SQLite DB Query

I am building an SQLite DB. One of the tables consists of 2 columns - term and definition.
My question is : How can I query the DB, in order the pair term-definition to be returned in order to be able to insert the data in the activity after that (the term and data are in ExpandableListView, the term is the Key, the data - the value).
Here is the code of the data source so far:
public class TermDataSource extends DAO {
//constants
public static final String TABLE_NAME = "terms";
public static final String TERM = "term";
public static final String DEFINITION = "definition";
//columns in the table
public static final int FIELD_ID_ID = 0;
public static final int FIELD_ID_TERM = 1;
public static final int FIELD_ID_DEFINITION = 2;
public TermDataSource (Context context){
super(context);
}
private String [] selectFields = {_ID, TERM, DEFINITION};
public Cursor getTermsData(){
SQLiteDatabase db = this.getReadableDatabase();
Cursor cursor = db.query(TABLE_NAME, selectFields, null, null, null, null, null);
return cursor;
}
public List<Term> getTerms(){
SQLiteDatabase db = this.getReadableDatabase();
Cursor cursor = db.query(TABLE_NAME, selectFields, null, null, null, null, null);
List<Term> terms = new ArrayList<Term>();
if(cursor!=null){
Term term = null;
while(cursor.moveToNext()){
term = getTermFromCursor(cursor);
terms.add(term);
}
cursor.close();
}
db.close();
return terms;
}
private Term getTermFromCursor (Cursor cursor){
Term term = new Term();
term.setTermId(cursor.getInt(FIELD_ID_ID));
term.setTerm(cursor.getString(FIELD_ID_TERM));
term.setDefinition(cursor.getString(FIELD_ID_DEFINITION));
return term;
}
}

Create a folder res>raw and put youfile.csv in that folder.
Use this method to insert data in Your Database from CSV file.
public void insertCSVData(Activity activity, InputStream is, String tableName) {
String colunmNames = null, str1 = null;
open();
try {
BufferedReader buffer = new BufferedReader(new InputStreamReader(is));
String line = "";
String str2 = ");";
db.beginTransaction();
int i = 0;
while ((line = buffer.readLine()) != null) {
i++;
if (i == 1) {
colunmNames = line;
str1 = "INSERT INTO " + tableName + " (" + colunmNames + ") values (";
} else {
StringBuilder sb = new StringBuilder(str1);
String[] str = line.split(",");
for (int h = 0; h < str.length; h++) {
if (h == str.length - 1) {
sb.append("'" + str[h] + "'");
} else {
sb.append("'" + str[h] + "',");
}
}
sb.append(str2);
db.execSQL(sb.toString());
}
}
db.setTransactionSuccessful();
db.endTransaction();
} catch (Exception e) {
close();
e.printStackTrace();
}
close();
}
Call this method by the below code :
insertCSVData(Activity.this, getResources().openRawResource(R.raw.yourfile),"Your Table Name");

Load different values from a database column

How I can get a different values from a column with the same name (like the photo)?
In the photo, "test" have a 3 differents values, how I can load them to a ListView or a Spinner?
I have this code, works, but don't get the 3 values, only first value:
MainActivity
public void lookupProduct (View view) {
DatabaseHandler dbHandler = new DatabaseHandler(getApplicationContext());
Name name = dbHandler.findProduct(spinner.getSelectedItem().toString());
Toast.makeText(this, spinner.getSelectedItem().toString(), Toast.LENGTH_LONG).show();
Intent j = new Intent(view.getContext(), SubActivity.class);
Bundle dados = new Bundle();
if (name != null) {
inputLabel.setText(String.valueOf(name.getName()));
values.setText(String.valueOf(name.getValue()));
// Passar para SubActivity
dados.putString("name", String.valueOf(name.getName()));
dados.putString("value", String.valueOf(name.getValue()));
} else {
inputLabel.setText("No Match Found");
dados.putString("name","No Match Found" );
dados.putString("value", "No Match Found");
}
j.putExtras(dados);
startActivity(j);
}
DatabaseHelper
public Name findProduct(String name) {
String query = "Select * FROM " + TABLE_LABELS + " WHERE " + KEY_NAME + " = \"" + name + "\"";
SQLiteDatabase db = this.getWritableDatabase();
Cursor cursor = db.rawQuery(query, null);
Name names = new Name();
if (cursor.moveToFirst()) {
cursor.moveToFirst();
names.setID(Integer.parseInt(cursor.getString(0)));
names.setName(cursor.getString(1));
names.setValue(cursor.getString(2));
cursor.close();
} else {
names = null;
}
db.close();
return names;
}
NameClass
public class Name {
private int _id;
private String _name;
private String _value;
public Name() {
}
public Name(int id, String name, String value) {
this._id = id;
this._name = name;
this._value = value;
}
public Name(String name, String value) {
this._name = name;
this._value = value;
}public String getName() {
return this._name;
}
public String getValue() {
return this._value;
}

