java希望保留我在编辑访问页面时选择的数据
我有屏幕访问，它有来自spinner API的spinner数据。我想编辑和更改数据，但当我执行编辑时，它不会显示特定列的任何数据。它没有保留价值。请帮助我如何继续

我想编辑访问列表。但我必须设置与我之前选择的相同的数据
case R.id.edit_visit_relative:
Intent intent = new Intent(getApplicationContext(), AddVisitsActivity.class);
intent.putExtra("customerName", custName);
intent.putExtra("customerId", custId);
intent.putExtra("visitDate", visitDate);
intent.putExtra("startTime", startTime);
intent.putExtra("endTime", endTime);
intent.putExtra("purpose", purpose);
intent.putExtra("purposeId", purposeId);
intent.putExtra("description", description);
startActivity(intent);
break;
