I am working with Androids contacts and trying to get particular pieces of data. I can already get emails, phone numbers, their name, etc. However I am having difficulty getting the relationship field.
http://developer.android.com/reference/android/provider/ContactsContract.CommonDataKinds.Relation.html
So my goal is: Given a particular userid (from the contact database on Android), figure out their relation field.
This should work. The idea is to connect search in the Data table but use stuff from CommonDataKinds. This is done in where clause ... Data.MIMETYPE == CommonDataKinds.Relation.CONTENT_ITEM_TYPE. This will get you the row with all the Relation stuff.
import android.database.Cursor;
import android.net.Uri;
import android.provider.ContactsContract.CommonDataKinds.Relation;
import android.provider.ContactsContract.Data;
import android.util.Log;
...
public void logCatTheRelation(long contactId){
Uri uri = Data.CONTENT_URI;
String where = String.format(
"%s = ? AND %s = ?",
Data.MIMETYPE,
Relation.CONTACT_ID);
String[] whereParams = new String[] {
Relation.CONTENT_ITEM_TYPE,
Long.toString(contactId),
};
String[] selectColumns = new String[]{
Relation.NAME,
// add additional columns here
};
Cursor relationCursor = this.getContentResolver().query(
uri,
selectColumns,
where,
whereParams,
null);
try{
if (relationCursor.moveToFirst()) {
Log.d("gizm0", relationCursor.getString(
relationCursor.getColumnIndex(Relation.NAME)));
}
Log.d("gizm0", "sadly no relation ... ");
}finally{
relationCursor.close();
}
}

I want to read a specific SMS in my Inbox. I found on the Internet how to read all the sms in the inbox. That is what I did. Please help me to read just one SMS from a specific number. Thanks
package com.example.liresms;
import android.app.Activity;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.widget.TextView;
public class ReadSMS extends MainActivity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView view = new TextView(this);
Uri uriSMSURI = Uri.parse("content://sms/inbox");
Cursor cur = getContentResolver().query(uriSMSURI, null, null, null,null);
String sms = "";
while (cur.moveToNext()) {
sms += "From :" + cur.getString(2) + " : " + cur.getString(11)+"\n";
}
view.setText(sms);
setContentView(view);
}
}
You're pretty close to already doing it. I suggest you take a look at the arguments for the ContentResolver.query method and pay specific attention to the selection parameter. What you're looking to do is only select messages where a particular column is equal to the number you're looking for...
Something like
Cursor cur = getContentResolver().query(uriSMSURI, null, "from=6159995555", null,null);
I don't know the specific column name off the top of my head, but that should get you started in the right direction...
I am trying to write a query for retrieving data from SQLite database. I wanted to print the result of a query in a text box. So I used a getint() method for the cursor. Below is my code. It does not start in my Android emulator. Is it the correct way to write the query? It is showing no errors.
import android.app.Activity;
import android.os.Bundle;
import android.app.Activity;
import android.database.Cursor;
import android.database.sqlite.*;
import android.os.Bundle;
import android.widget.TextView;
import android.widget.Toast;
public class SQLDemo1Activity extends Activity {
private SQLiteDatabase db;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
try{
db= SQLiteDatabase.openDatabase(
"/data/data/cis493.sqldatabases/databases/multilinguialdatabase.sqlite",
null,
SQLiteDatabase.CREATE_IF_NECESSARY);
db.beginTransaction();
Cursor cursor = db.query(
"colors" /* table */,
new String[] { "ID" } /* columns */,
"English = ?" /* where or selection */,
new String[] { "green" } /* selectionArgs i.e. value to replace ? */,
null /* groupBy */,
null /* having */,
null /* orderBy */
);
int id = cursor.getInt(0);
TextView met = (TextView) findViewById(R.id.t1);
met.setText(id);
db.endTransaction();
db.close();
}
catch(SQLiteException e) {
Toast.makeText(this, e.getMessage(), 1).show();
}
}
}
You need to put cursor.moveToNext() or cursor.moveToFirst() before trying to get the int with getInt(). Put it in an if statement as there may be no results in the cursor.
