I have a problem with creating a chat layout.

How can I force TextView's text to fill up the entire area?
Even if the string is continuous, sometimes text goes to the next line.

XML with TextView:

<?xml version="1.0" encoding="utf-8"?>

<androidx.constraintlayout.widget.ConstraintLayout

xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:app="http://schemas.android.com/apk/res-auto"

xmlns:tools="http://schemas.android.com/tools"

android:layout_marginBottom="4dp"

android:layout_width="match_parent"

android:layout_height="wrap_content">



<TextView

    android:id="@+id/my_msg"

    android:layout_width="wrap_content"

    android:layout_height="wrap_content"

    android:background="@drawable/message_my_shape"

    android:paddingLeft="16dp"

    android:paddingTop="8dp"

    android:paddingRight="16dp"

    android:paddingBottom="8dp"

    android:text="Hey mate,how youre doing?"

    android:textColor="#fcc7d3"

    android:textSize="16sp"

    app:layout_constraintEnd_toEndOf="parent"

    app:layout_constraintHorizontal_bias="1.0"

    app:layout_constraintStart_toStartOf="parent"

    tools:layout_editor_absoluteY="0dp" />



</androidx.constraintlayout.widget.ConstraintLayout>

UPD:
You don't quite get me, guys. Padding should be there and I don't want a single line, please see the new screenshots with layout boundaries shown to see what I'm talking about.
Question is still the same, why text in TextView doesn't fill all available space (sometimes)?

This reason why this happens is that you didn't specify that your TextView only has one line.

From the documentation:

android:maxLines

Makes the TextView be at most this many lines tall. When used on an
editable text, the inputType attribute's value must be combined with
the textMultiLine flag for the maxLines attribute to apply.

So if you want to always have a single line of text use:

android:maxLines=1

Anything this to your code:

<TextView

    android:id="@+id/my_msg"

    android:layout_width="wrap_content"

    android:layout_height="wrap_content"

    android:background="@drawable/message_my_shape"

    android:paddingLeft="16dp"

    android:paddingTop="8dp"

    android:paddingRight="16dp"

    android:paddingBottom="8dp"

    android:text="Hey mate,how youre doing?"

    android:textColor="#fcc7d3"

    android:textSize="16sp"

    android:maxLines=1

    app:layout_constraintEnd_toEndOf="parent"

    app:layout_constraintHorizontal_bias="1.0"

    app:layout_constraintStart_toStartOf="parent"

    tools:layout_editor_absoluteY="0dp" />

Found a solution.

For API 23 and higher add to your TextView:

android:breakStrategy="simple"

For API < 23 remove hidden   from you text dynamically (android adds them automatically).

code is correct give the space between the words

not : "jhjhhjhjhhjhddfhdjfdfdfgdjdjfdj"

try : Hey mate,how youre doing how are youre doing how youre doing how youre doing ?

android:layout_width="match_parent" // if needed
