Android :: Show Single Image With Zooming / Panning
Feb 26, 2010
I have a png and a jpg image on disk. I'd like to use any built-in intent (if any are available) to view the image (just a single one at a time). Something like this:
Intent intent = new Intent();
intent.setImagePath("/blah/myimage.jpg");
startActivity(intent);
is there a built-in intent in android to do this, or do I have to write my own image viewing-activity? It would be cool if there was one that had panning/zooming as found in WebView.

How do you do you fetch a single RSS feed and show it in an ListView?
I realize there's hundreds of ways, but a clean and simple example would be appreciated.

I want to create a scrollable map and trigger different actions when the user touches a different areas. With iPhone, it was easy by putting buttons on top of the image. How do I do it in Android? I used a custom view to enable scrolling in both directions. Now how do I make different parts of the image trigger different events on click?

I have compiled Android source code already (which I downloaded using GIT), and I am being editing the source code of an Application for testing on Emulator, each time I wanna see results I have to re-Compile the source code again using 'make' I am pretty sure that there is a way to partly-compile the image.

I'm developing an app for Android 2.1 upwards. I want to enable my users to select a profile picture within my app (I'm not using the contacts framework). The ideal solution would be to fire an intent that enables the user to select an image from the gallery, but if an appropriate image is not available then use the camera to take a picture (or vice-versa i.e. allow user to take picture but if they know they already have a suitable image already, let them drop into the gallery and pick said image). Currently I can do one or the other but not both.
If I go directly into camera mode using MediaStore.ACTION_IMAGE_CAPTURE then there is no option to drop into the gallery. If I go directly to the gallery using Intent.ACTION_PICK then I can pick an image but if I click the camera button (in top right hand corner of gallery) then a new camera intent is fired. So, any picture that is taken is not returned directly to my application. (Sure you can press the back button to drop back into the gallery and select image from there but this is an extra unnecessary step and is not at all intuitive). So is there a way to combine both or am I going to have to offer a menu to do one or the other from within my application? Seems like it would be a common use case, surely I'm missing something?

As we know android comes with 3 or 5 or 7 home screens. I want to set wallpaper image on a single home screen programetically and fix it for all other home screens.
I used following code :
Display display =((WindowManager) getSystemService(Context.WINDOW_SERVICE)).getDefau ltDisplay();
Bitmap bmp = Bitmap.createScaledBitmap(wallpaperImage,display.g etWidth(),display.getHeight(), true);
setWallpaper(bmp);
and wallpaper image is set but it spans across all 3 home screen. How can i fix it to one screen so that if user swaps home screen a single image will display.

I am trying to write an app which has an ImageView and the app allows to perform panning on the image. I also want to register context menu with this ImageView so that on long press Context menu comes up. I tried playing around with the onTouch method, but could not get it working.
On long press, i do see context menu. But, while panning also the context menu comes up. I want that context menu is displayed only when long press is performed and not while panning. If I return true from the down event, the context menu fails to come up.
Please find the snippet of the code below for the reference. Code...

I need to know when the user is panning the map so I can check if they've panned outside of the initial radius that I fetch data from the API with when the app launches. If the user pans outside this radius, when they stop panning I will get the new center point of the map and fetch new data with that geo-point. So far I can't find anything in the Google Maps API docs [and I've inspected the entire class tree] that notifies developers when any animation actions are occurring or completed.. It seems weird that Google wouldn't give us some sort of event listener or protected method to override on the MapView or something to do this.
I looked into what methods were available to override on the View class and it does have onAnimationEnd() but I guess panning or zooming the map doesn't count as an animation or is never passed up from the MapView or something... I tried running a simple log in onAnimationEnd() and it is never being called. Searching the interwebs gave me nothing but some never-successfully-answered posts.

The Maps API always had its issues... since updating my Nexus One to 2.2.1 FRG83D earlier today, I see a problem more serious than anything prior. This applies to both Google Maps and (any) app that uses the Maps API (that I have tested). It's pretty obvious and simple, and cannot be remedied by rebooting the device: When panning the map view (no zooming that would trigger a complete re-load), map tiles that were already loaded, are cleared and reloaded. This can occur multiple times until the map view settles down. Looks pretty wild.

