Android Eclipse：GridView項目不可點擊？

Question

我實現了一個gridview，在其中填充一個「產品」數組以及另一個「產品圖像」數組以填充Sqlite數據庫中的產品的網格視圖列表。但是，當我設置OnItemClickListener時，在我的設備上運行應用程序時，gridview項目不可點擊。它只是能夠向下滾動產品和圖像，但不能點擊。

該應用程序運行良好，圖像與產品詳細信息一起顯示，但每個網格項目都不可點擊。爲什麼會發生這種情況？

這裏是我的代碼：

MainActivity類別

gridView = (GridView)findViewById(R.id.grid); 
      ProductGridInflator bA = new ProductGridInflator(this, R.layout.home ,dbProducts, dbImages); 
      gridView.setAdapter(bA); 

      gridView.setOnItemClickListener(new OnItemClickListener() { 


       @Override 
       public void onItemClick(AdapterView<?> parent, View view, 
         int position, long id) { 

        Product currentProduct = new Product(); 

        String product_name=null; 

        for(int i=0;i<dbProducts.size();i++) 
        { 
         product_name = dbProducts.get(i).NAME; 
        } 

      //Sharing product details with all windows 
        SharedPreferences pref = getApplicationContext().getSharedPreferences("AppProduct", 0); // 0 - for private mode 
        Editor editor = pref.edit(); 
        editor.putString("pname", product_name); 
        editor.commit(); 

        Intent inn1=getIntent(); 
        inn1=new Intent(HomeActivity.this, ProductSingle_Activity.class); 
        startActivity(inn1); 

       } 
      });

嘗試將內容添加到另一個佈局，然後將該佈局充氣到網格視圖。

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

        View grid = convertView; 
        if (convertView == null) { 

        grid = inflater.inflate(R.layout.gridview_layout, parent, false); 
        } else { 
        grid = (View) convertView; 
      } 

     final Button bt = (Button) grid.findViewById(R.id.ready); 
     final TextView tno=(TextView)grid.findViewById(R.id.txt); 
     final TextView name=(TextView)grid.findViewById(R.id.txt3); 
     final TextView qty=(TextView)grid.findViewById(R.id.txt4); 
     final TextView instr=(TextView)grid.findViewById(R.id.txt5); 

     dish = data.get(position); 

     tno.setText(dish.get(KEY_TNO)); 
     name.setText("NAME: "+dish.get(KEY_NAME)); 
     qty.setText("QTY:"+dish.get(KEY_QUANTITY)); 
     instr.setText("INSTRN: "+dish.get(KEY_INSTRUCTION)); 


     bt.setOnClickListener(new View.OnClickListener() { 

      @Override 
      public void onClick(View v) { 
       // TODO Auto-generated method stub 

       String tn = tno.getText().toString(); 
       System.out.println("TABLE NO:"+tn); 
       Toast.makeText(getApplicationContext(), "Successssss"+tn, Toast.LENGTH_SHORT).show(); 


      } 
     }); 

     return grid; 
    }

GridView onItemClick在網格項內的任何視圖都是可點擊時未觸發。我看到您的網格項目佈局包含默認可點擊的Horizo​​ntalScrollView（這非常合理，當點擊事件不由scrollview處理時，如何與滾動視圖進行交互）。

如果你想使用這樣的佈局，你必須處理網格項目級別的所有點擊事件，而不是網格級別。
