I've made a "menù" in my BottomSheetDialog the issue is that in the preview all is shown correctly but when i test if on a real device some of TextViews just does not shows the Text!

Here is the XML

While on a real device it's shown as the following:

Some of your TextView tags are using the tools:text attribute:

<TextView
    android:layout_width="match_parent"
    android:layout_height="56dp"
    android:padding="8dp"
    android:textSize="16sp"
    tools:text="Elimina"
    android:gravity="center_vertical"
    app:drawableLeftCompat="@drawable/ic_baseline_delete"
    android:drawablePadding="16dp"/>

The tools namespace is specifically designed to take effect in the Android Studio layout editor preview window, but be ignored when the app is actually run. This lets you put in placeholder values to make writing the XML easier, without affecting the app's behavior.

Change these to android:text and the text will appear when you run the app.
