我的对话框关闭
if (status.equals("true")) {
Toast.makeText(context, "" + msg, Toast.LENGTH_LONG).show();
notifyDataSetChanged();
dialog.dismiss();
}
我使用了notifyDataSetChanged（），但Fragment布局仍未刷新或未更新

答案 0 :(得分：0)
更新后，您应该更新orderlistArrayList
例如，如果您想更新在此编辑文本edtxt_order_referenece_id中输入的文本，则应从编辑文本中获取原始值，并应在项目位置orderlistArrayList.get(position).setPayRef(edtxt_order_referenece_id.getText().toString())对其进行更新< / p>
完成后，应致电notifyDataSetChanged();或notifyItemChanged(position);
