android have 8000 contacts render in Application

android have 8000 contacts render in Application - android

Application need to read the phonebook contacts and show it to the user, have more than 8000 contacts on the phone.
Problem is it stuck for very long time while rendering all contacts on the screen.
Please suggest best way to accomplish this task. thanks
Main Method:

return view;
}
public ArrayList<ImportContactModel> getCheckList(){
ArrayList<ImportContactModel> tempList = new ArrayList<ImportContactModel>();
for(int i=0;i<list.size();i++){
if(list.get(i).isSelected()){
tempList.add(list.get(i));
LogUtils.d(""+list.get(i).getContactName());
}
}
return tempList;
}
}
So it just shows Loading screen for huge amount of time..

You don't have to fetch all contacts to display them. AsyncTask has publishProgress method. I'm not experienced with Cursor class, since I prefer ORM for that, so I'll write in pseudo code, you'll have to adapt it yourself.
//in AsyncTask
protected Void doInBackground(params){
while(cursor.moveToNext()){
contactInfo = createContact(currentCursorValue);
publishProgress(contactInfo);
}
}
onProgressUpdate(contactInfo){
if(adapter==null){
//first time adapter setup
}
adapter.add(contactInfo);
adapter.notifyDataSetChanged();
}
This way, every time you pull a record from Db, you publish it, and items are added continuously. User won't notice any delay, unless he tries searching for not yet existing items, or you want to implement that big pop up letter for fast scroll. Still, above code is not very effective, since publishing the progress every .001 second or so, is not very smart, so you can either publish every 20 results, or publish them every second, up to you.

Retrieve birthday of specific contacts

Contact list are retrieved from Contacts and displayed in listView. When a single contact is clicked from listview it starts a new activity i.e DetailActivity.java(code provided below). I need to show the clicked contact's birthday in DetailActivity's TextView field. How to do it?
MainActivity.java
public class MainActivity extends AppCompatActivity {
ListView listView1 ;
ArrayList<String> nameArray, phoneArray;
ArrayAdapter<String> arrayAdapter;
Cursor cursor, birthdayCur ;
String name, birthday ;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main1);
listView1 = (ListView)findViewById(listView);
nameArray = new ArrayList<String>();
GetContactsIntoArrayList();
arrayAdapter = new ArrayAdapter<String>(
MainActivity.this,
R.layout.contact_items,
textView, nameArray
);
listView1.setAdapter(arrayAdapter);
listView1.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapter, View view, int position, long arg) {
String data = (String) adapter.getItemAtPosition(position);
Intent appInfo = new Intent(MainActivity.this, DetailActivity.class);
appInfo.putExtra("data", data);
startActivity(appInfo);
}
});
}
public void GetContactsIntoArrayList(){
cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null, null, null);
while (cursor.moveToNext()) {
name = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
nameArray.add(name);
}
cursor.close();
String where = ContactsContract.CommonDataKinds.Event.TYPE + "=" + ContactsContract.CommonDataKinds.Event.TYPE_BIRTHDAY;
birthdayCur = getContentResolver().query(ContactsContract.Data.CONTENT_URI, null, where, null, null);
if (birthdayCur.getCount() > 0) {
while (birthdayCur.moveToNext()) {
birthday = birthdayCur.getString(birthdayCur.getColumnIndex(ContactsContract.CommonDataKinds.Event.START_DATE));
phoneArray.add(birthday);
}
}
birthdayCur.close();
}
DetailActivity.java
public class DetailActivity extends AppCompatActivity {
TextView tv1, tv2;
String data;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_detail);
Intent i = getIntent();
data = i.getStringExtra("data");
tv1 = (TextView) findViewById(R.id.name);
tv1.setText(data);
}

you can get the birthday date of contacts, try this:
ContentResolver cr = getContentResolver();
Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
if (cur.getCount() > 0) {
while (cur.moveToNext()) {
String id = cur.getString(cur.getColumnIndex(ContactsContract.Contacts._ID));
String name = cur.getString(cur.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
ContentResolver bd = getContentResolver();
Cursor bdc = bd.query(android.provider.ContactsContract.Data.CONTENT_URI, new String[] { Event.DATA }, android.provider.ContactsContract.Data.CONTACT_ID+" = "+id+" AND "+Data.MIMETYPE+" = '"+Event.CONTENT_ITEM_TYPE+"' AND "+Event.TYPE+" = "+Event.TYPE_BIRTHDAY, null, android.provider.ContactsContract.Data.DISPLAY_NAME);
if (bdc.getCount() > 0) {
while (bdc.moveToNext()) {
String birthday = bdc.getString(0);
// now "id" is the user's unique ID, "name" is his full name and "birthday" is the date and time of his birth
}
}
}
}
cur.close();

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.
//__________________________ALBUM_ART_______________________________________________________
int id = cursor.getColumnIndex(MediaStore.Audio.Media._ID);
long songId = cursor.getLong(id);
String string = getAlbumArtPath(context, songId);
if(string!=null) {
Picasso.with(context)
.load(new File(string))
.into(viewHolder.albumArt);
}else{
viewHolder.albumArt.setImageResource(R.drawable.placeholder);
}
}
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;
}

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());
}

Android cursor return empty contacts

I need to get all contacts that have at least a phone number. Android contacts may be picked from many accounts like gmail,skype,vibe etc. I made the classes i need to get the contacts i need.

Contacts getting fetched twice

I am using the below code in my app to fetch contacts in the listview but its displaying the same contact two times.
Cursor phones = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null,null,null, ContactsContract.Contacts.DISPLAY_NAME + " ASC");
while (phones.moveToNext())
{
String name1=phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String phoneNumber = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
// System.out.println(".................."+name1);
}
I think its getting the sim + internal contacts. Is there any way to get contacts through internal storage only?

I used this method, and it show only one time
// declear two array list
List<String> name1 = new ArrayList<String>();
List<String> phno1 = new ArrayList<String>();
getAllContacts(this.getContentResolver());
// call this where you want to get contacts and give permission in mainfest
public void getAllContacts(ContentResolver cr) {
Cursor phones = cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null,
null, null);
while (phones.moveToNext()) {
String name = phones
.getString(phones
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String phoneNumber = phones
.getString(phones
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
// Bitmap bitmap=-
// phones.getBlob(ContactsContract.CommonDataKinds.Phone.)
System.out.println("" + phoneNumber);
name1.add(name);
phno1.add(phoneNumber);
}
phones.close();
}
// set in adaptr like this
class MyAdapter extends BaseAdapter {
LayoutInflater mInflater;
TextView tv1, tv;
CheckBox cb;
MyAdapter() {
mInflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
#Override
public int getCount() {
return name1.size();
}
#Override
public Object getItem(int position) {
return position;
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(final int position, View convertView,
ViewGroup parent) {
View vi = convertView;
if (convertView == null)
vi = mInflater.inflate(R.layout.friends_addmobile_contacts,
null);
TextView tv = (TextView) vi.findViewById(R.id.tvMcontactname);
tv1 = (TextView) vi.findViewById(R.id.tvMcontactphoneno);
tv.setText("" + name1.get(position));
tv1.setText("" + phno1.get(position));
// tv1.setText("Phone No :" + phno1.get(position));
return vi;
}
}
// call this method
MyAdapter ma = new MyAdapter();
lvmobilecontacts.setAdapter(ma);
