问题 I have a ListView that is filled by a CustomAdapter with a specific Layout. An ArrayList is passed as a parameter to this CustomAdapter, which contains the data for each ListView element. Each ListView element is composed by a TextView (where I display the data from the ArrayList) and a CheckBox at the right of it. The data in the ArrayList is correct.