Try this
Name names = new Name();
ArrayList<Name > listaName= new ArrayList<>();//create an arraylist of your
custom objects
if (cursor.moveToFirst()) {
do {
names.setID(Integer.parseInt(cursor.getString(0)));
names.setName(cursor.getString(1));
names.setValue(cursor.getString(2));
listaName.add(names);//add your object to arraylist(you were overriding the object.)
} while (cursor.moveToNext());
cursor.close();
//AND ALSO CLOSE DB:
db.close
EDIT 2: Try this and change your --> String Query = "Select * from "+TABLE_NAME;
for ( int i= 1; i< listaName.size(); i++ ) {
System.out.println(listaName.get(i).getName());
}
Your problem:
public Name findProduct(String name) {
String query = "Select * FROM " + TABLE_LABELS + " WHERE " + KEY_NAME + " = \"" + name + "\"";
SQLiteDatabase db = this.getWritableDatabase();
Cursor cursor = db.rawQuery(query, null);
Name names = new Name();
if (cursor.moveToFirst()) {
cursor.moveToFirst(); // this is not necessary because on the top line,
you put it in that position
names.setID(Integer.parseInt(cursor.getString(0)));
names.setName(cursor.getString(1));
names.setValue(cursor.getString(2));
cursor.close(); // You should not close until it is
completely used
} else {
names = null;
}
db.close();
return names;
}
And to read all the cursor is necessary to use a do-while method
If you have any problems, you can ask me again

Though not yet tested, you can try this:
// fetch data from DB
public ArrayList<Name> findProduct(String name) {
String query = "Select * FROM " + TABLE_LABELS + " WHERE " + KEY_NAME + " = \"" + name + "\"";
SQLiteDatabase db = this.getWritableDatabase();
Cursor cursor = db.rawQuery(query, null);
ArrayList<Name> listOfNames= new ArrayList<>();
if (cursor.moveToFirst()) {
do {
listOfNames.add(new Name(Integer.parseInt(cursor.getString(0)), cursor.getString(1), cursor.getString(2)));
} while (cursor.moveToNext());
cursor.close();
db.close
return listOfNames;
}
// add data on spinner
public void addItemsOnSpinner() {
Spinner mSpinner = (Spinner) findViewById(R.id.mSpinner);
ArrayList<String> list = new ArrayList<String>();
for(Name name: findProduct("test")){
list.add(name.getValue());
}
ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this, android.R.layout.simple_spinner_item, list);
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
mSpinner.setAdapter(dataAdapter);
}

Android Development Find Contact [duplicate]

I'm working on Android 2.0 and am trying to receive a list of all contacts.
Since android.provider.Contacts.People is deprecated, I have to use android.provider.ContactsContract, But I can't find a proper example of how to use it (ex: retrieve a list of all contacts on the phonebook).
Anyone knows where to find such an example?

First, ensure that you have added
<uses-permission android:name="android.permission.READ_CONTACTS"/>
to your AndroidManifest.xml file, then you can loop through your phone contacts like this:
Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null);
while (cursor.moveToNext()) {
String contactId = cursor.getString(cursor.getColumnIndex(
ContactsContract.Contacts._ID));
String hasPhone = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
if (Boolean.parseBoolean(hasPhone)) {
// You know it has a number so now query it like this
Cursor phones = getContentResolver().query( ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId, null, null);
while (phones.moveToNext()) {
String phoneNumber = phones.getString(phones.getColumnIndex( ContactsContract.CommonDataKinds.Phone.NUMBER));
}
phones.close();
}
Cursor emails = getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, null, ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = " + contactId, null, null);
while (emails.moveToNext()) {
// This would allow you get several email addresses
String emailAddress = emails.getString(
emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
}
emails.close();
}
cursor.close();
Additionally, you can loop through your contacts and simply get the name and phone number like this:
Cursor people = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
while(people.moveToNext()) {
int nameFieldColumnIndex = people.getColumnIndex(PhoneLookup.DISPLAY_NAME);
String contact = people.getString(nameFieldColumnIndex);
int numberFieldColumnIndex = people.getColumnIndex(PhoneLookup.NUMBER);
String number = people.getString(numberFieldColumnIndex);
}
people.close();
Furthermore, if you need to get things like notes from a contact then you will need to use a different URI, like the following (feel free to use this method):
private String getNote(long contactId) {
String note = null;
String[] columns = new String[] { ContactsContract.CommonDataKinds.Note.NOTE };
String where = ContactsContract.Data.RAW_CONTACT_ID + " = ? AND " + ContactsContract.Data.MIMETYPE + " = ?";
String[] whereParameters = new String[]{Long.toString(contactId), ContactsContract.CommonDataKinds.Note.CONTENT_ITEM_TYPE};
Cursor contacts = getContentResolver().query(ContactsContract.Data.CONTENT_URI, projection, where, whereParameters, null);
if (contacts.moveToFirst()) {
rv = contacts.getString(0);
}
contacts.close();
return note;
}
Notice this time I used not only the contact id but the mime type for the query.

