这是我的要求我有sqlite db从服务器获取json响应并保存它并将该值设置为spinner其工作正常但是当我编辑listview时我需要编辑微调器的值将该值设置为微调器而不是获取我尝试了一切让我发布到目前为止我尝试过的内容: 这是我尝试设置微调器的适配器:
final ArrayList<Model_Account> arrayobj = new ArrayList<Model_Account>();
spinners_state_db = new Spinners_DB_State(getBaseContext());
final Spinner_DB_AccountManagers acmobj = new Spinner_DB_AccountManagers(getBaseContext());
这是将选择值设置为微调器的地方:
modelobj.setName(((edit_accnt.getString(edit_accnt.getColumnIndex(Model_Account.State)))));
int position=0;
position=spinner_state_Adapter.getPosition(modelobj);
spinner_state.setSelection(position);
总是得到位置-1不知道在哪里犯错了我使用材料旋转器!!
我的微调器类:

private static final int DATABASE_VERSION = 4;
private static final String DATABASE_NAME = "spinners.db";
