How to load albumArt using AsyncTask in cursor adapter

I have a problem with retrieving albumArt and setting that art to ImageView using AsyncTask in cursor adapter.
When I open my app it looks like this:
Then I scroll down the list and everything is fine(but also if I scroll list not very fast):
Then I scroll list back to the very beggining(not fast) and it looks fine as well:
Probably I do something wrong, I think, so I have question:
Is it possible somehow to solve that problem, I already tried a lot of different ways on how to implement AsyncTask and make it works fine, but in the end of the day it looks always the same.
Below is code for cursor adapter:
public class AllSongsCursorAdapter extends CursorAdapter {
public AllSongsCursorAdapter(Context context, Cursor cursor) {
super(context, cursor, 0);
}
public boolean isCheckBoxVisible;
private AddToFavouritesArray favouritesArray = AddToFavouritesArray.getInstance();
private static class ViewHolder {
CheckBox checkBox;
TextView title;
TextView artist;
ImageView albumArt;
private ViewHolder(View view) {
checkBox = (CheckBox) view.findViewById(R.id.favouritesCheckBox);
title = (TextView) view.findViewById(R.id.title);
artist = (TextView) view.findViewById(R.id.artist);
albumArt = (ImageView) view.findViewById(R.id.albumArt);
}
}
#Override
public View newView(Context context, Cursor cursor, ViewGroup viewGroup) {
View view = LayoutInflater.from(context).inflate(R.layout.song_item, viewGroup, false);
ViewHolder viewHolder = new ViewHolder(view);
view.setTag(viewHolder);
return view;
}
#Override
public void bindView(View view, Context context, final Cursor cursor) {
final ViewHolder viewHolder = (ViewHolder) view.getTag();
if (isCheckBoxVisible) {
viewHolder.checkBox.setVisibility(View.VISIBLE);
} else {
viewHolder.checkBox.setVisibility(View.GONE);
}
final int position = cursor.getPosition();
viewHolder.checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
#Override
public void onCheckedChanged(CompoundButton compoundButton, boolean b) {
if (b) {
favouritesArray.integerArray.add(position);
} else {
favouritesArray.integerArray.remove(Integer.valueOf(position));
}
}
});
int songTitle = cursor.getColumnIndex(MediaStore.Audio.Media.TITLE);
int songArtist = cursor.getColumnIndex(MediaStore.Audio.Media.ARTIST);
String currentTitle = cursor.getString(songTitle);
String currentArtist = cursor.getString(songArtist);
viewHolder.title.setText(currentTitle);
viewHolder.artist.setText(currentArtist);
//__________________________ALBUM_ART_______________________________________________________
viewHolder.albumArt.setTag(cursor.getPosition());
new AsyncTask<ViewHolder, Void, Bitmap>(){
private ViewHolder viewHolder;
#Override
protected Bitmap doInBackground(ViewHolder... viewHolders) {
viewHolder = viewHolders[0];
int id = cursor.getColumnIndex(MediaStore.Audio.Media._ID);
long songId = cursor.getLong(id);
Bitmap albumArt = getAlbumId(context, songId);
return albumArt;
}
#Override
protected void onPostExecute(Bitmap bitmap) {
super.onPostExecute(bitmap);
if(bitmap != null) {
viewHolder.albumArt.setImageBitmap(bitmap);
}else{
viewHolder.albumArt.setImageResource(R.drawable.placeholder);
}
}
}.execute(viewHolder);
}
private Bitmap getAlbumId(Context context, long id) {
Bitmap albumArt = null;
String selection = MediaStore.Audio.Media._ID + " = " + id + "";
Cursor cursor = context.getContentResolver().query(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, new String[]{
MediaStore.Audio.Media._ID, MediaStore.Audio.Media.ALBUM_ID},
selection, null, null);
if (cursor.moveToFirst()) {
long albumId = cursor.getLong(cursor.getColumnIndex(MediaStore.Audio.Media.ALBUM_ID));
albumArt = getAlbumArt(context, albumId);
}
cursor.close();
return albumArt;
}
private Bitmap getAlbumArt(Context context, long albumId) {
Bitmap albumArt = null;
String selection = MediaStore.Audio.Albums._ID + " = " + albumId + "";
Cursor cursor = context.getContentResolver().query(MediaStore.Audio.Albums.EXTERNAL_CONTENT_URI, null, selection, null, null);
if (cursor.moveToFirst()) {
int art = cursor.getColumnIndex(MediaStore.Audio.Albums.ALBUM_ART);
String currentArt = cursor.getString(art);
albumArt = BitmapFactory.decodeFile(currentArt);
}
cursor.close();
return albumArt;
}
}
And yes, sure, without AsyncTask everything works fine except scrolling is very slow.
Thank you in advance!
EDIT
In the end of the day, that's how it works. Thank you very much # Orest Savchak, my up-vote and acceptance for your answer. Thanks a lot.

