android 对象数组简单使用

首先看下数据返回结构：

{"status":"ok","data":{"list":["P1248","P0002","P0004","P0004","P0002"]},"token":{"uid":"13573111","openid":"oBPBmw0jqu3tyrtyhreywYOiK60SaJHq462kcIddss","loginid":"fdb5a89d69f5a8eb246hrthrthrhdherj4f9b9173c99ecfdfdsfsds"}}

数据请求：

  //历史请求
    @SuppressLint("StaticFieldLeak")
    class HisTask extends AsyncTask<String, Void, CodeHisResponse> {

        @Override
        protected CodeHisResponse doInBackground(String... strings) {
            return DataInterface.hisResponse(hisdata);
        }

        @Override
        protected void onPreExecute() {
            super.onPreExecute();
            showProgressDialog();
        }

        @Override
        protected void onPostExecute(CodeHisResponse result) {
            super.onPostExecute(result);
            dismissProgressDialog();
            if (result == null) {
                Toast.makeText(CodeActivity.this, R.string.net_response, Toast.LENGTH_SHORT).show();
                return;
            }
            if (result.getData() != null && result.getStatus().equals("ok")) {
                CodeHisResponse.DataBean hisBean = result.getData();
                hisAdapter.addList(hisBean);
            } else {
                toast(result.getMessage());
            }
        }
    }

适配器器：

 /**
     * 历史列表填充器BaseAdapter
     */
    class HisAdapter extends RecyclerView.Adapter<HisAdapter.ViewHolder> implements View.OnClickListener {
        private Context mContext;
        private List<String> hisData = new ArrayList<>();
        //声明自定义的监听接口
        private OnCodeHisRecyclerviewItemClickListener mOncodeRecyclerviewItemClickListener = null;

        public HisAdapter(Context context, OnCodeHisRecyclerviewItemClickListener mOnRecyclerviewItemClickListener) {
            mContext = context;
            this.mOncodeRecyclerviewItemClickListener = mOnRecyclerviewItemClickListener;
        }

        public void addList(CodeHisResponse.DataBean mlist) {
            hisData.clear();
            hisData.addAll(mlist.getList());
            notifyDataSetChanged();
        }

        //清空数据
        public void cleardata() {
            hisData.clear();
            notifyDataSetChanged();
        }

        @Override
        public int getItemCount() {
            if (hisData == null) {
                return 0;
            } else if (hisData.size() > 5) {
                return 5;
            } else {
                return this.hisData.size();
            }
        }

        public String getItem(int position) {
            return hisData.get(position);
        }

        @Override
        public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
            View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.code_his_list, parent, false);
            view.setOnClickListener(this);
            return new ViewHolder(view);
        }

        @SuppressLint("SetTextI18n")
        @Override
        public void onBindViewHolder(ViewHolder holder, final int position) {
            String item = hisData.get(position);
            if (item != null) {
                holder.tv_code.setText(item);
                holder.itemView.setTag(position);//给view设置tag以作为参数传递到监听回调方法中
            }
        }

        @Override
        public void onClick(View v) {
            //将监听传递给自定义接口
            mOncodeRecyclerviewItemClickListener.onItemClickListener(v, ((int) v.getTag()));
        }

        class ViewHolder extends RecyclerView.ViewHolder {
            TextView tv_code;

            ViewHolder(View itemView) {
                super(itemView);
                tv_code = (TextView) itemView.findViewById(R.id.tv_code);
            }
        }
    }

    public interface OnCodeHisRecyclerviewItemClickListener {
        void onItemClickListener(View v, int position);
    }

适配器item：

Activity调用：

        new HisTask().execute();
        hisAdapter = new HisAdapter(CodeActivity.this, onCodeHisRecyclerviewItemClickListener);
        lv_his.setAdapter(hisAdapter);
