java - Android 中带有复选框的 ListActivity

Question

我正在尝试使用 ListActivity 和 SimpleCursorAdapter 根据数据库查询来选中复选框。光标是问题和答案的列表。如果用户已经回答了问题，则应选中该复选框，但不会选中它们。代码如下所示:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
            setContentView(R.layout.questions);


    Cursor c;
    testDbAdapter db = new testDbAdapter(this);
    c = db.getQuestions(Long.toString(mRowId), Integer.toString(mSection));
            startManagingCursor(c);

            String[] from = new String[]{testDbAdapter.QUESTIONS_Q, testDbAdapter.QUESTIONS_A};
            int[] to = new int[]{R.id.question, R.id.answer};

            SimpleCursorAdapter results = new SimpleCursorAdapter(this, android.R.layout.simple_list_item_multiple_choice, c, from, to);


            setListAdapter(results);
  }

您可以扩展Adapter并重写bindView方法，或者调用setViewBinder。此处的类似问题回答了一些详细的解决方案:
