    <p>I'm wondering can I put a viewpager which consist 13images inside a fragment that I created?</p> <p>I've created an app now that consist 7 fragment tabs with each of them showing their own images,webview,and some content in each of their fragments.</p> <p>So now I have a problem,in 1-3 of the tabs I need to put in a slideshow of images parse from json,I was wondering if its possible to use viewpager to show those images and putting it inside the fragment of my tabs.</p> <hr> <h2>UPDATE 12/12/2013</h2> <p>okay,after few days of trying I came up with this code.Unfortunately it doesn't work as I plan.Originally I used asynctask to load the json parsing for the images on a diff project.When I try to combining the json project with my fragment project,I removed the asyctask as I dont know how to implement together.Below is my code and error,<strong>I am aware that the network IO is trying to access main thread</strong> but I dont know how to solve it.Any help would be greatly appreciated.</p> <p><strong>MainActivity</strong></p> <pre><code>public class MainActivity extends FragmentActivity { @Override protected void onCreate(Bundle savedInstanceState) { requestWindowFeature(Window.FEATURE_NO_TITLE); super.onCreate(savedInstanceState); setContentView(R.layout.main); FragmentTabHost tabHost = (FragmentTabHost)findViewById(android.R.id.tabhost); tabHost.setup(this, getSupportFragmentManager(), R.id.realtabcontent); //1 tabHost.addTab(tabHost.newTabSpec("Highlight").setIndicator("Highlight"), AppleFragment.class, null); ... //4 tabHost.addTab(tabHost.newTabSpec("Gallery").setIndicator("Gallery"), GalleryFragment.class, null); </code></pre> <p><strong>GalleryFragment</strong></p> <pre><code>public class GalleryFragment extends Fragment{ private ViewPager mPager; private PagerAdapter mPagerAdapter; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setRetainInstance(true); } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { return inflater.inflate(R.layout.fragment_pager, container,false); } @Override public void onViewCreated(View view, Bundle savedInstanceState) { super.onViewCreated(view, savedInstanceState); mPager = (ViewPager) view.findViewById(R.id.pager); mPagerAdapter = new CustomPagerAdapter(getChildFragmentManager()); mPager.setAdapter(mPagerAdapter); mPager.setCurrentItem(0); } </code></pre> <p><strong>ViewPagerPageFragment</strong></p> <pre><code>public class ViewPagerPageFragment extends Fragment{ @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { return inflater.inflate(R.layout.fragment_page,container,false); } // url to make request private static String url = "http://vina.harvestcamasu.com/vina/xml/image.json"; // JSON Node names static String TAG_IMAGE = "Image"; static String TAG_PICURL = "PicURL"; private String[] images = new String[13]; ProgressDialog mProgressDialog; public Drawable d1,d2,d3,d4,d5,d6,d7,d8,d9,d10,d11,d12,d13; public void onViewCreated(View view, Bundle savedInstanceState) { super.onViewCreated(view, savedInstanceState); view.findViewById(R.id.imageView1); try { // Do something...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
