由EditText上的自定义ListAdapter失去焦点叫了两声 [英] Custom ListAdapter consisting of EditText lose focus called twice

问题描述

我想提出一个电子商务应用程序，其车列表中有一个自定义的ListView 这是由的EditText 的。项目的的EditText 重新presents的数量。我使用 OnFocusChangeListener 当客户完成改变，然后更新服务器上的车项目的数量来检测。一切正常，只是 onFocusChange 被调用两次即我越来越假的两倍。

I am making a E-commerce app whose cart list has a custom ListView which consist of EditText. The EditText represents the quantity of item. I am using OnFocusChangeListener to detect when a customer is done changing the quantity of the item then updating the cart on server. Everything is working fine, just the onFocusChange is being called twice i.e. I am getting false twice.

viewHolder.etProductQuantity.setOnFocusChangeListener( new View.OnFocusChangeListener() {

    @Override
    public void onFocusChange(View view, boolean hasFocus) {

        if(!hasFocus){

            // Updating the ProductList class's object to set the new quantity
            // Updating product quantity on server
            Log.d("Product Quantity", viewHolder.etProductQuantity.getText().toString() + b);
        }
    }
});

因此​​，正在执行的编码两次被创建问题

Thus, the coding is being executed twice which is creating problem.
