查询快递中，快递公司数据信息的问题

我将快递公司的相关信息，直接放在了res/raw/companyinfos.json，文件里面，然后在应用启动的时候先创建数据库，然后在选择快递公司画面的时候就读取信息。目前信息不多，但是如果信息再增加的话，会出现进入选择快递公司画面的时候数据加载缓慢，空顿的现象。因此我本来想把所有操作放在MyApplication.java中。

创建数据库

/*** 加载数据流程：第一次安装该应用的时候，就创建数据库 并且解析数据插入数据库* * * SD卡 创建数据库目录* * @throws Exception*/public static void loadDatabase(Context context) throws Exception {// 第一次运行应用程序时，加载数据库到data/data/当前包的名称/database/<db_name>File dir = new File("data/data/" + context.getPackageName()+ "/databases");if (!dir.exists() || !dir.isDirectory()) {dir.mkdir();}File file = new File(dir, "mypackage");// file.delete() ;if (!file.exists()) {// 获得封装.db文件的InputStream对象InputStream is = context.getResources().openRawResource(R.raw.mypackage);FileOutputStream fos = new FileOutputStream("data/data/"+ context.getPackageName() + "/databases/mypackage");byte[] buffer = new byte[7168];int count = 0;// 开始复制.db文件while ((count = is.read(buffer)) > 0) {fos.write(buffer, 0, count);}fos.close();is.close();}}

读取数据到数据库

/*** 解析json数据插入数据库* * @param context* */public static void readData2Db(Context context) {InputStream in = context.getResources().openRawResource(R.raw.companyinfos);try {// 将in读入reader 中BufferedReader br = new BufferedReader(new InputStreamReader(in,"GBK"));StringBuffer buffer = new StringBuffer("");String tem = "";while ((tem = br.readLine()) != null) {buffer.append(tem);}br.close();JSONObject myjson = new JSONObject(buffer.toString());JSONArray jsonarr = myjson.getJSONArray("companyinfos");cls_companyinfo companyinfo = new cls_companyinfo();for (int i = 0; i < jsonarr.length(); i++) {JSONObject njson = jsonarr.getJSONObject(i);String compName = njson.getString("name");String compId = njson.getString("id");String helpinfo = njson.getString("helpinfo");String phoneNumber = njson.getString("phonenumber");companyinfo.info_cd = companyinfo.getMaxIndexNo(Common.dbh);companyinfo.name = compName;companyinfo.id = compId;companyinfo.count = "0";companyinfo.helpInfo = helpinfo;companyinfo.phoneNumber = phoneNumber;companyinfo.addData(Common.dbh);}Common.writeConfig(context, Common.HASLOAD_DATABASE, "1");// 加载数据库完成，写入成功标志位} catch (UnsupportedEncodingException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();} catch (JSONException e) {e.printStackTrace();}}

数据：
