please check image hereI need to set last taken image form gallery in image view or on Image button automatically just like used in default camera ,some body help me to sort out this problem
We can get the last taken image from MediaStore,
String[] proj = new String[]{
MediaStore.Images.ImageColumns.DATA,
};
final Cursor cursor = getContentResolver()
.query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, proj, null,
null, MediaStore.Images.ImageColumns.DATE_TAKEN + " DESC");
if (cursor.moveToFirst()) {
String lastImageLocation = cursor.getString(0);
}

in my app I use SqLite Database "Templates", where I have table "favourites", constains of four columns "id", "description", "imagePath", "category". I would like user to be able use their own images in my app, like this:
When user click button, he choose image from gallery, write description and choose category of image. I know I need use Content Values to do this. But how can I do my table has imagePathes, i.e how can I show them later using RecyclerView and Picasso?
You can load image from device memory:
Picasso.get().load(new File("path-to-you-image/image.png")).into(imageView);
If you are asking "how to get image path" - you can get it in the onActivityResult method:
Uri selectedImage = data.getData();
String[] filePathColumn = { MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(selectedImage,
filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();
I want to build a image slider that can shift images automatically with looping all images from phone's gallery. My android device is android 4.0.4. Can anyone help me out?
I have successfully built a image slider that can shift images automatically, but all the images are from the drawable resource that I created using Android Studio. I want the images come from gallery for better user interface.
My code is like this:
int images[] = {R.drawable.slide1, R.drawable.slide7, R.drawable.slide10};
It requires looping with array to do this, but I am a beginner of java.
1) content provider may help. like
private ArrayList<String> getImages(Context context) {
Uri uri;
Cursor cursor;
int column_index_data, column_index_folder_name;
ArrayList<String> listOfAllImages = new ArrayList<String>();
String absolutePathOfImage = null;
uri = android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI;
String[] projection = { MediaColumns.DATA,
MediaStore.Images.Media.BUCKET_DISPLAY_NAME };
cursor = context.getContentResolver().query(uri, projection, null,
null, null);
column_index_data = cursor.getColumnIndexOrThrow(MediaColumns.DATA);
column_index_folder_name = cursor
.getColumnIndexOrThrow(MediaStore.Images.Media.BUCKET_DISPLAY_NAME);
while (cursor.moveToNext()) {
absolutePathOfImage = cursor.getString(column_index_data);
listOfAllImages.add(absolutePathOfImage);
}
return listOfAllImages;
}
loading images from gallery with content provider
also look to the file ways as those are also useful.
listing files
loading images from file path
I am developing an android applicaiton. This application get all thumbnail images from gallery. I want to sort these thumbnails by date, but I can't do it.
Please help me.
Get all images
// Set up an array of the Thumbnail Image ID column we want
String[] columns = {MediaStore.Images.Media._ID};
String orderBy = MediaStore.Images.Thumbnails._ID + " DESC LIMIT 10";
// Create the cursor pointing to the SDCard
cursor = getActivity().managedQuery(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI,
columns, // Which columns to return
null, // Return all rows
null,
orderBy);
// Get the column index of the Thumbnails Image ID
columnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Thumbnails._ID);
myGalleryImages = (GridView) view.findViewById(R.id.my_gallery);
myGalleryImages.setAdapter(new ImageAdapter(getActivity()));
set images
// Move cursor to current position
cursor.moveToPosition(position);
// Get the current value for the requested column
int imageID = cursor.getInt(columnIndex);
// Set the content of the image based on the provided URI
holder.image.setImageURI(Uri.withAppendedPath(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, "" + imageID));
Update columns and orderBy like this:
String[] columns = {MediaStore.Images.Media._ID, MediaStore.Images.ImageColumns.DATE_TAKEN};
String orderBy = MediaStore.Images.ImageColumns.DATE_TAKEN + " DESC";
and see if that helps.
You could also fetch real images instead of thumbnails and use image loading library that will take care of proper re-sizing. In this case replace your Thumbnails references with ImageColumns
this code will save the first 100 thumbs (SORTED by date)
Cursor cursor = this.getContentResolver().query( MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI,
projection, // Which columns to return
null, // Return all rows
null,
"image_id DESC");
// Get the column index of the Thumbnails Image ID
int columnIndex = cursor.getColumnIndex(MediaStore.Images.Thumbnails.DATA);
for(int i =0;i<cursor.getCount();i++){
if (i==100) break;
cursor.moveToPosition(i);
mImagesFromGallery[i] = cursor.getString(columnIndex);
}
cursor.close();
My app will display the complete list of images in my custom gallery .For this, I'm using ContentProvider of Image Thumbnails. Upon selecting the thumbnail's I need to display the actual image.According to my understanding Gallery's image do have same unique ID in Thumb and Media Table.
Here is the code. Firstly I queried Thumbnail's ContentProvider and saved URL and ID.
