传递包到片段的错误

Question

有人可以帮我检查我的代码吗？我想通过Information和WorkForce数据到WorkDetailsTable并通过单击按钮保存它们。我尝试了许多方法，它不起作用。请帮助我...从昨天开始我一直在这里。这完全令人沮丧！

TabPagerAdapter.java

public class TabPagerAdapter extends FragmentStatePagerAdapter { 
     public TabPagerAdapter(FragmentManager fm) { 
      super(fm); 
      // TODO Auto-generated constructor stub 
     } 

     @Override 
     public Fragment getItem(int i) { 

      switch (i) { 
       case 0: 

        return Information.newInstance("name"); 
       case 1: 

        return WorkForce.newInstance("SubCon"); 
       case 2: 


        return WorkDetailsTable.newInstance(); 
      } 
      return null ; 

     } 

     @Override 
     public int getCount() { 
      // TODO Auto-generated method stub 
      return 3; //No of Tabs you can give your number of tabs 
     } 

Information.java

public class Information extends Fragment implements View.OnClickListener { 
     private Spinner spinner, spinner2, spinner3; 

     private static String a; 
     public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
      View info = inflater.inflate(R.layout.information, container, false); 
      dialog = new DateDialog(); 
      spinner = (Spinner)info.findViewById(R.id.spinner); 
      addItemsOnSpinner(); 
      a= spinner.getSelectedItem().toString(); 
      return info; 
     } 

    public static Information newInstance(String a) 
     { 
      Information fragment=new Information(); 
      Bundle bundle=new Bundle(); 
      bundle.putString("a",a); 
      fragment.setArguments(bundle); 
      return fragment; 
     } 

    public void addItemsOnSpinner() { 
      List<String> list = new ArrayList<String>(); 
      list.add("1 "); 
      list.add("2"); 
      ArrayAdapter<String> adapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_spinner_dropdown_item, list); 
      adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); 
      spinner.setAdapter(adapter); 



     } 

WorkForce.java

public class WorkForce extends Fragment { 
     private static EditText txt1; 
     private static String subCon; 
     public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
      View work = inflater.inflate(R.layout.workforce, container, false); 
      txt1 = (EditText) work.findViewById(R.id.editText); 
      subCon = txt1.getText().toString(); 
      return work; 
     } 

     public static WorkForce newInstance(String subCon) { 

      WorkForce f = new WorkForce(); 
      Bundle bundle = new Bundle(); 
      bundle.putString("subCon", subCon); 
      f.setArguments(bundle); 
      return f; 
     } 
    } 

WorkDetailsTable.java

private com.example.project.project.API.InfoAPI ts; 
     private com.example.project.project.API.WorkDetailsAPI WD; 
     private com.example.project.project.API.WorkForceAPI WF; 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { 
      super.onCreate(savedInstanceState); 
      View workDetails = inflater.inflate(R.layout.tableworkdetails, container, false); 
      getActivity().setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); 
      spinnerTra = (Spinner) workDetails.findViewById(R.id.spinner6); 
    addItemsOnSpinner(); 
    WD = new com.example.project.project.API.WorkDetailsAPI(getActivity()); 
      ts = new com.example.project.project.API.InfoAPI(getActivity()); 
      WF = new com.example.project.project.API.WorkForceAPI(getActivity()); 
     return workDetails; 
     } 

     public static WorkDetailsTable newInstance() { 

     final WorkDetailsTable f = new WorkDetailsTable(); 
     final Bundle bundle = new Bundle(); 
     final String name = bundle.getString("a"); 
     final String subContractors = bundle.getString("subCon"); 
     btn1.setOnClickListener(new View.OnClickListener() { 
      public void onClick(View arg0) { 
       ts.insertTimeSheet(name); 
       WF.insertWorkForce(subContractors); 

      } 
     }); 
     f.setArguments(bundle); 
     return f; 
    } 

InfoAPI.java

public class InfoAPI { 
    private SQLiteDatabase database; 
    private MyDatabaseHelper dbHelper; 
      ...... 

    public long insertTimeSheet(String name,String weather,String date,String status) 
    { 
     database=dbHelper.getWritableDatabase(); 
     ContentValues values=new ContentValues(); 
     values.put(MyDatabaseHelper.Name,name); 
     database.insert(MyDatabaseHelper.TABLE_INFO,null,values); 
     database.close(); 
     return 0 ; 

    } 

} 

WorkForceAPI.java

public class WorkForceAPI { 
    private SQLiteDatabase database; 
    private MyDatabaseHelper dbHelper; 

       ....... 
    public long insertWorkForce(String subcontractors,String numberOfPerson,String numberOfHours) 
    { 

     database=dbHelper.getWritableDatabase(); 
     ContentValues values1=new ContentValues(); 
     values1.put(MyDatabaseHelper.Subcontractors,subcontractors); 
     database.close(); 
     return 0 ; 

    } 

} 

错误：

Error:(145, 17) error: non-static variable ts cannot be referenced from a static context 
Error:(146, 17) error: non-static variable WF cannot be referenced from a static context 

Answer 1

在你staticnewInstance功能你是指ts和WF这是实例属性。

您应该在其中一个实例方法中设置OnClickListener，例如onCreateView或onViewCreated等
