Automatic switching between drop-down menus (Android)

Question

I'm trying to automatically switch between dropdown menus.

I have two drop-down menus, when I select the first menu, the second menu content changes depending on this menu, I want it to automatically switch to the second menu and show the list content.

However, it goes to the second menu but does not show its content.

It appears when I click again.

My codes are below. Can you help me?

   <com.google.android.material.textfield.TextInputLayout
        android:id="@+id/dropDownListOuterAccounts"
        style="@style/MyDropDownMenuOuterStyle"
        android:layout_marginTop="16dp"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/toolbar">

        <AutoCompleteTextView
            android:id="@+id/dropDownListAccounts"
            style="@style/MyEditTextInputInnerStyle"

            android:layout_height="wrap_content"
            android:adapter="@{arrayAdapterAccounts}"

        });
