使用联系人ID获取RawContact id

我已经构建了以下方法，使用从Contacts表中获取的id从RawContacts表中获取id。此方法无法引发异常。使用联系人ID获取RawContact id

 public int getRawContactId(int contactId) 
{ 
    String[] projection=new String[]{ContactsContract.RawContacts._ID}; 
    String selection=ContactsContract.RawContacts.CONTACT_ID+"=?"; 
    String[] selectionArgs=new String[]{String.valueOf(contactId)}; 
    Cursor c=context.getContentResolver().query(ContactsContract.RawContacts.CONTENT_URI,projection,selection,selectionArgs , null); 
    int rawContactId=c.getInt(c.getColumnIndex(ContactsContract.RawContacts._ID)); 
    Log.d(TAG,"Contact Id: "+contactId+" Raw Contact Id: "+rawContactId); 
    return rawContactId; 
}

相应的logcat看起来是这样的：

      java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, 
      request=1, result=-1, data=Intent {

您需要在第一个位置移动光标。默认情况下，游标设置为-1索引，因此将其移动到第0位需要使用moveToFirst()。

所以，你可以修改代码就像

Cursor c = context.getContentResolver().query(ContactsContract.RawContacts.CONTENT_URI,projection,selection,selectionArgs , null);  
if (c.moveToFirst()) {  
    int rawContactId=c.getInt(c.getColumnIndex(ContactsContract.RawContacts._ID)); 
}

明白了......哎呀......这样一个业余的错误。 – vamsiampolu

public static String getRawContactId(String contactId) 
{ 
    String res = ""; 
    Uri uri = ContactsContract.RawContacts.CONTENT_URI; 
    String[] projection = new String[]{ContactsContract.RawContacts._ID}; 
    String selection = ContactsContract.RawContacts.CONTACT_ID + " = ?"; 
    String[] selectionArgs = new String[]{ contactId }; 
    Cursor c = ContentManager.getContentResolver().query(uri, projection, selection, selectionArgs, null); 

    if(c != null && c.moveToFirst()) 
    { 
     res = c.getString(c.getColumnIndex(ContactsContract.RawContacts._ID)); 
     c.close(); 
    } 

    return res; 
}
