Android application development issues Baidu map location, novice seeking Great God help look

Baidu map android application positioning

I am graduating students, work in the company, because the development needs, I went to study under the open platform Baidu Baidu Maps Map Android SDK location positioning function, and then I wrote a map to show your current location plus locate code. Why is my program, which is indeed the position of the positioning of the Pacific, rather than my current position, ah, then God help us to see where to find the big problem, the way to help me think about how can locate the point display "longitude latitude" and If I move a distance I could see the start position to the stop position trajectory. I am a beginner, it is best to explain the point code? Thank you

Reply:
Position offset is too large, then consider whether or not to engage in bad latitude and longitude
Reply:
I considered this reason, did not write bad ah

Reply:
Click to get MyLocationListener inside debug precision latitude, see if it is the correct value, whether the positioning, whether to get into the accuracy of latitude
