(Baidu Map API) V4-2 version positioning function

these days in the Guo Lin teacher's masterpiece, Baidu map This card for a long time, the reason is because Baidu update iteration speed too fast, resulting in the teacher's version of the book has been eliminated and eliminated, but still gave me a lot of inspiration AH. Tonight, I realized the positioning function of Baidu map.

Baidu Map API of what, also do not say more. Official online Introduction is also more detailed, are also Chinese, carefully read down on the line, to, I use the v4-2 version. Feel only 11 o'clock after the work efficiency will be doubled ah, we have not this experience ah, recently want to do a running software, of course, is very simple kind, finished will paste the code and everyone to discuss.

The layout file is not affixed to the code, it is a textview. Yes, I do not know why, I have a Huawei Z87, there is no SM card, but connected to the WiFi, but can not locate the success. But another hammer to go can, if you know, please tell.
