私は現在アプリに取り組んでいますが、助けが必要です。アイテムを押すとその説明に移動するリストがある場所に、どうすればそれを持たせることができますか。このアプリで例を見つけることができます https://play.google.com/store/apps/details?id=com.actionbarsherlock.sample.fragments&feature=more_from_developer#?t=W251bGwsMSwxLDEwMiwiY29tLmFjdGlvbmJhcnNoZXJsb2NrLnNhbXBsZS5mcmFnbWVudHMiXQ ..

レイアウトを押したときに得られるものを取得するにはどうすればよいですか。

タブはありますが、リストを取得できません。主なアクティビティ コードは次のとおりです。

public class MainActivity extends FragmentActivity implements ActionBar.TabListener {

/**
 * The {@link android.support.v4.view.PagerAdapter} that will provide fragments for each of the
 * sections. We use a {@link android.support.v4.app.FragmentPagerAdapter} derivative, which will

 * to switch to a {@link android.support.v4.app.FragmentStatePagerAdapter}.
