Android :: Dynamically Get Drawables By ID

Mar 10, 2010

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?

Android :: Inflating Drawables From XML

Aug 23, 2010

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?

Remote Drawables In Android 4.0.3?

Sep 23, 2012

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.

Android :: Animating Drawables From Within SurfaceView

May 19, 2009

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?

Android :: AnimationDrawable With Custom Drawables

Jul 25, 2009

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?

Android :: Multiple Drawables From One Xml File

Aug 15, 2010

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.

Android :: AppWidget Updating ImageView With Drawables?

Nov 7, 2010

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.

Android :: Getting Wrong Sizes With Drawables Objects

Sep 17, 2010

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);
}

Android :: Stateful Drawable Not Finding Other Drawables

Jan 5, 2010

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.

Android :: Refresh List Of Drawables In Eclipse?

Mar 7, 2010

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.

Android :: Use Default Droid Drawables / Risk To Remove Or Resize It?

Jul 8, 2010

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.

Android :: How To Update Widget Dynamically?

May 28, 2010

I am currently learning about widgets in Android. I want to create a WIFI widget that will display the SSID, the RSSI (Signal) level. But I also want to be able to send it data from a service I am running that calculates the Quality of Sound over wifi. Here is what I have after some reading and a quick tutorial: public class WlanWidget extends AppWidget Provider {RemoteViews remoteViews; AppWidgetManager appWidgetManager; Component Name thisWidget; WifiManager wifiManager; public void onUpdate(Context context, AppWidgetManager appWidget Manager, int[] appWidgetIds) { timer timer = new Timer(); timer.schedule AtFixed Rate(new WlanTimer(context, appWidgetManager), 1, 10000); The above seems to work ok, it updates the SSID on the widget every 10 seconds. However what is the most efficent way to get the information from my service that will be already running to update periodically on my widget? Also is there a better approach to updating the the widget rather than using a timer and timertask?
