Answer 3

我猜你想要一个ListView在ImageView左角CheckBox有一个TextView，每行都有一个。如果是这种情况，那么...不，您不能使用simple_list_item_multiple_choice. 您将不得不使用 BaseAdapter 来实现这一点。根据您的要求，您可以调整您使用 的示例ImageView，并将 aCheckBox和 a添加TextView到您的 xml 中的每一行，ListView并使用 a 将它们填充到getView()适配器的LayoutInflater

试试下面的代码片段。

Activity_name.this.runOnUiThread(new Runnable() {

  @Override
  public void run() {
  list = (ArrayList<Map<String, String>>) result;
  this.adapter.setList(list);
  this.adapter.notifyDataSetChanged();
}
});
