How to get the id from the data base basd on the listview items

This is one of the class in my app. In this class list of recipes are displaying which were are also stored into the sqlite database. In my db I stored the each recipe name, quantity, image and price. Now i would like to set the edit text value in this class where the edit text value is the quantity value in db. but i don't know how to retreive the quantity value of a particular list items in the db and setting that value in edit text. I am getting all the db count values and stores in arraylist but how to get the particular recipe quantity?

Android multiple contacts from groups and images

I want to do the following.
Pick up three to five contacts out of a special group of contacts or all contacts.
In the list it would be nice to show the contact image.
The selected contacts should have the following information (contact-id, first name, the small version of the contact image to save it as a blob in the database)
I found solutions for the different aspects.
-select multiple contacts:
How to obtain the checked rows in a custom view list
-show contacts from one group
getting contacts from a specified group in android
- photo problem
Getting a Photo from a Contact
But I dont know how to put those together. It would be great if someone could help me putting it together.
Thank you very much!

Try the following code:
public static ArrayList<File> getListFiles(File parentDir) {
ArrayList<File> inFiles = new ArrayList<File>();
File[] files;
files = parentDir.listFiles();
if (files != null) {
for (File file : files) {

file.getName().endsWith(".gif")) {
if (!inFiles.contains(file)) inFiles.add(file);
if (!inFiles.contains(file)) inFiles.add(file);
}
}
}
return inFiles;
}
Use :
private static final String WHATSAPP_STATUSES_LOCATION =
"/storage/emulated/0/yourfoldername";
getListFiles(new File(WHATSAPP_STATUSES_LOCATION));

A bit late but posting for future viewers
Uri uri= MediaStore.Video.Media.EXTERNAL_CONTENT_URI;
String condition=MediaStore.Video.Media.DATA +" like?";
String[] selectionArguments=new String[]{"%FolderPath%"};
String sortOrder = MediaStore.Video.Media.DATE_TAKEN + " DESC";
String[] projection = { MediaStore.Images.Media._ID, MediaStore.Images.Media.BUCKET_ID,
MediaStore.Images.Media.BUCKET_DISPLAY_NAME,MediaStore.Images.Media.DATA };
Cursor cursor = getContentResolver().query(uri,projection, condition, selectionArguments, sortOrder);
int idColumn = cursor.getColumnIndexOrThrow(MediaStore.Images.Media._ID);
int pathColumn=cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
if(cursor!=null){
ContentResolver resolver = getApplicationContext().getContentResolver();
while(cursor3.moveToNext()){
String filePath=cursor.getString(pathColumn);
int id = cursor.getInt(idColumn );
Bitmap thumbNail = bitmap=MediaStore.Video.Thumbnails.getThumbnail(resolver, imageID,
MediaStore.Video.Thumbnails.MICRO_KIND, null);
}
}

use this code`
String path = Environment.getExternalStorageDirectory().toString()+"/Your Folder/";`
File f = new File(path);
File file[] = f.listFiles();
for (int i=0; i < file.length; i++)
{
Log.d("Files", "FileName:" + file[i].getName());
}
above code give you all file from the folder ,after you can separate
using it's extension

how to show thumbimage in gridview from sdcard

// Create the cursor pointing to the SDCard
Cursor cursor = managedQuery( MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
projection, // Which columns to return
null, // Return all rows
null,
orderBy);
int columnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Media._ID);
int size = cursor.getCount();
// If size is 0, there are no images on the SD Card.
if (size == 0) {
//No Images available, post some message to the user
}
int imageID = 0;
for (int i = 0; i < size; i++) {
cursor.moveToPosition(i);
imageID = cursor.getInt(columnIndex);
uri = Uri.withAppendedPath(MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, "" + imageID);
try {
bitmap = BitmapFactory.decodeStream(getContentResolver().openInputStream(uri));
if (bitmap != null) {
newBitmap = Bitmap.createScaledBitmap(bitmap, 86, 96, true);
bitmap.recycle();
if (newBitmap != null) {
publishProgress(new LoadedImage(newBitmap));
}
}
} catch (IOException e) {
