recyclerview

Question

public class AdapterRecycleView extends RecyclerView.Adapter<AdapterRecycleView         .BaseViewHoder> {     private Context context;     private List<ItemMsg> itemMsgList;          @Override public BaseViewHoder onCreateViewHolder(ViewGroup parent, int viewType) {     View view= LayoutInflater.from(parent.getContext()).inflate(R.layout             .item_layout, parent, false);     return new BaseViewHoder(view); }from（context）就会报错，求大神解释下为啥会这样，看别人这样写没事class BaseViewHoder extends RecyclerView.ViewHolder {     private ImageView imageView;     private TextView textView;     public BaseViewHoder(View itemView) {         super(itemView);         imageView=(ImageView)itemView.findViewById(R.id.image);         textView=(TextView)itemView.findViewById(R.id.text);         imageView.setOnClickListener(new View.OnClickListener() {             @Override             public void onClick(View v) {                 Intent intent=new Intent(v.getContext(),MainActivity.class);                v.getContext().startActivity(intent);             }         });     }在后面也是这样，非要用v.getContext()   不能用context

Answer 1

private Context context;你定义的context没有赋初值，是空指针
