Help with Android dynamic fragments

0 posts in this topic

edit: i'm editing my post to better explain my problem.

 

I have an android application using swipe tabs to navigate between fragments. I have 2 fragments defined in xml file and 1 main activity. Whenever I run my application I'm getting the tabs to show up properly with the correct names "Administration", "Scan", "About"... but the page is blank. When I step through my debugger to check the return value of onCreateView (in my FragmentPagerAdapter code below) it appears to be returning correct value... I can't figure out why I keep getting a blank screen.

 

Here is my activity_main.xml

    <android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android"  
    xmlns:tools="http://schemas.android.com/tools"  
    android:id="@+id/pager"  
    android:layout_width="match_parent"  
    android:layout_height="match_parent"  
    tools:context="com.atd.giftmonster.MainActivity" />  

Here is my MainActivity.java

public class MainActivity extends ActionBarActivity implements ActionBar.TabListener {  
      
    ViewPager mViewPager;  
    DFragmentManager mFragmentManager;  
      
    private static EditText textEmail;  
    private static EditText textPw;  
      
    @Override  
    protected void onCreate(Bundle savedInstanceState) {  
        super.onCreate(savedInstanceState);  
        setContentView(R.layout.activity_main);  
      
        List<String> titles = new ArrayList<String>();  
        titles.add("administrator");  
        titles.add("scan");  
        titles.add("about");  
      
        List<Integer> layoutids = new ArrayList<Integer>();  
        layoutids.add(R.layout.fragment_admin);  
        layoutids.add(R.layout.fragment_scan);  
        layoutids.add(R.layout.fragment_scan);  
      
        // Set up the action bar.  
        final ActionBar actionBar = getSupportActionBar();  
        actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);  
      
        mFragmentManager = new DFragmentManager(getSupportFragmentManager(), layoutids, titles);  
      
        // Set up the ViewPager with the sections adapter.  
        mViewPager = (ViewPager) findViewById(R.id.pager);  
        mViewPager.setAdapter(mFragmentManager);  
      
        // When swiping between different sections, select the corresponding  
        // tab. We can also use ActionBar.Tab#select() to do this if we have  
        // a reference to the Tab.  
        mViewPager.setOnPageChangeListener(new ViewPager.SimpleOnPageChangeListener() {  
            @Override  
            public void onPageSelected(int position) {  
                actionBar.setSelectedNavigationItem(position);  
            }  
        });  
      
        // For each of the sections in the app, add a tab to the action bar.  
        for (int i = 0; i < mFragmentManager.getCount(); i++) {  
            actionBar.addTab(  
                    actionBar.newTab()  
                            .setText(mFragmentManager.getPageTitle(i))  
                            .setTabListener(this));  
        }  
    }  

Here is my FragmentPagerAdapter w/ static fragment class

    public class DFragmentManager extends FragmentPagerAdapter {  
      
    List<String> mTitle;  
    List<Integer> mLayoutID;  
    List<Fragment> mFragments;  
    FragmentManager mFragmentManager;  
      
    public DFragmentManager(FragmentManager fm, List<Integer> layoutIDs, List<String> layoutTitles)  
    {  
        super(fm);  
        mFragments = new ArrayList<Fragment>();  
      
        mLayoutID = layoutIDs;  
        mFragmentManager = fm;  
        mTitle = layoutTitles;  
      
        int size = mLayoutID.size();  
      
        for (int i = 0; i < size; i++)  
        {  
      
            mFragments.add(DFragment.newInstance(mLayoutID.get(i)));  
        }  
    }  
      
    @Override  
    public Fragment getItem(int position)  
    {  
        return mFragments.get(position);  
    }  
      
    @Override  
    public int getCount()  
    {  
        return mFragments.size();  
    }  
      
    @Override  
    public CharSequence getPageTitle(int position) {  
        //return (CharSequence)new String("ss");  
        //return (CharSequence) mFragments.get(position).getTitle();  
        return (CharSequence) mTitle.get(position);  
    }  
      
    public Fragment getFragment(int position)  
    {  
        return mFragments.get(position);  
    }  
      
    public static class DFragment extends Fragment  
    {  
        private View mView;  
        private static final String ARG_LAYOUT_ID = "layout_id";  
      
        public static final DFragment newInstance(int layoutID)  
        {  
            DFragment fragment = new DFragment();  
            Bundle bundle = new Bundle();  
            bundle.putInt(ARG_LAYOUT_ID, layoutID);  
            fragment.setArguments(bundle);  
            return fragment;  
        }  
      
        @Override  
        public View onCreateView(LayoutInflater inflater, ViewGroup group, Bundle bundle)  
        {  
            int resourceID = getArguments().getInt(ARG_LAYOUT_ID);  
            mView = inflater.inflate(resourceID, group, false);  
            return mView;  
        }  
      
        public View getView()  
        {  
            return mView;  
        }  
    }
