corrupting the software on the phone? I don't want to implement the factory reset on my phone, have too many apps that I don't want to loose or reinstall.
