来自其他活动的方法不是来自另一个活动的调用

Question

I am trying to Call method from Another Activity but it is not calling. When i use intent it works but when i call method it fails. The method which is in onNotificationPosted() . Here is the code

public class NotificationListener extends NotificationListenerService {

    Context context;
    private DatabaseReference dbref;
    private FirebaseAuth mAuth;

    @Override
    public void onCreate() {
        super.onCreate();
        context = getApplicationContext();
        dbref= FirebaseDatabase.getInstance().getReference();
        mAuth=FirebaseAuth.getInstance();
    }

    @Override
    public void onNotificationPosted(StatusBarNotification sbn) {
        ChatActivity ch=new ChatActivity();
        ch.location();
      //  Intent n=new Intent(NotificationListener.this,ChatActivity.class);
        //startActivity(n);
    }

    @Override
    public void onNotificationRemoved(StatusBarNotification sbn) {
        Log.i("Msg","Notification Removed");
    }
}

The intent which is commented works but the method is not calling. Please help me. Thanks in advance.

使该方法静态，然后像调用它一样

ChatActivity.ch();
