Question

我正在尝试用汽车创建简单的Android跑步游戏，汽车列表将处于活动中，其中具有背景和listview。带有图标和字符串的列表视图（车辆及其名称的图标）当我尝试实现listview时，出现以下异常：

android.content.res.Resources$NotFoundException: Resource ID #0x102000a type #0x12 is not valid

我一直在寻找关于stackoverflow的答案，但没有找到答案。试图更改资源，请删除setContentView（）。

car_list.xml：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:padding="5dp" >
    <ImageView
        android:id="@+id/logo"
        android:layout_width="100px"
        android:layout_height="100px"
        android:layout_marginLeft="5px"
        android:layout_marginRight="20px"
        android:layout_marginTop="5px"
        android:src="@drawable/bike" >
    </ImageView>
    <TextView
        android:layout_marginStart="100dp"
        android:id="@+id/label"
        android:text="@+id/label"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:padding="10dp"
        android:textSize="20sp"
        android:textAlignment="center">
    </TextView>
</LinearLayout>

activity_cars.xml：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/bgpick"
    >
    <TextView
        android:layout_marginTop="20dp"
        android:layout_gravity="center"
        android:gravity="center"
        android:layout_width="350dp"
        android:layout_height="wrap_content"
        android:text="Pick a vehicle"
        android:textStyle="bold"
        android:textColor="@color/colorWhite"
        android:textSize="40dp"
        android:background="@drawable/btns"
        android:layout_marginBottom="40dp"
        />
    <ListView
        android:layout_gravity="center"
        android:id="@android:id/list"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        />
</LinearLayout>

ListCarsActivity.java：

public class ListCarsActivity extends Activity {

    private CarsArrayAdapter carsArrayAdapter;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_cars);
        final ListView listView=findViewById(android.R.id.list);
        String[] CARS = new String[] { "Sport","Tank","Space Ship","Mercedes" };
        final ArrayList<String> list=new ArrayList<String>();
        for(int i=0;i<CARS.length;++i)
            list.add(CARS[i]);

        final StableArrayAdapter adapter = new StableArrayAdapter (this,android.R.id.list,list);
        listView.setAdapter(adapter);
    }
    private class StableArrayAdapter extends ArrayAdapter<String> {
        HashMap<String, Integer> mIdMap = new HashMap<String, Integer>();

        public StableArrayAdapter(Context context, int textViewResourceId,
                                  List<String> objects) {
            super(context, textViewResourceId, objects);
            for (int i = 0; i < objects.size(); ++i) {
                mIdMap.put(objects.get(i), i);
            }
        }

        @Override
        public long getItemId(int position) {
            String item = getItem(position);
            return mIdMap.get(item);
        }
        @Override
        public boolean hasStableIds() {
            return true;
        }
    }
}

我不知道为什么要收到异常，我三重确保所有资源都位于同一名称下。谢谢您的协助。

Answer 1

wsUrl

到

static async getInitialProps({ req }) {
    if (req) {

     // WRONG: IN THIS CASE `wsUrl` value is undefiend 
      const { wsUrl } = req;
      return { collections: req.user.collections, email: req.user.id, wsUrl };
    }
    // IN THIS CASE I AM GETTING THE `wsUrl` value
    const { wsUrl } = await getWebSocketUrl();

    return {
      wsUrl
    };
  }

以及当我为视图创建ID

setContentView(R.layout.activity_cars);

更改

这也是

setContentView(R.layout.car_activity);
