Question

am使用Picasso库获取图像URL，但随后该应用程序停止了。这是我的错误日志和listAdapter的示例

@Override
    public View getView(int position,  View convertView,  ViewGroup parent) {
        final View result;

        ViewHolder holder;
        if ( convertView == null ) {
            LayoutInflater inflater=LayoutInflater.from ( mCtx );

            convertView=inflater.inflate ( R.layout.listtips , null , true );
            holder=new ViewHolder ();
            holder.time=(TextView) convertView.findViewById ( R.id.time );
            holder.input=(TextView) convertView.findViewById ( R.id.input );

            holder.match=(TextView) convertView.findViewById ( R.id.match );
            holder.bookies=(TextView) convertView.findViewById ( R.id.bookies );
            holder.predict=(TextView) convertView.findViewById ( R.id.predict );
            holder.results=(TextView) convertView.findViewById ( R.id.results );
            holder.imgURl=(ImageView) convertView.findViewById ( R.id.image ) ;





            result=convertView;

            convertView.setTag ( holder );
        } else {
            holder=(ViewHolder) convertView.getTag ();
            result=convertView;
        }

        Animation animation=AnimationUtils.loadAnimation ( mCtx , (position > lastPosition) ? R.anim.load_down_anim : R.anim.load_up_anim );
        result.startAnimation ( animation );
        lastPosition=position;

        tips tips=tipsList.get ( position );
        holder.time.setText ( tips.getTime () );

        holder.input.setText ( tips.getInput () );

        holder.match.setText ( tips.getMatch () );
        holder.bookies.tip.setText ( tips.getBookies () );
        holder.predict.setText ( tips.getPredict () );
        holder.results.setText ( tips.getResults () );

        Picasso.with(mCtx).load(tips.getStatus ()).into(holder.imgURl);

            return convertView;
        }

Answer 1

错误很明显

路径不能为空。在com.squareup.picasso.Picasso.load

在tips.getStatus()中的含义Picasso.with(mCtx).load(tips.getStatus ())为空或空白

解决方案：确保getStatus返回默认值，如果空白

（您可以使用lang3库StringUtils.isBlank()）

我一直在尝试使用json将数据放入列表
