Jul 21, 2010

I use http://stackoverflow.com/questions/541966/android-how-do-i-do-a-lazy-load-of-images-in-listview/3068012#3068012 to load images in a ListView and a GridView. It works but the images are loaded form bpttom to top. How to fix that?

Bonus Question: Can I use a loading animation in a image view while the real image is loaded? Right now it's just a default image.

Android :: ImageView Clicked Change Image Source

Aug 16, 2010

I 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:

electronconfiguration.setOnClickListener(new View.OnClickListener() {
public void onClick(View drawable) { if (drawable.equals(R.drawable.element_el))
electronconfiguration.setImageDrawable(R.drawable.aluminum_el);
else if (drawable.equals(R.drawable.aluminum_el))
electronconfiguration.setImageDrawable(R.drawable.element_el);
} } );

Android :: Change Background Image Of Dialog Or View In Runtime?

Aug 9, 2010

I have a card game I created in android and it is possible to show the scores at any given time by clicking a menu option. I would like that scores dialog to show a different background image when it's loaded depending on factors like who's leading, etc. In my constructor, I have the following relevant code:

public ScoresDialog(Context context) {
super(context);

this.setTitle(R.string.scoresDialogHeading);
setContentView(R.layout.scores_view);
...
}

I have tried getting that view to change it in the showDialog method i wrote like so: findViewById(R.layout.scores_view).setBackgroundColor(Color.BLUE); However, I got a NPE... I tried moving this statement to the onStart method, thinking that the view is not yet initialized but got the same error... Any thoughts on what the right way to do something like that is?

Android :: Image View That Is Fixed Size Regardless Of Image Size

I have an ImageView which I want to always be the same size. If the image is smaller than the view, I'd like it to be centred in the view. If the Image is larger than the view then I'd like it scaled down - with aspect ratio preserved.I've had several attempts at this myself

Android :: View On Press Onpress - Change Background Color On Press - How Do Show That The View Is Being Pressed

Jan 5, 2010

I have, for the time being, a custom view with a 9-patch image as a border.

That custom view is placed three times in a LinearLayout, so it looks like this:

+------------------------+
| CustomView |
+------------------------+
| CustomView |
+------------------------+
| CustomView |
+------------------------+

I have attached a click event listener to the View, so it is clickable. But then I click it, I cant see that I am clicking it - there is no change in color.

So, Im thought that I'd attach a "onPress" listener, and then change the background of the view but I couldnt find such a listener.

So, the question is - how do I create the behaviour on the View so I can see that it is being pressed? this is normally done in Android with a green background to indicate that it is now being pressed.

Android :: Get Image Source From HTTPs URL?

Nov 11, 2010

I 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.

Android :: Set Image / Background Source Dynamically

Oct 11, 2010

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.

Android :: ImageView Scales Up Source Image

May 30, 2010

I 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?

Android :: Jigsaw Puzzle Constant Image Source

Jul 29, 2010

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.

However, the other fields are populated, but the image remains empty. Why?

Android :: Show Spinner Wheel Instead Of Image While Downloading Source

Oct 17, 2010

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.

Android :: View Image In Action View Intent?

Nov 16, 2009

I'd like to show a png or jpg I downloaded from the next in an image viewer intent, but can't get it to work.

Bitmap bmp = getImageBitmap(jpg);
String path = getFilesDir().getAbsolutePath() + "/test.png";
File file = new File(path);
FileOutputStream fos = new FileOutputStream(file);
bmp.compress( CompressFormat.PNG, 100, fos );
fos.close();
Intent intent = new Intent();
intent.setAction(android.content.Intent.ACTION_VIEW);
intent.setDataAndType(Uri.fromFile(new File(path)), "image/png");
startActivity(intent);

I know the bitmap is downloaded ok (use the same routine for supplying it my ImageView instances elsewhere in my app) - I think it wrote to file ok, I can see it on disk and the file size is correct. The intent is launched but an exception is thrown: then the new activity just sits there, blank. How does this work?

General :: Light Painting Software That Uses Image As Source (not Just Text)

Aug 13, 2012

I 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 can just imagine some trippy picture I could make with this

Android :: Click On Image / Pass Image To Another Activity / Page

Oct 12, 2010

I am very new to Android (and Java) originally a C# developer.. and am struggling with the concepts and terminology.
I have been through almost all the tutorials and have decided to start on my first test app.The first part of my app is going to involve using the gallery widget (based on the hello gallery tutorial) to display a load of images. (these images will eventually come from the phones camera, but I will cross that bridge later!) My images are currently stored in the drawable folder in my project.As a first step I want to just have the user click on an image and it pops up full screen, just so I know how to get reference to it, but I am struggling. Evetually I want the user to click an image, then a window/activity(?) will open asking them for a bit of text. This will then be store in sqllite against the image. Code...
