Question

我有一个包含微调器的android项目，它使用休息服务并且能够动态获取数据问题是当我点击按钮而不是微调器时它会获取数据我尝试在微调器上设置setOnClickListener函数，但它不起作用代码是

    private  Context mContext=HourlyEntry.this;
private Spinner s1;
private String m_DepartmentID=null;
private ArrayList<String> m_Department_list;
private ArrayList<String> m_DepartmentID_list;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_hourly_entry);


    s1=(Spinner)findViewById(R.id.spinner1);


    s1.setOnClickListener(this);

}





  @Override
    public void onClick(View v) {


        if (v == s1)
        {
          JSONObject login = new JSONObject();
        try
        {
        login.put("EmployeeID","1");
        //login.put("Password", etCountry.getText().toString());

        JSONObject finaldata = new JSONObject();
        finaldata.put("ProjectRequest", login);


          final ConnectToServer connect = new ConnectToServer();
            connect.extConnectToServer(HourlyEntry.this,
                             new ConnectToServer.Callback() 
            {
                public void callFinished(String result)
                {
                    //Toast.makeText(getBaseContext(), result,
                                              Toast.LENGTH_LONG).show();

                    JSONObject resp = null;
                    try 
                    {
                        resp = new JSONObject(result);
                        Toast.makeText(getBaseContext(), result, Toast.LENGTH_LONG).show();
                        JSONObject Login1Result = resp.getJSONObject("ProjectResult");
                        JSONArray DepartmentDetails = Login1Result.getJSONArray("ProjectDetails");
                        //String strMessage = Login1Result.getString("message");
                     Toast.makeText(getBaseContext(), Login1Result.getString("ProjectDetails"), Toast.LENGTH_LONG).show();
                //  List<String> list = new ArrayList<String>();
                        if (!Login1Result.getString("ProjectDetails").equalsIgnoreCase("null")) 
                    {
                        //JSONArray DepartmentDetails = Login1Result.getJSONArray("ProjectDetails");

                        m_Department_list = new ArrayList<String>();
                        m_DepartmentID_list = new ArrayList<String>();
                        for (int i = 0; i < DepartmentDetails.length(); i++) 
                        {
                            JSONObject m_DepartmentDetails = DepartmentDetails.getJSONObject(i);
                            if (!m_DepartmentDetails.getString("ProjectName").equalsIgnoreCase("null")&& !m_DepartmentDetails.getString("ProjectName").equalsIgnoreCase("")) 
                            {
                                //list.add(m_DepartmentDetails.getString("ProjectName"));
                                m_Department_list.add(m_DepartmentDetails.getString("ProjectName"));
                                //Toast.makeText(getBaseContext(), m_DepartmentDetails.getString("ProjectName"), Toast.LENGTH_LONG).show();
                            }
                            if (!m_DepartmentDetails.getString("ProjectID").equalsIgnoreCase("null")&& !m_DepartmentDetails.getString("ProjectID").equalsIgnoreCase("")) 
                            {
                                m_DepartmentID_list.add(m_DepartmentDetails.getString("ProjectID"));

                            }
                        }
                    }

                        s1 = (Spinner) findViewById(R.id.spinner1);



                        final ArrayAdapter<String> adapter = new ArrayAdapter<String>(mContext, R.layout.spin,m_Department_list);
                    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

                    s1.setAdapter(adapter);
                    if (m_DepartmentID_list.contains(m_DepartmentID)) 
                    {
                        s1.setSelection(m_DepartmentID_list.indexOf(m_DepartmentID));
                    }
                    }

                    catch (final JSONException e)
                    {

                    }

                }
                    }, "http://aapnapms.azurewebsites.net/Service1/Project", finaldata,
                    "POST");
            connect.execute(finaldata);

        if(!validate())
            Toast.makeText(getBaseContext(), "Enter some data !", Toast.LENGTH_LONG).show();
        }
         catch (Exception e) {
            Log.d("InputStream", e.getLocalizedMessage());

使用

 s1.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> arg0, View arg1,
                int arg2, long arg3) {
            // TODO Auto-generated method stub

        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub

        }
    });

而不是

s1.setOnClickListener(this);

动态微调器消耗休息服务在OnClickListener上创建问题
