Android标签活动按排序添加新片段

Question

最初我的想法是创建一个使用选项卡式活动的子项列表。 1-父母有一个或多个孩子。 2-使用排球我希望使用选项卡式活动将逻辑传递给manege为每个孩子自己创建一个新的片段。

我尝试了，因为你可以在下面看到我的活动，之后你会看到我的适配器：

let locationManager1: CLLocationManager // your location manager
    func addBoundry(loc: CLLocation)
    {
        if let loc: CLLocation! = locationManager1.location {
        let center: CLLocationCoordinate2D = loc!.coordinate
        let lat: CLLocationDegrees = center.latitude
        let long: CLLocationDegrees = center.longitude
        var points = [CLLocationCoordinate2DMake(lat,long),CLLocationCoordinate2DMake(lat,long),CLLocationCoordinate2DMake(lat,long),CLLocationCoordinate2DMake(lat,long)]
        let polygon = MKPolygon(coordinates: &points, count: points.count)

        mapView.addOverlay(polygon)

        } else {
            print("no location...")
        }
    }

}

private ViewPager mViewPager = null;
private ChildAdapter pagerAdapter = null;

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

    // Set up the ViewPager with the sections adapter.
    pagerAdapter = new ChildAdapter();
    mViewPager = (ViewPager) findViewById(R.id.view_pager);
    mViewPager.setAdapter(pagerAdapter);

    LayoutInflater inflater = context.getLayoutInflater();
    FrameLayout v0 = (FrameLayout) inflater.inflate(R.layout.fragment_profile, null);
    pagerAdapter.addView(v0, 0);

}

//-----------------------------------------------------------------------------
// Here's what the app should do to add a view to the ViewPager.
public void addView(View newPage) {
    int pageIndex = pagerAdapter.addView(newPage);
    // You might want to make "newPage" the currently displayed page:
    mViewPager.setCurrentItem(pageIndex, true);
}

//-----------------------------------------------------------------------------
// Here's what the app should do to remove a view from the ViewPager.
public void removeView(View defunctPage) {
    int pageIndex = pagerAdapter.removeView(mViewPager, defunctPage);
    // You might want to choose what page to display, if the current page was "defunctPage".
    if (pageIndex == pagerAdapter.getCount())
        pageIndex--;
    mViewPager.setCurrentItem(pageIndex);
}

//-----------------------------------------------------------------------------
// Here's what the app should do to get the currently displayed page.
public View getCurrentPage() {
    return pagerAdapter.getView(mViewPager.getCurrentItem());
}

//-----------------------------------------------------------------------------
// Here's what the app should do to set the currently displayed page.  "pageToShow" must
// currently be in the adapter, or this will crash.
public void setCurrentPage(View pageToShow) {
    mViewPager.setCurrentItem(pagerAdapter.getItemPosition(pageToShow), true);
}
