Android Databinding On Inner Class Not Updating Textview

App runs but the TextView doesn't get update here is the relevant code. activity_picker_dashboard.xml

If you want to include a data binding layout from a regular layout, you need to find the root view of the layout and call bind() on it. Maybe something like this:

@OverrideprotectedvoidonCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_picker_dashboard);
    ViewbindingRoot= findViewById(R.id.toolbar);

    LayoutHeaderBindingbinding= LayoutHeaderBinding.bind(bindingRoot);

    ProfileResponse.PayloadprofilePayload=newProfileResponse.Payload();
    profilePayload.setFirstName("Test");

    binding.setProfilePayload(profilePayload);
}

However, it is better to make your Activity's layout a data binding layout and you won't have to do that extra work:

<?xml version="1.0" encoding="utf-8"?><layoutxmlns:android="http://schemas.android.com/apk/res/android"><data><variablename="profilePayload"type="myms.models.ProfileResponse.Payload"/></data><android.support.constraint.ConstraintLayoutandroid:layout_width="match_parent"android:layout_height="match_parent"><!-- Top header --><includelayout="@layout/layout_header"app:profilePayload="@{profilePayload}" /><!-- DrawerLayout --></android.support.constraint.ConstraintLayout></layout>

And then your binding code is much simpler and less error prone:

@OverrideprotectedvoidonCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    ActivityPickerDashboardBindingbinding= 
        DataBindingUtil.setContentView(this, R.layout.activity_picker_dashboard);

    ProfileResponse.PayloadprofilePayload=newProfileResponse.Payload();
    profilePayload.setFirstName("Test");

    binding.setProfilePayload(profilePayload);
}

On a different note, I think Android data binding and butterknife have significant overlap in functionality and I would recommend choosing one or the other, but not both.
