水平recyclerview中的图像左右转动

问题描述：

我正在尝试使用图像和一些文本等进行简单的水平回收视图。但是，由于某些原因，当我前后滚动时，图像正在切换并在错误的地方结束。水平recyclerview中的图像左右转动

的问题在于，没有在适配器一个疑问：

public class SponsoredAdvertsAdapter extends RecyclerView.Adapter<SponsoredAdvertsAdapter.SponsoredAdvertHolder> { 

    private Context context; 
    private List<CustomAdvert> adverts; 
    private boolean isBigScreen; 

    public SponsoredAdvertsAdapter(Context context, List<CustomAdvert> adverts) { 
     this.context = context; 
     this.adverts = adverts; 
     isBigScreen = ScreenUtil.isBigScreen(context); 
    } 

    @Override 
    public SponsoredAdvertsAdapter.SponsoredAdvertHolder onCreateViewHolder(ViewGroup parent, int viewType) { 
     View layoutView = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_search_popular_adverts_phone, null); 
     if (isBigScreen) { 
      layoutView = LayoutInflater.from(parent.getContext()).inflate(R.layout.item_search_popular_adverts_tablet, null); 
     } 
     return new SponsoredAdvertHolder(layoutView); 
    } 

    @Override 
    public void onBindViewHolder(final SponsoredAdvertHolder holder, int position) { 

     final CustomAdvert advert = adverts.get(position); 
     String title    = advert.getAdvert().getValidTextShort(); 

     holder.title.setText(title); 
     holder.unreadBadge.setText(context.getString(R.string.customer_tilbudsaviser_unread_advert)); 
     if (advert.isRead()) { 
      holder.unreadBadge.setVisibility(View.INVISIBLE); 
     } else { 
      holder.unreadBadge.setVisibility(View.VISIBLE); 
     } 

     if (holder.image != null) { 
      attachAdvertImage(holder.image, holder.imageView); 
     } else { 
      String logoUrl = ImageScaleUrlBuilder.getFixedWidthUrl(advert.getLogoUrl(), holder.imageView.getMeasuredWidth()); 
      ImageLoaderHelper.loadImageFromUrl(logoUrl, new ImageLoaderHelper.ImageLoadedCallback() { 
       @Override 
       public void onBitmapLoaded(Bitmap bitmap) { 
        holder.image = bitmap; 
        attachAdvertImage(bitmap, holder.imageView); 
       } 
      }); 
     } 

     AdvertActivity.startAdvertActivity(context, advert.getCustomer(), advert.getAdvert(), 0, null); 
    } 

    private void attachAdvertImage(final Bitmap image, final ImageView imageView) { 
     RunOnUIThread.post(new Runnable() { 
      @Override 
      public void run() { 
       imageView.setImageBitmap(image); 
      } 
     }); 
    } 

    @Override 
    public int getItemCount() { 
     return adverts.size(); 
    } 

    public class SponsoredAdvertHolder extends RecyclerView.ViewHolder { 

     private final View container; 
     private final ImageView imageView; 
     private final TextView title, unreadBadge; 
     private Bitmap image; 


     public SponsoredAdvertHolder(View itemView) { 
      super(itemView); 
      container = itemView.findViewById(R.id.item_search_popular_adverts_container); 
      imageView = (ImageView) itemView.findViewById(R.id.search_popular_advert_imageview); 
      title  = (TextView) itemView.findViewById(R.id.search_popular_advert_title); 
      unreadBadge = (TextView) itemView.findViewById(R.id.unread_badge); 
     } 
    } 
}

这里就是我的适配器设置为recyclerview代码：

sponsoredAdvertsAdapter = new SponsoredAdvertsAdapter(getContext(), adverts); 
     LinearLayoutManager linearLayoutManager = new LinearLayoutManager(getContext(), LinearLayoutManager.HORIZONTAL, false); 
     sponsoredAdvertsRecyclerView.setLayoutManager(linearLayoutManager); 
     sponsoredAdvertsRecyclerView.setAdapter(sponsoredAdvertsAdapter);

这里是recyclerview（XML）：

<LinearLayout 
     android:id="@+id/popular_searches_container" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:orientation="vertical" 
     android:layout_weight="1" 
     android:background="@color/white"> 

    <android.support.v7.widget.RecyclerView 
       android:id="@+id/popular_adverts_searches_list" 
       android:layout_width="match_parent" 
       android:layout_height="wrap_content" 
       android:orientation="horizontal"> 
      </android.support.v7.widget.RecyclerView> 

</LinearLayout>

而且该项目的XML：¨

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:padding="8dp" 
    android:id="@+id/item_search_popular_adverts_container"> 

    <ImageView 
     android:id="@+id/search_popular_advert_imageview" 
     android:layout_width="136dp" 
     android:layout_height="170dp" 
     android:gravity="bottom" 
     android:scaleType="fitXY" 
     android:layout_marginBottom="10dp" 
     android:layout_gravity="center_horizontal"/> 

    <TextView 
     android:id="@+id/search_popular_advert_title" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_gravity="center_horizontal" 
     android:textColor="@color/secondary_grey" 
     android:textSize="14sp" 
     android:text="Title"/> 

    <include 
     android:id="@+id/unread_badge" 
     layout="@layout/item_badge" 
     android:layout_height="wrap_content" 
     android:layout_width="wrap_content" 
     android:layout_gravity="center_horizontal" 
     android:layout_marginTop="3dp" 
     android:text="@string/customer_tilbudsaviser_unread_advert" 
     android:visibility="invisible" /> 

</LinearLayout>

我知道这是Recyclerviews的一个相当常见的问题，但即使在查看其他解决方案后，我似乎也无法让我的解决方案正常工作。

任何帮助感激，

你尝试到该项目的宽度和高度从'match_parent'到'wrap_parent'改变？ –

@HoangNguyen是的，我只是试图..没有区别。但我不知道为什么会解决这个问题。你有什么特别的理由提出这个建议？ – Langkiller

啊，我的坏，对不起。我误解你的问题。 –

答

林建议你使用图像库等的Glide（git link）与图像视图中显示。它会正确缓存图像并显示。通过更换此线

imageView.setImageBitmap（图像））

使用滑行;这可以解决这个问题;

到

Glide 
    .with(myFragment) 
    .load(bitmap) 
    .centerCrop() 
    .crossFade() 
    .into(myImageView);
