Android - How do I load a contact Photo?
- by PaulH
I'm having trouble loading a photo for a contact in Android. I've googled for an answer, but so far have come up empty. Does anyone have an example of querying for a Contact, then loading the Photo?
So, given a contactUri which comes from an Activity result called using
startActivityForResult(new Intent(Intent.ACTION_PICK,ContactsContract.CommonDataKinds.Phone.CONTENT_URI),PICK_CONTACT_REQUEST)
is:
content://com.android.contacts/data/1557
The loadContact(..) works fine. However when I call the getPhoto(...) method, I get a null value for the photo InputStream. It is also confusing because the URI values are different. The contactPhotoUri evaluates to:
content://com.android.contacts/contacts/1557
See the comments inline in the code below.
class ContactAccessor {
/**
* Retrieves the contact information.
*/
public ContactInfo loadContact(ContentResolver contentResolver, Uri contactUri) {
//contactUri --> content://com.android.contacts/data/1557
ContactInfo contactInfo = new ContactInfo();
// Load the display name for the specified person
Cursor cursor = contentResolver.query(contactUri,
new String[]{Contacts._ID,
Contacts.DISPLAY_NAME,
Phone.NUMBER,
Contacts.PHOTO_ID}, null, null, null);
try {
if (cursor.moveToFirst()) {
contactInfo.setId(cursor.getLong(0));
contactInfo.setDisplayName(cursor.getString(1));
contactInfo.setPhoneNumber(cursor.getString(2));
}
} finally {
cursor.close();
}
return contactInfo; // <-- returns info for contact
}
public Bitmap getPhoto(ContentResolver contentResolver, Long contactId) {
Uri contactPhotoUri = ContentUris.withAppendedId(Contacts.CONTENT_URI, contactId);
// contactPhotoUri --> content://com.android.contacts/contacts/1557
InputStream photoDataStream = Contacts.openContactPhotoInputStream(contentResolver,contactPhotoUri); // <-- always null
Bitmap photo = BitmapFactory.decodeStream(photoDataStream);
return photo;
}
public class ContactInfo {
private long id;
private String displayName;
private String phoneNumber;
private Uri photoUri;
public void setDisplayName(String displayName) {
this.displayName = displayName;
}
public String getDisplayName() {
return displayName;
}
public void setPhoneNumber(String phoneNumber) {
this.phoneNumber = phoneNumber;
}
public String getPhoneNumber() {
return phoneNumber;
}
public Uri getPhotoUri() {
return this.photoUri;
}
public void setPhotoUri(Uri photoUri) {
this.photoUri = photoUri;
}
public long getId() {
return this.id;
}
public void setId(long id) {
this.id = id;
}
}
}
Clearly, I'm doing something wrong here, but I can't seem to figure out what the problem is. Thanks.
