auf Knopf klicken, um Daten von jeder Ansicht zu erhalten

Question

Ich erstelle dynamische listview programmatisch, beim Klicken auf bestimmte Ansicht ich öffne date dialog.and setze Datumswert auf bestimmte Ansicht, jetzt habe ich speichern Knopf, beim Klicken auf Speichern button ich will Wert jeder Ansicht aus der Listenzeile.

Das ist mein Code:

private void createlist(ArrayList<publicationcheckeddetail> pb) { 
     try { 
      listContainer.removeAllViews(); 
      final LayoutInflater inflater = (LayoutInflater)  getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
      LinearLayout mainlayout = new LinearLayout(MainActivity.this); 
      LinearLayout.LayoutParams mainlayoutparameter = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT); 
      mainlayout.setLayoutParams(mainlayoutparameter); 
      mainlayout.setOrientation(LinearLayout.VERTICAL); 
      for (int i = 0; i < pb.size(); i++) { 
       final ViewGroup viewgroup = (ViewGroup) inflater.inflate(R.layout.row_view, null); 
       final LinearLayout sublayout = new LinearLayout(MainActivity.this); 
       LinearLayout.LayoutParams sublayoutparameter = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT); 
       sublayout.setLayoutParams(sublayoutparameter); 
       sublayout.setOrientation(LinearLayout.HORIZONTAL); 
       sublayout.setGravity(Gravity.CENTER); 
       viewHolder = new ListViewHolder(); 
       viewHolder.addImage = (ImageView) viewgroup.findViewById(R.id.addImage); 
       viewHolder.addchildimage = (ImageView) viewgroup.findViewById(R.id.childimage); 
       viewHolder.date = (TextView) viewgroup.findViewById(R.id.txtDate); 
       viewHolder.color = (TextView) viewgroup.findViewById(R.id.childdata); 
       Bitmap bitmap = BitmapFactory.decodeByteArray(pb.get(i).getPub_image(), 0, pb.get(i).getPub_image().length); 
       viewHolder.addImage.setImageBitmap(bitmap); 
       viewHoldersCollection.add(viewHolder); 
       sublayout.addView(viewgroup); 
       mainlayout.addView(sublayout); 
       viewHolder.date.setOnClickListener(new View.OnClickListener() { 
        @Override 

        public void onClick(View v) { 
         int index = ((ViewGroup) sublayout.getParent()).indexOfChild(sublayout); 
        v1 = ((ViewGroup) sublayout.getParent()).getChildAt(index).findViewById(R.id.txtDate); 
         openDateDialogtoSelectDate(v1); 

        } 
       }); 
       viewHolder.color.setOnClickListener(new View.OnClickListener() { 
        @Override 

        public void onClick(View v) { 
         int index = ((ViewGroup) sublayout.getParent()).indexOfChild(sublayout); 
         colorview = ((ViewGroup) sublayout.getParent()).getChildAt(index).findViewById(R.id.childdata); 
         strcolor = selectcolor(colorview); 
        } 
       }); 

       } 

      listContainer.addView(mainlayout); 
      listContainer.requestLayout(); 


     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
    } 




private void openDateDialogtoSelectDate(View v1) { 
     try { 
      Calendar c = Calendar.getInstance(); 
      dialog = new DatePickerDialog(this, datePickerListener, year, month, day); 
      dialog.getDatePicker().setMinDate(System.currentTimeMillis() - 1000); 
      dialog.show(); 

     } catch (Exception e) { 
      e.printStackTrace(); 

     } 
    } 

    public DatePickerDialog.OnDateSetListener datePickerListener = new DatePickerDialog.OnDateSetListener() { 
     public void onDateSet(DatePicker view, int selectedYear, 
           int selectedMonth, int selectedDay) { 
      year = selectedYear; 
      month = selectedMonth; 
      day = selectedDay; 
      tv = (TextView) v1.findViewById(R.id.txtDate); 

      tv.setText(new StringBuilder().append(day).append("-") 
        .append((month + 1)).append("-").append(year) 
        .append(" ")); 
} 
} 

Answer 1

einfach, durchqueren die Linearlayout (mainlayout)

 int childCount=mainlayout.getChildCount(); 

    for(int i=0;i<childCount;i++) 
    { 
      View v=mainlayout.getChildAt(i); 
      TextView txtDate=(TextView)v.findViewById(R.id.txtDate); //get the date value 
      String strDate= txtDate.getText().toString(); 


      // do other operations 
    } 

Answer 2

Möglicherweise möchten Sie versuchen, eine CustomListView zu verwenden. Diese sind nicht so schwer zu verwenden und sie haben eine nette Methode, die Sie überschreiben können getView().

@Override 
public View getView(final int position, View convertView, ViewGroup parent) { 
    LayoutInflater inflater = (LayoutInflater) context 
      .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    final View rowView = inflater.inflate(R.layout.settingsrowlayout, parent, false); 

    Button button = (Button)rowView.findViewById(R.id.btnChange); 

    //What you want to happen when the button in the generated ListView using a CustomListView to do. 
} 

Ich hoffe, das macht Sinn, benutzerdefinierte Listenansichten sind sehr hilfreich und ein gutes Werkzeug
