Listview獲取重新創建並更改以前的視圖

Question

我有一個ListView，其中我動態地膨脹4個不同的佈局。在列表視圖中的每個項目中，常見的事情是3個按鈕。喜歡，不喜歡，評論。所以當我們點擊它時，就會顯示與圖片相關的個人資料圖片。和厭惡和評論一樣。 問題出現了，當我點擊它會顯示正確的數據，但當我向下滾動，當該項目不在視圖中時，當我滾動查看該項目時，它會改變其視圖與其他一些按鈕單擊。 這發生在敵人的ListView 每一項都需要一個緊急援助getView的 代碼：

@Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     // TODO Auto-generated method stub 
     mInflater= LayoutInflater.from(mContext); 
      pos=position; 
     if(convertView==null){ 
      Log.e("--------Inside---------", "convertView==null"); 
      holder= new Holder(); 
      convertView = mInflater.inflate(R.layout.custom_stream_list, null); 
      holder.childView= (LinearLayout) convertView.findViewById(R.id.view_to_inflate); 
      holder.myGallery= (Gallery) convertView.findViewById(R.id.myGallery_stream); 
      holder.like= (ImageView) convertView.findViewById(R.id.like_stream); 
      holder.dislike =(ImageView) convertView.findViewById(R.id.dislike_stream); 
      holder.comment = (ImageView) convertView.findViewById(R.id.comment_stream); 
      holder.commentLayout = (RelativeLayout) convertView.findViewById(R.id.comment_view_to_inflate); 
      holder.comment_name = (TextView) convertView.findViewById(R.id.comment_name); 
      holder.comment_description = (TextView) convertView.findViewById(R.id.comment_description); 
      holder.comment_time = (TextView) convertView.findViewById(R.id.comment_time); 

      convertView.setTag(holder); 
     }else { 
      Log.e("--------Inside---------", "else Statement"); 
      holder= (Holder) convertView.getTag(); 
     } 
     holder.myGallery.setVisibility(View.INVISIBLE); 

     holder.like.setTag(holder); 
     holder.dislike.setTag(holder); 
     holder.comment.setTag(holder); 



     holder.myGallery.setSpacing(5); 


     holder.like.setOnClickListener(this); 
     holder.dislike.setOnClickListener(this); 
     holder.comment.setOnClickListener(this); 


     if((position%4)==0){ 
      Log.e("--------Inside---------", "position==0"); 
      followLayoutView = mInflater.inflate(R.layout.abc, null); 
      holder.news_titile=(TextView) followLayoutView.findViewById(R.id.news_article_titile); 
      holder.news_description= (TextView) followLayoutView.findViewById(R.id.news_article_description); 
      holder.childView.removeAllViews(); 
      holder.childView.addView(followLayoutView); 

     } if((position%4)==1){ 
      Log.e("--------Inside---------", "position==1"); 
      followLayoutView1 = mInflater.inflate(R.layout.xyz, null); 
      holder.match_event_title= (TextView) followLayoutView1.findViewById(R.id.match_events_stream_titile); 
      holder.match_event_time= (TextView) followLayoutView1.findViewById(R.id.following_time); 
      holder.match_event_description= (TextView) followLayoutView1.findViewById(R.id.match_events_stream_description); 
      holder.childView.removeAllViews(); 
      holder.childView.addView(followLayoutView1); 


     } if((position%4)== 2){ 
      Log.e("--------Inside---------", "position==2"); 
      followLayoutView2 = mInflater.inflate(R.layout.pqr, null); 
      holder.match_event_title= (TextView) followLayoutView2.findViewById(R.id.match_events_stream_titile); 
      holder.match_event_time= (TextView) followLayoutView2.findViewById(R.id.following_time); 
      holder.match_event_description= (TextView) followLayoutView2.findViewById(R.id.match_events_stream_description); 
      holder.childView.removeAllViews(); 
      holder.childView.addView(followLayoutView2); 

     } if((position%4)==3){ 
      Log.e("--------Inside---------", "position==3"); 
      followLayoutView3 = mInflater.inflate(R.layout.mno, null); 
      holder.video_background= (ImageView) followLayoutView3.findViewById(R.id.video_background); 
      holder.play = (ImageView) followLayoutView3.findViewById(R.id.video_play); 
      holder.childView.removeAllViews(); 
      holder.childView.addView(followLayoutView3); 


     } 

     return convertView; 
    }

我猜你沒有使用持有人的動態列表。 使用持有人模式爲了避免這個問題。 希望這個鏈接幫助。 http://www.vogella.com/articles/AndroidListView/article.html
