title: Get the current fragment object
body: <p>In my <code>main.xml</code> I have</p>
  
  <pre><code>  &lt;FrameLayout
          android:id="@+id/frameTitle"
          android:padding="5dp"
          android:layout_height="wrap_content"
          android:layout_width="fill_parent"
          android:background="@drawable/title_bg"&gt;
              &lt;fragment
                android:name="com.fragment.TitleFragment"
                android:id="@+id/fragmentTag"
                android:layout_width="fill_parent"
                android:layout_height="wrap_content" /&gt;
  
    &lt;/FrameLayout&gt;
  </code></pre>
  
  <p>And I'm setting fragment object like this </p>
  
  <pre><code>FragmentManager fragmentManager = activity.getSupportFragmentManager();
  FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
  Fragment newFragment = new FragmentType1();
  fragmentTransaction.replace(R.id.frameTitle, casinodetailFragment, "fragmentTag");
  
  // fragmentTransaction.addToBackStack(null);
  fragmentTransaction.commit();
  </code></pre>
  
  <p>It is setting different types of Fragment objects (<code>FragmentType2,FragmentType3,...</code>) at different time. Now at some point of time I need to identify which object is currently there.</p>
  
  <p>In <strong>short</strong> I need to do something like this:</p>
  
  <pre><code>Fragment currentFragment = //what is the way to get current fragment object in FrameLayout R.id.frameTitle
  </code></pre>
  
  <p>I tried the following  </p>
  
  <pre><code>TitleFragment titleFragmentById = (TitleFragment) fragmentManager.findFragmentById(R.id.frameTitle);
  </code></pre>
  
  <p>and </p>
  
  <pre><code>    TitleFragment titleFragmentByTag = (TitleFragment) fragmentManager.findFragmentByTag("fragmentTag");
  </code></pre>
  
  <p>But <strong>both the objects (titleFragmentById and titleFragmentByTag  ) are <code>null</code></strong><br>
  Did I miss something?<br>
  I'm using <code>Compatibility Package, r3</code> and developing for <code>API level 7</code>.</p>
  
  <p><code>findFragmentById()</code> and <code>findFragmentByTag()</code> will work if we have set fragment using <code>fragmentTransaction.replace</code> or <code>fragmentTransaction.add</code>, but will <code>return null</code> if we have set the object at xml (like what I have done in my <code>main.xml</code>). I think I'm missing something in my XML files.</p>
