I'm populating a list from the DB and I have a image field in the DB which contains a URL to a image file.
ListAdapter adapter=new SimpleCursorAdapter(this, R.layout.row, constantsCursor,
new String[] {"title", "subtitle", "image"}, new int[] {R.id.value, R.id.title, R.id.icon});
However, the other fields are populated, but the image remains empty. Why?

I've built an application that loads XML from a server, then creates a list of items and with that I create and adapter that I set with setListAdapter(my adapter);
The problem I'm having now is that creating the list and adapter takes time, so I was thinking on creating just like 20 entries and populate the list, then create the rest on runs background or maybe when the person gets to the bottom (like gmail application).
I want to look at the source code for the ListAdapter class without downloading the entire Android source code tree. Is there a way to do that?
View 4 Replies View RelatedI have a scroll view with lots of image buttons. I want to change the image for an image button when it's pressed. The thing is that I want the image to remain until another image button is pressed. That's why I couldn't use a selector. What is the best practice to achieve his?
View 3 Replies View RelatedI am trying to get an image from a https url but it doesn't seem to display and get the image correctly but works fine on my computer browser. I have tested out a http url pointing to a different image and it works fine. My code is below:
public Bitmap getContactPhoto(String url) {
Bitmap pic = null; try { pic = BitmapFactory
.decodeStream((InputStream) new URL(
"https://mail.google.com/mail/photos/static/AD34hIjbK2m-Lj333E4nBcCkBC3MYl2tTs0xizuSqUOP3-Jd6DOrpFg1M5HG8jXh0MuPbeFepInZZDu92Dx8ST4b59EbOKmfYTortuuO3P1_Ohyu7b7a3gc")
.getContent()); } catch (MalformedURLException e) {
// TODO Auto-generated catch block e.printStackTrace(); } catch (IOException e) {
// TODO Auto-generated catch block e.printStackTrace(); } return pic; }
Here is the code from the activity class that calls the method above:
private ImageView mContactPhoto; private ContactDetailsViewHelper mViewHelper;
mContactPhoto = (ImageView) findViewById(R.id.contact_photo);
mViewHelper = new ContactDetailsViewHelper(mContext);
mContactPhoto.setImageBitmap(mViewHelper.getContactPhoto(mDetail.getImageRef()));
ignore the mDetail.getImageRef, that passes the real url value but for this case I tried hard coding the url as you can see from the getContactPhoto method.
I'm trying to display an image using a URL. When I run the code I get an error telling me the application has stopped unexpectedly. Can anyone see what's wrong in my code.
Bitmap bmImg; URL myFileUrl =null; try {
myFileUrl= new URL("http://www.starling-fitness.com/wp-content/ 240384vBdA_w.jpg");
} catch (MalformedURLException e) { // TODO Auto-generated catch block e.printStackTrace();
} try { URLConnection conn= (URLConnection)myFileUrl.openConnection();
conn.setDoInput(true); conn.connect(); int length = conn.getContentLength();
int[] bitmapData = new int[length]; byte[] bitmapData2 = new byte[length];
InputStream is = conn.getInputStream(); bmImg = BitmapFactory.decodeStream(is);
/*timetableImage.setImageBitmap(bmImg);*/ setContentView(R.layout.timetable);
ImageView iv = (ImageView)findViewById(R.id.timetableImage); iv.setImageBitmap(bmImg);
} catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace();
}
Is there any possibility to set background image dynamically? I try to explain what I mean.
String picVariable = getPictureFromServer();
ImageView image = (ImageView)v.findViewById(R.id.dynamic_image);
// I know, that doesn't work, but that's the way I looking for
image.setBackgroundResource(picVariable);
I also read this article. It would suggested in one answer, to use java reflection to get a field of the R class by name. But I've never used reflextion before.

View 4 Replies View RelatedI can't seem to get my ImageView to display its source image in its original size. The ImageView looks like this:
<ImageView android:id="@+id/Logo"
android:src="@drawable/logo" android:layout_width="wrap_content"
android:layout_height="wrap_content" > </ImageView>
The source image is 140 pixels wide, yet on the Nexus One's screen, which is 480 pixels wide it uses up half of the width. Using absolute values in px or dp for the width and height changes nothing. The image also looks very antialiased from the upscaling. Why is this happening and how can I prevent it?
I am creating a basic jigsaw puzzle for android. The code is almost ready but I am facing problem in finding images for the puzzle. The User should be able to get new image every time they click "Next". Upon selecting an image, the application will create puzzle for the selected image. For this requirement, I need a constant source of public images. My app will be free, so I think it can be considered as Non-Comercial usage of images.
View 4 Replies View RelatedI am working on changing the image being shown when I have my ImageView Clicked. I am trying to use a similar code that I used for accomplishing this with a TextView but I can't seem to find the right terms to get it to work. Here is my current code:

public void onClick(View drawable) { if (drawable.equals(R.drawable.element_el))
electronconfiguration.setImageDrawable(R.drawable.aluminum_el);

