以编程方式更改联系人图片 [英] Change contact picture programmatically
问题描述
我有一张照片，存储在android手机中。我希望能够更改联系人的图片。
I have a picture, that is stored into the android phone. I want to be able to change the picture of a contact.
到目前为止，我要做的是启动联系人选择器，让用户选择一个联系人，然后我得到所选联系人的URI。从此联系人中，我可以获取关联的rawContact，并且可以使用此代码。
What I've done so far is launch the contact picker, have the user select a contact, and then I get the URI of the selected contact. From this contact, I can get the associated rawContact and I use this code.
Uri rawContactPhotoUri = Uri.withAppendedPath(
ContentUris.withAppendedId(RawContacts.CONTENT_URI, rawContactId),
RawContacts.DisplayPhoto.CONTENT_DIRECTORY);
try {
AssetFileDescriptor fd =
getContentResolver().openAssetFileDescriptor(rawContactPhotoUri, "rw");
OutputStream os = fd.createOutputStream();
os.write(photo);
os.close();
fd.close();
} catch (IOException e) {
// Handle error cases.
}
问题是，AssetFIleDescriptor始终为空（当我在其上调用长度时） ，我们总是得到-1）。
The problem is, the AssetFIleDescriptor is always empty (when I call length on it, we always get -1).
我并不需要整个解决方案，只需遵循一些线索即可帮助我实现这一目标。我似乎无法在StackOverflow上找到此问题，因此将不胜感激。
I'm not asking for the entire solution, just some leads to follow that can help me to get that working. I cannot seem to find this problem already on StackOverflow, so any help would be appreciated.

总是在我们提出问题时才找到解决方案。
我想与其他人共享它
It's always when we ask for question that we find the solution. I want to share it for other
所以我放弃了android链接并找到另一个链接：

So I gave up on android link and find another one : http://wptrafficanalyzer.in/blog/programatically-adding-contacts-with-photo-using-contacts-provider-in-android-example/
图片选择器返回所选联系人的Uri，因此这可以得到它的Contact._ID：
The picture picker return the Uri of the selected contact, so with this you can get the Contact._ID of it :
// This is onActivityResult
final Uri uri = data.getData();
final Cursor cursor1 = getContentResolver().query(uri, null, null, null, null);
cursor.moveToFirst();
final long contactId = cursor1.getLong(cursor1.getColumnIndex(Contacts._ID);
cursor1.close();
然后我必须获取RawContactId：
Then I had to get the RawContactId :
final Cursor cursor2 = getContentResolver().query(RawContacts.CONTENT_URI, null, RawContacts.Contact_ID + "=?", new String[] {String.valueOf(contactId)}, null);
cursor2.moveToFirst();
final long rawContactId = cursor2.getLong(cursor2.getColumnIndex(RawContacts._ID));
cursor2.close();
然后我必须获取RawContacts的Data._ID（与上面相同）。
Then I had to get the Data._ID of the RawContacts (same way as above).
然后我使用ContentProviderOperations：
Then I used the ContentProviderOperations :
final ArrayList<ContentProviderOperation> ops = new ArrayList<ContentProviderOperation>();
ops.add(ContentProviderOperation.newUpdate(Data.CONTENT_URI)
.withSelection(Data._ID, dataId),
.withValue(Data.MIMETYPE, ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE)
.withValue(ContactsContract.CommonDataKinds.Photo.PHOTO, byteArrayOfThePicture);
getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
这就像魅力一样。希望对您有帮助
And this is working like charm. Hope it helps
推荐答案
String contactId ="10001"; // change it as your IDs
if (mBitmap != null) {
// Picture
try {
ByteArrayOutputStream image = new ByteArrayOutputStream();
mBitmap.compress(Bitmap.CompressFormat.JPEG, 100, image);
Uri rawContactUri = null;
Cursor rawContactCursor = managedQuery(
ContactsContract.RawContacts.CONTENT_URI,
new String[]{ContactsContract.RawContacts._ID},
ContactsContract.RawContacts.CONTACT_ID + " = " + contactId,
null,
null);
if (!rawContactCursor.isAfterLast()) {
rawContactCursor.moveToFirst();
rawContactUri = ContactsContract.RawContacts.CONTENT_URI.buildUpon().appendPath("" + rawContactCursor.getLong(0)).build();
}
rawContactCursor.close();
ContentValues values = new ContentValues();
int photoRow = -1;
String where111 = ContactsContract.Data.RAW_CONTACT_ID + " == " +
ContentUris.parseId(rawContactUri) + " AND " + ContactsContract.Data.MIMETYPE + "=='" +
ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE + "'";
Cursor cursor = managedQuery(
ContactsContract.Data.CONTENT_URI,
null,
where111,
null,
null);
int idIdx = cursor.getColumnIndexOrThrow(ContactsContract.Data._ID);
if (cursor.moveToFirst()) {
photoRow = cursor.getInt(idIdx);
}
cursor.close();
values.put(ContactsContract.Data.RAW_CONTACT_ID,
ContentUris.parseId(rawContactUri));
values.put(ContactsContract.Data.IS_SUPER_PRIMARY, 1);
values.put(ContactsContract.CommonDataKinds.Photo.PHOTO, image.toByteArray());
values.put(ContactsContract.Data.MIMETYPE,
ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE);
if (photoRow >= 0) {
getContentResolver().update(
ContactsContract.Data.CONTENT_URI,
values,
ContactsContract.Data._ID + " = " + photoRow, null);
} else {
getContentResolver().insert(
ContactsContract.Data.CONTENT_URI,
values);
}
} catch (Exception e) {
Log.e("!_@@Image_Exception", e + "");
}
}
try {
getContentResolver().applyBatch(ContactsContract.AUTHORITY, ops);
} catch (Exception e) {
Log.e("@@@@@UPLOADERR", e + "");
}
