Android 清除JsonArray中的数据

JsonArray data=new JsonArray();

  if(data.length（）<1){

    return;

}

final int datasLength = data.length();

//循环清空data中的值，for (int i = 0; i < datasLength; i++) {    Field valuesField = null;    try {        valuesField = JSONArray.class.getDeclaredField("values");    } catch (NoSuchFieldException e) {        // TODO Auto-generated catch block        e.printStackTrace();    }    valuesField.setAccessible(true);    List<Object> values = null;    try {        values = (List<Object>) valuesField.get(data);    } catch (IllegalAccessException e) {        // TODO Auto-generated catch block        e.printStackTrace();    } catch (IllegalArgumentException e) {        // TODO Auto-generated catch block        e.printStackTrace();    }    values.remove(0);//移除data中的值}
