android - setOnItemClickListener 事件不起作用

Question

我有 listView 和 SimpleAdapter，它们设置了我的 listView。但是没有引发 setOnItemClickListener 事件。

@Override
protected void onCreate(Bundle savedInstanceState) 
{
  super.onCreate(savedInstanceState);
  mContext = this;
  setContentView(R.layout.add_item_from_subcateg);
  subcategName = getIntent().getExtras().getString("subcategName");
  mySQLWorker = new MySQLWorker(this);
  mySQLWorker.open();
  list_view_products = (ListView) findViewById(android.R.id.list);
  finishLoading(null);
}

public void finishLoading(ArrayList<HashMap<String, Object>> result)
{

  HashMap<String, Object> hashmap;
  List<ProductInfo> products = mySQLWorker.GetProductsByCategory(subcategName);


  for (ProductInfo product : products) 
  {
     hashmap = new HashMap<String, Object>();
     hashmap.put("ItemID", product.getID());
     hashmap.put("image_product", product.getImagePath());
     hashmap.put("product_name", product.getName());
     hashmap.put("lbl_protein_count", product.getProtein());
     hashmap.put("lbl_fat_count", product.getFat());
     hashmap.put("lbl_carbohydrates_count", product.getCarbohydrates());
     list_products.add(hashmap);
  }


  adapterProductsList = new SimpleAdapter(mContext, list_products,
  R.layout.product_template, new String[] { "image_product",
  "product_name", "lbl_protein_count",
  "lbl_fat_count", "lbl_carbohydrates_count" }, new int[] {  

  R.id.image_product,R.id.product_name, R.id.lbl_protein_count,
  R.id.lbl_fat_count,R.id.lbl_carbohydrates_count });
        list_view_products.setAdapter(adapterProductsList);
        adapterProductsList.notifyDataSetChanged();         
        progress_dialog.dismiss();

        list_view_products.setOnItemClickListener(new
  AdapterView.OnItemClickListener()
        {
        @Override
            public void onItemClick(AdapterView<?> arg0, View arg1, int position, long
  arg3)
            {
                Toast.makeText(mContext, "312", Toast.LENGTH_SHORT).show();
            }
        });
    }

和 XML:

<?xml version="1.0" encoding="UTF-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@android:color/background_dark" >

<ListView
    android:id="@android:id/list"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:focusable="false"
    android:focusableInTouchMode="false">
</ListView>

</RelativeLayout>

谢谢你的提前!

更新:

ListView 布局:

Answer 1

我认为您的 ImageButton 正在窃取 onItemClickLister 事件。将此属性添加到您的布局

 android:descendantFocusability="blocksDescendants"

并且还删除了 android:clickable="true"东西。 所以应该是这样的

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/lv_item"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:descendantFocusability="blocksDescendants"
android:orientation="horizontal" >

<ImageView
    android:id="@+id/image_product"
    android:layout_width="120dp"
    android:layout_height="80dp"
    android:layout_margin="4dp" />
......

谢谢
