    <p>I have a <code>FragmentActivity</code> that should hold 2 <code>Fragments</code>. Each fragment has it's own layout with a table in it. I need to access the tables from the fragments' layouts from within the <code>FragmentActivity</code> to put some data that I read from an XML file. My problem is that when I use </p> <p><code>tableOrders = (TableLayout)findViewById(R.id.tabel1);</code></p> <p>it returns <code>null</code>. Now, I know that items from layouts can only be accessed before they have been inflated, and I've done that in the FragmentActivity before trying to call <code>findViewById()</code>. Here is the code for what I've tried:</p> <hr> <p>The onCreate of the <code>FragmentHolder.java</code> that is derived from <code>FragmentActivity</code>:</p> <pre><code> private TableLayout tableOrders = null; private TableLayout tableExecutions = null; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_fragment_holder); initialisePaging(); //View orderFragment = (View)findViewById(R.layout.fragment_orders); tableOrders = (TableLayout)/*orderFragment.*/findViewById(R.id.tabel1); //View execFragment = (View)findViewById(R.layout.executions_fragment); tableExecutions = (TableLayout)/*execFragment.*/findViewById(R.id.tabel2); Intent intent = getIntent(); Bundle bundle = intent.getExtras(); if(bundle != null) logedUser = (User) bundle.getSerializable("user"); AssetManager am = getApplicationContext().getAssets(); String xmlContentOrders = XMLfunctions.getXml(am, "ordersData.xml"); populateOrdersTable(xmlContentOrders); String xmlContentExecutions = XMLfunctions.getXml(am, "executionsData.xml"); populateExecutionsTable(xmlContentExecutions); } </code></pre> <hr> <p>The fragment class (don't know if it helps):</p> <pre><code> public class OrdersFragment extends Fragment { @Override public void onActivityCreated(Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = inflater.inflate(R.layout.fragment_orders, container, false); return view; } } </code></pre> <p><hr> The fragment class (don't know if it helps):</p> <pre><code> public class OrdersFragment extends Fragment { @Override public void onActivityCreated(Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); } @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { View view = inflater.inflate(R.layout.fragment_orders, container, false); return view; } } </code></pre> <hr> <p>And the .xml file for the fragment:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" &gt; &lt;TableLayout android:id="@+id/tabel1header" android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="@color/tablebgcolor" &gt; &lt;TableRow &gt; &lt;TextView android:id="@+id/ordersHeader" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_gravity="bottom" android:layout_weight="1" android:text="@string/orders" android:textStyle="bold" /&gt; &lt;/TableRow&gt; &lt;TableRow android:id="@+id/ordersTable" style="@style/HeaderRow" &gt; &lt;TextView android:id="@+id/textSymbol" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" android:text="@string/symbol" style="@style/HeaderText" /&gt; &lt;TextView android:id="@+id/textSide" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" android:text="@string/side" style="@style/HeaderText" /&gt; &lt;TextView android:id="@+id/textPrice" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" android:text="@string/price" style="@style/HeaderText" /&gt; &lt;TextView android:id="@+id/textQuantity" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" android:text="@string/quantity" style="@style/HeaderText"/&gt; &lt;TextView android:id="@+id/textRemaining" android:layout_width="0dp" android:layout_height="wrap_content" android:layout_weight="1" android:text="@string/remanent" style="@style/HeaderText" /&gt; &lt;/TableRow&gt; &lt;/TableLayout&gt; &lt;ScrollView android:layout_width="fill_parent" android:layout_height="0dp" android:layout_weight="1" &gt; &lt;TableLayout android:id="@+id/tabel1" android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="@color/tablebgcolor"&gt; &lt;/TableLayout&gt; &lt;/ScrollView&gt; &lt;/LinearLayout&gt; </code></pre> <p>With that said hope someone has a solution for this (probably it's something easy that I missed).</p> <p><hr> Edit: The code I use to put the Fragments on the FragmentActivity:</p> <pre><code>private void initialisePaging() { OrdersFragment fragmentOne = new OrdersFragment(); ExecutionsFragment fragmentTwo= new ExecutionsFragment(); PagerAdapter pagerAdapter = new PagerAdapter(getSupportFragmentManager()); pagerAdapter.addFragment(fragmentOne); pagerAdapter.addFragment(fragmentTwo); ViewPager viewPager = (ViewPager) super.findViewById(R.id.viewPager); viewPager.setAdapter(pagerAdapter); viewPager.setOffscreenPageLimit(2); viewPager.setCurrentItem(0); } </code></pre>

    1. COHow are you putting the `Fragment`s in your `Activity`? Are you calling the FragmentManager or are you including them in the XML? You can always retrieve the Fragments by code and access its inner members that way.

    2. COI am putting the `Fragments`s in the `Activity` using a `FragmentPagerAdapter` derived class. I'll update the post with the code for that function. And how can I access the fragments inner member through code?

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.

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