How would I edit this tutorial so that it will grab images from the SD card? code...
Alternatively is it possible to make subfolders within R.drawable?

I have a small project in which I download images from Internet in the form of drawable and use them in Imageview for which I have provided functionality similar to an Imagebutton but without the gray edges. The question is that is there any functionality in Android (similar to IPhone) by which we can crop the drawable from edges to make them rounded edged drawable. Even if its a "not-tested-neither-recommended" method, do let me know. I would like to work on this a bit.

When i have an ImageButton and a drawable and i want to do something like the Drawer or Twitter where when i press the button and the corner of the image is highlighted over the edge, in drawer its yellow, in twitter its white. Like the one below.How do i set my drawable without using a lot of images?
View 1 Replies View RelatedAndroid framework has variety of icons and images - accessible as R.drawable.* - that can be used by applications for common tasks. Their names give some hint about what they are, but in many cases that's not sufficient. One has to use trial-n-error to find the right icon that fits one's purpose.
My question: Is there a way where I can preview all these images in one place, so that I can quickly decide which ones to use? I have looked inside android source code, but couldn't locate the root of these drawables.
I am presently using the following piece of code to load in images as drawable objects form a URL.
Drawable drawable_from_url(String url, String src_name) throws java.net.MalformedURLException, java.io.IOException { return Drawable.createFromStream(((java.io.InputStream)new java.net.URL(url).getContent()), src_name); }
This code works exactly as wanted, but there appears to be compatibility problems with it. In version 1.5, it throws a FileNotFoundException when I give it a URL. In 2.2, given the exact same URL, it works fine. The following URL is an sample input I am giving this function.

How would I load in images in a way that is compatible across the board from a URL?
I am getting an error from Eclipse when I use this xml file (res / drawable/btnswitch.xml) to designate different button conditions
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:drawable="@drawable/btn_st_rd" />
<!-- pressed --> <item android:state_focused="true"
android:drawable="@drawable/btn_st_gr" /> <!-- focused --> <item android:drawable="@drawable/btn_st_gr" /> <!-- default --> </selector>
I call it in my layout file with this code:
<Button android:id="@+id/startTimer_btn" android:src="@drawable/btnswitch"" android:layout_width="wrap_content" android:layout_height="fill_parent" />
Eclipse says it can't run the configuration because I have errors but does not show any errors. And when I remove the xml code (to go back to my original code which just sets a background image for the Button) it says that now has errors. I have to restart Eclipse to get the original code to run again.
I was working on Android 1.5, but now moved to the latest version. So there is only "drawable" folder in Android 1.5, but now There are 3 different folder for storing images in android project. And as i have found some articles for these 3 folders that
hdpi means High-dpi
mdpi means medium-dpi
ldpi means low-dpi
But still in confusion that what is the exact purpose of these 3 folders and when to use particular folder to store images in that?
I recently rebuilt my project to target 2.2 from 2.1. In the old project, I did not specify a target SDK (the manifest did not contain something like:
<uses-sdk android:minSdkVersion="8" />).
This gave me an error in the console when running, but everything worked fine so I didn't fool with it.
The new project now uses <uses-sdk android:minSdkVersion="8" /> in the manifest. But now my drawables from the /drawable-nodpi/ folder are loading with scaling, making them much smaller and significantly changing the desired visuals. If I cut out the <uses-sdk android:minSdkVersion="8" /> tag from my manifest, they load properly without scaling.
Even when loading my images like so:
BitmapFactory.Options opts = new BitmapFactory.Options();
opts.inScaled = false; Bitmap bm = BitmapFactory.decodeResource(_resources, resId, opts);
They are still scaled when I declare the minimum SDK in the manifest, but not scaled if I remove that tag. How can I load them without scaling while still declaring the minimum SDK?
I try to save a unique image to each object but I get this error, how should the constructor look for it to work that way? The constructor Beer(String, int, int) is undefined
m_beer = new ArrayList<Beer>();
final Beer b1 = new Beer("Tuborg", 7, R.drawable.tuborg);
final Beer b2 = new Beer("Carlsberg", 7, R.drawable.carlsberg);
final Beer b3 = new Beer("Urquel", 9, R.drawable.urquel);
public class Beer { //Members private String name;
private int color; //1 = Very dark 10 = Very light private R.drawable icon;
//Methods public Beer(String name, int color, R.drawable icon) {
this.name = name; this.color = color; this.icon = icon;
} public String getName() { return name;
} public void setName(String name) { this.name = name;
} public int getColor() { return this.color;
} public void setColor(int color) { this.color = color;
} public R.drawable getIcon() { return icon;
} }
I have some images (.png format) that I use as drawables on the surface of canvas in my android app. The problem I have is mspaint only allows a rectangular image file, so whatever I draw on the screen always shows up in a box. Is there a (free) program or way I can edit the png files so that when they are drawn on the surface of my canvas, they are drawn to shape?
View 1 Replies View RelatedCan I have sub-folders to hold my drawable resources. For example can I store an image in, say, 'res/drawable/content/images/myimage.jpg' and then find that resource via a call to:
id = context.getResources().getIdentifier("com.mycompany.myprog:drawable/ content/images/myimage", null, null);
I have tried this and it doesn't seem to be working (but I may have something wrong). Is it supposed to work or do all the resources need to be in the root drawable folder? Also, are jpeg files supported and drawable resources?
Are the images in android.R.drawable considered safe for third-party developers to use?
View 3 Replies View RelatedI am trying to move a set of images currently in the resources/drawable-hdpi folder to the Assets folder.
These images are copied to the private application directory when the app is installed.
When I do this the resulting image is smaller than when I had the image in the resources folder. i.e. the baked beans image is smaller than the others. If I load the baked beans images from the drawables folder it is the same size as the other product images.
I have tried to scale the image but it has no effect.
public View getView(int position, View convertView, ViewGroup parent)
{
ImageView imView = (ImageView)rowView.findViewById(R.id.product_thumb nail);
ImageView imProduct = (ImageView)rowView.findViewById(R.id.product_icon) ;
tvName.setText((CharSequence) values.get(position).getName());

