android – 回收视图膨胀不同的行： – 在绑定数据时获取异常

我正在使用不同的项目膨胀来处理Recyceview.当我没有绑定RecycleView的onBindViewHolder方法上的数据时它不会崩溃..
但是当我绑定onBindViewHolder中的数据而不是我得到异常时,请检查我的代码并让我知道我在哪里做错了.

package com.tv.practise.adapter;

  /**

public class RecycleDataAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder> {

private Context mContext;
private ArrayList<RecycleBen> data;

public static class SimpleText extends RecyclerView.ViewHolder {
    TextView first_data_tv;

    public SimpleText(View v) {
        super(v);
        this.first_data_tv = (TextView) v.findViewById(R.id.first_data_tv);
    }
}

public   class SimpleImage extends  RecyclerView.ViewHolder {
    ImageView second_data_iv;

    public SimpleImage(View v) {
        super(v);
        this.second_data_iv = (ImageView) v.findViewById(R.id.second_data_iv);
    }
}

public  class SimpleImageWithText extends  RecyclerView.ViewHolder {
    TextView third_data_tv;
    ImageView third_iv;

    public SimpleImageWithText(View v) {
        super(v);
        this.third_data_tv = (TextView) v.findViewById(R.id.third_data_tv);
        this.third_iv = (ImageView) v.findViewById(R.id.third_iv);
    }
}

public RecycleDataAdapter(Context mContext, ArrayList<RecycleBen> data) {
    this.mContext = mContext;
    this.data = data;
}

@Override
public  RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

    int listViewItemType = getItemViewType(viewType);
    View itemView;
    if(listViewItemType==1)
    {

        itemView = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.recycle_first_item, parent, false);

        return new SimpleText(itemView

        );

    }
    else if(listViewItemType==2)
    {
        itemView = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.recycle_fsecond_item, parent, false);
        return new SimpleImage(itemView);
    }
    else
    {
        itemView = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.recycle_third_item, parent, false);
        return new SimpleImageWithText(itemView);
    }



}

@Override
public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
    RecycleBen bean = data.get(position);

    if(holder.getItemViewType()==1)
    {
           /////HERE I AM GETTING THE EXCEPTION WHILE BINDIND DATA
        ((SimpleText)holder).first_data_tv.setText(bean.getName());

    }
    else if(holder.getItemViewType()==2)
    {

    }
    else {
          /////HERE I AM GETTING THE EXCEPTION WHILE BINDIND DATA((SimpleImageWithText)holder).third_data_tv.setText(bean.getName());
    }

}




@Override
public int getItemViewType(int position) {
    return Integer.parseInt(data.get(position).getType_row());
}

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

我绑定数据时的例外情况如下： –

原因是isCreateViewHolder(ViewGroup parent,int viewType).参数是视图类型,但不是位置.使用int listViewItemType = getItemViewType(viewType)不正确,因为位置应该传递给getItemViewType.

简而言之,您应该直接使用viewType并删除onCreateViewHolder中的listViewItemType.
