解决方法
这个怎么样:
List<Employee> results = (List<Employee>) query.execute(); // Use the first 20 results... Cursor cursor = JPACursorHelper.getCursor(results); String cursorString = cursor.toWebSafeString(); // Store the cursorString... // ... // Query query = the same query that produced the cursor // String cursorString = the string from storage Cursor cursor = Cursor.fromWebSafeString(cursorString); query.setHint(JPACursorHelper.CURSOR_HINT,cursor); query.setRange(0,20); List<Employee> results = (List<Employee>) query.execute(); // Use the next 20 results...
