Getting a Photo from a Contact

Alright, I'm just trying to learn about using Contact information, but I'm a bit stuck. I would like to be able to display a picture for the contact. Using the following code that I have, how would I be able to put the photo for the contact in the ImageView in contact_entry?

ListView contacts_list = (ListView) findViewById(R.id.contacts_list);

// Gets the URI of the db
Uri uri = ContactsContract.Contacts.CONTENT_URI;
// What to grab from the db
String[] projection = new String[] {
ContactsContract.Contacts._ID,
ContactsContract.Contacts.DISPLAY_NAME,
ContactsContract.Contacts.PHOTO_ID
};

String sortOrder = ContactsContract.Contacts.DISPLAY_NAME + " COLLATE LOCALIZED ASC";

Cursor cursor = managedQuery(uri, projection, null, null, sortOrder);

String[] fields = new String[] {
ContactsContract.Data.DISPLAY_NAME
};

int[] values = {
R.id.contactEntryText
};

SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, R.layout.contact_entry, cursor,
fields, values);
contacts_list.setAdapter(adapter);


contact_entry.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="54px">
<ImageView
android:id="@+id/contactPhoto"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:src="@drawable/ic_contact_picture_3"/>
<TextView
android:text="@+id/contactEntryText"
android:id="@+id/contactEntryText"
android:layout_width="fill_parent"
android:layout_height="wrap_content"/>
</LinearLayout>

Probably this will help you(contact is identified by getId()):

/**
 * @return the photo URI
 */
public Uri getPhotoUri() {
    try {
        Cursor cur = this.ctx.getContentResolver().query(
                ContactsContract.Data.CONTENT_URI,
                null,
                ContactsContract.Data.CONTACT_ID + "=" + this.getId() + " AND "
                        + ContactsContract.Data.MIMETYPE + "='"
                        + ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE + "'", null,
                null);
        if (cur != null) {
            if (!cur.moveToFirst()) {
                return null; // no photo
            }
        } else {
            return null; // error in cursor process
        }
    } catch (Exception e) {
        e.printStackTrace();
        return null;
    }
    Uri person = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, Long
            .parseLong(getId()));
    return Uri.withAppendedPath(person, ContactsContract.Contacts.Photo.CONTENT_DIRECTORY);
}

Usage is:

Uri u = objItem.getPhotoUri();
if (u != null) {
        mPhotoView.setImageURI(u);
} else {
        mPhotoView.setImageResource(R.drawable.ic_contact_picture_2);
}
