Android EditText not expanding with multiline

Question

I have EditText in a chat layout, that is supposed to expand when the user is typing more than one line. I used android:inputType="textMultiLine|textNoSuggestions" but it's not working. I tried to use android:singleLine="false" and

write_et.setInputType(InputType.TYPE_CLASS_TEXT or InputType.TYPE_TEXT_FLAG_MULTI_LINE or InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS)
write_et.setSingleLine(false)

but it's still not working. This is my code:

<androidx.constraintlayout.widget.ConstraintLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:layout_width="match_parent" xmlns:app="http://schemas.android.com/apk/res-auto"
        android:background="@android:color/white"
        android:layout_height="match_parent"
        tools:context="com.improve.myproject.fragments.ChatFragment">

    <androidx.recyclerview.widget.RecyclerView
            android:id="@+id/rv"
            android:layout_marginStart="16dp"
            android:layout_marginEnd="16dp"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            app:layout_constraintTop_toTopOf="parent"
            app:layout_constraintLeft_toLeftOf="parent"
            app:layout_constraintBottom_toTopOf="@id/send_btn"
            android:layout_marginBottom="8dp"
            android:layout_marginTop="8dp"/>

        <ImageView
                android:id="@+id/send_btn"
                android:layout_width="40dp"
                android:layout_height="40dp"
                android:layout_margin="16dp"
                android:padding="8dp"
                android:background="@drawable/send_shape"
                android:src="@drawable/ic_arrow_back_white_24dp"
                app:layout_constraintLeft_toLeftOf="parent"
                app:layout_constraintBottom_toBottomOf="parent"
                android:contentDescription="to info"
                android:tooltipText="@string/take_out_frustration"/>

        <EditText
                android:id="@+id/write_et"
                android:inputType="textMultiLine|textNoSuggestions"
                android:singleLine="false"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                app:layout_constraintBottom_toBottomOf="parent"
                app:layout_constraintRight_toRightOf="parent"
                app:layout_constraintLeft_toRightOf="@id/send_btn"
                android:background="@drawable/text_sender_bg"
                android:layout_marginEnd="16dp"
                android:layout_marginStart="16dp"
                android:layout_marginBottom="16dp"
                android:padding="8dp"
                android:paddingStart="16dp"
                android:paddingEnd="16dp"
                android:textColor="@color/colorPrimary"
                android:textSize="20sp"
                android:textColorHint="#7EB2F5"
                android:hint="@string/type_here_chat"
                android:fontFamily="@font/comixno2_medium"/>

</androidx.constraintlayout.widget.ConstraintLayout>

EDIT: As @Md. Asaduzzaman showed the problem is not in the xml.

for this xml I have a fragment with firebase realtime listener, setOnClickListener for the send button uploading a message to firebase realtime, and hide keyboard function, when you click on the send button.

Do anyone know what could make this behavior happen?

PROBLEM FOUND: The problem was that in my Manifest I wrote windowSoftInputMode="adjustPan" so my solution was to change it to adjustResize and handle the movement of other layouts by myself.

I have tried your xml code only like below:

<EditText
    android:id="@+id/write_et"
    android:inputType="textMultiLine|textNoSuggestions"
    android:singleLine="false"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintRight_toRightOf="parent"
    app:layout_constraintLeft_toRightOf="@id/send_btn"
    android:background="#d3d3d3"
    android:layout_marginEnd="16dp"
    android:layout_marginStart="16dp"
    android:layout_marginBottom="16dp"
    android:padding="8dp"
    android:paddingStart="16dp"
    android:paddingEnd="16dp"
    android:textColor="@color/colorPrimary"
    android:textSize="20sp"
    android:textColorHint="#7EB2F5"
    android:hint="type_here_chat"/>

And the output something like that
