copied!<p>I know this has a few answers, but maybe this will help someone. I have used a relatively simple solution when I needed to get a <code>Fragment</code> from my <code>ViewPager</code>. In your <code>Activity</code> or <code>Fragment</code> holding the <code>ViewPager</code>, you can use this code to cycle through every <code>Fragment</code> it holds. </p> <pre><code>FragmentPagerAdapter fragmentPagerAdapter = (FragmentPagerAdapter) mViewPager.getAdapter(); for(int i = 0; i < fragmentPagerAdapter.getCount(); i++) { Fragment viewPagerFragment = fragmentPagerAdapter.getItem(i); if(viewPagerFragment != null) { // Do something with your Fragment // Check viewPagerFragment.isResumed() if you intend on interacting with any views. } } </code></pre> <ul> <li><p>If you know the position of your <code>Fragment</code> in the <code>ViewPager</code>, you can just call <code>getItem(knownPosition)</code>.</p></li> <li><p>If you don't know the position of your <code>Fragment</code> in the <code>ViewPager</code>, you can have your children <code>Fragments</code> implement an interface with a method like <code>getUniqueId()</code>, and use that to differentiate them. Or you can cycle through all <code>Fragments</code> and check the class type, such as <code>if(viewPagerFragment instanceof FragmentClassYouWant)</code></p></li> </ul> <p><strong>!!! EDIT !!!</strong></p> <p>I have discovered that <code>getItem</code> only gets called by a <code>FragmentPagerAdapter</code> when each <code>Fragment</code> needs to be created the <strong>first time</strong>, after that, it appears the the <code>Fragments</code> are recycled using the <code>FragmentManager</code>. This way, many implementations of <code>FragmentPagerAdapter</code> create <strong>new</strong> <code>Fragment</code>s in <code>getItem</code>. Using my above method, this means we will create new <code>Fragment</code>s each time <code>getItem</code> is called as we go through all the items in the <code>FragmentPagerAdapter</code>. Due to this, I have found a better approach, using the <code>FragmentManager</code> to get each <code>Fragment</code> instead (using the accepted answer). This is a more complete solution, and has been working well for me.</p> <pre><code>FragmentPagerAdapter fragmentPagerAdapter = (FragmentPagerAdapter) mViewPager.getAdapter(); for(int i = 0; i < fragmentPagerAdapter.getCount(); i++) { String name = makeFragmentName(mViewPager.getId(), i); Fragment viewPagerFragment = getChildFragmentManager().findFragmentByTag(name); // OR Fragment viewPagerFragment = getFragmentManager().findFragmentByTag(name); if(viewPagerFragment != null) { // Do something with your Fragment if (viewPagerFragment.isResumed()) { // Interact with any views/data that must be alive } else { // Flag something for update later, when this viewPagerFragment // returns to onResume } } } </code></pre> <p>And you will need this method.</p> <pre><code>private static String makeFragmentName(int viewId, int position) { return "android:switcher:" + viewId + ":" + position; } </code></pre>
