    <p>I have decided for remaking UI of my app by using ViewPagerIndicator and TitlePageIndicator, but I have following problems: </p> <p>1) Fragments that are for each page are not displayed.</p> <p>2) Swipe betwen two pages does not work.</p> <p>I am using ActionBarSherlock as I did with tabs.</p> <p>I have not changed anything in Fragmens since it has workrd fine when I was using tabs and I have written following code:</p> <pre><code>public class CustomFragmentAdapter extends FragmentPagerAdapter { private final String[] TITLES = new String[] { "General", "Companies", "Discounts" }; public final int NUM_TITLES = TITLES.length; public CustomFragmentAdapter(FragmentManager fm) { super(fm); } @Override public Fragment getItem(int position) { Log.v("POSITION", "position: "+position); switch (position) { case 0: return new General(); case 1: return new Companies(); case 2: return new Discounts(); } return null; } @Override public int getCount() { return NUM_TITLES; } @Override public CharSequence getPageTitle(int position) { return TITLES[position % NUM_TITLES].toUpperCase(); } } </code></pre> <p>and</p> <pre><code>mViewPager = (ViewPager)findViewById(R.id.pager); mViewPager.setAdapter(new CustomFragmentAdapter(getSupportFragmentManager())); TitlePageIndicator indicator = (TitlePageIndicator) findViewById(R.id.indicator); indicator.setViewPager(mViewPager); indicator.setCurrentItem(0); </code></pre> <p>and my XML</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/main" android:layout_width="match_parent" android:layout_height="match_parent" &gt; &lt;com.viewpagerindicator.TitlePageIndicator android:id="@+id/indicator" android:layout_height="wrap_content" android:layout_width="match_parent" /&gt; &lt;android.support.v4.view.ViewPager xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/pager" android:layout_width="match_parent" android:layout_height="0dp" android:layout_weight="1" /&gt; </code></pre> <p></p> <p>As I have seen most of the tutorials and examples are quiet similar to my code, but I still can't make it work. I have tried almost everything. It was also not working when I have put there some dummy fragments with just some TextView. I also have tried to remove ViewPagerIndicator and try only ViewPager, but it was not working for me.</p> <p>I am probably missing something, but I can't find it. Thank you very much in advance for your advices.</p>

    1. COThis question has nothing to do with ViewPagerIndicator. This is a ViewPager problem.

    2. COCan you see getItem() being evoked at least once (when the current Fragment is being instantiated)? I mean, the place where you use Log.v

    3. COI can see it evoked three times. After I launch the app it is called twice for position 0 and 1 and then when I tap on item Companies or Discounts it is evoked again for position 2.

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).
