I created an app to show one contact photo by using his/her number , but I got nothing my result just a blank page , this is my main.xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context=".MainActivity" >
<QuickContactBadge
android:id="@+id/quickContactBadge1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true" />
</RelativeLayout>
and this is my MainActivity.java :
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
String phoneNumber = "XXXXXXXXXXX";
QuickContactBadge badge = (QuickContactBadge) findViewById(R.id.quickContactBadge1);
new QuickContactHelper(this, badge, phoneNumber).addThumbnail();
}
}
and this is QuickContactHelper.java:
public class QuickContactHelper {
private static final String[] PHOTO_ID_PROJECTION = new String[] { ContactsContract.Contacts.PHOTO_ID };
private static final String[] PHOTO_BITMAP_PROJECTION = new String[] { ContactsContract.CommonDataKinds.Photo.PHOTO };
private final QuickContactBadge badge;
private final String phoneNumber;
private final ContentResolver contentResolver;
public QuickContactHelper(final Context context,
final QuickContactBadge badge, final String phoneNumber) {
this.badge = badge;
this.phoneNumber = phoneNumber;
contentResolver = context.getContentResolver();
}
public void addThumbnail() {
final Integer thumbnailId = fetchThumbnailId();
if (thumbnailId != null) {
final Bitmap thumbnail = fetchThumbnail(thumbnailId);
if (thumbnail != null) {
badge.setImageBitmap(thumbnail);
}
}
}
private Integer fetchThumbnailId() {
final Uri uri = Uri.withAppendedPath(
ContactsContract.CommonDataKinds.Phone.CONTENT_FILTER_URI,
Uri.encode(phoneNumber));
final Cursor cursor = contentResolver.query(uri, PHOTO_ID_PROJECTION,
null, null, ContactsContract.Contacts.DISPLAY_NAME + " ASC");
try {
Integer thumbnailId = null;
if (cursor.moveToFirst()) {
thumbnailId = cursor.getInt(cursor
.getColumnIndex(ContactsContract.Contacts.PHOTO_ID));
}
return thumbnailId;
} finally {
cursor.close();
}
}
final Bitmap fetchThumbnail(final int thumbnailId) {
final Uri uri = ContentUris.withAppendedId(
ContactsContract.Data.CONTENT_URI, thumbnailId);
final Cursor cursor = contentResolver.query(uri,
PHOTO_BITMAP_PROJECTION, null, null, null);
try {
Bitmap thumbnail = null;
if (cursor.moveToFirst()) {
final byte[] thumbnailBytes = cursor.getBlob(0);
if (thumbnailBytes != null) {
thumbnail = BitmapFactory.decodeByteArray(thumbnailBytes,
0, thumbnailBytes.length);
}
}
return thumbnail;
} finally {
cursor.close();
}
}
}
and this is permission for read contacts:
<uses-permission android:name="android.permission.READ_CONTACTS"/>
