In my android application I need to show the contact list in listview .. but when I am displaying contacts are repeating ..I am giving my code below if anyone can suggest what change I need to give please help... iam giving my code below
Cursor c = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);
while (c.moveToNext())
{
String contactName = c
.getString(c
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String phNumber = c
.getString(c
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
boolean retval2 = contacts1.contains(contactName);
if (retval2 == false)
{
Contact con = new Contact(c.getString(c
.getColumnIndex(Contacts.DISPLAY_NAME)), c.getString(c
.getColumnIndex(Phone.NUMBER)));
contacts.add(con);
contacts1.add(contactName);
}
}
listView.setAdapter(new ContactsAdapter(this, contacts));
public class Contact
{
private String name;
private String mobile;
public Contact(String name, String mobile)
{
super();
this.name = name;
this.mobile = mobile;
}
public String getName()
{
return name;
}
public void setName(String name)
{
this.name = name;
}
public String getMobile()
{
return mobile;
}
public void setMobile(String mobile)
{
this.mobile = mobile;
}
}
This might help removing duplicates
if(!contacts.contains(con))
{
contacts.add(con);
}

I am working with android device contacts. if android device contacts more than five thousand,Fetch data from contacts take too much time with blank screen. I have used bellow code to fetch data
private void fetchContacts1() {
String order = ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC";
Cursor cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, order);
while (cursor.moveToNext()) {
String name = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME));
String phonenumber = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
}
cursor.close();
}
I show all the contacts to recycle view.There are some devices which has more than ten thousand contacts. can you suggest me how to handle it.
Use the Async task to load your contacts in the background. after loading for first-time store your list of contacts to your local database
below following links may help you

class ContactLoader extends AsyncTask<Void, Void, List<Contact>> {
#Override
protected void onPreExecute() {
super.onPreExecute();
//visible your progress bar here
}
#Override

List<Contact> contacts = new ArrayList<>();
String order = ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " ASC";
Cursor cursor = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, order);

String phonenumber = cursor.getString(cursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
contacts.add(new Contact(name, phonenumber));
}
cursor.close();
return contacts;

I can't find any solutions to read contacts from Android and save them in Realm. Anyone done that before?
I know that I will have to use Contacts Provider, but this is all I know. AFAIK, Realm doesn't support Cursor so...what else?

public class RealmContract extends RealmObject {

EDIT: Refer to OP's other question for reading contact data reliably (because there's something up with the Contact LOOKUP_ID and making sure the IDs are correct): Obtaining contacts from content provider without duplicates or invalid contacts, and save to Realm
You can create a Model Class to store desired data from contact
then using Cursor get data and set data in model class.
Save the cursor data in list of model object.
Then insert all model object in single transaction as per object transaction has overhead and slow our app

