Android Display Images From Specific Folder in Gallery View

android, directory, gallery

Solution

Figured it out! Below is the pasted code for anyone who wants to do something similar.

Cursor imagecursor = getContentResolver().query( MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
                        columns, 
                        MediaStore.Images.Media.DATA + " like ? ",
                        new String[] {"%/yourfoldername/%"},  
                        null);

Problem

I'm trying to make a little app that displays only images from a specific folder in a gallery view. I have found a few examples, but every single one just ends up displaying only 1 image. This example I will post below was a WONDERFUL help, it does almost exactly what I want it to do, I just need to change it to display images from the specific folder, and not all folders. I've given this a few days worth of attempts, but I just don't seem to be adding in the right code. I feel like its a very simple thing that I am missing too. Any help would be greatly appreciated! ``` public class AndroidCustomGallery extends Activity { private int count; private Bitmap[] thumbnails; private boolean[] thumbnailsselection; private String[] arrPath; private ImageAdapter imageAdapter; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); final String[] columns = { MediaStore.Images.Media.DATA, MediaStore.Images.Media._ID }; final String orderBy = MediaStore.Images.Media._ID; Cursor imagecursor = getContentResolver().query( MediaStore.Images.Media.EXTERNAL_CONTENT_URI, columns, null, null, orderBy); int image_column_index = imagecursor.getColumnIndex(MediaStore.Images.Media._ID); this.count = imagecursor.getCount(); this.thumbnails = new Bitmap[this.count]; this.arrPath = new String[this.count]; this.thumbnailsselection = new boolean[this.count]; for (int i = 0; i < this.count; i++) { imagecursor.moveToPosition(i); int id = imagecursor.getInt(image_column_index); int dataColumnIndex = imagecursor.getColumnIndex(MediaStore.Images.Media.DATA); thumbnails[i] = MediaStore.Images.Thumbnails.getThumbnail( getApplicationContext().getContentResolver(), id, MediaStore.Images.Thumbnails.MICRO_KIND, null); arrPath[i]= imagecursor.getString(dataColumnIndex); } GridView imagegrid = (GridView) findViewById(R.id.PhoneImageGrid); imageAdapter = new ImageAdapter(); imagegrid.setAdapter(imageAdapter); imagecursor.close(); ```