Great to see some useful info, it is frustrating how poorly this important topic is covered by docs and such. After too much hacking about I thought I would share a little code also. The following code is a little prettier and get the same thing done more efficiently.
Uri contactUri = ContactsContract.Contacts.CONTENT_URI;
String[] PROJECTION = new String[] {
ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.Contacts.HAS_PHONE_NUMBER,
};
String SELECTION = ContactsContract.Contacts.HAS_PHONE_NUMBER + "='1'";
Cursor contacts = managedQuery(contactUri, PROJECTION, SELECTION, null, null );
The above chunk of code returns a Cursor that points to the resulting query that only contains those rows that have a phone number. This is nice since you typically have many contacts without numbers. Furthermore, the PROJECTION limits the amount of data that is returned.
String key, value, phoneNumber;
Hashtable contactPhoneInfo = new Hashtable<String, String>();
Uri phoneUri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
String [] PHONES_PROJECTION = new String[] { ContactsContract.CommonDataKinds.Phone.NUMBER };
String PHONE_SELECTION = null;
contacts.moveToFirst();
do{
long contactId = contacts.getLong(idColumnIndex);
PHONE_SELECTION = ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=" + contactId;
Cursor phones = managedQuery(phoneUri,
PHONES_PROJECTION,
null,
null,
ContactsContract.CommonDataKinds.Phone.IS_SUPER_PRIMARY + " DESC");
phones.moveToFirst();
key = phones.getString(0).replaceAll("\\D", "");
value = contacts.getString(nameColumnIndex);
contactPhoneInfo.put(key, value);
}while(contacts.moveToNext());
contacts.close();
}
The above chunk gets the phone number associated with each contact id that has a phone number. I store all the info in a hash table and with a key value of the phone number. I stripped the phone number of all none digit info also. For some reason even though ContactsContract.CommonDataKinds.Phone.HAS_PHONE_NUMBER is valid if you include that in the projection argument it breaks the query, I don't know why and it is frustrating that it does.
The second part of the code above is too slow, all the query calls just bog everything down. The following code is much faster. Just grab all the rows for the phone content and use the contact_ids to sort the data you want.
Cursor phones = managedQuery(phoneUri,
PHONES_PROJECTION,
PHONE_SELECTION,
null,
ContactsContract.CommonDataKinds.Phone.IS_SUPER_PRIMARY + " DESC");
contacts.moveToFirst();
do{
value = "";
key = contacts.getString(idColumnIndex);
contactPhoneInfo.put(key, value);
}while(contacts.moveToNext());
phones.moveToFirst();
Set keySet = contactPhoneInfo.keySet();
idColumnIndex = phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID);
int numColumnIndex = phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
do{
key = phones.getString(idColumnIndex);
if(keySet.contains(key)){
value = phones.getString(numColumnIndex).replaceAll("\\D", "");
contactPhoneInfo.put(key, value);
}
}while(phones.moveToNext());
You end up with a hashtable with all the info you want in it. Of course you could put whatever info you want into the data structure. The second way of doing it is much much faster.

Just want to add, when you are retrieving the contacts you might get a lot of "garbage" contacts - for example some email addresses that a user has at some point send an email to, but are not aggregated... If you want only the contacts visible to the user, as in the Androids own contacts application you need to restrict the selection to only IN_VISIBLE_GROUP.
String where = ContactsContract.Contacts.IN_VISIBLE_GROUP + "= ? ";
String[] selectionArgs = new String[] { "1" };

I think it is important to have the code from this URL http://coderzheaven.com/2011/06/get-all-details-from-contacts-in-android/ on StackOverflow cause at times links like that go down.

I found very easy solution to read contacts. (boring to write code for reading each value so it's good to use wrapper class for contacts)

Put this ....
Cursor phones =
getContentResolver().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 Number=phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
}
Let me know if any issue.

