獲取聯繫人

Question

的Android 2.3.3

我發現下面的代碼在其中一個例子的照片...

String image = cur.getString(cur.getColumnIndex(ContactsContract.CommonDataKinds.Phone.PHOTO_URI)); 

       if (image != null) { 
        contactViewHolder.imgContact.setImageURI(Uri.parse(image)); 
       } else { 
        contactViewHolder.imgContact 
          .setImageResource(R.drawable.addcontactsmall2); 
       } 

但是，當我嘗試運行應用程序，它給了我IllegalStateException。然而，我沒有在其他地方找到這個URI。這是獲取聯繫人照片的正確方法嗎？

這是我所看到的，當我把我的光標移到PHOTO_URI :::

字符串android.provider.ContactsContract.ContactsColumns.PHOTO_URI = 「photo_uri」

public static final String PHOTO_URI 
    Added in API level 11 
    A URI that can be used to retrieve the contact's full-size photo. 
If PHOTO_FILE_ID is not null, this will be populated with a URI based off CONTENT_URI. 
Otherwise, this will be populated with the same value as PHOTO_THUMBNAIL_URI. 
A photo can be referred to either by a URI (this field) or by ID (see PHOTO_ID). 
If either PHOTO_FILE_ID or PHOTO_ID is not null, PHOTO_URI and PHOTO_THUMBNAIL_URI shall not be null (but not necessarily vice versa). 
Thus using PHOTO_URI is a more robust method of retrieving contact photos. 

    Type: TEXT 


    Constant Value: "photo_uri"

希望這將幫助你（接觸通過的getId（））鑑定：

/** 
* @return the photo URI 
*/ 
public Uri getPhotoUri() { 
    try { 
     Cursor cur = this.ctx.getContentResolver().query(
       ContactsContract.Data.CONTENT_URI, 
       null, 
       ContactsContract.Data.CONTACT_ID + "=" + this.getId() + " AND " 
         + ContactsContract.Data.MIMETYPE + "='" 
         + ContactsContract.CommonDataKinds.Photo.CONTENT_ITEM_TYPE + "'", null, 
       null); 
     if (cur != null) { 
      if (!cur.moveToFirst()) { 
       return null; // no photo 
      } 
     } else { 
      return null; // error in cursor process 
     } 
    } catch (Exception e) { 
     e.printStackTrace(); 
     return null; 
    } 
    Uri person = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, Long 
      .parseLong(getId())); 
    return Uri.withAppendedPath(person, ContactsContract.Contacts.Photo.CONTENT_DIRECTORY); 
} 

用法爲：

Uri u = objItem.getPhotoUri(); 
if (u != null) { 
     mPhotoView.setImageURI(u); 
} else { 
     mPhotoView.setImageResource(R.drawable.ic_contact_picture_2); 
}
