我有一个自定义的Dialog Fragment，我需要在其中显示一个Alert dialog。
是否可以不关闭Dialog fragment而做？当我使用为context提供的Dialog fragment进行操作时，它只是关闭Dialog fragment并打开Alert dialog。
case R.id.deleteButton:
new AlertDialog.Builder(context)
.setTitle(context.getResources().getString(R.string.discard_changes))
.setIcon(android.R.drawable.ic_dialog_alert)
.setPositiveButton(android.R.string.yes, (dialog, whichButton) -> {
onItemClickListener.onItemClick(Device, DELETE_DOC);
dismiss();
})
.setNegativeButton(android.R.string.no, null).show();
break;

根据要求，整个对话框代码：
