Recyclerview导致应用程序崩溃

Question

Android Dev Newbie在这里。 我在MainActivity中使用了recyclerview，该应用不断崩溃。

任何帮助将不胜感激！

编辑：对不起，我是新来的。 我已经附上了Logcat。 以及其他xml文件。 谢谢

这是我的代码：

list_layout.xml：

    <?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent">

    <android.support.v7.widget.CardView
        android:id="@+id/cardView"
        android:layout_width="match_parent"
        android:layout_height="140dp">

        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent">

            <TextView
                android:id="@+id/textView_Desc"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignBottom="@+id/imageView"
                android:layout_centerHorizontal="true"
                android:text="Description"
                android:textSize="25sp" />

            <ImageView
                android:id="@+id/imageView"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_margin="10dp"
                android:layout_marginTop="0dp"
                app:srcCompat="@drawable/ic_launcher_background" />

            <TextView
                android:id="@+id/textView_Name"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignTop="@+id/imageView"
                android:layout_centerHorizontal="true"
                android:text="Title"
                android:textAppearance="@style/TextAppearance.AppCompat"
                android:textColor="@color/Black"
                android:textSize="36sp" />
        </RelativeLayout>

    </android.support.v7.widget.CardView>
</LinearLayout>

activity_main.xml：

        android:layout_height="wrap_content"
        android:dividerHeight="5dp">

    </android.support.v7.app.AlertController.RecycleListView>


</RelativeLayout>



public class MainActivity extends AppCompatActivity {

RecyclerView recyclerView;
ProductAdapter productAdapter;
List<Product> productList;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);


    final LinearLayoutManager layoutManager = new LinearLayoutManager(this);
    layoutManager.setOrientation(LinearLayoutManager.VERTICAL);

    System.out.println("TAG : 1");

    productList = new ArrayList<>();

    productList.add(new Product(
       1,"Laptop","New Computer",R.drawable.ic_launcher_background
    ));

    productList.add(new Product(
            2, "Mobile Phone", "New Phone", R.drawable.ic_launcher_foreground

    recyclerView.setHasFixedSize(true);

    productAdapter = new ProductAdapter(this, productList);
    recyclerView.setLayoutManager(layoutManager);
    recyclerView.setAdapter(productAdapter);

}

}

ProductAdapter.java类：

public class ProductAdapter extends 

RecyclerView.Adapter<ProductAdapter.ProductViewHolder>{

private Context context;
private List<Product> productList;


public ProductAdapter(Context context, List<Product> productList) {
    this.context = context;
    this.productList = productList;
}

@Override

    LayoutInflater inflater = LayoutInflater.from(context);
    View view = inflater.inflate(R.layout.list_layout, null);


    ProductViewHolder productViewHolder = new ProductViewHolder(view);

    return new ProductViewHolder(view);
}

@Override
public void onBindViewHolder(ProductViewHolder holder, int position) {

    Product product = productList.get(position);
    holder.textView_Title.setText(product.getTitle());
    holder.textView_Desc.setText(product.getDesc());

    holder.imageView.setImageDrawable(context.getResources().getDrawable(product.getImage()));
}

@Override
public int getItemCount() {
    return productList.size();
}

class ProductViewHolder extends RecyclerView.ViewHolder {


    ImageView imageView;
    TextView textView_Title;
    TextView textView_Desc;


    public ProductViewHolder(View itemView) {
        super(itemView);

        imageView = itemView.findViewById(R.id.imageView);
        textView_Title = itemView.findViewById(R.id.textView_Name);
        textView_Desc = itemView.findViewById(R.id.textView_Desc);
    }
}

}

Answer 1

改变这个

<android.support.v7.app.AlertController.RecycleListView
        android:id="@+id/recyclerView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:dividerHeight="5dp">
    </android.support.v7.app.AlertController.RecycleListView>

至

<android.support.v7.widget.RecyclerView
            android:id="@+id/recyclerView"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
          />

AlertController.RecycleListView和RecyclerView都不同。
