I found an answer.

class MyScreen extends Component {



  static navigationOptions = () => {

    return {

      tabBarOnPress({ navigation, defaultHandler }) {



        navigation.state.params.onTabFocus('tab_name');



        defaultHandler();

      }

    };

  };



  componentDidMount() {

    this.props.navigation.setParams({

      onTabFocus: this.getCurrentTab

    });

  }



  getCurrentTab = (tabName) => {

    console.log("current tab >>>>>>", tabName);

  };

}

/////////// Second solution ///////////////

Can use NavigationEvents Component to subscribe to these navigation events.

onWillFocus : before focusing a tab

onDidFocus : after focusing a tab

onWillBlur : before losing focus on a tab

onDidBlur : after losing focus on a tab
