我想你想要一个ListView
左边有一个ImageView
,CheckBox
和每行TextView
。如果是这种情况,那么......不,你不能使用simple_list_item_multiple_choice
。您必须使用BaseAdapter才能实现此目的。
根据您的要求,您可以调整已使用的example并添加
ImageView
中每行的CheckBox
,TextView
和ListView
xml,并使用getView()
在适配器的LayoutInflater
中填充它们

请尝试以下代码段。
Activity_name.this.runOnUiThread(new Runnable() {
@Override
public void run() {
list = (ArrayList<Map<String, String>>) result;
this.adapter.setList(list);
this.adapter.notifyDataSetChanged();
}
});
