How to use a view's reference in xml to pass arguments to a function using data binding?

I am using data binding to call a function of my viewmodel but the function requires the values of the edittext. But I don't know how to pass the value of other views. 
Here is the xml code. In this I want to pass the value of password edittext to viewmodel on click of the button. 
Suggest me a way to do this other than using onclickListeners in fragment and calling the function from there.
 <com.google.android.material.textfield.TextInputLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_margin="@dimen/small_margin"
            android:hint="@string/password_hint">

                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:inputType="textPassword" />

            android:background="@drawable/big_action_button_red"
            android:text
of code specifically responsible for displaying an alert but it also didn't avail. DoThings is a method acting inside MainPage. 
 public async Task DoThings () { 

   if (somethingMissing ()) { 
     Device. BeginInvokeOnMainThread(async () = >

   }

 In MainPage you can judge this code
