Android :: Apply An Animation On A Drawable In Droid?

May 25, 2010

I am adding a glow animation effect to a logo. So far, I have managed to get the glow image behind the logo, using a LayeredDrawable, but I can't figure out how to animate it. I have found that AlphaAnimation would achieve the desired effect, but unfortunately I can only apply it on Views, not Drawables. How can I achieve this effect?

Android : Want To Create Empty Drawable In Droid?

Feb 10, 2010

Creating a Drawable that is completely empty seems like a common need, as a place holder, initial state, etc., but there doesn't seem to be a good way to do this... at least in XML. Several places refer to the system resource @android:drawable/empty but as far as I can tell (i.e., it's not in the reference docs, and aapt chokes saying that it can't find the resource) this doesn't exist. Is there a general way of referencing an empty Drawable, or do you end up creating a fake empty PNG for each project?

Android :: Many Image Files In Res / Drawable - Access In Droid?

Feb 11, 2010

I have to make a dedicated image viewer app for Android 2.x.

There are too many jpeg image files: about 2000~ jpegs, over 100MB.

I want access the image files with their file names,
but I couldn't find such an example.

By the way, is it okay to put many image files in /res/drawable folder?

I heard that the android application cannot be installed on sdcard and

the program repository is very small so 100MB app cannot be installed generally.

I found some examples which download the large data files on sdcard online,

but I cannot run a web server to host the data files,

and I must upload the fully packaged program on Android Market. (Should I build one apk file?)

What are the best practices for managing too many resource images (or something) in Android?

Android :: Define A Circle Shape In Droid Xml Drawable File

Jul 6, 2010

I have some problems finding the documentation of the definitions of shapes in XML for Android. I would like to define a simple circle filled with a solid color in an XML File to include it into my layout files.

Sadly the Documentation on android.com does not cover the XML attributes of the Shape classes. I think I should use an ArcShape to draw a circle but there is no explanation on how to set the size, the color, or the angle needed to make a circle out of an Arc.

Android :: Add XML Drawable In Eclipse

Oct 19, 2010

According to official documentation Google says that "Once you've defined your Drawable in XML, save the file in the res/drawable/ directory of your project." is the way to add a XML drawable to the project. But when I created the project ADT created 3 different drawable folders for mdpi, hdpi, and ldpi. So when I wanted to create my XML drawable, I right click on my drawable-hdpi folder and select "Add new Android XML file", and there I have to select what kind of XML file I want to create, but there isn't "drawable" to select. If I create new text file and save it as button_drawable.xml Eclipse says that there is an Error in the file and that It can't build my project.

Android :: Converting Canvas To Drawable?

Sep 5, 2009

Is it possible to convert a Canvas to Drawable?I may be really off in my solution, so if you have a better suggestion, please do tell me. This is what I'm trying to do.I'm trying to create a custom RadioButton. to set different states of the radio button, I need to use this parameter and one of the parameter to addState is Drawable. I know I can easily provide an image file and use it as a Drawable, but I want to do some image manipulation to the image before using it.There is a tutorial in ApiDemo called AlphaBitmap. It uses the onDraw method of a View to change a PNG file to full red and draw something with a gradient. So I customized it to shade an icon with gradient. So the problem now is that this is a View, and the View works perfectly fine if I add this View to the main view. But i want to convert this View to Drawable so I can use it as one of the parameter in addState. What I really want to achieve is to have different colour shades for different state of the RadioButton without providing different images to do so.

Android :: Organizing Res / Drawable Folder

Aug 10, 2010

My app has loads of images in the drawable folder, and I want to organize them into sub folders to make them more manageable. When I create a new folder, and move the images, they are no longer found (and not compiled into the R.java file). Can this be done, or do all my hundreds of images have to sit directly in the drawable folder?
