ANDROID - ListView項目無法正常顯示

我做了一個應用程序，我正在ListView中顯示圖像。我列表項的高度很小，並且在列表的第9項中插入幾個後顯示我插入的第一個項。爲什麼會發生？ANDROID - ListView項目無法正常顯示

我認爲問題不在數據庫中，因爲當我點擊該項目並打開詳細信息屏幕時，它是正確的圖像。

我想不出是什麼問題！有任何想法嗎？

我的適配器是：

public class CustomAdapter extends BaseAdapter { 

    private List<Clothes> items; 
    private Context context; 
    private LayoutInflater inflater; 

    public CustomAdapter(Context _context, List<Clothes> _items){ 
     inflater = LayoutInflater.from(_context); 
     this.items = _items; 
     this.context = _context; 

    } 



    @Override 
    public int getCount() { 
     return items.size(); 
    } 

    @Override 
    public Object getItem(int position) { 
     return position; 
    } 

    @Override 
    public long getItemId(int position) { 
     return position; 
    } 

    @Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     Clothes clothes = items.get(position); 

     View view = convertView; 

     if (view == null) { 

      view = inflater.inflate(R.layout.cloth_item, null); 


      TextView category = (TextView) view.findViewById(R.id.tv_category); 
      TextView size = (TextView) view.findViewById(R.id.tv_size); 
      TextView style = (TextView) view.findViewById(R.id.tv_style); 
      TextView brand = (TextView) view.findViewById(R.id.tv_brand); 
      TextView state = (TextView) view.findViewById(R.id.tv_state); 
      ImageView photo = (ImageView) view.findViewById(R.id.list_image); 

      category.setText(clothes.getCategory()); 
      size.setText(clothes.getSize()); 
      style.setText(clothes.getStyle()); 
      brand.setText(clothes.getBrand()); 
      state.setText(clothes.getState()); 
      photo.setImageBitmap(BitmapFactory.decodeFile(clothes.getPhotograph())); 
     } 
     return view; 

    }  
}

而且我的名單是：

<RelativeLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    tools:context=".MainActivity" 
    android:background="#ffffff"> 

    <ListView 
     android:id="@+id/categorized_list" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:fastScrollEnabled="true" 
     />  

</RelativeLayout>

使用視圖持有者 – justDroid

查看綁定視圖列表這個問題..它會有所幫助http://stackoverflow.com/問題/ 6470089/why-did-the-listview-repeated-every-6th-item –

謝謝大家！是的，持有人創造了奇蹟！ – user5805577

佈局

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto"

    <ListView 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:id="@+id/listViewNotification" />

創建一個名爲list_item.xml

使用此：

@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    Clothes clothes = items.get(position); 
    View view = convertView; 
    if (view == null) { 
     view = inflater.inflate(R.layout.cloth_item, null); 
    } 
    TextView category = (TextView) view.findViewById(R.id.tv_category); 
    TextView size = (TextView) view.findViewById(R.id.tv_size); 
    TextView style = (TextView) view.findViewById(R.id.tv_style); 
    TextView brand = (TextView) view.findViewById(R.id.tv_brand); 
    TextView state = (TextView) view.findViewById(R.id.tv_state); 
    ImageView photo = (ImageView) view.findViewById(R.id.list_image); 
    category.setText(clothes.getCategory()); 
    size.setText(clothes.getSize()); 
    style.setText(clothes.getStyle()); 
    brand.setText(clothes.getBrand()); 
    state.setText(clothes.getState()); 
    photo.setImageBitmap(BitmapFactory.decodeFile(clothes.getPhotograph())); 
    return view; 
}