I'm using ORMLite (v4.48) with my Android app. I have the table "Contact" which can contain multiple "Email" (ForeignCollectionField) and one "Personal" (DatabaseField) object. When I get the Contact object from the database I would like to automatically get (or lazy load) the Personal object which has the same Contact ID.
It already automatically gets the Email objects which I can access. But for some reason the Personal object is always "null" even though there is an entry in the Personal table.
Here are my classes:
#DatabaseTable(tableName = "Contact", daoClass = ContactDao.class)
public class Contact {
#DatabaseField(generatedId = true, columnName = PersistentObject.ID)
int id;
#DatabaseField(index = true)
String contactName;
#ForeignCollectionField(eager = false)
ForeignCollection<Email> emails;
#DatabaseField(foreign = true)
public Personal personal;
public ForeignCollection<Email> getEmails() {
return emails;
}
public void setEmails(ForeignCollection<Email> emails) {
this.emails = emails;
}
public Personal getPersonal() {
return personal;
}
public void setPersonal(Personal personal) {
this.personal = personal;
}
...
}
And
#DatabaseTable(tableName = "Email", daoClass = EmailDao.class)
public class Email {
#DatabaseField(generatedId = true, columnName = PersistentObject.ID)
int id;
#DatabaseField(foreign = true, foreignAutoRefresh = true, columnName = PersistentObject.CONTACT_ID_FIELD_NAME) // contact_id
Contact contact;
#DatabaseField
String emailType;
#DatabaseField(canBeNull = false)
String email;
public Email() {
}
public Email(int id, Contact Contact, String emailType, String email) {
this.id = id;
this.contact = contact;
this.emailType = emailType;
this.email = email;
}
public int getId() {
return id;
}
public Contact getContact() {
return contact;
}
public void setContact(Contact contact) {
this.contact = contact;
}
public String getEmailType() {
return emailType;
}
public void setEmailType(String emailType) {
this.emailType = emailType;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
...
}
and
#DatabaseTable(tableName = "Personal", daoClass = PersonalDao.class)
public class Personal {
#DatabaseField(generatedId = true, columnName = PersistentObject.ID)
int id;
#DatabaseField(foreign = true, foreignAutoRefresh = true, columnName = PersistentObject.CONTACT_ID_FIELD_NAME)
Contact contact;
#DatabaseField
int age;
#DatabaseField
int weight; // in grams
#DatabaseField
int height; // in cm
public Personal() {
}
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public Contact getContact() {
return contact;
}
public void setContact(Contact contact) {
this.contact = contact;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public int getWeight() {
return weight;
}
public void setWeight(int weight) {
this.weight = weight;
}
public int getHeight() {
return height;
}
public void setHeight(int height) {
this.height = height;
}
}
I'm getting the data from the database like this:
QueryBuilder<Contact, Integer> queryBuilder = mContactDao.queryBuilder();
queryBuilder.orderBy("lastViewed", false);
queryBuilder.limit(limit);
PreparedQuery<Contact> preparedQuery = queryBuilder.prepare();
List<Contact> contactList = mContactDao.query(preparedQuery);
that all works well so far.
Then further down the code I can access the Email objects like this:
ForeignCollection<Email> emails = contact.getEmails();
Iterator<Email> iter = emails.iterator();
while (iter.hasNext()) {
Email iAddress = iter.next();
Log.d(TAG, "EMAIL: " + iAddress.getEmail());
Log.d(TAG, "EMAIL TYPE: " + iAddress.getEmailType());
}
Which also works perfectly. Only if I want to access the Personal object I always get NULL.
Personal personal = contact.getPersonal(); // is always NULL
I can't figure out why that is. Do I manually need to add a JOIN in the query builder? I thought it would also lazily load the data once I access it with getPersonal() like it does with getEmails()?
You did not show how entity instances are created, but i assume Personal is created after Contact has been inserted. If that is a case, then after inserting Personal you should do contact.setPersonal(personal), and contactDao.update(contact) - that way personal_id will be stored in contact row
I am trying to implement search on user input. The serach results will be shown after searching the relevant option from database.
I have made this method to display the results
public Cursor getBooksBySearch(String query) {
// TODO Auto-generated method stub
String[] args={query};
return(getReadableDatabase().rawQuery("SELECT _id,chapter FROM chapters WHERE chapter LIKE '%" + query + "%", args));
}
Here the query is coming from an activity SearchResultAcitvity.java
Intent intent = getIntent();
if (Intent.ACTION_SEARCH.equals(intent.getAction())) {
String query = intent.getStringExtra(SearchManager.QUERY);
ListView myListView = (ListView)findViewById(R.id.txt_query);
dbBookHelper = new BooklistHelper(this);
ourCursor = dbBookHelper.getBooksBySearch(query);
startManagingCursor(ourCursor);
adapter = new BookAdapter(ourCursor);
myListView.setAdapter(adapter);
myListView.setOnItemClickListener(onListClick);
}
I want to match this coming query string to get the results from my chapter table.
Can I just match the query string m getting in String query = intent.getStringExtra(SearchManager.QUERY) with the data in my database.
Using list view to display.
Please help me in this.
Let me know if you want more information
Thanks in Advance :)
This will return list of data search by keyword
public ArrayList<ObjectType> getSearchData(String keyword)
{
ArrayList<ObjectType> objectTypeList = new ArrayList<ObjectType>();
SQLiteDatabase db = getWritableDatabase();
String checkEntry="SELECT id,firstname,lastname FROM abc_table WHERE firstname like '%"+ keyword +"%'" +" or "+ "p.lastname like '%"+ keyword +"%'";
Cursor cursor = db.rawQuery(checkEntry, null);
try
{
//If entry exist then update
if (cursor.moveToFirst())
{
do
{
ObjectType objectType = new ObjectType();
int PID=cursor.getInt(0);
String fname = cursor.getString(1);
String LastName = cursor.getString(2);
objectType.setFirstName(fname);
objectType.setLastName(LastName);
objectTypeList.add(objectType);
}
while(cursor.moveToNext());
}
}
finally
{
if(cursor != null)
cursor.close();
}
return objectTypeList;
}
ObjectType is class
public class ObjectType {
int id;
String firstName;
String lastName;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
}
Hope this ll help you.. :)
