Setelah bisa menambah Contacts pada Phone Book Android, kali ini penulis ingin membagi cara membaca Contacts secara pemrograman di Android. Program ini secara sederhana akan membaca semua Contacts dan menampilkannya sebagai Message Box (Toast).
Program utama kita letakkan di MainActivity
MainActivity.java
package my.amijaya.readcontacts;
import android.app.Activity;
import android.content.ContentResolver;
import android.database.Cursor;
import android.net.Uri;
import android.os.Bundle;
import android.provider.ContactsContract;
import android.widget.TextView;
import android.widget.Toast;
public class MainActivity extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
TextView contactView = (TextView) findViewById(R.id.con);
//Cursor cursor = getContacts();
//while (cursor.moveToNext()) {
//String displayName = cursor.getString(cursor.getColumnIndex(ContactsContract.Data.DISPLAY_NAME));
//contactView.append("Name: ");
//contactView.append(displayName);
//contactView.append("\n");
//}
/* **
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.CommonDataColumns.DATA));
}
emails.close();
cursor.close();
}
** */
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));
String all = id + " " + name + " ";
if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) {
System.out.println("name : " + name + ", ID : " + id);
Toast.makeText(this, "name : " + name + ", ID : " + id, Toast.LENGTH_LONG).show();
// get the phone number
Cursor pCur = cr.query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI,null,
ContactsContract.CommonDataKinds.Phone.CONTACT_ID +" = ?",
new String[]{id}, null);
while (pCur.moveToNext()) {
String phone = pCur.getString(
pCur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER));
System.out.println("phone" + phone);
Toast.makeText(this, "phone : " + phone, Toast.LENGTH_LONG).show();
all = all + phone + " ";
}
pCur.close();
// get email and type
Cursor emailCur = cr.query(
ContactsContract.CommonDataKinds.Email.CONTENT_URI,
null,
ContactsContract.CommonDataKinds.Email.CONTACT_ID + " = ?",
new String[]{id}, null);

}
emailCur.close();
// Get note.......
String noteWhere = ContactsContract.Data.CONTACT_ID + " = ? AND " + ContactsContract.Data.MIMETYPE + " = ?";
String[] noteWhereParams = new String[]{id,
ContactsContract.CommonDataKinds.Note.CONTENT_ITEM_TYPE};
Cursor noteCur = cr.query(ContactsContract.Data.CONTENT_URI, null, noteWhere, noteWhereParams, null);
if (noteCur.moveToFirst()) {
String note = noteCur.getString(noteCur.getColumnIndex(ContactsContract.CommonDataKinds.Note.NOTE));
System.out.println("Note " + note);
all = all + note + " ";
}
noteCur.close();
//Get Postal Address....
String addrWhere = ContactsContract.Data.CONTACT_ID + " = ? AND " + ContactsContract.Data.MIMETYPE + " = ?";
String[] addrWhereParams = new String[]{id,
ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_ITEM_TYPE};
// Cursor addrCur = cr.query(ContactsContract.Data.CONTENT_URI,
// null, null, null, null);
Cursor addrCur = cr.query(ContactsContract.Data.CONTENT_URI,
null, addrWhere, addrWhereParams, null);
while(addrCur.moveToNext()) {
String poBox = addrCur.getString(
addrCur.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.POBOX));
String street = addrCur.getString(
addrCur.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.STREET));
String city = addrCur.getString(
addrCur.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.CITY));
String state = addrCur.getString(
addrCur.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.REGION));
String postalCode = addrCur.getString(
addrCur.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.POSTCODE));
String country = addrCur.getString(
addrCur.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.COUNTRY));
String type = addrCur.getString(
addrCur.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.TYPE));
// Do something with these....
all = all + street + " " + city + " ";
}
addrCur.close();
// Get Instant Messenger.........
String imWhere = ContactsContract.Data.CONTACT_ID + " = ? AND " + ContactsContract.Data.MIMETYPE + " = ?";
String[] imWhereParams = new String[]{id,
ContactsContract.CommonDataKinds.Im.CONTENT_ITEM_TYPE};
Cursor imCur = cr.query(ContactsContract.Data.CONTENT_URI,
null, imWhere, imWhereParams, null);
if (imCur.moveToFirst()) {
String imName = imCur.getString(
imCur.getColumnIndex(ContactsContract.CommonDataKinds.Im.DATA));
String imType;
imType = imCur.getString(
imCur.getColumnIndex(ContactsContract.CommonDataKinds.Im.TYPE));
}
imCur.close();
// Get Organizations.........
String orgWhere = ContactsContract.Data.CONTACT_ID + " = ? AND " + ContactsContract.Data.MIMETYPE + " = ?";
String[] orgWhereParams = new String[]{id,
ContactsContract.CommonDataKinds.Organization.CONTENT_ITEM_TYPE};
Cursor orgCur = cr.query(ContactsContract.Data.CONTENT_URI,
null, orgWhere, orgWhereParams, null);
if (orgCur.moveToFirst()) {
String orgName = orgCur.getString(orgCur.getColumnIndex(ContactsContract.CommonDataKinds.Organization.DATA));
String title = orgCur.getString(orgCur.getColumnIndex(ContactsContract.CommonDataKinds.Organization.TITLE));
all = all + orgName + " " + title + " ";
}
orgCur.close();
}
//Toast.makeText(this, all, Toast.LENGTH_LONG).show();
}
}
}
/*private Cursor getContacts() {
// Run query
Uri uri = ContactsContract.Contacts.CONTENT_URI;
String[] projection = new String[] { ContactsContract.Contacts._ID, ContactsContract.Contacts.DISPLAY_NAME };
String selection = ContactsContract.Contacts.IN_VISIBLE_GROUP + " = ‘" + ("1") + "’";
String[] selectionArgs = null;
String sortOrder = ContactsContract.Contacts.DISPLAY_NAME+ " COLLATE LOCALIZED ASC";
return managedQuery(uri, projection, selection, selectionArgs, sortOrder);
}*/
}
Kemudian tampilannya kita pakai saja tampilan default, karena hanya untuk mengetes operasi baca Contacts secara sederhana saja.
main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:id ="@+id/con"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
/>
</LinearLayout>
Jangan lupa untuk memberikan permission Read Contact, klo perlu Write Contact sekalian di Android Manifest.
AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="my.amijaya.readcontacts"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".MainActivity"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
<uses-sdk android:minSdkVersion="8" />
<uses-permission android:name="android.permission.WRITE_CONTACTS"/>
<uses-permission android:name="android.permission.READ_CONTACTS"/>
</manifest>