String pictureThumbTemp[] = { MediaStore.Images.Thumbnails._ID, MediaStore.Images.Thumbnails.DATA };
Cursor imagecursor = context.getContentResolver().query (MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI,
pictureThumbTemp,null, null, null);
Later I am displaying thumbs in Grid.
Upon selection of thumbnail, I have to display original image. I'm trying to retrieve the original image like
String pictureImageTemp[] = { MediaStore.Images.Media._ID, MediaStore.Images.Media.DATA };
Cursor imagecursor = context.getContentResolver().query( MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
pictureImageTemp, MediaStore.Images.Media._ID + " = " + mediaID + "", null,
MediaStore.Images.Media._ID);
Overall, I'm showing thumbnail through it's url and upon click I'm querying the thumbnail's media ID in Original image table.
But it is returning a cursor with 0 results.
Please help me out.
Thanks,
sha.
I cracked out a way which worked out.
Retrieved the cursor for Original Images.
From that I pulled the ID for every image and Queried the Thumbnails for the ID which returns a cursor containing paths.
Find the code snippet below.
String pictureCols[] = { MediaStore.Images.Media._ID, MediaStore.Images.Media.DATA };
Cursor imagecursor = mContext.getContentResolver().query(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, pictureCols,
null, null, null);
imagecursor.moveToFirst();
mImageUrls = new ArrayList<String>();
try {
// Iterate the cursor for Image urls
for (int index = 0; index < imagecursor.getCount(); index++) {
imagecursor.moveToPosition(index);
preparePicture(imagecursor);
}
} catch (Exception e) {
e.printStackTrace();
} finally {
imagecursor.close();
}
}
Here is the code for preparePicture method
private void preparePicture(Cursor imageCursor) {
// get the ID for the original image
int idColumnIndex = imageCursor.getColumnIndex(mSelectedImage.mediaID);
Long id = imageCursor.getLong(idColumnIndex);
// Thumbnail image Cursor for this specific image.
String thumbCols[] = { MediaStore.Images.Thumbnails._ID, MediaStore.Images.Thumbnails.DATA };
Cursor thumbCursor = MediaStore.Images.Thumbnails.queryMiniThumbnail(mContext.getContentResolver(), id,
Thumbnails.MINI_KIND, thumbCols);
thumbCursor.moveToFirst();
// Save thumbnail URL in MediaInfo
dataColumnIndex = thumbCursor.getColumnIndex(mSelectedThumb.data);
String thumbURL = thumbCursor.getString(dataColumnIndex);
thumbCursor.close();
mImageUrls.add(url);
}
Finally, I will have all my Thumbnail urls in the ArrayList.
The same logic is not working for video thumbnails. Of course that is a different question :)

Sha.
try this one
final String[] pictureImageTemp= { MediaStore.Images.Media.DATA, MediaStore.Images.Media._ID };
Cursor imagecursor = managedQuery(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, pictureImageTemp, null,
null, MediaStore.Images.Media._ID);
I am trying to rename an image in Gallery taken from Camera to give a new name. When I renamed the file the original image disappears showing 2 black squares . Can any one help me in sorting this issue by telling me procedure to rename Gallery Image.
Path is as follows : /mnt/sdcard/DCIM/Camera
I tried to update the Image title through content provider as below:
ContentValues val = new ContentValues();
val.put(Images.Media.TITLE, "ImageTitle23");
getContentResolver().update(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, val, null, null);
The image title is changed in Gallery.
But when I try to query the updated image as below I am getting the name same as previous one :
final String[] imageColumns = { MediaStore.Images.Media._ID, MediaStore.Images.Media.DATA };
final String imageOrderBy = MediaStore.Images.Media._ID+" DESC";
Cursor imageCursor = managedQuery(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, imageColumns, MediaStore.Images.Media._ID+"="+id, null, imageOrderBy);
if(imageCursor.moveToFirst()){
int idd = imageCursor.getInt(imageCursor.getColumnIndex(MediaStore.Images.Media._ID));
String fullPath = imageCursor.getString(imageCursor.getColumnIndex(MediaStore.Images.Media.DATA));
Can anyone help me in sorting out this issue?
The MediaStore looks for changes in your pictures BUT it will not react to all changes in real time. Each time you do such a modification, you should ask the MediaScanner to scan this file:
MediaScannerConnection.scanFile(
getApplicationContext(),
new String[]{file.getAbsolutePath()},
null,
new OnScanCompletedListener() {
#Override
public void onScanCompleted(String path, Uri uri) {
Log.v("grokkingandroid",
"file " + path + " was scanned seccessfully: " + uri);
}
});
Also, you should check this blog post that gives a lot of useful informations on this usecase.
The Gallery is interacting with the MediaStore content provider. If you change the name of the image file you probably need to update the field in the content provider.
You can read up on it in the MediaStore reference : http://developer.android.com/reference/android/provider/MediaStore.Images.Media.html
Potentially you can just trigger a refresh of the MediaStore. Look at this thread : How can I refresh MediaStore on Android?