View 2 Replies View RelatedI 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?
So I'm defining a class that sets a Drawable attribute in an object. The problem is that I can't access the getResource().getDrawable(int resourceId) method unless I have some Context.
So what I did was to send to that class an activity instance (let's call it "act") and then I did:
act.getResources().getDrawable(R.drawable.whellchair)
but, when executing that line it throws a NullPointerException.
When idea how to accomplish this?
I have a custom view on which i have drawn some lines(to represent a grid) i want to use it as a background to another view!!!
View 2 Replies View RelatedI have a GridView with a BaseAdapter that cycles through the elements making views for each element or cell in the grid.
What I would like to do is create a clickable image/button, and when the user clicks or touches it, for it to remain clicked and highlighted so that they make click on several if they so choose.
I have tried, ImageButtons, Buttons, ImageViews, LayerDrawables(with a swapable background color drawable), ToggleButtons, CheckBoxes, derived my own CompoundButton, but nothing seems to work.
I was a teeny bit successful with a ImageButton where I could create it selected, but if the user clicked on it, I couldn't get that visual state back.
I know how to put the icon on each tab, that is no problem. I also ran across this : Stack Overflow thread on pretty much same thing I followed one of the links from that question, and found this Pretty much, it said use a selector defined in the xml, sure, did that. But there is no id associated w/ it so I am not sure how to get the selector function as a drawable so I can use it as the icon for the tabs. Maybe I am going about this the wrong way.. But this is what I have, and obviously missing something.

I'm working on an android application, and I have a drawable that I'm loading up from a source image.On this image, I'd like to convert all of the white pixels to a different color, say blue, and then cache the resultant Drawable object so I can use it later.So for example say I have a 20x20 PNG file that has a white circle in the middle, and that everything outside the circle is transparent.What's the best way to turn that white circle blue and cache the results? Does the answer change if I want to use that source image to create several new Drawables (say blue, red, green, orange, etc)?I'm guessing that I'll want to use a ColorMatrix in some way, but I'm not sure how.
