在列表视图上删除按钮事件不起作用

Question

我有一个列表视图的活动，列表视图包含一个imageview作为每行中的删除按钮。我已经将onclicklistener添加到imageview，但它不起作用。

这是其中包含的ListView主要布局：

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

<ListView 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:id="@+id/cart_list_view" 
    android:listSelector="@android:color/transparent" 
    android:cacheColorHint="@android:color/transparent"> 
</ListView> 

这是由该ArrayList适配器处理的布局：

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
xmlns:card_view="http://schemas.android.com/apk/res-auto" 
android:id="@+id/activity_cart" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:paddingBottom="@dimen/activity_vertical_margin" 
android:paddingLeft="@dimen/activity_horizontal_margin" 
android:paddingRight="@dimen/activity_horizontal_margin" 
android:paddingTop="@dimen/activity_vertical_margin" 
tools:context="com.example.badr.eco.CartActivity"> 

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

    <ImageView 
     android:contentDescription="row" 
     android:id="@+id/ImgProduct" 
     android:layout_width="150px" 
     android:layout_height="150px" 
     android:layout_margin="6dp"/> 

    <TextView 
     android:id="@+id/TitleProduct" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_marginLeft="180px" 
     android:textSize="20sp" 
     android:layout_marginTop="10dp" 
     /> 
    <TextView 
     android:id="@+id/PriceProduct" 
     android:layout_below="@id/TitleProduct" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_marginLeft="180px" 
     android:layout_marginTop="10dp" 
     android:textSize="20sp" 
     /> 

    <ImageView 
     android:id="@+id/delete_item_from_cart" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:src="@drawable/ic_delete_black_24dp" 
     android:layout_alignTop="@+id/PriceProduct" 
     android:layout_alignParentRight="true" 
     android:layout_alignParentEnd="true" /> 
</RelativeLayout> 

代码我的ArrayList适配器：

public class CartListAdapter extends ArrayAdapter<String> { 

    private ImageView img_prdtct; 
    private TextView title_prdct; 
    private TextView price_prdct; 
    private DBHelper Mydb; 
    private ImageView Img_delete; 

    private Context context; 
    private ArrayList<String> My_prdcts_List; 

    public CartListAdapter(Context context, int resource, ArrayList<String> objects) { 
     super(context, resource, objects); 
     this.context = context; 
     My_prdcts_List = objects; 
    } 

    @NonNull 
    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 

     LayoutInflater inflater = (LayoutInflater) 
       getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

     View rowView = inflater.inflate(R.layout.activity_cart, parent, false); 

     String obj = My_prdcts_List.get(position); 
     String [] items = obj.split("/"); 

     img_prdtct = (ImageView)rowView.findViewById(R.id.ImgProduct); 
     title_prdct = (TextView)rowView.findViewById(R.id.TitleProduct); 
     price_prdct = (TextView)rowView.findViewById(R.id.PriceProduct); 
     Img_delete = (ImageView) rowView.findViewById(R.id.delete_item_from_cart); 

     title_prdct.setText(items[0]); 
     price_prdct.setText(items[1] + "DH"); 
     img_prdtct.setImageResource(Integer.parseInt(items[2])); 

     //Les evenements 
     img_prdtct.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       Toast.makeText(context, "Clicked",Toast.LENGTH_SHORT).show(); 
       //Log.d("Clicked", "deleteButton"); 
      } 
     }); 
     return rowView; 
    } 
} 

Acivity代码：

public class CartActivity extends AppCompatActivity { 

    private DBHelper Mydb; 
    private ArrayList<String> Array_List; 

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

     Array_List = new ArrayList<>(); 
     Mydb = new DBHelper(this); 
     Array_List = Mydb.getAllRows("cart"); 

     CartListAdapter adapter = new CartListAdapter(this,0,Array_List); 

     ListView list = (ListView)findViewById(R.id.cart_list_view); 
     list.setAdapter(adapter); 
    } 
} 

最后这样的结果，但该事件的点击不起作用。 ListView

我发现这个错误，我刚更换过 img_prdtct.setOnClickListener到Img_delete.setOnClickListener
