ListViewが奇妙に更新されています

Question

以下はリストビューのカスタム行のレイアウトです。

そして、これは私のCustomAdapter

public class CustomAdapter extends ArrayAdapter<GEvent> { 


boolean hasLiked; 
boolean hasDisliked; 
FirebaseUser fbUser; 
ArrayList<String> uids; 
ArrayList<String> dUids; 
GEvent currentEvent; 

private TextView likeTextView; 
private TextView numberOfLikes; 
private TextView dislikeTextView; 
private TextView numberOfDislikes; 
private TextView readMoreButton; 
private TextView eventDetails; 
private TextView titleGevent; 
private ImageView eventPhoto; 
private TextView profileName; 
private TextView descriptionGevent; 

private String description; 
private String titleForGEvent; 
private String detailsGEvent; 
private boolean hasLoaded=true; 

private de.hdodenhof.circleimageview.CircleImageView circleImageView; 

private Context mContext; 

private boolean wantsToReadMore=false; 

String profilePhotoLink; 


PopupWindow pw; 

public CustomAdapter(Context context, GEvent[] resource) { 
    super(context, R.layout.custom_row , resource); 

    this.mContext = context; 
} 


@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    LayoutInflater inflater = LayoutInflater.from(getContext()); 

    final View customView = inflater.inflate(R.layout.example,parent,false); 

    final GEvent gEvent = getItem(position); 

    currentEvent = gEvent; 

    firebaseAuth = FirebaseAuth.getInstance(); 

    uid = firebaseAuth.getCurrentUser().getUid(); 



    titleGevent = (TextView) customView.findViewById(R.id.geventTitle); 
    descriptionGevent = (TextView) customView.findViewById(R.id.geventDescription); 
    profileName = (TextView) customView.findViewById(R.id.geventProfileName); 
    likeTextView = (TextView) customView.findViewById(R.id.likeTextViewGEvent); 
    numberOfLikes = (TextView) customView.findViewById(R.id.numberOfLikesGEvent); 
    numberOfDislikes =(TextView) customView.findViewById(R.id.numberOfDislikesGEvent); 
    dislikeTextView = (TextView) customView.findViewById(R.id.dislikeTextViewGEvent); 
    readMoreButton = (TextView) customView.findViewById(R.id.geventReadMoreButton); 
    eventPhoto = (ImageView) customView.findViewById(R.id.geventEventPhoto); 
    eventDetails = (TextView)customView.findViewById(R.id.geventDetails); 
    circleImageView = (CircleImageView) customView.findViewById(R.id.profile_image); 

    description = gEvent.getDescription(); 
    detailsGEvent = gEvent.getgEventDate()+"\n"+gEvent.getgEventTime()+"\n"+gEvent.getVenue1()+"\n"+gEvent.getVenue2()+"\n"+gEvent.getContactEmail()+"\n"+gEvent.getContactPhoneNumber(); 
    titleForGEvent = gEvent.getTitle(); 


    if(gEvent.isHasPhoto()){ 

     hasLoaded= false; 
     readMoreButton.setText("Loading"); 

    } 

    readMoreButton.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 



      if(hasLoaded) { 
       Log.i("CA","Entered hasLoaded Function"); 
       readMoreFunction(); 
      } 
      else 
       Toast.makeText(mContext,"Loading....",Toast.LENGTH_LONG).show(); 
     } 
    }); 





    titleGevent.setText(gEvent.getTitle()); 




    String uuid = gEvent.getUuid(); 
    Boolean hasPhoto = gEvent.isHasPhoto(); 



    profileName.setText(gEvent.getProfileUsername()); 


    if(hasPhoto) { 


     final long ONE_MEGABYTE = 1024 * 1024 * 5; 

     pathRef.getBytes(ONE_MEGABYTE).addOnSuccessListener(new OnSuccessListener<byte[]>() { 
      @Override 
      public void onSuccess(byte[] bytes) { 

       Bitmap picturel = BitmapFactory.decodeByteArray(bytes, 0, bytes.length); 

       ImageView imageView = (ImageView) customView.findViewById(R.id.geventEventPhoto); 

       Drawable d = new BitmapDrawable(mContext.getResources(),picturel); 

       imageView.setBackground(d); 

       Log.i("CA","Entered hasRetrieved Photo and update hasLoaded"); 

       readMoreButton.setText("Read More"); 

       hasLoaded=true; 

      } 
     }).addOnFailureListener(new OnFailureListener() { 
      @Override 
      public void onFailure(@NonNull Exception exception) { 
       // Handle any errors 
       Log.i("Error","Couldn't Download"); 
      } 
     }); 

    } 




    return customView; 
} 

ます。public void readMoreFunction（）{

Log.i("CA","Entered readMoreFunction Function"); 

    if(wantsToReadMore){   //wants to read less now 

     Log.i("CA","Entered Read Less Function"); 

     eventPhoto.setAlpha(1f); 
     descriptionGevent.setText(""); 

     eventDetails.setText(""); 

     readMoreButton.setText("Read More"); 

     titleGevent.setText(titleForGEvent); 

     wantsToReadMore=false; 

    } 
    else{       //Wants to read more 
     Log.i("CA","Entered Read More Function"); 
     eventPhoto.setAlpha(0.5f); 
     descriptionGevent.setText(description); 

      eventDetails.setText(detailsGEvent); 

     titleGevent.setText(""); 

     readMoreButton.setText("Read Less"); 

     wantsToReadMore=true; 

    } 

です

私の問題は、このCustomAdapterを呼び出すたびに、リストアイテムが1つしかないときは、それが完全に動作することです。ただし、複数のリストアイテムがあるときはいつも不思議な動作をします。たとえば、2つのアイテムがある場合はいつでも、最初のアイテムの「Read More」ボタンを押すと、それが動作しているデータが最初のアイテムそのものであることをログに表示しても、2番目のアイテムがトリガーされます。

2つ以上のアイテムがある場合、上記のパターンが観察されます。つまり、アイテムの[Read More]ボタンをクリックするたびに、リストビューの次のアイテムがトリガーされます。画像がロードされた後、または[Read More]ボタンが応答しなくても、「読み込み中」に固執することがあります。 私はバグを探して過去2日間頭を叩いています。皆さんが私を助けてくれることを願っています。アドバンスで感謝します。

PS： - "Load More"ボタンが外れています。 GEventクラスインサイド

Answer 1

booleanフィールドを作成し、getViewインサイド

class GEvent { 
    private boolean readMoreClicked; 

    public boolean isReadMoreClicked(){ 
     return readMoreClicked; 
    } 

    public void setReadMoreClicked(boolean readMoreClicked){ 
     this.readMoreClicked = readMoreClicked; 
    } 
} 

、

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

    .... 

    if(gEvent.isReadMoreClicked()) { 
     Log.i("CA","Entered More Less Function"); 
     ... 
    } else { 
     Log.i("CA","Entered Less More Function"); 
     ... 
    } 

    readMoreButton.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      if(hasLoaded) { 
       Log.i("CA","Entered hasLoaded Function"); 

       // user has clicked Read More. Save the state 
       gEvent.setReadMoreClicked(!gEvent.isReadMoreClicked()); 
       notifyDataSetChanged(); 

      } else { 
       Toast.makeText(mContext,"Loading....",Toast.LENGTH_LONG).show(); 
      } 
     } 
    }); 

    ... 
} 

それはいくつかの編集が必要な場合があります。しかし、私はあなたがそのアイデアを得ることを望みます。 :)