This part wouldn't work for me:
while (phones.moveToNext()) {
String phoneNumber = phones.getString(
phones.getColumnIndex(
ContactsContract.CommonDataKinds.Phone.NUMBER));
}
If I use this, though, it does:
while (phones.moveToNext()) {
String pdata = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DATA));
Log.v("DATA",pdata);
}

You can use "ContactManager" example from android developer's site
(OR)
Go to the location where you have set the path to download android-sdk in your system. In android-sdk-mac_x86/samples/android-10 folder, you can see "ContactManager" example.
I have tried using this example, worked well in my application.

I'm using Samsung Galaxy Note 4, and I donno why none of the above worked for me.
I mixed up some and made this woking..
Cursor people = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);
people.moveToFirst();
while(people.moveToNext()) {
int nameFieldColumnIndex = people.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);
String contact = people.getString(nameFieldColumnIndex);
int numberFieldColumnIndex = people.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DATA);
String number = people.getString(numberFieldColumnIndex);
dbWriter.execSQL("Insert Into ContactsList (ContactName, ContactNumber) Values (" +
"'" + contact.replace("'", "''") + "', '" + number.replace("'", "''") + "')");
}
people.close();

really would appreciate your help

Thanks for your screenshot.Could you please improve your code to this:
}catch(Exception e) {
String error = e.getMessage(); //instead of String error = e.toString();
...
So we can see the actual cause.
Can you please make the "don't works" dialog large? I think some text is being trimmed.
I believe you are trying to parse an empty string "".

How to read contacts on Android 2.0

I'm working on Android 2.0 and am trying to receive a list of all contacts.
Since android.provider.Contacts.People is deprecated, I have to use android.provider.ContactsContract, But I can't find a proper example of how to use it (ex: retrieve a list of all contacts on the phonebook).
Anyone knows where to find such an example?

First, ensure that you have added
<uses-permission android:name="android.permission.READ_CONTACTS"/>
to your AndroidManifest.xml file, then you can loop through your phone contacts like this:
Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI,null, null, null, null);
while (cursor.moveToNext()) {
String contactId = cursor.getString(cursor.getColumnIndex(
ContactsContract.Contacts._ID));
String hasPhone = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER));
if (Boolean.parseBoolean(hasPhone)) {
// You know it has a number so now query it like this
Cursor phones = getContentResolver().query( ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = "+ contactId, null, null);
while (phones.moveToNext()) {
String phoneNumber = phones.getString(phones.getColumnIndex( ContactsContract.CommonDataKinds.Phone.NUMBER));
}
phones.close();
}
Cursor emails = getContentResolver().query(ContactsContract.CommonDataKinds.Email.CONTENT_URI, null, ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = " + contactId, null, null);
while (emails.moveToNext()) {
// This would allow you get several email addresses
String emailAddress = emails.getString(
emails.getColumnIndex(ContactsContract.CommonDataKinds.Email.DATA));
}
emails.close();
}
cursor.close();
Additionally, you can loop through your contacts and simply get the name and phone number like this:
Cursor people = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
while(people.moveToNext()) {
int nameFieldColumnIndex = people.getColumnIndex(PhoneLookup.DISPLAY_NAME);
String contact = people.getString(nameFieldColumnIndex);
int numberFieldColumnIndex = people.getColumnIndex(PhoneLookup.NUMBER);
String number = people.getString(numberFieldColumnIndex);
}
people.close();
Furthermore, if you need to get things like notes from a contact then you will need to use a different URI, like the following (feel free to use this method):
private String getNote(long contactId) {
String note = null;
String[] columns = new String[] { ContactsContract.CommonDataKinds.Note.NOTE };
String where = ContactsContract.Data.RAW_CONTACT_ID + " = ? AND " + ContactsContract.Data.MIMETYPE + " = ?";
String[] whereParameters = new String[]{Long.toString(contactId), ContactsContract.CommonDataKinds.Note.CONTENT_ITEM_TYPE};
Cursor contacts = getContentResolver().query(ContactsContract.Data.CONTENT_URI, projection, where, whereParameters, null);
if (contacts.moveToFirst()) {
rv = contacts.getString(0);
}
contacts.close();
return note;
}
Notice this time I used not only the contact id but the mime type for the query.

