copied!<p>To animate the transition between fragments, or to animate the process of showing or hiding a fragment you use the <code>Fragment Manager</code> to create a <code>Fragment Transaction</code>.</p> <p>Within each Fragment Transaction you can specify in and out animations that will be used for show and hide respectively (or both when replace is used). </p> <p>The following code shows how you would replace a fragment by sliding out one fragment and sliding the other one in it's place.</p> <pre><code>FragmentTransaction ft = getFragmentManager().beginTransaction(); ft.setCustomAnimations(R.anim.slide_in_left, R.anim.slide_out_right); DetailsFragment newFragment = DetailsFragment.newInstance(); ft.replace(R.id.details_fragment_container, newFragment, "detailFragment"); // Start the animated transition. ft.commit(); </code></pre> <p>To achieve the same thing with hiding or showing a fragment you'd simply call <code>ft.show</code> or <code>ft.hide</code>, passing in the Fragment you wish to show or hide respectively.</p> <p>For reference, the XML animation definitions would use the <code>objectAnimator</code> tag. An example of slide_in_left might look something like this:</p> <pre><code><?xml version="1.0" encoding="utf-8"?> <set> <objectAnimator xmlns:android="http://schemas.android.com/apk/res/android" android:propertyName="x" android:valueType="floatType" android:valueFrom="-1280" android:valueTo="0" android:duration="500"/> </set> </code></pre>
