Android: Werte von Listview mit mehrzeiligem Layout erhalten

Question

Ich habe eine Listenansicht mit mehreren Zeilenlayouts (Radiogruppe, Text bearbeiten, Textansicht), mit Multiple-Choice-Modus. Ich möchte die ausgewählten Daten (vom Benutzer ausgewählte oder getippte Daten) auf einem Absenden-Button abrufen.

Dies ist der Code aus meiner Hauptdatei:

public class GraduatingSurvey extends Fragment { 


    private static final String LOGTAG = "log" ; 
    public String stdcode = "024-15-16079"; 
    Button submit; 
    RadioGroup radioGroup; 
    RadioButton radioButton; 
    EditText comment; 

    ArrayList<GraduatingSurveyModel> graduatingModelList; 
    ListView listView; 
    View view; 

    public GraduatingSurvey() { 
     // Required empty public constructor 
    } 


    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
          Bundle savedInstanceState) { 
     // Inflate the layout for this fragment 
     view = inflater.inflate(R.layout.fragment_graduating_survey, container, false); 
     submit = (Button) view.findViewById(R.id.btn_graduate_submit); 
     listView = (ListView) view.findViewById(R.id.graduate_list); 
     graduatingModelList = new ArrayList<GraduatingSurveyModel>(); 

     //handle submit form Event. 
     submit.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       final int child=listView.getAdapter().getCount(); 
       Log.i("radio", "child: " + child); 
       SparseBooleanArray checked = listView.getCheckedItemPositions(); //Is returning empty 
       Log.i("radio", "sparseArray: " + checked); 
       for(int i=0;i<child;i++) { 
        int type = listView.getAdapter().getItemViewType(i); 
        Log.i("radio", "type: " + type); 
        if(type == 2){ 
         // Want to retrieve data here 

        } 
        if(type == 0) 
        { 

        } 
        if(type == 1){ 

        } 

       } 

      } 
     }); 

     NetAsync(view); 
     return view; 
    } 

Dies ist der Adapter:

public class GraduatingSurveyAdapter extends ArrayAdapter<GraduatingSurveyModel> { 

    private static final int TYPE_ITEM1 = 0; 
    private static final int TYPE_ITEM2 = 1; 
    private static final int TYPE_ITEM3 = 2; 
    int type; 
    ArrayList<GraduatingSurveyModel> ArrayListSurvey; 
    int Resource; 
    Context context; 
    LayoutInflater vi; 
    public GraduatingSurveyAdapter(Context context, int resource, ArrayList<GraduatingSurveyModel> objects) { 
     super(context, resource, objects); 
     ArrayListSurvey = objects; 
     Resource = resource; 
     this.context = context; 
     vi = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    } 

    @Override 
    public int getItemViewType(int position) { 

     if (position == 14){ 
      type = TYPE_ITEM1; 
     } else if (position == 23 || position == 24 || position == 25){ 
      type = TYPE_ITEM2; 
     } 
     else 
     { 
      type= TYPE_ITEM3 ; 
     } 
     return type; 
    } 

    @Override 
    public int getViewTypeCount() { 
     return 3; 
    } 

    @Override 
    public View getView(final int position, View convertView, ViewGroup parent) { 

     ViewHolder holder; 
     //first Item or row is being created hence ConvertView is NULL 
     if(convertView == null){ 

      if (type == TYPE_ITEM2) { 
       convertView = vi.inflate(R.layout.graduates_survey_comment,null); 
       holder = new ViewHolder(); 
       holder.tv_question = (TextView) convertView.findViewById(R.id.graduate_question); 
       holder.tv_comment = (TextView) convertView.findViewById(R.id.graduate_comment); 
      } 
      else if (type == TYPE_ITEM1) { 
       convertView = vi.inflate(R.layout.graduates_survey_subheader,null); 
       holder = new ViewHolder(); 
       holder.tv_question = (TextView) convertView.findViewById(R.id.graduate_question); 
      } 
      else { 
       //infalte layout of normaltype 

       //Inflating items only once 
       convertView = vi.inflate(Resource,null); 
       holder = new ViewHolder(); 