You should manage your tasks by yourself. Your views are recycled, so, you have one view for different rows, it causes a problem. Most of project use some libraries, that do it automatically for you - much easier, e.g Picasso
Picasso.with(context).load(new File(getAlbumArtPath(context, songId))).into(viewHolder.albumArt);
private String getAlbumArtPath(Context context, long id) {
String selection = MediaStore.Audio.Media._ID + " = " + id + "";
Cursor cursor = context.getContentResolver().query(MediaStore.Audio.Media.EXTERNAL_CONTENT_URI, new String[]{
MediaStore.Audio.Media._ID, MediaStore.Audio.Media.ALBUM_ID},
selection, null, null);
if (cursor.moveToFirst()) {
long albumId = cursor.getLong(cursor.getColumnIndex(MediaStore.Audio.Media.ALBUM_ID));
return getAlbumArt(context, albumId);
}
cursor.close();
return null;
}
private String getAlbumArt(Context context, long albumId) {
String selection = MediaStore.Audio.Albums._ID + " = " + albumId + "";
Cursor cursor = context.getContentResolver().query(MediaStore.Audio.Albums.EXTERNAL_CONTENT_URI, null, selection, null, null);
if (cursor.moveToFirst()) {
int art = cursor.getColumnIndex(MediaStore.Audio.Albums.ALBUM_ART);
return cursor.getString(art);
}
cursor.close();
return null;
}

