Android : Pick a number from calllog

I want user to select a number from calllog and that number get selected and come in the activity. So I created custom calllog list. I used this code but it is not showing the call log list in right order

first thing it is not recent

second not matching with the calllog list of phone

Can anyone tell what amendments i make in this code to make it right

The code I used is:

String[] callLogFields = { android.provider.CallLog.Calls._ID,
                android.provider.CallLog.Calls.NUMBER,
                android.provider.CallLog.Calls.CACHED_NAME /* im not using the name but you can*/};
        String viaOrder = android.provider.CallLog.Calls.DATE + " DESC";
        String WHERE = android.provider.CallLog.Calls.NUMBER + " >0"; /*filter out private/unknown numbers */

        final Cursor callLog_cursor = this.getContentResolver().query(
                android.provider.CallLog.Calls.CONTENT_URI, callLogFields,
                WHERE, null, viaOrder);

        AlertDialog.Builder myversionOfCallLog = new AlertDialog.Builder(this);

        android.content.DialogInterface.OnClickListener listener = new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialogInterface, int item) {
                callLog_cursor.moveToPosition(item);

                Log.v("number", callLog_cursor.getString(callLog_cursor
                        .getColumnIndex(android.provider.CallLog.Calls.NUMBER)));

                callLog_cursor.close();

            }
        };
        myversionOfCallLog.setCursor(callLog_cursor, listener,
                android.provider.CallLog.Calls.NUMBER);
        myversionOfCallLog.setTitle("Choose from Call Log");
        myversionOfCallLog.create().show();
