using threads in class

hii i am developing an app in which i m getting locations and speed. now when the user in speed , i m showing a screen in front of user on which user has 2 buttons. and doing same in a zone which we make restricted. user has to send sms to parent if he is in speed or zone. but i m getting a problem that as user got speed my screen is not coming, phone got hanged and app is in App not responding mode. i apply threading for this also but didn't get succeed , please check my code and guide me is there is anything goes wrong.if the first screen is coming than on click of button it is going in same situation as above.