To write a query in Android Sqllite requires certain parameters like:
// Queries the user dictionary and returns results
mCursor = getContentResolver().query(
URI // The content URI of the words table
mProjection, // The columns to return for each row
mSelectionClause // Selection criteria
mSelectionArgs, // Selection criteria
mSortOrder); // The sort order for the returned rows

I am working on an Android Honeycomb (v3.0) application that has a requirement of displaying ALL contacts stored within the Google account that is registered on the device. One of the problems I am having is that I can only retrieve the contacts that are available within "My Contacts", "Starred in Android", and "Other Contacts". I would also like to be able to retrieve contacts from the "Directory". I believe that the "Directory" section is a feature provided by Google to organizations and companies who wish to provide a directory of all members/employees within their domains to others. Please see the screenshot below:
So far, I have the following line in my manifest file:
<uses-permission android:name="android.permission.READ_CONTACTS" />
I have tried using this code:
Cursor cursor = getContentResolver().query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null);
while (cursor.moveToNext()) {
String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
}
cursor.close();
In my case, "My Contacts" and "Starred in Android" are empty. However, the (1) contact in "Other Contacts" is obtained. The "Directory" contains hundreds of contacts that are not retrieved, though.
My question: Is there any way to make sure that the contacts in the "Directory" are retrieved as well? I know that I can simply copy the contacts over using the web browser and then sync them to the device, but if a new contact is added to the "Directory", I would have to do this manually every time, so this is not a great choice for me. Please advise.
look at the following code
import android.app.Activity;
import android.content.ContentResolver;
import android.database.Cursor;
import android.os.Bundle;
import android.provider.ContactsContract;
public class TestContacts extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
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));
if (("1")
.equals(cur
.getString(cur
.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER)))) {
Cursor pCur = cr.query(
ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID
+ " = ?", new String[] { id }, null);
int i = 0;
int pCount = pCur.getCount();
String[] phoneNum = new String[pCount];
String[] phoneType = new String[pCount];
while (pCur.moveToNext()) {
phoneNum[i] = pCur
.getString(pCur
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
phoneType[i] = pCur
.getString(pCur
.getColumnIndex(ContactsContract.CommonDataKinds.Phone.TYPE));
i++;
}
}
I am trying to get the selected contact number form the phone book when a button is clicked.Could any me please tell me how to get the contact number to the edit text.
Thanks in advance
// using Content Provider you can do it
There are some helper methods, particularly ContentUris.withAppendedId() and Uri.withAppendedPath(), that make it easy to append an ID to a URI. Both are static methods that return a Uri object with the ID added. So, for example, if you were looking for record 23 in the database of people contacts, you might construct a query as follows:
import android.provider.Contacts.People;
import android.content.ContentUris;
import android.net.Uri;
import android.database.Cursor;
// Use the ContentUris method to produce the base URI for the contact with _ID == 23.
Uri myPerson = ContentUris.withAppendedId(People.CONTENT_URI, 23);
// Alternatively, use the Uri method to produce the base URI.
// It takes a string rather than an integer.
Uri myPerson = Uri.withAppendedPath(People.CONTENT_URI, "23");
// Then query for this specific record:
Cursor cur = managedQuery(myPerson, null, null, null, null);
refer this
Given a contact id, I can obtain various contact details (like name, phone, email-id, etc) by making different queries for a each of these fields.
But is there a method to obtain all the details associated with this contact id by making a single query?
Had to change a bit of the tutorial on Content Providers since it referenced deprecated classes, this might help.
import android.provider.ContactsContract.Contacts;
import android.database.Cursor;
// Form an array specifying which columns to return, you can add more.
String[] projection = new String[] {
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.CommonDataKinds.Phone
ContactsContract.CommonDataKinds.Email
};
Uri contacts = ContactsContract.Contacts.CONTENT_LOOKUP_URI;
// id of the Contact to return.
long id = 3;
// Make the query.
Cursor managedCursor = managedQuery(contacts,
projection, // Which columns to return
null, // Which rows to return (all rows)
// Selection arguments (with a given ID)
ContactsContract.Contacts._ID = "id",
// Put the results in ascending order by name
ContactsContract.Contacts.DISPLAY_NAME + " ASC");
