NonActivityClass：

public class NonActivityClass {

    Context context;
    View v;
    public NonActivityClass(Context context, View v) {
        this.context = context;
        this.v = v;
    }

    public void test() {
        Button btn = (Button) v.findViewById(R.id.btn);
        btn.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Toast.makeText(context, "Hello I am inside Non Activity Class",
                        1).show();

            }
        });
    }
}

MainActivity：

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        View v = getLayoutInflater().inflate(R.layout.activity_main, null);
        setContentView(v);
        NonActivityClass nac = new NonActivityClass(MainActivity.this, v);
        nac.test();
    }
}
