Use android:maxLength="32"

Hope this helps.

If you want second text show only in first line you can do this

<TextView
    android_id="@+id/textView_profile_name"
    android_layout_width="0dp"
    android_layout_height="wrap_content"
    android_textColor="@color/dark_gray"
    android_textSize="@dimen/textSize"
    app_layout_constrainedWidth="true"
    android_fontFamily="@font/helvetica_neue_light"
    android_maxLines="1"
    android_text="Hello"
    app_layout_constraintStart_toEndOf="@id/img_profile"
    app_layout_constraintEnd_toStartOf="@id/textView_profile_device_count"
    app_layout_constraintTop_toTopOf="parent" />

<TextView
    android_id="@+id/textView_profile_device_count"
    android_layout_width="wrap_content"
    android_layout_height="wrap_content"
    android_layout_marginEnd="@dimen/dp30"
    android_layout_marginStart="@dimen/dp_5"
    android_singleLine="true"
    app_layout_constrainedWidth="true"
    app_layout_constraintEnd_toStartOf="@id/img_arrow"
    android_textSize="@dimen/textSize"
    app_layout_constraintTop_toTopOf="parent"
    android_maxLines="1"
    android_fontFamily="@font/helvetica_neue_light"
    android_textColor="@color/dark_gray"
    app_layout_constraintBottom_toBottomOf="@id/img_profile"
    android_text="(3 Devices)" />

With this, you second text will always stay in first line. And first text length will set to 0dp it means that first text length will start from end of img_profile to start of textView_profile_device_count

But it may still have some problem if text of first textview wider than width of textview, and it will not fully show.

PS. Sorry for my bad English.

My question is both are two separate textviews “Hello” and “World” First textview has character limit of 32. How can I make it wrap content if text exceeds the limit and make “World” stay in first line?

Below is the image thats how its acting currently.

Below is the code which I tried to implement. I tried to write min_ems, max_ems and ems but its not looking good in tablet.

<ImageView
    app_layout_constraintStart_toStartOf="parent"
    android_id="@+id/img_profile"
    android_layout_width="@dimen/image_width"
    android_layout_height="@dimen/image_height"
    android_src="@drawable/active_profile"
    app_layout_constraintTop_toTopOf="parent"
    app_layout_constraintRight_toLeftOf="@id/textView_profile_name"
    tools_ignore="ContentDescription" />

<TextView
    android_id="@+id/textView_profile_name"
    android_layout_width="wrap_content"
    android_layout_height="wrap_content"
    android_textColor="@color/dark_gray"
    android_textSize="@dimen/textSize"
    app_layout_constrainedWidth="true"
    android_fontFamily="@font/helvetica_neue_light"
    android_text="Hello"
    app_layout_constraintLeft_toRightOf="@id/img_profile"
  app_layout_constraintRight_toLeftOf="@id/textView_profile_device_count"
    android_maxLines="2"
    android_maxEms="12" **//this code can be a typo I added in stackoverflow**
    android_minEms="2"    **//this code can be a typo I added in stackoverflow**
    app_layout_constraintTop_toTopOf="parent" />

<TextView
    android_id="@+id/textView_profile_device_count"
    android_layout_width="wrap_content"
    android_layout_height="wrap_content"
    android_layout_marginEnd="@dimen/dp30"
    android_layout_marginStart="@dimen/dp_5"
    android_singleLine="true"
    app_layout_constrainedWidth="true"
    app_layout_constraintStart_toEndOf="@id/textView_profile_name"
    app_layout_constraintEnd_toStartOf="@id/img_arrow"
    android_textSize="@dimen/textSize"
    app_layout_constraintTop_toTopOf="parent"
    android_maxLines="1"
    android_fontFamily="@font/helvetica_neue_light"
    android_textColor="@color/dark_gray"
    app_layout_constraintBottom_toBottomOf="@id/img_profile"
    android_text="(3 Devices)" />

<ImageView
    tools_ignore="ContentDescription"
    android_id="@+id/img_arrow"
    android_layout_width="@dimen/dp20"
    app_layout_constraintTop_toTopOf="parent"
    app_layout_constraintLeft_toRightOf="@id/textView_profile_device_count"
    app_layout_constraintVertical_weight="1"
    android_layout_height="@dimen/dp20"
    android_src="@drawable/ic_arrow_forward_black_24dp"
    app_layout_constraintEnd_toEndOf="parent"
/>
