这个json数据格式很简单，不用你想象的那么复杂就能解析；
你需要一个JavaBean对象：
CustomClass.java:

    public class CustomClass {

     private String Name;
     private String Comment;

    public String getName() {
      return Name;
    }
    public void setName(String name) {
      Name = name;
    }
    public String getComment() {
      return Comment;
    }
    public void setComment(String comment) {
      Comment = comment;
    }
    }

MainActivity.java:

    public class MainActivity extends Activity {
    //你的json数据
    String jsonString="     [{\"rowID\":\"1\",\"Name\":\"tqtqwet\",\"Comment\":\"qewrtqwe\"},{\"rowID\":\"2\",\"Name\":\"waf\",\"Comment\":\"agsadga\"},{\"rowID\":\"3\",\"Name\":\"android\",\"Comment\":\"fafdadsf\"},{\"rowID\":\"4\",\"Name\":\"android222\",\"Comment\":\"fasdfas\"},{\"rowID\":\"5\",\"Name\":\"fadfa\",\"Comment\":\"adgasd\"}]";
        @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Type listType = new TypeToken>(){}.getType();
    ArrayList customList = new Gson().fromJson(jsonString, listType);
    }
    }

customList就是你想要的那个带有json数据的集合，你可以通过customList.get(index).getName() or getXXX()得到你想要的值
