Expandable列表視圖適配器getView（）重複位置

當我向下滾動時，My ExpandableListView的適配器重複查看和圖像的位置是我的代碼。在這兩種情況下，我都沒有使用View holder和View holder，所以我面臨這個問題。Expandable列表視圖適配器getView（）重複位置

public View getGroupView(int groupPosition, boolean isExpanded, 
         View convertView, ViewGroup parent) { 

    View view = convertView; 
    String groupName = (String) getGroup(groupPosition); 

    if (view == null) { 
     LayoutInflater inf = (LayoutInflater) context 
       .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     view = inf.inflate(R.layout.group_item, null); 
     holder = new ViewHolder(); 

     holder.arrowImage = (ImageView) view.findViewById(R.id.imageView1); 
     setImageView(holder.arrowImage, groupPosition); 
     view.setTag(holder); 
     holder.groupName = (TextView) view.findViewById(R.id.laptop); 
     holder.groupName.setTypeface(null, Typeface.BOLD); 
     holder.groupName.setText(groupName); 

    } else { 
     holder = (ViewHolder) view.getTag(); 
     holder.groupName = (TextView) view.findViewById(R.id.laptop); 
     holder.groupName.setTypeface(null, Typeface.BOLD); 
     holder.groupName.setText(groupName); 
    } 

    return view; 

} 

public ImageView getImageView(int position) { 
    return images[position]; 
} 

public void setImageView(ImageView image, int position) { 
    images[position] = image; 
} 

static class ViewHolder { 
    ImageView arrowImage; 
    TextView groupName; 
}

不要被標籤拾取視圖

使用本

public View getGroupView(int groupPosition, boolean isExpanded, 
         View convertView, ViewGroup parent) { 

    View view = convertView; 
    String groupName = (String) getGroup(groupPosition); 

    LayoutInflater inf = (LayoutInflater) context 
       .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     view = inf.inflate(R.layout.group_item, null); 
     holder = new ViewHolder(); 

     holder.arrowImage = (ImageView) view.findViewById(R.id.imageView1); 
     holder.groupName = (TextView) view.findViewById(R.id.laptop); 
     holder.groupName.setTypeface(null, Typeface.BOLD); 
     holder.groupName.setText(groupName); 
     setImageView(holder.arrowImage, groupPosition); 
     view.setTag(holder); 

    return view; 

} 

public ImageView getImageView(int position) { 
    return images[position]; 
} 

public void setImageView(ImageView image, int position) { 
    images[position] = image; 
} 

static class ViewHolder { 
    ImageView arrowImage; 
    TextView groupName; 
}

這將防止圖像重複，並考慮每個視圖作爲一個新的觀點

感謝sourabh devpura但它不工作根據我的要求.. –

當我更改groupClicklistner中的組顏色，重複的位置也改變它的顏色.. –

@UmairIrshad請把你的新代碼在q uotation –
