What is the method on an onOptionsItemSelected menu in WebView for "forward" and "back" in Android?

Question

I am trying to get my webView to move back and forward by calling up the menu. Thus far I have the menu working fine and opening, and the refresh button will refresh the browser. However, I cannot find documentation anywhere about the methods for forward of back. If the default internet browser has them by just pressing the menu key there must be out there. I just can't find them/don't know how to implement them. Any help would be beneficial, thank you.

Here is what I am trying to do:

WebView.Java:

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    super.onCreateOptionsMenu(menu);
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.menu_navigation, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
    case R.id.back_button:

        "???"

    case R.id.forward_button:

        "???"

    case R.id.refresh_button:
            refreshBrowser();
            return true;
          } 
    return false;
   }

The part that I'm missing is marked by the three question marks "???". Let me know if you need more information to get some help, and thanks again.

Answer 1

Use webView.canGoBack and webView.canGoForward to check if there is history data to go back / forward and then load that url.
