Android: Replaced Fragment Is Still Visible

On Android, if you replace a fragment using FragmentTransaction.replace, the old fragment could still be seen. This is most often caused by not setting the background color of the fragment.

Below is a screenshot of the main fragment.


When the fragment is replaced, both fragments become visible.


To solve the problem, set the android:background property to “?android:windowBackground” in the fragment layout files.

The “?android:windowBackground” property value is based on the current theme, so no hard coding of the background color is involved. After making the changes, the replaced fragment will appear as shown below.
