Question

我正在尝试加载我的Android应用程序的数据，这是几个（float [] [] [] []）数组。我已成功将所提到的数组保存在Jsonarray []中，然后保存到Jsonobject中，最后将Jsonobject保存在文件中，我已经可以在保存的文件中看到我的数据。我面临的问题是，我不知道如何从Jsonarray []中检索我的数组。任何人都可以帮我搞清楚吗？

以下是我保存和重新加载数据的代码：

＆＃13;

func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {

    let view = UIView(frame: CGRect(x: 0, y: 0, width: tableView.frame.size.width, height: 18))
    let label = UILabel(frame: CGRect(x: 20, y: 20, width: 50, height: 50))
    label.text = "TEST TEXT"
    label.textColor = UIColor.whiteColor()

    self.view.addSubview(view)

    return view
}

＆＃13;

这是我保存文件格式的剪辑：

＆＃13;

float[][][][] array1,array2;


//save them with JsonArray
        try {
            JSONObject data_Json = new JSONObject();
            JSONArray[] data_Json_Array = new JSONArray[2];
            data_Json_Array[0] = new JSONArray(array1);
            data_Json_Array[1] = new JSONArray(array2);
            

            for (int i = 0 ; i < 2 ; i++)
                data_Json.put(String.valueOf(i) , data_Json_Array[i]);

            String data_string =  data_Json.toString();
            //card_object is the JSONObject that I want to store.

            File myFile = new File("/sdcard/DATA_Json/myJasonData.txt");
            myFile.createNewFile();
            FileOutputStream fOut = new FileOutputStream(myFile);
            OutputStreamWriter myOutWriter = new OutputStreamWriter(fOut);
            myOutWriter.write(data_string);
            myOutWriter.close();
            fOut.close();
            Log.d("Json Message: " ,"Done writing SD 'myJasonData.txt'");

        }catch (Exception e)
        {
            Log.d("Json Error: " , e.getMessage());
        }



//Reloading arrays from jsonarray
        try {
            JSONObject data_Json = new JSONObject("/sdcard/DATA_Json/myJasonData.txt");
            JSONArray[] data_Json_Array = new JSONArray[2];

            for (int i = 0 ; i < 2 ; i++)
                data_Json_Array[i] = (JSONArray) data_Json.get(String.valueOf(i));

            array1 = data_Json_Array[0].?;    //what should I do here?

        }catch (Exception e)
        {
            Log.d("Json Error: " , e.getMessage());
        }
