public byte[] getPhoto(String
people_id) {
String photo_id = null;
String selection1 =
ContactsContract.Contacts._ID + " = " + people_id;
Cursor cur1 =
getContentResolver().query(
ContactsContract.Contacts.CONTENT_URI, null,
selection1, null,
null);
if (cur1.getCount() > 0)
{
cur1.moveToFirst();
photo_id =
cur1.getString(cur1
.getColumnIndex(ContactsContract.Contacts.PHOTO_ID));
//System.out.println("photo_id:"
+ photo_id);
}
String[] projection = new String[]
{
ContactsContract.Data.DATA15
};
String selection =
ContactsContract.Data._ID + " = " + photo_id;
Cursor cur =
getContentResolver().query(
ContactsContract.Data.CONTENT_URI, projection,
selection, null,
null);
cur.moveToFirst();
byte[] contactIcon =
cur.getBlob(0);
System.out.println("conTactIcon:" + contactIcon);
if
(contactIcon == null) {
return null;
} else {
return
contactIcon;
}
}
以下代码将字节数组转化成Bitmap对象，然后再ImageView中显示出来
private
ImageView image;
byte[] photo = getPhoto(contactId);
Bitmap map =
BitmapFactory.decodeByteArray(photo,
0,
photo.length);
image.setImageBitmap(map);
