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.

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?

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 using eclipse for Android development, and the editor always seems to take a while to actually update and recognize if I change an ID in a layout, then try to use it in a class with R.id.someId. Is there a way to force a refresh?

Just my a new Android phone and I've been tinkering with some basic apps. It's been driving my crazy that the Android plugin for Eclipse refreshes externals folders whenever I save ANYTHING. Normally I wouldn't mind but when it takes 10s to refresh I start to notice. I already searched and other people have this problem, but there are no solutions. If it matters, Eclipse 3.5 running on a 64bit jvm on Ubuntu 9.10

What is the best way to display a database queries results on the screen using ListActivity? I need the db queries to run in the background and I also need to be able to make different queries and refresh the screen according to the query result. I am using the ListActivity class with a SimpleCursorAdapter in order to display the db queries result on the screen. At the moment, I am doing the db queries at the background using AsyncTask, when getting the results I want the list to be updated immediately, but I can't find a good way to do it. It worked only when I used the changeCursor(cursor) function to set the adapter to a new cursor with the new results. But I don't think this is a good solution since it seems to stuck the UI for a while. I also found some posts about notifyDataSetChanged() but I am not sure if/how/when I should be using it with a SimpleCursorAdapter to make the view refresh.

Currently I am working on IM, and I am facing problem during implementations. I am implementing this messenger using XMPP client and using smack API for implementing all features like contacts list, online offline status, and chat also. Prblem which I am facing:
Its my list view where I am showing contacts list
public class ContactsList extends ListActivity implements OnClickListener{
@Override protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
ContactsManager manager = new ContactsManager(this); setListAdapter(manager);
} public class ContactsManager extends BaseAdapter{
private LayoutInflater mInflater; private Bitmap mainListIcons[];
private static ContactsInfo contactsInfo; public ContactsManager(Context context) {
mInflater = LayoutInflater.from(context); mainListIcons= new Bitmap[3];
mainListIcons[0] = BitmapFactory.decodeResource (context.getResources(), R.drawable.online);
mainListIcons[1] = BitmapFactory.decodeResource (context.getResources(), R.drawable.offline);
} @Override public int getCount() { return Global.contacts.size();//
contacts is vector where I am saving my contacts
} public Object getItem(int position) { return position;
} public long getItemId(int position) { return position;
} public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder; if (convertView == null) {
convertView = mInflater.inflate (R.layout.main_settings_lists_icon_text, null);
holder = new ViewHolder(); holder.mainListDisplayText = (TextView) convertView.findViewById(R.id.main_settings_lists_text);
holder.mainListDisplayIcon = (ImageView) convertView.findViewById(R.id.main_settings_lists_icon);
convertView.setTag(holder);}else{ holder = (ViewHolder) convertView.getTag();
} contactsInfo = (ContactsInfo)Global.contacts.elementAt (position);
String username = contactsInfo.getUsername(); String status = contactsInfo.getUserstatus();
if(status.equalsIgnoreCase("unavailable")) { older.mainListDisplayIcon.setImageBitmap(mainListIcons[1]);
}else{ holder.mainListDisplayIcon.setImageBitmap(mainListIcons[0]);
} holder.mainListDisplayText.setText(username); return convertView;
} static class ViewHolder { TextView mainListDisplayText;
ImageView mainListDisplayIcon;}
public class ContactsHandler implements RosterListener {
@Override public void entriesAdded(Collection<String> c) {
for(String s:c) { Log.i("ADDED Contacts",s);
} } @Override public void presenceChanged(Presence p) {
Log.i("PRESENCE",p.getFrom()); Log.i("IS Available",""+p.isAvailable());
Log.i("UserStatus",""+p.getStatus()); if(p.getFrom().contains("@") && p.isAvailable())
{ ChatManager chatmanager = Connection.getVopConnection getXMPPConnection().getChatManager();
Chat newChat = chatmanager.createChat("gulfam@imran-mehmood", new ChatHandler());
} } }

I have had this problem for a while but never tried to fix it but now discovered it is not only on my GNex but also my Tab 2....
Basically i have email via virginmedia.com, which i believe is all set up correctly with POP enabled etc and my phone/Tab 2 email client set up to never delete from server. Problem is the email comes to the devices fine and i can reply, send new email etc, but if i refresh the list to check for any new email, what was already in my inbox just disappears from my device, not into the bin, just gone for good!
I have Android 4.2.1 on the GNex ans 4.1 on the Tab 2. Remember this is the general email client and I am on Virgin Media, this is not the Gmail email app, I do not use that. would really like to be able to get my email on the move without knowing I will lose it all straight away!

After implementing some Android Apps, including several Map activities, I try to refresh the activity when the GPS listener's onLocationChanged() mehtod is called. I have no idea how to tell the map activity to refresh on its own and display the new coords. the coords to store will have to be in global values, so that the location listener will have access to it. In my sample GPS-class (see code below) I just changed the text of a text view....but how to do that in map view?

When I plug in the ADP1 and do the following: $ adb devices List of devices attached HT845GZ50887 device But, after connecting via the USB, my ADP1 device goes away after about a minute. I can also load an application from Eclipse to the ADP1 fine. But Eclipse lists in error in the Eclipse consolein about a min with: 2009-03-17 12:06:08 - DeviceMonitor]Connection Failure when starting to monitor device 'HT845GZ50887' : device (HT845GZ50887) request rejected: device not found If I then: $ adb devices List of devices attached Why would the device go away? USB debugging and Stay awake are both enabled. I've found that most of these types of problems are on Windows and have to do with the USB. I"m on Linux, though (gentoo).

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:

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.

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.
