java Android Studio无法解析列表适配器中的方法

Question

我创建了一个自定义列表适配器，它从基本适配器扩展而来，因为我需要在列表中输入两个数组。代码如下：

public class OweListAdaptor extends BaseAdapter {
String[] descriptionArray, valueArray;
Context context;

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    LayoutInflater inflater = LayoutInflater.from(context);
    View oweRow = inflater.inflate(R.layout.oweitem, parent, false);

    TextView description = (TextView) oweRow.findViewById(R.id.descText);
    TextView value = (TextView) oweRow.findViewById(R.id.valText);
    description.setText(descriptionArray[position]);
    value.setText(valueArray[position]);

    return oweRow;
}

public OweListAdaptor(String[] description, String[] value) {
    this.descriptionArray = description;
    this.valueArray = value;
}

public void updateValues(String[] newList){
    for (int i=0; i< newList.length; i++){
        valueArray[i] = newList[i];
    }
    this.notifyDataSetChanged();
}

public void updateDescriptions(String[] newList){
    for (int i=0; i< newList.length; i++){
        descriptionArray[i] = newList[i];
    }
    this.notifyDataSetChanged();
}

无法从MainActivity调用最后两个方法UpdateValue和updateDescriptions。当我试图给他们打电话时，安卓工作室说了

cannot resolve method 'updateValues(java.lang.String[])'

我只是在MainActivity中使用了以下内容

public class MainActivity extends AppCompatActivity {
String[] descriptionList, valueList;
OweDBManager DB;
ListAdapter oweAdapter;

public void updateLists(){
    descriptionList = DB.DBtoArray("desc");
    valueList = DB.DBtoArray("value");
    oweAdapter.updateValues(valueList);
}

DB管理器和列表适配器在onStart中初始化。为什么我会犯这个错误

Answer 1

使用OwellistAdapter代替ListAdapter，就像使用自定义适配器一样

Answer 2

将main活动从ListAdapter oweAdapter更改为OweListAdaptor oweAdapter，它将起作用