I am going to create a gallery view where the user shall switch between different pictures of products. On some of them is going to be a label like "sale" and a short discription. On startup I want to display a loading animation at that place until the product photo is downloaded.
Use layer list or state list for one product photo?
Could you please show me, how to set that up?
How to make that spinner spin?
How to turn it on or off (how to access the layer list through code)?
By the way, is "spinner" the best word for this? It seems to stand for several things. Feel free to edit this question, if I didn't hit the right words.

View 1 Replies View RelatedI recently started playing with what people call "light painting" using my cell phone and tablet, and it can be fun... but, what I think would really be awesome is if I could pre-load an image, and have it 'paint' it as I move the device around. This is basically identical to the other light-painting apps, but none of them seem to offer this functionality.

I was playing with contacts just now, and I saw the upside down icon again. Then I was curious, went to see other contacts, and I noticed the Android icon facing right, then facing left in other instances. There is no rhyme or reason as to when the Android icon will change positions, but it is there.

View 4 Replies View RelatedI have been dealing with android layout and my first app was based on wifi location, and the icon was used to indicate the current location. What I found was that it was really difficult to programmly add an imageview on top of a Scrollview at certain position. Only succeed by using the deprecated AbsoluteLayout with new AbsoluteLayout.LayoutParams(width, height, x, y). But there should be other ways to deal with it, like Google map, after zooming or scrolling the location indicator is still pointed right.
View 1 Replies View RelatedI'm using the android SDK in Eclipse on Linux. I've used the code at itp.nyu.edu/~sve204/mobilemedia_spring10/androidCamera101.pdf to write an app to store an image captured through the camera onto SD card (there are various examples of this around). It works ok except that the image returned by the camera is not what's on the preview surface. Instead of getting the checkerboard image I expect, I get different versions of the android icon depending on which version of target I choose. If I render the image to an ImageView this is confirmed as it's the same as on the SD card.
View 1 Replies View RelatedI just got my droid 2. All set up and rolling. However, I am adding shortcuts to my contacts on my desktop (ala the d1) by pressing and holding the screen, then Shortcuts > Contact. I scroll to the contact and select it. and it adds them to the home screen. Unfortunately, it adds them with the WRONG icon. It IS an existing icon for a user just not the user I am selecting. Also: It is only when I add it to the home screen as a shortcut when it gets jacked. Anyone else seeing this or have a solution? Also, I use google to sync all my contacts. I use Gmail to set the icons. There is only a certain size which can be used. but on the D2, the same contact icons/images seem to be blown out. Like I COULD use a bigger size image, bug I dont think that Google allows it? Anyone know what size contact image the 2 can handle and a way to use that image through Gmail? So far, moving from a D1 to a D2Im not completely impressed. but it is faster and works well. except for this issue. And the moto blur crap. Also to note... when using the (HORRIBLE) motorola contact widget the icon/image IS correct. but cmon, is this widget even useful? How many people have only one number? And I need a 4x4 widget for one contact... mobile, home, text, email, etc.. BS. Really the function on the D1 of adding a shortcut to a contact is much better. add em, click the icon, then it asks you what you want to do (text, call, email, talk, etc)... the D2 still does this but you have to go into Contacts and click on the person first before getting the options.

I'm on a Galaxy S4. I'm running Nova Launcher as well. I've noticed since I got this phone a few weeks ago that I can set icon images from icon packs, but if the icon pack is downloaded as image files I can't.
long press app I want to change icon for > click edit > click the icon image > select Gallery (or Astro file mgr) > select the image I want > takes me to an edit screen where I can crop etc, I click 'okay' > it says 'preparing image' and goes away, leaving me back at the edit icon screen where the icon image is still the same as before.
Could it be because my icon images are stored on the SD card? If so, where do you guys normally store icon packs that are download as regular images?
So I extract any APK, and then go into "Res" folder, but all I see is the icon for the apk.
Where are the rest of images?

Each drop down selection has it's own hidden value that is pulled. I need this value to be hidden for me to allow me to know which ID they choose.
