如何將本地圖像（可繪制圖像文件）顯示到cardviewvia json. 我想離線加載圖像而不是使用畢加索庫我正在使用選項(xiàng)卡布局和我的 Frament.java@Nullable@Overridepublic View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { View rootView = inflater.inflate( R.layout.fragment, container, false); return rootView;}@Overridepublic void onViewCreated(View view, @Nullable Bundle savedInstanceState) { super.onViewCreated(view, savedInstanceState); final ArrayList<Website> babyList = Website.getbabyFromFile("baby&kids.json", getActivity()); adapter = new WebsiteAdapter(this, babyList); recyclerView = (RecyclerView) view.findViewById(R.id.recycler_view); recyclerView.setLayoutManager(new GridLayoutManager(getActivity(),2)); recyclerView.setAdapter(adapter);}

如果你有繪制文件夾下的本地圖片為所有一）myntra B）firstCry C）跳房子等等，那么你只是單純的需要得到基于URL正確繪制。您可以創(chuàng)建工廠類，它將為您提供@DrawableRes
public static @DrawableRes int getDrawable(String url){
if(url.contains("Myntra")) {
return R.drawable.myntra;
} else if(url.contains("Snapdeal")) {
return R.drawable.snapdeal;
}
// Add other if else to support other website url
}
這是修改后的 onBindViewHolder 方法。
@Override
public void onBindViewHolder(WebsiteAdapter.ViewHolder holder, int position) {
Website website = mDataSource.get(position);
holder.url.setText(website.getUrl());
holder.thumbnailImageView.setImageResource(getDrawable(website.getUrl()));
}
