Hello, i want to change the border color/background of my LinearLayout programatically based on EditText focus. after doing some research, i found that you can easily changed it by using the drawable file method, i.e: android:state_focused="true".

while this is working when i apply it on the EditText alone, there is a case where i need to put 2 icon images inside the LinearLayout together with EditText, i have tried to use some workaround of it by using FrameLayout, while it workout quite well, i'm still trying whether if i able to do it while using LinearLayout . so i wonder if anyone know how to do it on LinearLayout ?

below is my code for the structure of the LinearLayout :

<LinearLayout
        android:id="@+id/linear_textfield"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:focusable="true"
        android:focusableInTouchMode="true"
        android:background="@drawable/textfield_background"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toBottomOf="@id/textfield_title">

        <EditText
            android:id="@+id/edittext_field"
            android:layout_width="0dp"
            android:layout_height="50dp"
            android:layout_weight="1"
            android:background="@android:color/transparent"
            android:hint="Placeholder text"
            android:paddingHorizontal="16dp"
            style="@style/body_text_medium"
            android:textColor="@android:color/darker_gray"/>

        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_vertical|end"
            android:src="@drawable/icon_1"
            android:layout_marginEnd="8dp"
            android:layout_marginRight="8dp" />

        <ImageView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginRight="16dp"
            android:layout_gravity="center_vertical|end"
            android:src="@drawable/icon_2"
            android:layout_marginEnd="16dp" />

    </LinearLayout>
