java - 找不到符号方法Android "findviewbyID"

Question

我是一名初学者，正在磨练我的应用程序开发技能。我目前正在做一个示例，其中列表由字符串数组填充。在最后的步骤中进行绑定(bind)，这是找不到方法“findviewbyid”的地方，并且在构建后显示为红色。有人可以指导我吗？

public MainActivityFragment() {
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {

    ArrayList<String> weather = new ArrayList<String>();
    weather.add("Today-Sunny-80/23");
    weather.add("Tomorrow-Sunny-83/23");
    weather.add("Fri-Sunny-80/23");
    weather.add("Sat-Rainy-80/23");
    weather.add("Sun-Sunny-80/23");
    weather.add("Mon-Foggy-80/23");

    ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(),  R.layout.list_item_forecast, R.id.list_item_forecast_textview, weather);

    ListView listView = (ListView) findViewByID(R.id.listView_Forecast);
    listView.setAdapter(adapter);

    return inflater.inflate(R.layout.fragment_main, container, false);

Answer 1

首先findViewByID应该是findViewById(小写d)

对于 fragment ，请在 onCreateView 中设置 View ，如下所示

// Call the layout inflater first
View view = inflater.inflate(R.layout.fragment_main, container, false);
// Initialize your views
ListView listView = (ListView) view.findViewById(R.id.listView_Forecast);
listView.setAdapter(adapter);

// Do the rest of your code
...
return view;
