Question

我有一个包含微调器的片段。微调器将显示“ 90天”，“ 180天”和“ 365天”。我的问题是如何将微调器选择的项目传递到片段中。

我的片段代码部分是

      void PrevReqList(String enquiryStatusCode, final View rootView){
                final   ListView enquiriesList=(ListView)rootView.findViewById(R.id.req_list);
                lists.add(enquiriesList);


                ArrayList<String> statisticsDuration = new ArrayList<String>();
                statisticsDuration.add(getResources().getString(R.string.days90));
                statisticsDuration.add(getResources().getString(R.string.days180));
                statisticsDuration.add(getResources().getString(R.string.days365));

                ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this.getActivity(), R.layout.item_spinner_small_white, statisticsDuration);
                dataAdapter.setDropDownViewResource(R.layout.item_spinner);
                listDurationSpinner =(Spinner)rootView.findViewById(R.id.list_duration);
                listDurationSpinner.setAdapter(dataAdapter);
                listDurationSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
                    @Override
                    public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {

String item = parent.getItemAtPosition(position).toString();

             **How to pass from here to below?**

                    }

                    @Override
                    public void onNothingSelected(AdapterView<?> parent) {

                    }


                });

                SharedPreferences preferences = this.getActivity().getSharedPreferences(Common.preferenceName, Context.MODE_PRIVATE);
                String userName=preferences.getString(Common.userName,"");
                final TextView noItems=(TextView)rootView.findViewById(R.id.no_items);
                noItems.setVisibility(View.GONE);
                final String reqtype= this.getActivity().getIntent().getExtras().getString(Common.REQUISITIONTYPE);
                enquiriesList.setVisibility(View.GONE);
                int duration=0;
                if(listDurationSpinner.getSelectedItem().toString().equals(getResources().getString(R.string.days90))){
                    duration = 90;
                }
                else if(listDurationSpinner.getSelectedItem().toString().equals(getResources().getString(R.string.days180))){
                    duration=180;
                }
                else if(listDurationSpinner.getSelectedItem().toString().equals(getResources().getString(R.string.days365))){
                    duration=365;
                }

    // My remaining code


    }

如果我有任何错误请原谅。我是新手。

Answer 1

您可以像这样创建片段中的数据成员：

String spinnerSelectedItem;

然后，您可以像这样在onItemSelected()中初始化该成员：

@Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
           spinnerSelectedItem = statisticsDuration.get(position);
     }

此后，spinnerSelectedItem将包含用户选择的值。

尝试此代码。制作一种如下所示的方法...

    private void getData(String value){
    SharedPreferences preferences = this.getActivity().getSharedPreferences(Common.preferenceName, Context.MODE_PRIVATE);
    String userName=preferences.getString(Common.userName,"");
    final TextView noItems=(TextView)rootView.findViewById(R.id.no_items);
    noItems.setVisibility(View.GONE);
    final String reqtype= this.getActivity().getIntent().getExtras().getString(Common.REQUISITIONTYPE);
    enquiriesList.setVisibility(View.GONE);
    int duration=0;
    if(value.equals(getResources().getString(R.string.days90))){
        duration = 90;
    }
    else if(value.equals(getResources().getString(R.string.days180))){
        duration=180;
    }
    else if(value.equals(getResources().getString(R.string.days365))){
        duration=365;
    }

}

之后，选择微调器视图的项目。

  listDurationSpinner.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
            @Override
            public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {
                  getData(parent.getSelectedItem().toString());// check this
                   //or
                  getData(spiner.getSelectedItem().toString());
               }

            @Override
            public void onNothingSelected(AdapterView<?> parent) {

            }


        });

片段内部微调器的传递值