Had no problem getting my phone to play nice with our exchange server at work and emails are coming/going fine.
However, there are some configuration items I have a big issue with as it relates to the 'look' of the email (coming from a BlackBerry).
1. Is there any way to have a single folder show my received items and sent items combined? My BB had this and it was very useful.
2. How can I edit the way my folders are displayed at the top horizontal bar? The sidescrolling folder display is awkward, it puts my inbox first (good) but then all subsequent folders are listed alphabetically; it pays no attention to their order on my desktop and also shows sub-folders of other files. Any way to change this?
3. Is there a way to change the way emails show as unread? The difference b/n read and unread is only a shade of grey, and difficult to see outside.

I am attempting to create a very graphically intensive android application. Almost all of the UI is based on bitmaps and I would like to support as many different devices as possible and to have the app look great in all of them.Is it possible to embed different resolutions for each image and have a different image displayed on each device. I am aware of stuff like hdpi folders etc. as well has units like dip etc., but that still leaves too many variables as to how the image is displayed. I would like to not have the images scaled at all to avoid losing image quality.For instance on my high resolution device I would like an image to be exactly 100px and then on a medium resolution device I would like a lower resolution image to display and be exactly 80px. If I use display independent units, I cannot ensure that the images will be of a particular size.

I've had my Incredible for a couple months, and this just started happening a couple days ago. First, my home screens shifted to the left (as if I was doing it with my finger). I would leave the screen on, lay it down on a table top, a few seconds later, shifted to the far left again. I pulled up some things with text input boxes, and again it kept trying to shift the cursor to the left.
I checked and since it's still under warranty Verizon will swap it out. It only happened for a couple days, and has quit since (happened a few days ago). Any ideas what may have caused it? Think it's worth going ahead and swapping it while it's still under warranty? Hate to run the risk of it doing it again later, of course knowing my luck I'll get a screwed up one when I swap it out!

I use this code in my getView:
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View v = convertView;
if (v == null) {
LayoutInflater vi = (LayoutInflater)getSystemService
(Context.LAYOUT_INFLATER_SERVICE);
v = vi.inflate(R.layout.listrow, null);
}
Order o = items.get(position);
if (o != null) {
TextView tt = (TextView) v.findViewById(R.id.toptext);
ImageView thumb = (ImageView) v.findViewById(R.id.icon);
if(o.getOrderDrawable()!=null){
thumb.setImageDrawable(o.getOrderDrawable());
}
else{
tt.setText(o.getOrderTitle());
}
}
return v;}
The problem is when scrolling; sometimes the correct image shows, but sometimes when scrolling back/forward, the images shows randomly and that is not associated with the row. The images are downloaded from the web.

I am developing an app in android, which basically visits a given url and downloads an image. Now i want to populate this downloaded image and show it in thumbnail view. I have tried out displaying the same from SD Card, but when i am doing the same for downloaded files, it doesn't seems to work.
public View getView(int position,View convertView,ViewGroup parent)
{
System.gc();
ImageView i = new ImageView(mContext.getApplicationContext());
if (convertView == null)
{
//imagecursor.moveToPosition(position);
//int id = imagecursor.getInt(image_column_index);
//i.setImageURI(Uri.withAppendedPath(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, ""+ id));
i.setImageBitmap(bitmap);
i.setScaleType(ImageView.ScaleType.FIT_CENTER);
i.setLayoutParams(new GridView.LayoutParams(100, 100));
}
else
{
i = (ImageView) convertView;
}
return i;
}

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.

I want to scale and display images which are dynamically loaded to a certain maximum size. The way I'm doing this is to set the layout_width and layout_height of my ImageView to the maximum dimensions and setting the scaleType to "fitCenter".
But here's the problem. This is inside a RelativeLayout and I want to show text directly under the image. In portrait mode, the text is way at the bottom (because of the height I have set). So I want the ImageView to scale down to the actual visible image size which is what it would seem like adjustViewBounds="true" should do.
Am I wrong in this assumption? Or is there a better way to do what I'm trying to do? Because I've been unsuccessful to this point!
