问题 I was using Material design 1.1.0 . For tabs with viewpager2 I updated it to '1.2.0-alpha05' Material library version it was working fine for single module but was crashing for another module where I've developed my custom material designed TextInputLayout. I changed theme from 'Theme.AppCompat.Light.NoActionBar' to Theme.MaterialComponents.Light.NoActionBar and crash fixed. After fixing crash and upgrading theme it is showing me white floating label , buttons , indiators etc anyone please

问题 Let's say I've got an Activity with only a FrameLayout ( I've also try with the new FragmentContainerView ) so I will be loading Fragments on it. Let's assume I've got two Fragments: fragA and fragB , I will first load fragA and with a button, present in that fragment, replace it with fragB .

问题 I have an Activity that contains an EditText on 3.1. Based on user input, I change the color of the text in the EditText (red for an error), and then reset it to black when the text is OK. One issue relates to changing the overall theme of the Activity. For instance, changing it to the regular dark theme from the light theme results in the black text being shown against a black background - so I need to go in and change the code, instead resetting the text to white when the data is OK.

问题 I'm using MotionLayout to build UI with 2 parts - top one with some view and bottom one with SwipeRefresh and RecyclerView inside.

While my
