在android上更改联系人的图片？

Question

我正在尝试更改android上的联系人照片，我正在使用此处的代码： http://groups.google.com/group/android-developers/msg/7798b51e01c61c1e？

但它不起作用.. 我正在显示联系人列表，并且当用户单击其中一个联系人时，它的照片应该被更改为资源中的照片。 这里是我的全部代码：

public class ContactFacesActivity extends ListActivity { 

    ArrayList<Contact> Contacts; 
    ContentResolver cr; 

    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

     Contacts = new ArrayList<Contact>(); 



     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)); 
      if (Integer.parseInt(cur.getString(cur.getColumnIndex(ContactsContract.Contacts.HAS_PHONE_NUMBER))) > 0) { 
       Contacts.add(new Contact(name, id)); 
       } 
      } 

     setListAdapter(new ArrayAdapter<Contact>(ContactFacesActivity.this, android.R.layout.simple_list_item_1, Contacts)); 

     } 
    } 


    @Override 
    protected void onListItemClick(ListView l, View v, int position, long id) { 
     super.onListItemClick(l, v, position, id); 

     Bitmap temp = ((BitmapDrawable)getResources().getDrawable(R.drawable.house)).getBitmap(); 

     ByteArrayOutputStream bos = new ByteArrayOutputStream(); 
     temp.compress(CompressFormat.JPEG, 90 , bos); 
     byte[] bitmapdata = bos.toByteArray(); 

     setPhoto(Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_URI, Contacts.get(position).getID()), bitmapdata); 
    } 

    public void setPhoto(Uri personUri, byte[] photo) { 
       ContentValues values = new ContentValues(); 
       int photoRow = -1; 
       String where = ContactsContract.Data.RAW_CONTACT_ID + " == " + 
      ContentUris.parseId(personUri) + " AND " + Data.MIMETYPE + "=='" + 
      ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE + "'"; 
       Cursor cursor = getContentResolver().query 
      (ContactsContract.Data.CONTENT_URI, null, where, 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(personUri)); 
       values.put(ContactsContract.Data.IS_SUPER_PRIMARY, 1); 
       values.put(ContactsContract.CommonDataKinds.Photo.PHOTO, photo); 
       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); 
       } 
      } 

}

获取UR乌里联系人：

Uri iContactUri = null; 
    Cursor iContactCursor = managedQuery(
      RawContacts.CONTENT_URI, 
      new String[] {RawContacts._ID}, 
      RawContacts.CONTACT_ID + " = " + contactData.getLastPathSegment(), 
      null, 
      null); 
    if(!iContactCursor.isAfterLast()) { 
     iContactCursor.moveToFirst(); 
     iContactUri = RawContacts.CONTENT_URI.buildUpon().appendPath(""+iContactCursor.getLong(0)).build(); 
    } 
    ContactCursor.close(); 

然后为位图

Bitmap bit; // <-- put your bitmap here 
ByteArrayOutputStream streamy = new ByteArrayOutputStream(); 
bit.compress(CompressFormat.PNG, 0, streamy); 
byte[] photo = streamy.toByteArray(); 

照片

ContentValues values = new ContentValues(); 
int photoRow = -1; 
String where = ContactsContract.Data.RAW_CONTACT_ID + " == " + 
    ContentUris.parseId(rawContactUri) + " AND " + Data.MIMETYPE + "=='" + 
    ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE + "'"; 
Cursor cursor = managedQuery(
     ContactsContract.Data.CONTENT_URI, 
     null, 
     where, 
     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, photo); 
values.put(ContactsContract.Data.MIMETYPE, 
     ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE); 
if(photoRow >= 0){ 
    this.getContentResolver().update(
      ContactsContract.Data.CONTENT_URI, 
      values, 
      ContactsContract.Data._ID + " = " + photoRow, null); 
    } else { 
     this.getContentResolver().insert(
       ContactsContract.Data.CONTENT_URI, 
       values); 
    } 
}