Android - Cursor - Getting all contacts, but wrong photo pics as well

I'm retrieving all contacts from both Google accounts and the phone.
I don't understand why pics are right for some and wrong for others.
Thanks a lot advance for any help.
This is my code,
List<AddressBookContact> list = new LinkedList<>();
LongSparseArray<AddressBookContact> array = new LongSparseArray<>();
String[] projection = {
ContactsContract.Data.MIMETYPE,
ContactsContract.Data.CONTACT_ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.Contacts.PHOTO_THUMBNAIL_URI,
ContactsContract.CommonDataKinds.Contactables.DATA,
ContactsContract.CommonDataKinds.Contactables.TYPE,
ContactsContract.RawContacts.ACCOUNT_TYPE
};
String selection = ContactsContract.Data.MIMETYPE + " in (?, ?)";
String[] selectionArgs = {
ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE,
ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE,
};
String sortOrder = ContactsContract.Contacts.SORT_KEY_ALTERNATIVE;
Uri uri = null;
if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.JELLY_BEAN_MR2) {
uri = ContactsContract.Data.CONTENT_URI;
}
assert uri != null;
Cursor cursor = context.getContentResolver().query(uri, projection, selection, selectionArgs, sortOrder);
assert cursor != null;
final int idIdx = cursor.getColumnIndex(ContactsContract.Data.CONTACT_ID);
final int nameIdx = cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME);
final int picIdx = cursor.getColumnIndex(ContactsContract.Data.PHOTO_THUMBNAIL_URI);
final int dataIdx = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Contactables.DATA);
final int typeIdx = cursor.getColumnIndex(ContactsContract.CommonDataKinds.Contactables.TYPE);
//final int typeDir = cursor.getColumnIndex(ContactsContract.Directory.ACCOUNT_TYPE);
I loop across the cursor and do some filters to avoid some duplicates
The idea is to gather same contact info under a same contact (object)
while (cursor.moveToNext()) {
long id = cursor.getLong(idIdx);
AddressBookContact addressBookContact = array.get(id);
//if(!cursor.getString(cursor.getColumnIndex(ContactsContract.RawContacts.ACCOUNT_TYPE)).equals("com.google")){
//lastName = cursor.getString(nameIdx);
if(!lastName.toLowerCase().contains(cursor.getString(nameIdx).toLowerCase())){
if(!cursor.getString(nameIdx).toLowerCase().contains("unsub") && !cursor.getString(nameIdx).toLowerCase().contains("noreply")) {
if (!StringUtils.isEmailValid(cursor.getString(nameIdx).toLowerCase())) {
lastName = cursor.getString(nameIdx);
if (addressBookContact == null) {
addressBookContact = new AddressBookContact(id, cursor.getString(nameIdx), context.getResources());
addressBookContact.setImagepath(cursor.getString(picIdx));
array.put(id, addressBookContact);
list.add(addressBookContact);
addressBookContact.setId(id);
}
int type = cursor.getInt(typeIdx);
String data = cursor.getString(dataIdx);
addressBookContact.addEmail(type, data);
}
}
}
else{
if(addressBookContact != null){
int type = cursor.getInt(typeIdx);
String data = cursor.getString(dataIdx);
addressBookContact.addEmail(type, data);
}
}
//}
}
cursor.close();
return list;
}
Based on this, I create an object Contact which is retrieved within a Viewholder
#Override
public void onBindViewHolder(MyContactListViewHolder holder, int position) {
String imagepath = mainInfo.get(position).getImagepath();
if (imagepath != null && !imagepath.isEmpty()) {
ImageView imageView = (ImageView)holder.itemView.findViewById(R.id.imageview_contact_picture);
imageView.setImageURI(Uri.parse(imagepath));
}
else{
String firstLetter = mainInfo.get(position).getName().substring(0,1).toUpperCase();
TextDrawable drawable = TextDrawable.builder()
.buildRound(firstLetter, 0xff3fbfe8);
ImageView image = (ImageView) holder.itemView.findViewById(R.id.imageview_contact_no_picture);
image.setVisibility(View.VISIBLE);
image.setImageDrawable(drawable);
}
holder.textViewShowName.setText(mainInfo.get(position).getName());
}
Code for MyContactListViewHolder
class MyContactListViewHolder extends RecyclerView.ViewHolder{
ImageView imageViewUserImage;
TextView textViewShowName;
MyContactListViewHolder(View itemView) {
super(itemView);
textViewShowName = (TextView) itemView.findViewById(R.id.textview_contact_name);
imageViewUserImage = (ImageView) itemView.findViewById(R.id.imageview_contact_picture);
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
MyBottomSheetDialogFragment bottomSheetDialogFragment = MyBottomSheetDialogFragment.newInstance();
Bundle bundle = new Bundle();
bundle.putParcelable("contact", mainInfo.get(getAdapterPosition()));
bottomSheetDialogFragment.setArguments(bundle);
bottomSheetDialogFragment.show(fragmentManager, null);
}
});
}
}
#Override
public MyContactListViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.contacts_list_item, parent, false);
return new MyContactListViewHolder(v);
}

Don't use findViewById in the onBindViewHolder method. Do it in MyContactListViewHolder (which you are already doing).
Try the following code,
#Override
public void onBindViewHolder(MyContactListViewHolder holder, int position) {
String imagepath = mainInfo.get(position).getImagepath();
if (imagepath != null && !imagepath.isEmpty()) {
holder.imageViewUserImage.setImageURI(Uri.parse(imagepath));
} else{
String firstLetter = mainInfo.get(position).getName().substring(0,1).toUpperCase();
TextDrawable drawable = TextDrawable.builder().buildRound(firstLetter, 0xff3fbfe8);
holder.imageViewUserImage.setVisibility(View.VISIBLE);
holder.imageViewUserImage.setImageDrawable(drawable);
}
holder.textViewShowName.setText(mainInfo.get(position).getName());
}

