I want to start in built gallery activity for multiple selection.

I have tried this, but it selects only one image.

Thanks in advance..!

You have to create your own list of images having checkboxes to select multiple image files.

Use the below code to get the cursor for gallery and create a list adapter which will iterate over cursor and will give image. This image can be used to show in list view with checkboxes. 

String[] projection = { MediaStore.Images.Media.DATA };
Cursor cursor = managedQuery(uri, projection, null, null, null);

  • For this you need to get the images URI and then create an adapter for the cursor of that URI and create a list view of images. Please refere to this : http://coderzheaven.com/2011/03/select-an-image-from-gallery-in-android-and-show-it-in-an-imageview/ – Ravi Sharma Oct 21 '11 at 14:26
  • in that we are opening the gallery for selection, and only one at a time. – Noby Oct 21 '11 at 15:16
  • but i don't want to open gallery for single selection. is there any way with out starting activity, we should get all the images. – Noby Oct 21 '11 at 15:17
  • No man this is for a custom list of images from which you can select multiple images by using checkboxes. Just google around and you will find how to create a list of images. – Ravi Sharma Oct 22 '11 at 06:29

Download source code from here (Get all images from gallery in android programmatically)

public ArrayList<Model_images> fn_imagespath() {
        al_images.clear();

        int int_position = 0;
        Uri uri;
        Cursor cursor;
        int column_index_data, column_index_folder_name;

        String absolutePathOfImage = null;
        uri = MediaStore.Images.Media.EXTERNAL_CONTENT_URI;

        String[] projection = {MediaStore.MediaColumns.DATA, MediaStore.Images.Media.BUCKET_DISPLAY_NAME};

        final String orderBy = MediaStore.Images.Media.DATE_TAKEN;
        cursor = getApplicationContext().getContentResolver().query(uri, projection, null, null, orderBy + " DESC");

        column_index_data = cursor.getColumnIndexOrThrow(MediaStore.MediaColumns.DATA);
        column_index_folder_name = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.BUCKET_DISPLAY_NAME);
        while (cursor.moveToNext()) {
            absolutePathOfImage = cursor.getString(column_index_data);
            Log.e("Column", absolutePathOfImage);
            Log.e("Folder", cursor.getString(column_index_folder_name));

            for (int i = 0; i < al_images.size(); i++) {
                if (al_images.get(i).getStr_folder().equals(cursor.getString(column_index_folder_name))) {
                    boolean_folder = true;
                    int_position = i;
                    break;
                } else {
                    boolean_folder = false;
                }
            }


            if (boolean_folder) {

                ArrayList<String> al_path = new ArrayList<>();
                al_path.addAll(al_images.get(int_position).getAl_imagepath());
                al_path.add(absolutePathOfImage);
                al_images.get(int_position).setAl_imagepath(al_path);

            } else {
                ArrayList<String> al_path = new ArrayList<>();
                al_path.add(absolutePathOfImage);
                Model_images obj_model = new Model_images();
                obj_model.setStr_folder(cursor.getString(column_index_folder_name));
                obj_model.setAl_imagepath(al_path);

                al_images.add(obj_model);


            }


        }


        for (int i = 0; i < al_images.size(); i++) {
            Log.e("FOLDER", al_images.get(i).getStr_folder());
            for (int j = 0; j < al_images.get(i).getAl_imagepath().size(); j++) {
                Log.e("FILE", al_images.get(i).getAl_imagepath().get(j));
            }
        }
        obj_adapter = new Adapter_PhotosFolder(getApplicationContext(),al_images);
        gv_folder.setAdapter(obj_adapter);
        return al_images;
    }

Thanks!
