ListView getItem onClick() in Tab Fragment

Question

I currently have 9 tabs which all display different items (using this tutorial http://www.androidbegin.com/tutorial/android-custom-listview-texts-and-images-tutorial/). my issue right now is that when I click on the item it doesn't go to my other activity which gives more detail on each item. I'm assuming it's because of the line return rootView at the end, yet I'm not sure what else to do in order to get display the items and the tabs. Here's my code:

public class CreatorFirstScreen extends FragmentActivity {

      SectionsPagerAdapter mSectionsPagerAdapter;

      ViewPager mViewPager;  

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

    // Create the adapter that will return a fragment for each of the three  
    // primary sections of the app.  
    mSectionsPagerAdapter = new SectionsPagerAdapter(getSupportFragmentManager());  

    // Set up the ViewPager with the sections adapter.  
    mViewPager = (ViewPager) findViewById(R.id.pager);  
    mViewPager.setAdapter(mSectionsPagerAdapter);  

    PagerTabStrip strip = (PagerTabStrip)findViewById(R.id.tabstrip);
    strip.setTabIndicatorColor(0xFFFF);

}    

/** 
 * A {@link FragmentPagerAdapter} that returns a fragment corresponding to 
 * one of the sections/tabs/pages. 
 */  
public class SectionsPagerAdapter extends FragmentPagerAdapter {  

    public SectionsPagerAdapter(FragmentManager fm) {  
        super(fm);  
    }  

    @Override  
    public Fragment getItem(int position) {  
        // getItem is called to instantiate the fragment for the given page.  
        // Return a DummySectionFragment (defined as a static inner class  
        // below) with the page number as its lone argument.  
        Fragment fragment = new DummySectionFragment();  
        Bundle args = new Bundle();  
        args.putInt(DummySectionFragment.ARG_SECTION_NUMBER, position + 1);  
        fragment.setArguments(args);  
        return fragment;  
    }  

    @Override  
    public int getCount() {  
        // Show 9 total pages.  
        return 9;  
    }  

    @Override  
    public CharSequence getPageTitle(int position) {  
        Locale l = Locale.getDefault();  
        switch (position) {  
        case 0:  
            return getString(R.string.title_section1).toUpperCase(l);  
        case 1:  
            return getString(R.string.title_section2).toUpperCase(l);  
        case 2:  
            return getString(R.string.title_section3).toUpperCase(l);  
        case 3:  
            return getString(R.string.title_section4).toUpperCase(l); 
        case 4:  
            return getString(R.string.title_section5).toUpperCase(l); 
        case 5:  
            return getString(R.string.title_section6).toUpperCase(l); 
        case 6:  
            return getString(R.string.title_section7).toUpperCase(l); 
        case 7:  
            return getString(R.string.title_section8).toUpperCase(l); 
        case 8: 
            return getString(R.string.title_section9).toUpperCase(l);
        }  
        return null;  
    }  
}

Answer 1

I believe the OnItemClickListener doesn't get attached to the mainListView because its root view hasn't yet been created. For it to work, try moving the related code (everything after the switch statement) to the onViewCreated method which fires right after onCreateView returns the rootView.

A CheckBox that's present in this ListView's row layout will steal its parent view's focus so the OnItemClickListener's onItemClick method won't get called. To overcome this, add android:focusable="false" and android:focusableInTouchMode="false" parameters to the CheckBox.
