在我的情况下,我想从Spinner中获取所选项的Id。我的模型类中有两个字段,即id和name。我列出了所有数据并将其设置为适配器的列表。我尝试使用getSelectedItem()方法获取所选项的Id,但是我只能得到项目清单中的第一个id。
这是我的代码。
这是CustomEventType适配器代码。
这是我的代码。
public class ModifyEventFragment extends DialogFragment{
Context context;
CalEvent eve;
Project proj;
Spinner eventType,stage;
public static String eid,pid,type;
public static List<EventType> event_type;
public static List<ProjectStatus> cust_stage;
EditText where,when,who,notes;
String eve_type,stage_val,when_val,who_val,notes_val;
String modified_where,modified_who,modified_when,modified_notes;
public ModifyEventFragment(Project proj)
{
this.proj=proj;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.modify_project_event, container,
false);
context = rootView.getContext();
eventType = (Spinner) rootView.findViewById(R.id.modifyEventType);
stage =(Spinner) rootView.findViewById(R.id.modifyStage);
where = (EditText)rootView.findViewById(R.id.modifyWhere);
who = (EditText)rootView.findViewById(R.id.modifyWho);
when = (EditText)rootView.findViewById(R.id.modifyWhen);
notes =(EditText) rootView.findViewById(R.id.modifyNotes);
eve = CalEvent.getCalEvent(ProjectEventFragment.calevent.eve_id);
event_type = EventType.listAll();
CustomEventTypeAdapter adapter = new CustomEventTypeAdapter(context, event_type);
eventType.setAdapter(adapter);
type=((EventType)eventType.getSelectedItem()).et_id;
cust_stage = ProjectStatus.listAll();
CustomStatusAdapter adapter1 = new CustomStatusAdapter(context, cust_stage);
stage.setAdapter(adapter1);
where.setText(eve.followup_location.toString());
where.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
// TODO Auto-generated method stub
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub
}
@Override
public void afterTextChanged(Editable s) {
// TODO Auto-generated method stub
modified_where = s.toString();
}
});
who.setText(eve.person_met.toString());
who.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
// TODO Auto-generated method stub
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub
}
@Override
public void afterTextChanged(Editable s) {
// TODO Auto-generated method stub
modified_who = s.toString();
}
});
when.setText(eve.event_start.toString());
when.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
// TODO Auto-generated method stub
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub
}
@Override
public void afterTextChanged(Editable s) {
// TODO Auto-generated method stub
modified_when = s.toString();
}
});
notes.setText(eve.notes.toString());
notes.addTextChangedListener(new TextWatcher() {
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
// TODO Auto-generated method stub
}
@Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub
}
@Override
public void afterTextChanged(Editable s) {
// TODO Auto-generated method stub
modified_notes = s.toString();
}
});
Button save = (Button) rootView.findViewById(R.id.modifyeventsave);
save.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
eve.followup_location = modified_where;
eve.event_start = modified_when;
eve.person_met = modified_who;
eve.notes = modified_notes;
System.out.println("print type"+type);
eve.save();
ProjectEventFragment.adapter.notifyDataSetChanged();
}
});
return rootView;
}
这是CustomEventType适配器代码。
public class CustomEventTypeAdapter extends BaseAdapter{
Context ctx;
List<EventType> ps;
LayoutInflater inflater;
public CustomEventTypeAdapter(Context ctx,List<EventType> ps)
{
this.ctx=ctx;
this.ps=ps;
inflater = (LayoutInflater) ctx
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}
@Override
public int getCount() {
// TODO Auto-generated method stub
return ps.size();
}
@Override
public EventType getItem(int position) {
// TODO Auto-generated method stub
return ps.get(position);
}
@Override
public long getItemId(int position) {
// TODO Auto-generated method stub
return ps.get(position).getId();
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View rowView = convertView;
if (convertView == null)
rowView = inflater.inflate(R.layout.spinner_item_local, parent,
false);
TextView textView = (TextView) rowView.findViewById(R.id.spinner_item_text);
EventType proj = getItem(position);
try {
textView.setText(proj.name);
} catch (Exception e) {
}
return rowView;
}
有人可以帮我解决这个问题吗?
这个问题与IT技术有关。
