EditText in TextInputLayout lagging

Question

I have two views using TextInputLayout. The first one is a login view which has only 2 input fields and the second one is a register view which has many input fields. I am using TextInputLayout and EditText/AppCompatEditText with custom themes for my inputs.
The problem is, when i click on my EditText's in my Register screen i get a kind of lag/spikes on the default TextInputLayout animation. I don't get the lag in my LoginScreen but the code I'm using is quite the same, so i suppose the problem is in the number of inputs. Any idea or thoughts?
Here is my register code:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

Answer 1

I believe that the reason for the lag is that the hint animation of TextInputLayout and the adjustment made to the activity's main window happening at the same time (because of showing soft keyboard).

In my case using android:windowSoftInputMode="adjustNothing" inside the activity tag in Manifest does the job, because it makes keyboard appear over the content without any adjustment made to the activity's main window, however it is up to you to decide if keyboard can overlay your TextInputLayout.

As the last option we can set app:hintAnimationEnabled="false" to the TextInputLayout.
