Body
<p>I tried to replace a <code>Fragment</code> in <code>FragmentActivity</code> run-time.</p> <h2>fragment_activity.xml</h2> <pre><code><?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/content" android:layout_width="match_parent" android:layout_height="match_parent" /> </code></pre> <h2>MyFragmentActivity.java</h2> <pre><code>public class MyFragmentActivity extends SlidingFragmentActivity { @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.fragment_activity); } // Will be called by AsyncTaskLoader's onLoadFinished. public void selectActiveContent() { // MyFragment's top level is LinearLayout Fragment fragment = new MyFragment(); getSupportFragmentManager().beginTransaction().replace(R.id.content, fragment).commitAllowingStateLoss(); } </code></pre> <p>However, I realize the outcome is not optimized.</p> <p><img src="https://i.stack.imgur.com/pUC87.png" alt="enter image description here"></p> <p>I realize the <code>FrameLayout</code> supplied through my own <code>fragment_activity.xml</code>, is being attached to another parent <code>FrameLayout</code>.</p> <p>Instead of </p> <pre><code>FrameLayout FrameLayout LinearLayout LinearLayout ListView </code></pre> <p>I wish to have</p> <pre><code>FrameLayout LinearLayout LinearLayout ListView </code></pre> <p>May I know how I can achieve so? Is it possible I can have a <code>fragment_activity.xml</code> without a <code>ViewGroup</code> (FrameLayout) ?</p>

Guidance

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.
