According to me, I believe what you are doing here is correct, but still you are not doing the entire flow. Let me explain,

Calling the above method will redirect you to that particular tab. But what you actually have to do is to execute some method in that class. But were are you calling that method.

Consider a Activity with onCreate(),

you could have called that method in your onCreate(). But now when you execute your 

public void switchTabInActivity(int indexTabToSwitchTo) {
        MyTabsActivity ParentActivity;
        ParentActivity = (MyTabsActivity) this.getParent();
        ParentActivity.switchTab(indexTabToSwitchTo);
    }

method, this will call the onResume() of that activity. So my suggestion would be to override the onResume method of your particular activity which has that method..

you can simply create a static method which can be easily call by using ClassName.methodName();

see example, 

public class myAnotherClass
{
      public static void accessFromAnotherClass()
      {
        System.out.println ( "I am accessed publically" );
      }
}


// Now Accessing above class method from another class file

public class myFirstClass
{
      private void myClassMethod()
      {
          myAnotherClass.accessFromAnotherClass();  // called from another class. in your case , another tab.
      }
}
