I modified Rodrigo's solution to use an adapter, i.e. more like a standard Spinner https://gist.github.com/smithaaron/d2acd57937d7a4201a79

Here is my trick,

the good things is that everything will work like you want,

but the bad is that it is increasing layout hierarchy, and you have to handle functionality in code, and it is an ugly solution:

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <android.support.design.widget.TextInputLayout
            android:id="@+id/til"
            android:layout_width="match_parent"
            android:layout_height="wrap_content">

            <EditText
                android:id="@+id/edt"
                android:layout_width="match_parent"
                android:layout_height="@dimen/edt_height"
                android:hint="@string/create_gcc_visa_txt_step" />

        </android.support.design.widget.TextInputLayout>

        <Spinner
            android:id="@+id/spn"
            style="@style/MyAppTheme.Base.Spinner"
            android:layout_height="@dimen/edt_height"
            android:layout_alignBottom="@id/til" />

    </RelativeLayout>

and override adapter for spinner, to make selected values transparent

public class MySpinnerAdapter extends SimpleAdapter {
    Context mContext;

    public MySpinnerAdapter(Context context, List<String> data, int resource, String[] from, int[] to) {
        super(context, data, resource, from, to);
        mContext = context;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        convertView = super.getView(position, convertView, parent);

        TextView tv = (TextView) convertView.findViewById(android.R.id.text1);
            tv.setTextColor(ContextCompat.getColor(mContext, R.color.transparent));
        return convertView;
    }
}

and after selecting in spinner, just get selected text and set it to EditText and it will have the same effect with animation

yourSpinnerView.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
        @Override
        public void onItemSelected(AdapterView<String> adapterView, View view, int i, long l) {
            //get your selected text from adapter or from where you want 
            String selectedText = adapterView.getItemAtPosition(i));

            if (i != 0) { 
                edt.setText(selectedText);
            } else { 
                // if in case your spinner have first empty text, 
                // then when spinner selected, just empty EditText.
                edt.setText("");
            }
        }

        @Override
        public void onNothingSelected(AdapterView<?> adapterView) {

        }
    });

You can achieve this :

With new Material library styles like this:

<com.google.android.material.textfield.TextInputLayout
        android:id="@+id/fullNameLay"
        style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox.ExposedDropdownMenu"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">

    <androidx.appcompat.widget.AppCompatAutoCompleteTextView
            android:id="@+id/fullNameEt"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"/>
</com.google.android.material.textfield.TextInputLayout>
