Android 将值从ActionBarActivity发送到ListFragment

我有一个ActionBarActivity，它实现ActionBar.TabListener，如下所示

public class MainActivity extends ActionBarActivity implements
        ActionBar.TabListener {
viewPager = (ViewPager) findViewById(R.id.pager);
    actionBar = getSupportActionBar();
    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);

    mAdapter = new TabsPagerAdapter(getSupportFragmentManager());
    viewPager.setAdapter(mAdapter);

    Tab tab1 = actionBar.newTab();
    tab1.setText("Home");
    tab1.setTabListener(this);
    actionBar.addTab(tab1);

//我还有其他几个标签 }

我有一些类似下面的列表片段

public class Home extends ListFragment {
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.home, container, false);
    return rootView;
}
}

我需要根据特定条件将特定键或值从MainActivity发送到ListFragment。我如何做到这一点？我如何从ListFragment接收这些值？我也在使用ViewPager。因此，我将无法传递静态片段名称。

您可以这样做-

主要活动类-

主片段类-

public class Home extends ListFragment {
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    View rootView = inflater.inflate(R.layout.home, container, false);
    return rootView;
}
}

public class MainActivity extends ActionBarActivity implements
    ActionBar.TabListener {

    private String myString = "hello";

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_my);
        ...
    }

    public String getMyData() {
        return myString;
    }
}

public class Home extends ListFragment {

    @Override
    public View onCreateView(LayoutInflater inflater, 
    ViewGroup container, Bundle savedInstanceState) {
         View rootView = inflater.inflate(R.layout.home, container, false);

        MainActivity activity = (MainActivity) getActivity();
        String myDataFromActivity = activity.getMyData();
        return rootView;
    }
}
