    <p>As the title suggest.<br> I've downloaded <code>Fragment</code> code from here, <a href="http://developer.android.com/shareables/training/FragmentBasics.zip" rel="nofollow noreferrer">http://developer.android.com/shareables/training/FragmentBasics.zip</a>.<br> It is Fragment example from <strong>Android Official Developer site</strong>. <a href="http://developer.android.com/training/basics/fragments/fragment-ui.html" rel="nofollow noreferrer">http://developer.android.com/training/basics/fragments/fragment-ui.html</a></p> <p>This is the <code>MainActivity.java</code>'s <code>onCreate()</code>:</p> <pre><code>/** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.news_articles); // Check whether the activity is using the layout version with // the fragment_container FrameLayout. If so, we must add the first fragment if (findViewById(R.id.fragment_container) != null) { // However, if we're being restored from a previous state, // then we don't need to do anything and should return or else // we could end up with overlapping fragments. if (savedInstanceState != null) { return; } // Create an instance of ExampleFragment HeadlinesFragment fragment = new HeadlinesFragment(); // In case this activity was started with special instructions from an Intent, // pass the Intent's extras to the fragment as arguments //fragment.setArguments(getIntent().getExtras()); Bundle args= new Bundle(); args.putString("category", "clothes"); args.putString("item", "shirts"); fragment.setArguments(args); // Add the fragment to the 'fragment_container' FrameLayout getSupportFragmentManager().beginTransaction() .replace(R.id.fragment_container, fragment).commit(); } } </code></pre> <p><strong>And <code>HeadlinesFragment.java</code>'s <code>onCreate()</code>:</strong></p> <pre><code>@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // We need to use a different list item layout for devices older than Honeycomb int layout = Build.VERSION.SDK_INT &gt;= Build.VERSION_CODES.HONEYCOMB ? android.R.layout.simple_list_item_activated_1 : android.R.layout.simple_list_item_1; Bundle args = getArguments(); if (args == null) { Toast.makeText(getActivity(), "arguments is null " , Toast.LENGTH_LONG).show(); } else { Toast.makeText(getActivity(), "text " + args , Toast.LENGTH_LONG).show(); } // Create an array adapter for the list view, using the Ipsum headlines array setListAdapter(new ArrayAdapter&lt;String&gt;(getActivity(), layout, Ipsum.Headlines)); } </code></pre> <p>I've read several QA here, like this one <a href="https://stackoverflow.com/questions/14970790/fragment-getarguments-returns-null">Fragment getArguments() returns null</a>, and many other that related to <code>setArguments()</code> and <code>getArguments()</code>, but still I'm stuck.</p> <p>And I've moved the <strong><code>Bundle</code></strong> and <strong><code>Toast</code></strong> code to <code>onAttach()</code> and to <code>onCreateView()</code> with no avail. What wrong with the my code? I think I'm missing something, but dunno what is it.<br> Please Help! Thanks.</p> <p><strong>Edit</strong>:<br> I'll state my intention more clearly. In FragmentBasic that I downloaded, there's MainActivity.java, HeadlinesFragment.java, and ArticlesFragment.java. The 'communication' from MainActivity.java to ArticlesFragment.java is not the problem here. What I want is to send data from MainActivity.java to HeadlinesFragment.java. Their connection's like this:</p> <pre><code>-------------------------------------- | MainActivity &lt;-&gt; HeadlinesFragment | | | | | |&gt;&gt; ArticlesFragment | -------------------------------------- </code></pre> <p>And <code>HeadlinesFragment</code> is running at Runtime. </p> <p>*These code works, when using Android gadget with &lt; 600px width. But doesn't work when using on tablet ( >= 600px), As proved by @Tesla1984 below. But what I want is same result either on gadget &lt; 600px and on gadget > 600px.</p>

    2. CO@tesla1984: on what part you insert your code? in HeadlinesFragment.java or ArticlesFragment.java? Cause Wherever I put the `getArguments()` in HeadlinesFragment.java, I get null. Thanks.

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).
