gallery

问题 I'm working on android application that will have basic image gallery functionality included. I've managed to build activity that fetches list of photos from my application backend API and render them in android gridview within activity layout. This is how it looks like at the moment: However I'm having difficulties to build same gallery experience for user's device photos that were taken by camera and stored on device. Two solutions I considered were: Building my own image gallery. Starting

问题 how to make a gallery control to scroll one image at a time? Also what is a good way of making a continuous loop of those images? I tried overriding onFling, does not work at all. This moves image certain distance but does not really implement "true paging". @Override public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) { // return super.onFling(e1, e2, velocityX, velocityY); int kEvent; if(isScrollingLeft(e1, e2)){ //Check if scrolling left kEvent =

问题 I want to create a widget that behaves similar to the gallery widget but scrolls vertically instead of horizontally. That is images in gallery should be vertically placed on screen and can be scroll vertically.Does anybody help me please? 回答1: Assume that you want to have a single column of images and want to scroll vertically. Check the following example <GridView android:id="@+id/gridView1" android:layout_width="70dp" android:layout_height="fill_parent" android:verticalSpacing="2dp" android

问题 is there a way to get the DCIM path (it may be on sdcard or on device)on Api level 7? Environment.DIRECTORY_DCIM is available only from api level 8 回答1: I think the DCIM directory is never on the internal storage (My HTC Legend won't even take photo's without an sd-card present). The Environment.DIRECTORY_DCIM variable is just the String "DCIM" ref. The reason for storing images in /DCIM is compatibility with cardreaders (printers for example) who expect pictures to be available in /DCIM, so

问题 I want to retrieve only the name of the bucket (Albums). E.g. Camera, Download etc but not a list of Camera, Download etc from all the the photos so how do I retrieve one row each for each bucket name? What I mean like in Gallery Application, you have albums first e.g. Camera. When you clicked on it, it show all the photos of the camera. I can query the photos in a Camera Roll with the Where clause of the query. But what if I wanted only the name of each of the albums' name and not the photos

问题 I'm trying to take a photo using the android camera and telling it to save to the phone's gallery. I think i messed up on the path, but i can't seem to find my error. Could someone help me? I'm very novice at android. Code to call camera Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE); String uriToFileInExternalStorage = null; cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, uriToFileInExternalStorage); startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);

问题 my program is based on Google's Hello Gallery example: http://developer.android.com/guide/tutorials/views/hello-gallery.html Instead of using images, I create a bunch of EditText s in the constructor. My question is now: When I long click on an EditText, I want its Context Menu (with "select all", "copy" and so on) to be shown. I've tried setting an OnItemLongClickListener which calls the selected view via myGallery.getAdapter().getView(position, ...).showContextMenu() , but that runs into a

问题 I've been looking for a really easy/lightweight way to just be able to click thumbnails to switch the src of a larger image. This is what I've found: http://snipplr.com/view/8688/jquery-image-swap/ I haven't actually tried it out yet. Is this the best solution? The larger images to be swapped in will have the same width but a different height. Will this cause problems/is there something I need to add for this functionality? Would it be better to do a div with a background-image that swaps and

问题 I've seen some questions that address similar issues but none of the fixes seem to work for my situation. Basically I have multiple fancybox galleries on one page throughout the site, and when one clicks through one slideshow on the site, it continues from one gallery to the next. I want the galleries/fancybox instances to remain separate from one another. Basically I need the "rel" catagories to keep galleries separate and not bleed into one another.
