在Android 2.3和Android 4.0上聯繫人照片uri

我的代碼有問題。我需要獲取聯繫人照片URI，並在我的ImageView中顯示圖片。我寫了這段代碼，它在Android 2.3中正常工作。在Android 2.3和Android 4.0上聯繫人照片uri

Uri myUri = getPhotoUriById(this, contactId); 
(ImageView)myImageView.setImageUri(myUri); 

public static Uri getPhotoUriById(Context context, Long id) { 
    if(id == null || context == null) return null; 

    Uri photo = Uri.parse("android.resource://"+ context.getPackageName() +"/" + R.drawable.no_photo); 

    Cursor cursor = context.getContentResolver().query(Contacts.CONTENT_URI, 
      new String[]{ Contacts.PHOTO_ID }, 
      Contacts._ID + " = " + id + " AND " + Contacts.PHOTO_ID + " != 0", 
      null, 
      null); 
    if(cursor != null) { 
     if(cursor.moveToFirst()) { 
      photo = ContentUris.withAppendedId(Contacts.CONTENT_URI, id); 
      photo = Uri.withAppendedPath(photo, Contacts.Photo.CONTENT_DIRECTORY); 
     } 
     cursor.close(); 
    } 
    return photo; 
}

但是當我在Android 4.0（ICS）測試它。我遇到了很多問題。

你找到答案它將拋出一個異常？如果你發現它PLZ分享它，因爲IAM面臨同樣的問題 – AnasBakez

幾天後，我寫了正確的代碼。這適用於所有Android版本。有我的解決方案

public static Uri getPhotoUriById(Context context, Long id) { 
    if(id == null || context == null) return null; 

    Uri photo = Uri.parse("android.resource://"+ context.getPackageName() +"/" + R.drawable.no_photo); 

    try { 
     Cursor cursor = context.getContentResolver().query(Contacts.CONTENT_URI, 
       new String[]{ Contacts.PHOTO_ID, "photo_uri" }, 
       Contacts._ID + " = " + id + " AND " + Contacts.PHOTO_ID + " != 0", 
       null, 
       null); 
     if(cursor == null) 
      return photo; 
     if(!cursor.moveToFirst()) { 
      cursor.close(); 
      return photo; 
     } 
     String sUri; 
     if((sUri = cursor.getString(cursor.getColumnIndex("photo_uri"))) != null) { 
      cursor.close();               // content://com.android.contacts/display_photo/1 
      return Uri.parse(sUri); 
     } 
     cursor.close(); 
     return photo; 
    } catch(Exception e) { 
     Cursor cursor = context.getContentResolver().query(Contacts.CONTENT_URI, 
       new String[]{ Contacts.PHOTO_ID }, 
       Contacts._ID + " = " + id + " AND " + Contacts.PHOTO_ID + " != 0", 
       null, 
       null); 
     if(cursor == null) 
      return photo; 
     if(!cursor.moveToFirst()) { 
      cursor.close(); 
      return photo; 
     } 
     cursor.close(); 
     photo = ContentUris.withAppendedId(Contacts.CONTENT_URI, id); 
     photo = Uri.withAppendedPath(photo, Contacts.Photo.CONTENT_DIRECTORY); 
     return photo; 
    } 
}

「photo_uri」是一個常數Contacts.PHOTO_URI，這是從API級別11

嗨，我有這個代碼時，我使用的問題，它給了我在TRY正文的ICS Android版本的不良URI。任何解決方案或我錯過了什麼？ –

正如你所說的「photo_uri」是從API LEVEL 11中添加的，那麼它將如何在Android應用程序中使用支持2.2？我得到了一個像** content：//com.android.contacts/contacts/271/photo**這樣的同步聯繫人圖片的不同URI，因此它不會提供任何圖片作爲回報，並且會按照上面的說明提供異常。 –

@RushabhPatel catch（）塊在API 10及更低版本的設備上工作，因爲getContentResolver（）。query（）會給出異常，在這種情況下，該函數返回即** content：//com.android.contacts/contacts/251 /照片**。 – artemkaxboy

原來的答案效果很好，但我認爲這可以提高大量補充。我沒有看到try/catch中的需求，當你可以使用底部的代碼時，它沒有折舊的方法。這個支持API的級別爲10 - 19（可能低於此值，但我從未檢查過）。這是我得到它下降到

Uri photo = ContentUris.withAppendedId(ContactsContract.Contacts.CONTENT_URI, id); 
    photo = Uri.withAppendedPath(photo, ContactsContract.Contacts.Photo.CONTENT_DIRECTORY); 
    Bitmap bitmap = MediaStore.Images.Media.getBitmap(contentResolver, photo);

如果沒有照片
