런타임에 항목을 만들고 싶습니다. 설정하고 싶은 FragmentActivity에 전역 변수가 있으며 onActivityCreated() 메서드의 단편에서이 변수를 사용합니다. 그러나 분명히 그들은 그들이 생성 될 때 null이며, 단편이 생성 될 때까지 데이터를 사용해야 할 필요가 없습니다. 누구든지이 일을하는 좋은 방법을 찾았습니까? 나는 현재 이것을하기 위해 ActionBarSherlock을 사용하고있다.ActionBarSherlock을 사용하여 활동을 만든 후 조각을 새로 고치는 방법
Fragment는 새로 고칠 수 있지만 Activity는 새로 고침 할 수 없으면 모든 항목이 다시 null이됩니다.
제발 아무도 도와 줄 수 없어요. 미리 감사드립니다.
FragmentActivity 코드 :
public class SlidingTabsActivity extends SherlockFragmentActivity
{
/* Sliding tabs */
private ViewPager viewPager;
private TabsAdapter tabsAdapter;
private ActionBar actionBarTabs;
/* Custom tab view */
private LayoutInflater customTabViewLayoutInflater;
private View customTabView;
/* Layer interfaces */
private CommsLayerInterface commsLayerInterface;
private DeviceLayerInterface deviceLayerInterface;
private PopupFirmware popupFirmware; // Popup firmware class instance
/* Data set information */
private DeviceInfo deviceInfo;
private Pages pages;
private Page page1;
private Page page2;
private Page page3;
@Override
protected void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
viewPager = new ViewPager(this);
viewPager.setId(R.id.pager);
setContentView(viewPager);
tabsAdapter = new TabsAdapter(this, viewPager); // Declares the tabs adapter class with the view pager view
popupFirmware = new PopupFirmware(this); // Declaring popup firmware class
commsLayerInterface = new CommsLayerInterface();
deviceLayerInterface = new DeviceLayerInterface(this);
deviceLayerInterface.setCommsLayerInterface(commsLayerInterface);
/* Custom tab view instances */
customTabViewLayoutInflater = (LayoutInflater) this.getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
customTabView = customTabViewLayoutInflater.inflate(R.layout.tabs_spinner, null);
/* Custom view functions */
TabCustomViewFunctions.createSpinnerList(this, customTabView, deviceLayerInterface);
TabCustomViewFunctions.createNewFile(this, customTabView, deviceLayerInterface);
TabCustomViewFunctions.saveFile(customTabView, deviceLayerInterface);
/* Set up pages and device info */
deviceInfo = deviceLayerInterface.getDeviceInfo();
pages = deviceLayerInterface.getPages();
setUpPages(pages);
/* Action Bar */
actionBarTabs = getSupportActionBar();
actionBarTabs.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
actionBarTabs.setCustomView(customTabView);
actionBarTabs.setDisplayShowCustomEnabled(true);
/* Adds fragments to the tabs adapter */
tabsAdapter.addTab(actionBarTabs.newTab().setText("FRAG1"), Fragment_1.class, null);
tabsAdapter.addTab(actionBarTabs.newTab().setText("FRAG2"), Fragment_2.class, null);
tabsAdapter.addTab(actionBarTabs.newTab().setText("FRAG3"), Fragment_3.class, null);
}
}
조각 코드 : 인터페이스를 사용하여
public class Fragment_1 extends SherlockFragment
{
private View view;
private CustomLayout layout; // Container view layout class instance
private SlidingTabsActivity slidingTabsActivity;
private DeviceInfo deviceInfo;
private Page page;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
{
view = inflater.inflate(R.layout.fragment_custom, container, false);
return view;
}
@Override
public void onActivityCreated(Bundle savedInstanceState)
{
super.onActivityCreated(savedInstanceState);
/* Creates the new views from the layout class */
slidingTabsActivity = (SlidingTabsActivity) getSherlockActivity();
deviceInfo = slidingTabsActivity.getDeviceInfo();
page = slidingTabsActivity.getPage1();
if(page != null & deviceInfo != null)
{
layout = new CustomLayout(slidingTabsActivity);
layout.setDeviceInfo(deviceInfo);
layout.setPage(page);
layout.createView();
System.out.println("Page and device info are NOT null!");
}
else
{
System.out.println("Page and device info are null!");
}
}
}
