Get Contact List in Android Application

Hello friends,
Today we are going to learn about one example. Into this we can fetch all the contact from Addressbook and print log in android Logcat. It's important think in android we can see much more app has this type of contact list. so Let's take an example.

 First we need to add one permission in our project AndroidMainfest.xml file.

<uses-permission android:name="android.permission.READ_CONTACTS" />

MainActivity.java

public class MainActivity extends AppCompatActivity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        displayContacts();
    }
    private void displayContacts() {
        ContentResolver cr = getContentResolver();
        Cursor cursor = cr.query(ContactsContract.Contacts.CONTENT_URI,
                null, null, null, null);
        if (cursor.getCount() > 0) {
            while (cursor.moveToNext()) {
                String id = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts._ID));
                String name = cursor.getString(cursor.getColumnIndex(ContactsContract.Contacts.DISPLAY_NAME));
                if (Integer.parseInt(cursor.getString(
                        cursor.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
                    Cursor Cur = cr.query(
                            ContactsContract.CommonDataKinds.Phone.CONTENT_URI,
                            null,
                            ContactsContract.CommonDataKinds.Phone.CONTACT_ID + " = ?",
                            new String[]{id}, null);
                    while (Cur.moveToNext()) {
                        String phoneNomber = Cur.getString(Cur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
                        Log.w("Contact List","Name: " + name + ", Phone No: " + phoneNomber);
                    }
                    Cur.close();
                }
            }
        }
    }
}
