我正在尝试创建一个自定义列表，每当我输入EditText框时，它应该反映在该行的总数中。下面是我的代码，在我的代码中，即使我键入{{1盒子。请帮我修复bug。

像这样添加其他块
if (v == null) {
v = mInflater.inflate(R.layout.material_list, parent,false);
holder = new ViewHolder();
holder.txtName=(TextView)v.findViewById(R.id.txtName);
holder.txtRate=(TextView)v.findViewById(R.id.txtRate);
holder.txtTotAmt=(TextView)v.findViewById(R.id.txtMainTotal);
holder.edtQty=(EditText)v.findViewById(R.id.edtQty);
holder.txtRowTotal=(TextView)v.findViewById(R.id.txtFinal);
holder.txtDis=(TextView)v.findViewById(R.id.txtDiscount);
v.setTag(holder);
}else{
holder = (ViewHolder)v.getTag();
}
