如何查詢聯繫一次

Question

編輯的所有細節：僅使用

1.NAME 
2.PHONE NUMBER 
3.EMAIL ADDRESS 
4.WEBSITE 
5.PHYSICAL ADDRESS 

我寧願這個使用預取的ContactID做...：什麼，我認爲重要的聯繫方式名單一個光標來獲取指定的所有數據。我最好想找到正確的查詢來做到這一點：

我想一次獲得聯繫人的所有重要細節，我使用下面的代碼要做到這一點：

 public void getAllDataByContactId(int contactId) 
{ 
    Log.d(TAG, "Seriously scared it might not work"); 
    String phoneNo="Phone disconnected"; 
    String email="Email could not be delivered"; 
    String website="Website 404"; 
    String address="Number 13,Dark Street,Area 51,Bermuda Trianlge"; 
    String name="Clint Eastwood"; 
    int hasPhoneNumber; 
    String selection=ContactsContract.Data.CONTACT_ID+"=?"; 
    String[] selectionArgs={String.valueOf(contactId)}; 
    Cursor c=context.getContentResolver().query(ContactsContract.Data.CONTENT_URI, null,selection, selectionArgs,ContactsContract.Data.TIMES_CONTACTED); 

    if(c!=null && c.getCount()>0) 
    { 

     while(c.moveToNext()) 
     { 

      phoneNo=c.getString(c.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER)); 
      Log.d(TAG, "Phone number: "+phoneNo); 
      email=c.getString(c.getColumnIndex(ContactsContract.CommonDataKinds.Email.ADDRESS)); 
      Log.d(TAG, "Email: "+email); 
      website=c.getString(c.getColumnIndex(ContactsContract.CommonDataKinds.Website.URL)); 
      Log.d(TAG, "Website :"+website); 
      address=c.getString(c.getColumnIndex(ContactsContract.CommonDataKinds.StructuredPostal.FORMATTED_ADDRESS)); 
      name=c.getString(c.getColumnIndex(ContactsContract.CommonDataKinds.StructuredName.DISPLAY_NAME)); 
      Log.d(TAG, "Name :"+name); 
     } 
    } 
} 

但是，雖然這不會引發錯誤，但它顯示了許多行，其中包含一個空字符串，其中包含實際值。如何編寫查詢以刪除噪音？

我已經試過這一點，這讓我所有的值：

   String selection=ContactsContract.Data.CONTACT_ID+"=? AND "+ContactsContract.Data.MIMETYPE+"=? OR "+ContactsContract.Data.MIMETYPE+"=? OR "+ContactsContract.Data.MIMETYPE+"=? OR "+ContactsContract.Data.MIMETYPE+"=? OR "+ContactsContract.Data.MIMETYPE+"=?"; 
    String[] selectionArgs={String.valueOf(contactId),ContactsContract.CommonDataKinds.StructuredName.CONTENT_ITEM_TYPE,ContactsContract.CommonDataKinds.Email.CONTENT_ITEM_TYPE,ContactsContract.CommonDataKinds.Phone.CONTENT_ITEM_TYPE,ContactsContract.CommonDataKinds.Website.CONTENT_ITEM_TYPE,ContactsContract.CommonDataKinds.StructuredPostal.CONTENT_ITEM_TYPE};

未必是最好的解決辦法。但這是我實現的方式。

ArrayList<String> fnameList = new ArrayList<>(); 
    ArrayList<String> lnameList = new ArrayList<>(); 
    ArrayList<String> mnumList = new ArrayList<>(); 
    ArrayList<String> hnumList = new ArrayList<>();
