Android :: Create Gray Box 70x70px And Put Thumbnail In It To Align Image With Box
Jan 12, 2010
I've got thumbnails which larger side is 70px (e.g 70x40 or 52x70).
I need to create a gray box 70x70px and put the thumbnail in it, so that image is aligned with the box at top vertically and center horizontally.
How to do that?
I've tried with an ImageView 70x70px, gray background, but image is not positioned as it should (it's in vertical and horizontal center, instead of vertical top and horizontal center).
I've also tried wrapping it with LinearLayout 70x70px, gray background and then positioning it, but then i get 1 or 2px line between LinearLayout and ImageView. I tried to set padding and margins to 0, but the gray line stays on...

how will you know that this thumbnail points to which actual image in the SD card. I have a problem with MediaStore.Images.Thumbnails displaying blank previews. Though I followed mihai fonoage part 2 on how to load it properly by using scaling. Still, I got duplicate images. So instead of using MediaStore.Images.Thumbnails I used MediaStore.Images.Media instead but it loads the actual image but oading is too slow even if bitmap is scaled. That's why I was wondering if there's a way to know which actual image is the thumbnail pointing or is there a way to know the exact location of the thumbnail for this actual image (The other way around).

How to obtain ID of an image by the ID of the thumbnail?
And what about going from original image to thumbnail ID? Is that possible? I saw MINI_THUMB_MAGIC but it seems there is an issue with it.

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've tried all scaletypes, but all of them result in the image to be at the left corner of the imageview.

I have a series of buttons on a main menu. Instead of the standard side by side, or one on top of the other, I'd like them to be aligned around a semi-circle. Since I can't drag and drop the buttons to the place I'd like to in the designer, I was wondering the best way to do this? Can I do it in the XML, or would it be best to do it programatically?

I have been trying to create a ListView Activity with an ImageView in every row. I've used this tutorial: http://developer.android.com/resources/samples/ApiDemos/src/com/examp... The issue is that there are always some dividers missing whenever I run the example. The dividers are disappearing/appearing and flickering as i scroll the list (tested in emulator and HTC Tattoo). Strange is that the same example downloaded from the market (API Demos app) behaves correctly. Here is a screenshot of how it looks: http://yfrog.com/4cnokp.

I have 10" MID tablets and I was messing around with the root files on 1 of them to try and get the 2nd camera to work but I messed it up and now I need to re install the operating system.
How can I create an exact image of the 2nd tablets installation so I can just boot from the image file on the broken tablet?I have searched all over and can't seem to find out how to do this. I have not even been able to see the hidden files on my PC. I tried android commander and similar programs but none of them recognized my device.

I have a screen where I need to put a background image. I need to display only a part of the background image in each screen . Now when the user swipes towards left , the next screen will be displayed taking another portion of the background image. This transition from the first to second screen should give a 3 Dimension effect of moving the screen. I am unable to get any help form Android forums.

i'm trying to fetch a thumbnail with picture URI using these code below:
long id = ContentUris.parseId(selectedImageURI); String[] projection = { MediaStore.Images.Thumbnails.DATA }; Cursor c = Images.Thumbnails.queryMiniThumbnail(getContentResolver(), id, Images.Thumbnails.MINI_KIND, projection);
unfortunately, it's always return me the null cursor. finally, i found HTC hero never generate picture thumbnail under "sdcardDCIM.thumbnails", but only create a picture under this folder: "sdcardDCIM100MEDIA", which means i can only get the full size picture. What's am i supposed to do? create a thumbnail by myself?

I tried to create a video thumbnail as described here. I also read the reference here. In my app I first let the user choose a video with: startActivityForResult(new Intent(Intent.ACTION_GET_CONTENT).setType("video/*"), ACTIVITY_PICKVIDEO);
Then I determine the video ID with: fileID = Integer.parseInt(contentUri.getLastPathSegment());
So, the video content://media/external/video/media/5 would have the ID 5...............
