Android listview with checkbox issue

Question

Если я нажму на этот флажок, это значит, что он будет снят во время прокрутки и наоборот. Также я хочу обновить фрагмент дома после щелчка по флажку. Кто-нибудь дает решение исправить эти два вопроса?

customViewHolder.checkBox.setChecked(feedItem.isSelected()); 

customViewHolder.checkBox.setTag(position); 

customViewHolder.checkBox.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() { 
    @Override 
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { 
     //set your object's last status 
     //feedItem.setSelected(isChecked); 
     //customViewHolder.checkBox.setTag(position); 
     int getPosition = (Integer) buttonView.getTag(); // Here we get the position that we have set for the checkbox using setTag. 
     feedItemList.get(getPosition).setSelected(buttonView.isChecked()); // Set the value of checkbox to maintain its state. 
    } 
}); 

if(!feedItem.getLikedStatus().isEmpty()) { 
    if(feedItem.getLikedStatus().matches("liked")) { 
     customViewHolder.checkBox.setChecked(true); 
    } else { 
     customViewHolder.checkBox.setChecked(false); 
    } 
} 

//set Like Count 
if(!feedItem.getLikedCount().isEmpty()) { 
    if(feedItem.getLikedCount().matches("1")) { 
     customViewHolder.likedUserName.setVisibility(View.VISIBLE); 
     customViewHolder.likedUserName.setText(feedItem.getLikedUserName()); 
     customViewHolder.likeImageView.setVisibility(View.VISIBLE); 
    } else if(feedItem.getLikedCount().matches("0")) { 
     customViewHolder.likedUserName.setVisibility(View.GONE); 
     customViewHolder.likeImageView.setVisibility(View.GONE); 
    } else { 
     customViewHolder.likedUserName.setVisibility(View.VISIBLE); 
     customViewHolder.likedUserName.setText(feedItem.getLikedCount()+" likes"); 
     customViewHolder.likeImageView.setVisibility(View.VISIBLE); 
    } 
} 

customViewHolder.checkBox.setOnClickListener(new View.OnClickListener() { 
    @Override 
    public void onClick(View v) { 
     if(!feedItem.getLikedCount().isEmpty()) { 
      if(feedItem.getLikedCount().matches("0")) { 
       if(customViewHolder.checkBox.isChecked()) { 
        customViewHolder.likeImageView.setVisibility(View.VISIBLE); 
        customViewHolder.likedUserName.setVisibility(View.VISIBLE); 
        customViewHolder.likedUserName.setText(userName); 
        //call like url 
        postLikeUnlike(feedItem.getPostID(),like); 
       } else { 
        //call unlike url 
        customViewHolder.likeImageView.setVisibility(View.GONE); 
        customViewHolder.likedUserName.setVisibility(View.GONE); 
        postLikeUnlike(feedItem.getPostID(), unlike); 
       } 
      } else { 
       if(customViewHolder.likedUserName.getText().toString().matches(userName)) { 
        if (customViewHolder.checkBox.isChecked()) { 
         customViewHolder.likeImageView.setVisibility(View.VISIBLE); 
         customViewHolder.likedUserName.setVisibility(View.VISIBLE); 
         customViewHolder.likedUserName.setText(userName); 
         //call like url 
         postLikeUnlike(feedItem.getPostID(),like); 
        } else { 
         customViewHolder.likeImageView.setVisibility(View.GONE); 
         customViewHolder.likedUserName.setVisibility(View.GONE); 
         //call unlike url 
         postLikeUnlike(feedItem.getPostID(),unlike); 
        } 
       } else { 
        if (customViewHolder.checkBox.isChecked()) { 
         System.out.println("checkbox already checked"); 
         customViewHolder.i = customViewHolder.i + 1; 
         customViewHolder.likedUserName.setText(String.valueOf(customViewHolder.i) + " likes"); 
         //call like url 
         postLikeUnlike(feedItem.getPostID(),like); 
        } else { 
         System.out.println("i1 value" + customViewHolder.i); 
         customViewHolder.i = customViewHolder.i - 1; 
         customViewHolder.likedUserName.setText(String.valueOf(customViewHolder.i) + " likes"); 
         //call unlike url 
         postLikeUnlike(feedItem.getPostID(),like); 
        } 
       }

I Столкнулся с той же проблемой для рейтингаBar. Вот мой код. Вам просто нужно установить CHECKBOX вместо RatingBar.

public class MainActivity extends AppCompatActivity { 

String ratedValue; 
ListView ratingList; 

private static final String[] listItems = {"1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11","12", "13", "14","15", "16", "17", "18", "19", "20" }; 




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

    ratingList = (ListView)findViewById(R.id.ratingList); 

    ArrayList<RowModel> list = new ArrayList<RowModel>(); 

    for (String s : listItems) { 
     list.add(new RowModel(s)); 
    } 

    ratingList.setAdapter(new RatingAdapter(list)); 
} 

private RowModel getModel (int position) { 
    return ((RatingAdapter)ratingList.getAdapter()).getItem(position); 
} 

class RatingAdapter extends ArrayAdapter<RowModel> { 
    RatingAdapter(ArrayList<RowModel> list) { 
     super(MainActivity.this, R.layout.list_row, R.id.idView, list); 
    } 

    class ViewHolder { 
     RatingBar ratingBar = null; 

     ViewHolder(View view) { 
      this.ratingBar = (RatingBar)view.findViewById(R.id.ratingBar1); 
      this.ratingBar.setEnabled(false); 
     } 
    } 

    public View getView(int position, View convertView, ViewGroup parent) { 
     View row = super.getView(position, convertView, parent); 

     ViewHolder holder = (ViewHolder)row.getTag(); 

     if (holder == null) { 
      holder = new ViewHolder(row); 
      row.setTag(holder); 

      RatingBar.OnRatingBarChangeListener l = new RatingBar.OnRatingBarChangeListener() { 
       @Override 
       public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromUser) { 
        Integer myPosition = (Integer)ratingBar.getTag(); 
        RowModel model = getModel(myPosition); 

        model.rating = rating; 

        LinearLayout parent = (LinearLayout)ratingBar.getParent(); 
        TextView label = (TextView)parent.findViewById(R.id.ratingMessage); 

        label.setText("Rating : " + rating + "/5"); 
       } 
      }; 

      holder.ratingBar.setOnRatingBarChangeListener(l); 
     } 
     RowModel model = getModel(position); 

     holder.ratingBar.setTag(new Integer(position)); 
     holder.ratingBar.setRating(model.rating); 

     return (row); 
    } 
} 

class RowModel { 
    String label; 
    float rating = 0.0f; 

    RowModel(String label) { 
     this.label = label; 
    } 

    public String toString() { 
     if (rating >= 3.0) { 
      return (label.toUpperCase()); 
     } 
     return label; 
    } 
} 

}
