All this need's to be done in mainactivity.java

android:id="@+id/text_input_project_name"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginStart="32dp"
android:layout_marginTop="20dp"
android:layout_marginEnd="32dp"
android:hint="Project Name"
app:boxCornerRadiusTopEnd="15dp"
app:boxCornerRadiusTopStart="15dp"
app:endIconMode="clear_text"
app:errorEnabled="true">
<com.google.android.material.textfield.TextInputEditText

To check if a text field is empty, you can do this in your Java code - 

if(textInputLayout.getText().toString().matches(""){
    // Do something
}

You can set the text in the TextInputLayout by using textInputLayout.setText() method in your MainActivity when you want to use it. Check out the documentation here.
