@android:ID/列表无法解析符号

Question

import android.app.ListFragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
/**
 * Created by name on 3/13/17.
 * Used for the specials tab to allow a list of days to choose what special one would like to view
 */
public class SpecialsScroll extends ListFragment implements AdapterView.OnItemClickListener{
    public SpecialsScroll(){
        //Empty Constructor
    }
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
        super.onCreate(savedInstanceState);
        return inflater.inflate(R.layout.fragment_specials_scroll, container, false);
    }
    @Override
    public void onActivityCreated(Bundle savedInstanceState){
        super.onActivityCreated(savedInstanceState);
        setListAdapter(ArrayAdapter.createFromResource(getActivity(), R.array.days, android.R.layout.simple_list_item_1)); //Loads array into the ListFragment
        getListView().setOnItemClickListener(this); //activates the listener for this Fragment class
    }
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id){ // For checking when a user taps on an option
        SpecialsPage specialsPage = new SpecialsPage();
        Bundle foodArgs = new Bundle();
        switch (position){ // checks what option is chosen and sends respective keys as parameters
            case 0:
                int[] keysMonday = {R.string.boom_boom_enchiladas_key, R.string.tacos_mexican_key};
                foodArgs.putIntArray("keys", keysMonday);
                break;
            case 1:
                int[] keysTuesday = {R.string.shrimp_avocado_tacos_key, R.string.green_chile_chicken_enchiladas_key};
                foodArgs.putIntArray("keys", keysTuesday);
                break;
        }
        specialsPage.setArguments(foodArgs);
        getActivity().getFragmentManager().beginTransaction().replace(R.id.container, specialsPage).addToBackStack(null).commit();
    }
}

import android.os.Bundle;
import android.support.annotation.NonNull;
import android.support.design.widget.BottomNavigationView;
import android.support.v7.app.AppCompatActivity;
import android.view.MenuItem;
public class MainActivity extends AppCompatActivity{
    private BottomNavigationView.OnNavigationItemSelectedListener mOnNavigationItemSelectedListener
            = new BottomNavigationView.OnNavigationItemSelectedListener() {
        @Override
        public boolean onNavigationItemSelected(@NonNull MenuItem item) {
            if(getFragmentManager().findFragmentByTag("CURRENT") == null){
                getFragmentManager().beginTransaction().add(R.id.container, new SpecialsScroll(), "CURRENT").commit();
            }
            switch (item.getItemId()) {
                case R.id.special:
                    getFragmentManager().beginTransaction().replace(R.id.container, new SpecialsScroll(), "CURRENT").commit();
                    return true;
                case R.id.locations:
                    getFragmentManager().beginTransaction().replace(R.id.container, new LocationsScroll(), "CURRENT").commit();
                    return true;
                case R.id.order:
                    return true;
            }
            return false;
        }
    };
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        BottomNavigationView navigation = (BottomNavigationView) findViewById(R.id.navigation);
        navigation.setOnNavigationItemSelectedListener(mOnNavigationItemSelectedListener);
        getFragmentManager().beginTransaction().add(R.id.container, new SpecialsScroll(), "CURRENT").commit();
    }
}

因此，我正在尝试创建一个listView，并且代码中的所有内容都可以使用，但是突然我无法获得XML来识别Android：ID/List属性，原因是某种原因，我不知道为什么。当我在应用程序中的ListView中单击一个项目时，它仍然可以做应该的事情，我真的想摆脱错误。

Answer 1

将您的id更改为：

 <ListView
        android:id="@+id/list"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
    </ListView>