Great to see some useful info, it is frustrating how poorly this important topic is covered by docs and such. After too much hacking about I thought I would share a little code also. The following code is a little prettier and get the same thing done more efficiently.
Uri contactUri = ContactsContract.Contacts.CONTENT_URI;
String[] PROJECTION = new String[] {
ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.Contacts.HAS_PHONE_NUMBER,
};
String SELECTION = ContactsContract.Contacts.HAS_PHONE_NUMBER + "='1'";
Cursor contacts = managedQuery(contactUri, PROJECTION, SELECTION, null, null );
The above chunk of code returns a Cursor that points to the resulting query that only contains those rows that have a phone number. This is nice since you typically have many contacts without numbers. Furthermore, the PROJECTION limits the amount of data that is returned.
String key, value, phoneNumber;
Hashtable contactPhoneInfo = new Hashtable<String, String>();
Uri phoneUri = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;
String [] PHONES_PROJECTION = new String[] { ContactsContract.CommonDataKinds.Phone.NUMBER };
String PHONE_SELECTION = null;
contacts.moveToFirst();
do{
long contactId = contacts.getLong(idColumnIndex);
PHONE_SELECTION = ContactsContract.CommonDataKinds.Phone.CONTACT_ID + "=" + contactId;
Cursor phones = managedQuery(phoneUri,
PHONES_PROJECTION,
null,
null,
ContactsContract.CommonDataKinds.Phone.IS_SUPER_PRIMARY + " DESC");
phones.moveToFirst();
key = phones.getString(0).replaceAll("\\D", "");
value = contacts.getString(nameColumnIndex);
contactPhoneInfo.put(key, value);
}while(contacts.moveToNext());
contacts.close();
}
The above chunk gets the phone number associated with each contact id that has a phone number. I store all the info in a hash table and with a key value of the phone number. I stripped the phone number of all none digit info also. For some reason even though ContactsContract.CommonDataKinds.Phone.HAS_PHONE_NUMBER is valid if you include that in the projection argument it breaks the query, I don't know why and it is frustrating that it does.
The second part of the code above is too slow, all the query calls just bog everything down. The following code is much faster. Just grab all the rows for the phone content and use the contact_ids to sort the data you want.
Cursor phones = managedQuery(phoneUri,
PHONES_PROJECTION,
PHONE_SELECTION,
null,
ContactsContract.CommonDataKinds.Phone.IS_SUPER_PRIMARY + " DESC");
contacts.moveToFirst();
do{
value = "";
key = contacts.getString(idColumnIndex);
contactPhoneInfo.put(key, value);
}while(contacts.moveToNext());
phones.moveToFirst();
Set keySet = contactPhoneInfo.keySet();
idColumnIndex = phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID);
int numColumnIndex = phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);
do{
key = phones.getString(idColumnIndex);
if(keySet.contains(key)){
value = phones.getString(numColumnIndex).replaceAll("\\D", "");
contactPhoneInfo.put(key, value);

You end up with a hashtable with all the info you want in it. Of course you could put whatever info you want into the data structure. The second way of doing it is much much faster.

Just want to add, when you are retrieving the contacts you might get a lot of "garbage" contacts - for example some email addresses that a user has at some point send an email to, but are not aggregated... If you want only the contacts visible to the user, as in the Androids own contacts application you need to restrict the selection to only IN_VISIBLE_GROUP.
String where = ContactsContract.Contacts.IN_VISIBLE_GROUP + "= ? ";
String[] selectionArgs = new String[] { "1" };

I think it is important to have the code from this URL http://coderzheaven.com/2011/06/get-all-details-from-contacts-in-android/ on StackOverflow cause at times links like that go down.

I found very easy solution to read contacts. (boring to write code for reading each value so it's good to use wrapper class for contacts)

Put this ....
Cursor phones =
getContentResolver().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 Number=phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
}
Let me know if any issue.

This part wouldn't work for me:
while (phones.moveToNext()) {
String phoneNumber = phones.getString(
phones.getColumnIndex(
ContactsContract.CommonDataKinds.Phone.NUMBER));
}
If I use this, though, it does:
while (phones.moveToNext()) {
String pdata = phones.getString(phones.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DATA));
Log.v("DATA",pdata);
}

You can use "ContactManager" example from android developer's site
(OR)
Go to the location where you have set the path to download android-sdk in your system. In android-sdk-mac_x86/samples/android-10 folder, you can see "ContactManager" example.
I have tried using this example, worked well in my application.

I'm using Samsung Galaxy Note 4, and I donno why none of the above worked for me.
I mixed up some and made this woking..
Cursor people = getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, null, null, null);
people.moveToFirst();
while(people.moveToNext()) {
int nameFieldColumnIndex = people.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);
String contact = people.getString(nameFieldColumnIndex);
int numberFieldColumnIndex = people.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DATA);
String number = people.getString(numberFieldColumnIndex);
dbWriter.execSQL("Insert Into ContactsList (ContactName, ContactNumber) Values (" +
"'" + contact.replace("'", "''") + "', '" + number.replace("'", "''") + "')");
}
people.close();
