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.

How can I access to any element (for example, change TextView's text) on FirstActivity from SecondActivity?
I want to include one button inside each row in a List Activity. When pressing one of these buttons it will be disabled and will perform a heavy task in the background (in a different thread to avoid screen blocking). After the action is completed the button will be enabled again and the row updated with some results obtained from that "heavy operation". Im filling my List with a custom SimpleCursorAdapter, its getView method calls super.getView and in the view (row) returned I access its button through findViewById and set my click listener (to disable it, and launch the heavy task in the background). Once this heavy task is finished I need a reference to this row view to find the button and re- enable it. SimpleCursorAdapter´s super.getView() reuses row views shown on screen to avoid creating many different rows instances, so when my "heavy task" is finished the row view reference i need to reenable its button may have been reused in a different row, so in the end I am modifying a button in a different row! I have tried different solutions, for example giving different ID to each row view (useless because it gets overwritten when the row view is reused) Obviously creating a different row instance for each row whether its shown on screen or not isnt the best solution.

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.
Ive set an in a running service a handler which does operation every X time. Now after certain time i wanna start an activity from that service, and in onCreate of the activity i wanna access that handler of the service(which started the acitivty) and stop it's schedualed operation

any idea how will i access the handler which is in the service? the service and the called activity are in the same proccess.
I would like to access the public method of an Activity run by a TabActivity using: Code...

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?
View 4 Replies View RelatedI'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?

View 2 Replies View RelatedI 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.

View 1 Replies View RelatedI'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.
View 2 Replies View RelatedI 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.
I need a textview with multiple drawables at bottom. In android, I know that there is a possibility of giving one image drawable for bottom. But i need multiple to be drawable at bottom.
View 2 Replies View RelatedWhen 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?
