Call Activity's function from OnClick()

I have that code:

public class GeolocationActivity extends ActionBarActivity implements SensorEventListener {
{
    //...

    private void setUpCompass()
    {
        isCompass = true;
        setContentView(R.layout.subactivity_compass);
        //...
    }

    private void setUpMain()
    {
        //...

        btn2 = (Button)findViewById(R.id.geoloc_compass);
        btn2.setOnClickListener(new OnClickListener()
        {
            @Override
            public void onClick(View v) {
                // here I want to call method setUpCompass();
            }
        });
        //...

    }           
}

I want to call setUpCompass() method from onClick() function in setUpMain().

I tried:

Context c = getBaseContext();
((GeolocationActivity)c).setUpCompass();

but I get:

java.lang.ClassCastException: android.app.ContextImpl cannot be cast to com.myname.myapp.GeolocationActivity

What am I doing wrong?

Instead simply use GeolocationActivity.this.

Example:

GeolocationActivity.this.setUpCompass();
