I have a Pixel 6 device and updated today Android version to 15.
I test a simple activity for Android 15 and see that a part of top TextView
is hiden.
I guess this is a bug of edge-to-edge mode.
How to disable this mode or fix this problem?
I tryed many ways to show system bar but it always invisible.
This is not a bug, it appears that you are still using Material 2 components you have to handle the insets yourself.
You can temporarily add to your app theme
<item name="android:windowOptOutEdgeToEdgeEnforcement">true</item>
but this will be deprecated/removed in future versions and you will have to handle it anyway. I suggest you look at the code lab on how to handle edge to edge
Updating to Material 3 components will help since components are made to handle edge to edge without the manual work