       holder.tv_question = (TextView) convertView.findViewById(R.id.graduate_question); 
       holder.tv_comment = (TextView) convertView.findViewById(R.id.graduate_comment); 
       holder.rg = (RadioGroup) convertView.findViewById(R.id.graduate_radioGroup); 
       holder.rg.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() { 
        @Override 
        public void onCheckedChanged(RadioGroup group, int checkedId) { 
         /* RadioButton radioButton = (RadioButton) group.findViewById(checkedId); 
         Log.i("radio", "onCheckedChanged: " + radioButton + " " + checkedId); 
         notifyDataSetChanged();*/ 
         Integer pos = (Integer) group.getTag(); 
         GraduatingSurveyModel element = ArrayListSurvey.get(pos); 
         switch (checkedId) { 
          case R.id.graduate_sAgree: 
           element.current = GraduatingSurveyModel.ANSWER_ONE_SELECTED; 
           break; 
          case R.id.graduate_agree: 
           element.current = GraduatingSurveyModel.ANSWER_TWO_SELECTED; 
           break; 
          case R.id.graduate_uncertain: 
           element.current = GraduatingSurveyModel.ANSWER_THREE_SELECTED; 
           break; 
          case R.id.graduate_disagree: 
           element.current = GraduatingSurveyModel.ANSWER_FOUR_SELECTED; 
           break; 
          case R.id.graduate_sDisagree: 
           element.current = GraduatingSurveyModel.ANSWER_FIVE_SELECTED; 
           break; 
          default: 
           element.current = GraduatingSurveyModel.NONE; // Something was 

         } 


        } 
       }); 
      } 

      convertView.setTag(holder); 
     }else{ 
      //reuse code. (Inflate items only once then reuse them.) 
      holder = (ViewHolder) convertView.getTag(); 
     } 

     // get info from ArrayList(that came through JSON), and set it in the View. 

     if (type == TYPE_ITEM1) { 
      holder.tv_question.setText(ArrayListSurvey.get(position).getQuestion()); 
     } 
     else if (type == TYPE_ITEM2) { 
      holder.tv_question.setText(ArrayListSurvey.get(position).getQuestion()); 
     } 
     else{ 
      holder.rg.setTag(new Integer(position)); 
      holder.tv_question.setText(ArrayListSurvey.get(position).getQuestion()); 
      if(ArrayListSurvey.get(position).current != GraduatingSurveyModel.NONE){ 
       RadioButton r = (RadioButton) holder.rg.getChildAt(ArrayListSurvey.get(position).current); 
       r.setChecked(true); 
      }else{ 
       holder.rg.clearCheck(); 
      } 
     } 
     return convertView; 
    } 
    static class ViewHolder{ 
     private TextView tv_question; 
     private TextView tv_comment; 
     private LinearLayout lv_choices; 
     private RadioGroup rg; 

    } 
} 

Das ist mein Modell:

public class GraduatingSurveyModel { 

    public String question; 
    public String comment; 
    public String choices; 
    public String subHeading; 


    public int current = NONE; // hold the answer picked by the user, initial is NONE(see below) 
    public static final int NONE = 1000; // No answer selected 
    public static final int ANSWER_ONE_SELECTED = 0; // first answer selected 
    public static final int ANSWER_TWO_SELECTED = 1; // second answer selected 
    public static final int ANSWER_THREE_SELECTED = 2; // third answer selected 
    public static final int ANSWER_FOUR_SELECTED = 3; // forth answer selected 
    public static final int ANSWER_FIVE_SELECTED = 4; // forth answer selected 


    public GraduatingSurveyModel() { 

    } 

    public String getQuestion() { 
     return question; 
    } 

    public void setQuestion(String question) { 
     this.question = question; 
    } 

    public String getComment() { 
     return comment; 
    } 

    public void setComment(String comment) { 
     this.comment = comment; 
    } 

    public String getChoices() { 
     return choices; 
    } 

    public void setChoices(String choices) { 
     this.choices = choices; 
    } 

    public String getSubHeading() { 
     return subHeading; 
    } 

    public void setSubHeading(String subHeading) { 
     this.subHeading = subHeading; 
    } 
} 

Und dies ist das XML-Layout des Hauptfragments:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:padding="16dp" 
    android:background="@color/dialog_background" 
    android:orientation="vertical" 
    tools:context="iulms.iunc.edu.pk.iqraiulms.GraduatingSurvey" 
    android:id="@+id/main_layout"> 

    <ListView 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:id="@+id/graduate_list" 
     android:layout_alignParentLeft="true" 
     android:layout_alignParentStart="true" 
     android:layout_above="@+id/btn_graduate_submit" 
     /> 
    <Button 
     android:id="@+id/btn_graduate_submit" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:text="submit" 
     android:layout_alignParentBottom="true" 
     /> 
</RelativeLayout> 

Dies sind die Layouts für die verschiedenen Arten von Reihen in Listenansicht

Wie kann ich abrufen die Daten im Hauptfragment eingereicht?

Dank

Answer 1

Für diese Sie eine benutzerdefinierte Klasse mit Zeilenwerten wie, fügen Sie, dass

Arraylist<CustomClass> mnewList = new ArrayList(); 
Class CustomClass 
{ 
    private String edValues, 
    private int rowId, 
} 

usw.

Dann Implementieren auf Änderung

für Radiobutton Hörer erstellen/entfernen aktuell ausgewählte Elemente zu dieser benutzerdefinierten Liste.
