列表视图与阵列适配器自定义视图布局。需要资源ID

标签： android android-layout listview android-fragments android-arrayadapter

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();
    }
}

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
