具体的fastjson我就不再次介绍了不懂得看我上一篇博客http://blog.csdn.net/kluing/article/details/40982143

先看一下解析的文本内容：

{"id": "chart1","series": [{"id": "bar1","type": "bar","groupId": "0","horizonal": false,"percentage": true,"stackType": "stack"}, {"id": "bar2","type": "bar","groupId": "0","horizonal": false,"percentage": true,"stackType": "stack"}, {"id": "bar3","type": "bar","groupId": "1","horizonal": false,"percentage": true,"stackType": "stack"}, {"id": "line1","type": "line","yAxis": "rightAxis"}],"tools": [{"type": "categoryTool"}]}

下面介绍如何解析assets的json数据文件

先写一个解析的类，具体什么作用我都用log来解释了，不懂得可以看下最后的log图与解析的内容比对。

<span style="font-size:18px;">public class JsonTools {    public static JSONObject jsonData(Context context,String fileName){//filename assets目录下的json文件名        JSONObject jsonDate=null;        try {            InputStreamReader inputStreamReader=new InputStreamReader(context.getAssets().open(fileName),"UTF-8");            BufferedReader bufferedReader=new BufferedReader(inputStreamReader);            String line;            StringBuilder stringBuilder=new StringBuilder();            while ((line=bufferedReader.readLine())!=null){                stringBuilder.append(line);            }            bufferedReader.close();            inputStreamReader.close();            jsonDate=JSON.parseObject(stringBuilder.toString());//得到JSONobject对象            Log.e("jsonDate","=="+jsonDate);            String idArray=jsonDate.getString("id");//得到id的内容            Log.e("idArray","=="+idArray);            JSONArray  seriesArray=jsonDate.getJSONArray("series");得到series节点，不懂得看Log打印就清楚了            Log.e("seriesArray","="+seriesArray);            List<Series> listSeries=JSON.parseArray(seriesArray.toString(),Series.class);            for(Series series:listSeries){                Log.e("series.getId","="+series.getId());                Log.e("series.getType","="+series.getType());                Log.e("series.getGroupId","="+series.getGroupId());                Log.e("series.getHorizonal","="+series.getHorizonal());                Log.e("series.getPercentage","="+series.getPercentage());                Log.e("series.getStackType","="+series.getStackType());                Log.e("series.getyAxis","="+series.getYAxis());            }            JSONArray  toolsArray=jsonDate.getJSONArray("tools");得到tools节点            List<Tools> listTools=JSON.parseArray(toolsArray.toString(),Tools.class);            for(Tools tools:listTools){                Log.e("tools.getType","="+tools.getType());            }        } catch (IOException e) {            e.printStackTrace();        }        return jsonDate;    }}</span>

然后写3个工具类：

<span style="font-size:18px;">public class GroupData {    private String id;    private List<Series> seriesList=new ArrayList<Series>();    private List<Tools> toolsList=new ArrayList<Tools>();    public String getId() {        return id;    }    public void setId(String id) {        this.id = id;    }    public List<Series> getSeriesList() {        return seriesList;    }    public void setSeriesList(List<Series> seriesList) {        this.seriesList = seriesList;    }    public List<Tools> getToolsList() {        return toolsList;    }    public void setToolsList(List<Tools> toolsList) {        this.toolsList = toolsList;    }}</span>

<span style="font-size:18px;">public class Series {    private String id;    private String type;    private String groupId;    private String horizonal;    private String percentage;    private String stackType;    private String yAxis;    public String getYAxis() {        return yAxis;    }    public void setYAxis(String yAxis) {        this.yAxis = yAxis;    }    public String getStackType() {        return stackType;    }    public void setStackType(String stackType) {        this.stackType = stackType;    }    public String getPercentage() {        return percentage;    }    public void setPercentage(String percentage) {        this.percentage = percentage;    }    public String getHorizonal() {        return horizonal;    }    public void setHorizonal(String horizonal) {        this.horizonal = horizonal;    }    public String getGroupId() {        return groupId;    }    public void setGroupId(String groupId) {        this.groupId = groupId;    }    public String getType() {        return type;    }    public void setType(String type) {        this.type = type;    }    public String getId() {        return id;    }    public void setId(String id) {        this.id = id;    }}</span>

<span style="font-size:18px;">public class Tools {    private String type;    public String getType() {        return type;    }    public void setType(String type) {        this.type = type;    }}</span>

这里工具类，具体怎么写这个是需要根据我们的json数据的格式来写的。还有就是用的时候不要忘了导入有关fastjson的jar。

最后看一下打印的Log，版面问题就只截了一部分的图。希望对大家有帮助！！
