我目前正在尝试从SQL查询中填充片段内的ListView。 ListView有一个名为list_order_layout_order_progress的自定义列表视图。一旦我到达特定片段，它就会崩溃。
任何帮助将不胜感激。提前谢谢！
On create View我在哪里声明了listview
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.tabe_fragment_order_progress, container, false);
OrderNumber = getArguments().getInt("OrderNoFinal");
ProductID = getArguments().getInt("ProductID");
ProductionID = getArguments().getInt("ProductionID");
lblOrderNo = (TextView) rootView.findViewById(R.id.txtProgOrderNo);
lblProduct = (TextView) rootView.findViewById(R.id.txtProgProduct);
listView = (ListView) rootView.findViewById(R.id.listView);
connectionClass = new ConnectionClass();
GetProductName();
PopulateOrderProgressList();
return rootView;
}
我设置数组适配器的代码
public void PopulateOrderProgressList(){
Connection con = connectionClass.CONN();
try {
String sql = "exec sp_Get_Production_Tasks\n@Production_ID = " + ProductionID + ",@Product_ID = " + ProductID;
final ArrayList list = new ArrayList();
PreparedStatement statement = con.prepareStatement(sql);
ResultSet rs = statement.executeQuery();
while (rs.next()) {
list.add(rs.getString("Task_Name"));
}
listView.setAdapter(new ArrayAdapter<String>(getActivity().getApplicationContext(),R.layout.list_layout_orderprogress , list));
}
catch(SQLException e){
Toast.makeText(getActivity(), e.getMessage(), Toast.LENGTH_LONG).show();
}
}
包含作为片段的ListView的布局：

答案 0 :(得分：0)
ArrayAdapter只知道如何处理TextViews列表。您想要使用自定义视图列表，因此您必须创建自定义ArrayAdapter。这可以通过创建继承ArrayAdapter的子类来完成。
来自ArrayAdapter的Android documentation： “默认情况下，此类要求提供的资源ID引用单个TextView。”
以下是我第一次使用自定义ArrayAdapter时的教程：http://www.ezzylearning.com/tutorial/customizing-android-listview-items-with-custom-arrayadapter
