POGet the current fragment object
Body
 

Note that there are some explanatory texts on larger screens.

plurals
  1. POGet the current fragment object
    text
    copied!<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>
