Android stock data through the day K get week K data algorithm source code

The current data is obtained from the Sina interface, http://biz.finance.sina.com.cn/stock/flash_hq/kline_data.php?symbol=sh600000&end_date= 20141120&begin_date=20120101

The return data is in XML format:

1 <?xml version= "1.0" encoding= "UTF-8"?>2 <control>3     <content d= " 2012-01-04 "o=" 8.540 "h=" 8.560 "c=" 8.410 "l=" 8.390 "v=" 342014 "bl=" "/>4     <content d=" 2012-01-05 "o=" 8.470 "h=" 8.820 "c=" 8.650 "l=" 8.470 "v=" 1321162 "bl=" "/>5     <content d=" 2012-01-06 "o=" 8.630 "h=" 8.780 "c=" 8.710 "l=" 8.620 "v=" 617787 "bl=" "/>6     <content d=" 2012-01-09 "o=" 8.720 "h=" 8.990 "c=" 8.950 "L=" 8.680 "v=" 801362 "bl=" "/>78 </control>

By using the above interface, you can obtain the data of the day K and encapsulate it to a list collection for saving.

The following code is the data collection of the week K by the data collection of day K.

The operation efficiency of the above code can be optimized again.
