    1、建议修改的代码:

    1 switch (msg.what) {
    2             case SystemConfig.MSG_TYPE_CHANNEL:
    3                 String response = msg.obj.toString();
    4                 //创建JSONObject对象
    5                 try {
    6                         ...
    7                 }
    8             ...
    9  }

    意见:创建JSONObject对象后应该取出所需要的object对象。

    修改后的代码:

     1 switch (msg.what) {
     2             case SystemConfig.MSG_TYPE_CHANNEL:
     3                 String response = msg.obj.toString();
     4                 //创建JSONObject对象,并且取出所需要的object对象
     5                 JSONObject object = null;
     6                 try {
     7                         ...
     8                 }
     9             ...
    10 }

    2、建议修改的代码:

    1  if (showapi_res_code == 0) {
    2                         JSONObject body_object = object.getJSONObject("showapi_res_body");
    3                         String channelId = channelListArray.getJSONObject(0).getString("channelId");
    4                         HttpUtil.httpGetData_Get(SystemConfig.GET_NEWS + "?channelId=" + channelId + "&page=1&needContent=0" + "&needHtml=1", handler, SystemConfig.MSG_TYPE_NEWS);
    5  }

    意见:没有注释,最后一行代码过长不便于观看,还应该创建JSONArray对象

    修改后的代码:

     1  if (showapi_res_code == 0) {
     2                         JSONObject body_object = object.getJSONObject("showapi_res_body");
     3                         //创建JSONArray对象
     4                         JSONArray channelListArray = body_object.getJSONArray("channelList");
     5                         //取出频道列表第一个channelId
     6                         String channelId = channelListArray.getJSONObject(0).getString("channelId");
     7                         HttpUtil.httpGetData_Get(SystemConfig.GET_NEWS + "?channelId
     8                            =" + channelId + "&page
     9                                 =1&needContent=0" + "&needHtml
    10                                     =1", handler, SystemConfig.MSG_TYPE_NEWS);
    11 }

    3、建议修改的代码:

    1 @Override
    2 protected void onCreate(Bundle savedInstanceState) {
    3     super.onCreate(savedInstanceState);
    4     setContentView(R.layout.activity_main);
    5 
    6     lv_datas = (ListView) findViewById(R.id.lv_datas);
    7     myAdapter = new MyAdapter(this);
    8     HttpUtil.httpGetData_Get(SystemConfig.GET_CHANNEL, handler, SystemConfig.MSG_TYPE_CHANNEL);
    9 }

    意见:最后应该绑定Adapter

    修改后的代码:

     1 @Override
     2 protected void onCreate(Bundle savedInstanceState) {
     3     super.onCreate(savedInstanceState);
     4     setContentView(R.layout.activity_main);
     5 
     6     lv_datas = (ListView) findViewById(R.id.lv_datas);
     7     myAdapter = new MyAdapter(this);
     8     HttpUtil.httpGetData_Get(SystemConfig.GET_CHANNEL, handler, SystemConfig.MSG_TYPE_CHANNEL);
     9     //绑定Adapter
    10     lv_datas.setAdapter(myAdapter);
    11 }

    总的来讲,整体代码没有大的错误,只是大部分代码没有注释,而且过于冗长,不利于观看、检查,建议下次将部分重要代码注释,细心编程。
