Question

I am developing an android app which has 3 tabs, created in MainActivity.java. Every tab has its own activity. In those activities I have a method called “Refresh()” to update the listview in that tab.
When the user clicks on a button the method “refreshTab(View v)” is called.

// Tab refreshen
public void refreshTab (View v) {
    Activity MyActivity = this.getCurrentActivity();        
    MyActivity.Refresh();       
}

This is throwing “The Method Refresh() is undefined for the type Activity. However, “MyActivity” is filled with the tab activity.
How would I go about getting this to work?

Answer 1

You need to cast the activity to your type of activity. Right now you are trying to call the Android class activity, which does not have a “Refresh” function.
