How To Get Values From Accelerometer

my problem is this, i have my main class and a second class that displays the values of the accelerometer on a textview.. however if i call my accelerometer class this is what happens, my application starts with no problems however no buttons work from my main class.. it seems to me that the accelerometer class runs above my main class thats why i have this problem.. what i did is i created a new activity on my manifest and called my accelerometer class from my main class using->

Intent i = new Intent(this, AccelerometerClass.class);
startActivity(i);

Maybe there is a way to just take the values from the accelerometer class,wihout calling the class itself ???? what i mean is take the x,y,z(int) values from accelerometer class and set them on a text from the main class..
