如何动态解析JSONArray以上（如文件夹结构）。这是我的代码`类Getdata扩展了AsyncTask {

    @Override
    protected void onPreExecute() {
        super.onPreExecute();

        pDialog.setCancelable(false);
        pDialog.show();
    }

    @Override
    protected Void doInBackground(Void... arg0) {

        if (pref.getString("instraw", null) != null) {
            Log.e("Enter  Not Null>>>", "Not Null");
            spString = pref.getString("instraw", null);
            jsonRes = spString;
            getServerData();
        } else {
            Log.e("Enter Null>>>", "Yes It's Null");
            ServiceHandler handler = new ServiceHandler();
            jsonRes = handler.makeServiceCall(url, ServiceHandler.GET);
            editor.putString("instraw", jsonRes);
            editor.commit();

如果要迭代JSONArray，可以使用for循环执行：

for (int i = 0; i < myArray.length; i++) {
    JSONObject myObject = (JSONObject) myArray.get(i);
    String myString = myObject.getString("myString");
}