Display specfic folder videos in a listview with Thumbnails android

I am trying to display video files in listview from folder 'xyz' on sdcard, i have successfully displayed but problem is that it displays all video files stored on sdcard even out of folder 'abc' actually i want only video files stored in folder 'xyz' to be displayed. I am googling since 4 days but didn't find any solution for that. My code is that is showing all videos and working perfectly :

new String[] { id }, null);
cursor.moveToFirst();
long ids = cursor.getLong(cursor.getColumnIndex(MediaStore.Video.Media._ID));
ContentResolver crThumb = getContentResolver();
BitmapFactory.Options options = new BitmapFactory.Options();
options.inSampleSize = 1;
Bitmap curThumb = MediaStore.Video.Thumbnails.getThumbnail(
crThumb, ids, MediaStore.Video.Thumbnails.MICRO_KIND,
options);
holder.thumbImage.setImageBitmap(curThumb);
curThumb = null;
}
return convertView;
}
}
static class ViewHolder {
TextView txtTitle;
TextView txtSize;
ImageView thumbImage;
}

Try this
public static final String[] VIDEO_PROJECTION = {MediaStore.Video.Media._ID, MediaStore.Video.Media.TITLE,
MediaStore.Video.Media.DATA};
public static final Uri VIDEO_SOURCE_URI = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;
Querying the data using the content resolver
CursorLoader cursorLoader = new CursorLoader(getActivity(), VIDEO_SOURCE_URI, VIDEO_PROJECTION, MediaStore.Video.Media.DATA + " like ? ", new String[]{"%FOLDER_NAME%"},
MediaStore.Video.Media.DATA + " COLLATE NOCASE ASC;");
It retrievers all the video files from the FOLDER_NAME. Since there can be one or more folders with a name so it is better to provide absolute path.

sd card video content display (album wise) ( android)

hi guys i am making an android application IN which i have to display all the video contents of the sd card (album wise).....it means when WE WILL LOAD THE APPLICATION only the names of albums should be displayED.... AND when we click on the particular album ITS VIDEOS FILES SHOULD BE DISPLAYED................... i have been able to display the album names BUT THE PROBLEM IS THAT there is duplicate album names (i.e. IF TWO VIDEO files are of same album) then two different albums are being displaying...........so i want all the videos of same album should be in one "album name"........... and on the click of that album name "all its video contents should be displayed"
any help will be appreciated below is the main class (AlbumVideo.class)

wow after so much time spent on the internet at last found the solution for it !!!!!!! it an easy n very short step .,][.....i hope it will be helpful to someone ..........

videolist = (ListView) findViewById(R.id.PhoneVideoList);
videolist.setAdapter(new VideoAdapter(getApplicationContext()));
}
just to add the word "distinct" in the class "album detail"....n it will sort d query according to yourt requirement....

Change the following:
final String[] projection = new String[] {MediaStore.Video.VideoColumns.ALBUM };
into
final String[] projection = new String[]{ "DISTINCT " +MediaStore.Video.VideoColumns.ALBUM};

How to get the images from sdcard and display it in gridview

Actually I tried with this coding it's working fine.i.e., showing all the images perfectly in emulator but coming to mobile it showing repeatedly the same image. I have attached the adapter class also
File file[] = Environment.getExternalStorageDirectory().listFiles();
String strFile = "";
for (int i = 0; i < file.length; i++) {
strFile += file[i].getAbsolutePath() + " :: ";
System.out.println("\n");
}
Log.i("test", strFile);
String[] img = { MediaStore.Images.Thumbnails._ID };
imagecursor = managedQuery(
MediaStore.Images.Thumbnails.EXTERNAL_CONTENT_URI, img, null,
null, MediaStore.Images.Thumbnails.IMAGE_ID + "");
image_column_index = imagecursor
.getColumnIndexOrThrow(MediaStore.Images.Thumbnails._ID);
count = imagecursor.getCount();
imagegrid = (ListView) findViewById(R.id.PhoneImageGrid);
imagegrid.setAdapter(new ImageAdapter(getApplicationContext()));
imagegrid.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v, int position,
long id) {
System.gc();
String[] proj = { MediaStore.Images.Media.DATA };
actualimagecursor = managedQuery(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, proj,
null, null, null);
actual_image_column_index = actualimagecursor
.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
actualimagecursor.moveToPosition(position);
String i = actualimagecursor
.getString(actual_image_column_index);
System.gc();
Intent intent = new Intent(getApplicationContext(),
ViewImage.class);
intent.putExtra("filename", i);
startActivity(intent);
}
});
}
