【问题描述】：

我试图从异步类中获取输出并在片段侧的网格视图中使用 我确定我的输入是正确的

 public void processFinish(movieList output) 
        String[] movieId=output.getMovieId();
        String[] movieImg=output.getMovieId();
        boolean response=output.getStatus();
        if(response==true)
            GridView gridView = (GridView) view.findViewById(R.id.gridView_cover);
            MovieAdapter = new movieGridAdapter(getActivity(), movieImg);
            gridView.setAdapter(MovieAdapter);

网格适配器

public View getView(int position, View view, ViewGroup viewGroup) 
        ImageView imageView;
        if(view==null)
            imageView= new ImageView(mContext);
            // imageView.setLayoutParams(new GridView.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.MATCH_PARENT));
            imageView.setScaleType(ImageView.ScaleType.FIT_XY);

        
        else
        
            imageView=(ImageView) view;

        

        Picasso.with(mContext).load(image_base_url+imgs[position]).into(imageView);
        //Log.v(movieGridAdapter.class.getSimpleName(),"http://image.tmdb.org/t/p/w500/"+imgs[position]);

        return imageView;
    

【参考方案1】：

if(view==null)
            view = inflater.inflate(R.layout.YOUR_ADAPTER_LAYOUT, null);
            imageView= new ImageView(mContext);
            // imageView.setLayoutParams(new GridView.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT,ViewGroup.LayoutParams.MATCH_PARENT));
            imageView.setScaleType(ImageView.ScaleType.FIT_XY);
    

你没有为你的 gridview 扩展布局，因此你什么都看不到！
