Just for clarity to expand on provided answers In a BaseAdapter you can get the parent class by calling this.getActivity();If you then typecast this to the actual activity class you can then call a function as per @AdilSoomro answer below so you actually end up with something like this

public class MyAdapter extends BaseAdapter<Long> {
    public MyAdapter(Activity activity,
            TreeStateManager<Long> treeStateManager, int numberOfLevels) {
        super(activity, treeStateManager, numberOfLevels);
    }

    @Override
    public void handleItemClick(final View view, final Object id) {
        ((MyActivity) this.activity).someFunction();
    }
}

Then just declare someFunction in MyActivity to do what you want

    protected void someFunction(){
//    Do something here
    }

Inside onClick() Do something like this:

((ParentClass) context).functionToRun();
