android - Android onOptionsItemSelected

Question

私はこのコードについて混乱しています.6つのメニュー項目があり、それぞれがWebビューに別のWebページをロードしたいのですが、項目3が選択されたときにどこでこれを行うことができるかわかりません.誰か助けてもらえますか?

@Override
    public boolean onOptionsItemSelected(MenuItem item) {

        // call ActionBarDrawerToggle.onOptionsItemSelected(), if it returns true
        // then it has handled the app icon touch event

            if (actionBarDrawerToggle.onOptionsItemSelected(item)) {
        return true;
    }
        return super.onOptionsItemSelected(item);
    }

そして、私は助けが必要なだけなので、これについて私に虐待を与えないでください:/

私のstrings.xml

<string-array name="items">
    <item>Item 1</item>
    <item>Item 2</item>
    <item>Item 3</item>
    <item>Item 4</item>
    <item>Item 5</item>
    <item>Item 6</item>
</string-array>

そのため、別の項目をクリックするたびに mWebView.loadUrl(""); が実行されます。
