Android : Draw Over Thumbnail In Bottom Right Corner?
Sep 3, 2010
I have a video thumbnail and when you click on it, the video starts playing in the YouTube player. This works great, but It's not so clear that you have to click on the thumbnail to play, so I have a play button image that I want to draw over the thumbnail in the bottom right corner. How would I go about this? I currently have the thumbnail in a Drawable object and the play button in my drawable resource directory. I tried stuff with bitmaps and canvas but it's quite hard and I don't know if this is the way to go.

I am using relative layout to superimpose one smaller image on top of a larger one. I want the bottom-right corner of the smaller image to coincide with B-R corner of the larger image. Im using margin parameters in my layout xml (specifying measurement in dips) but this doesnt seem to work for all devices and resolutions - in some cases the small image is shifted by 4-5px from the border. Is it possible to specify the position of the smaller image without pixel values? Ie with gravity or something?

Purchased an inexpensive Android tablet (GDIPPO M7) recently. Worked pretty well, and am happy. Except today, when I turned it on and the word "DEMO" in bright red appeared in the corner. Have explored every conceivable setting to turn it off, and also did a factory reset, all to no avail.

On the bottom right corner of my eris on the back cover is loose. Loose enough to hear it and see it, whenever i hold it on that corner you can feel it is flimsy.Anyone think this is a good reason to return it, and get a replacement?

It was earlier this evening in fact. I went with my friends to check out the iphone 4 for the first time. So i decided to try and see the reception problem for myself. I took out my nexus one and did a side by side comparison. However to my surprise the iphone 4 was already at 2 bars the moment i picked it up, no idea why as my nexus one (Which was on the SAME carrier btw) had more bars on it at the same time. I carried on with the test anyway. You guys can guess the result.
The bars didn't drop completely as the coverage in Singapore is much better. But that doesn't mean it had better reception than my nexus one.
But the interesting thing was the lady beside me noticed us and asked "what are you trying to prove?". So while her daughter plays with the ipad, I kindly explained to her the whole issue with the iphone 4's revolutionary antenna having a ******ed flaw by which it loses signal when you cover the bottom left corner of the phone, unlike my phone which did not suffer as much as a drop. She then proceeded to saying "But they fixed the problem if you use the bumpers right?". Thats when i explained that you should not rely on a silly bumper case to improve reception when the actual problem lies with the antenna's design itself. But again she said "but the problem is fixed with the case right?". With one of the store sales person watching us the entire time, i still carried on and said "no it doesn't solve the problem, it only prevents it from happening". So we continued playing with the phone and she asked "you all are not fans of apple are you?". Trying not to be so direct, i just said "I actually used to have an iphone, but i didn't like it so i got this instead *shows nexus one*".
Ive never done this kind of thing before, so it was kinda thrilling. Especially when you know the staff is looking at you pseudo-promoting a rival phone. After looking at the iphone 4, i really think it does look beautiful, but it will still be crippled by the limitations of the OS regardless of how you jailbreak it. When i left the store i kinda hoped i shed some light into that lady's decision on whether or not to buy an iphone 4 or any other phone (Android or non-android).

I am creating a button programmatically. It is rounded and has a gradient background, and works fine and looks nice, but I couldn't do two things I wanted:
Set a 1 pixel stroke with a given color. I tried getPaint().setStroke(), but couldn't figure how to set the stroke color. How should I do it?
Align the gradient to the bottom of the button, no matter what height it has. Is this possible?
For reference, this is the code I'm using:

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...............

I have retrieved some cover art for an album (I have the id and a Bitmap) and now I want to set it into the MediaStore. I tried a bunch of stuff:
private static final Uri ARTWORK_URI = Uri.parse("content://media/external/audio/albumart");
public static void writeArtwork(Context context, Bitmap bmp, int albumId) {
ContentResolver res = context.getContentResolver();
Uri uri = ContentUris.withAppendedId(ARTWORK_URI, albumId);
LogUtil.i(TAG, "uri= " + uri);
if (uri != null) {
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.JPEG, 50, baos);.............

I am managing a bunch of PDF files in an android application maintaining a list of records in a SQLite database as well as storing the pdf files on the external storage. Now I would like to present a thumbnail of the first page of the pdf in my list view as part of each cell representing a pdf. I am aware of libraries like iText, fop.. on the JavaSE side that can render a PDF but I would rather not delve into embedding a large library like that. On a similar approach I would also rather not embed a native PDF viewer like droidreader, apv or vudroid.
Otherwise I could of course also get it rendered on a server via some webservice but that is a lot of headache as well. I am already using intents to get the pdf's displayed for the user so I was thinking it would be great if I could get a thumbnail via a intent call as a result somehow. However I found nothing on the web (e.g. on openintents) that indicates something like that exists. So I am a bit at a loss on what to do? What do you think is the best approach to get these thumbnails into my app? Are there any public intents available? Or did I just totally miss something and the SDK provides features for that already (it should imho but currently does not)?

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).

I know this has to be trivial but I just don't find the right resource, I guess.
So all I want to do is retrieving a thumbnail for a video. All I have is the absolute path to the file on the sdcard as a String. So please point me into the right direction.

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 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...

I have a specific drawable that I use as background in my app. It is not a solid color.
Now I want to add rounded corners to this drawable.
I only found the rounded corner available in a shape with a gradient or a solid color as a background but not another drawable.
Is there another easy way of adding rounded corners to a drawable?

Is there any way to select which picture will show as the photo album thumbnail? When I open the photo album the picture that shows as the thumbnail is hard to see and I would like to have another pic as the album thumbnail/icon.I have tried erasing all of the photos, clearing the cache and reloading the photos in various orders but no matter what I try the same photo shows as the thumbnail. Is there any way to change it?

For a while now the thumbnail gallery has sometimes merged pictures - so on the thumbnail it's actually a combination of more than 1 picture. This hasn't really bothered me until recently because the more pictures I take the worse it's getting, so much so that I can't always tell which picture I'm going to be looking at until I actually select it. In every case the picture views correctly on the screen when I view them one at a time, it's just a problem with the thumbnails. I've attempted to clear the gallery cache which made it appear slightly better but not by much. I've checked the DCIM / .thumbnails folder but there's just loads of files in there saying file and RAW file and to be honest I don't know what it's all about. I've trawled the net and checked the forums but cannot seem to see a solution - does anyone know what I can do in order to solve this?

I have an HTC one s, had it for a few months and just today it started to eat up all the memory on the "external card".
It is located in DCIM .thumbnails.
I know there is a fix of changing the folder to read only and sorts.(changing the file to read only works for a few moments then a new file generates with a new number.
But I do not just want to do a fix, I would like to know how I can trace what is causing it and fix it. The thumbnail file keeps increasing in size when I erase more files, right now it is at 1.2gb.
So my question, What is causing the thumbnail to be getting to 1.2gb, a larger size then my photos stored.
