J'utilise CoordinatorLayout avec NestedScrollView . Mais il semble que NestedScrollView ne puisse pas faire défiler tout son contenu.
Code de mise en page
class TestFragment : Fragment() {
private lateinit var rootView: View
private lateinit var collapsingToolbar: CollapsingToolbarLayout
override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {
// Inflate the layout for this fragment
rootView = inflater.inflate(R.layout.collapsing_toolbar_layout, container, false)
collapsingToolbar = rootView.findViewById(R.id.collapsing_toolbar)
collapsingToolbar.title = "Collapsing Layout"
collapsingToolbar.setCollapsedTitleTextColor(ContextCompat.getColor(activity!!, android.R.color.white))
return rootView
}
}
Voici kotlin code

android:text="Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).There are many variations of passages of Lorem Ipsum available, but the majority have suffered alteration in some form, by injected humour, or randomised words which don't look even slightly believable. If you are going to use a passage of Lorem Ipsum, you need to be sure there isn't anything embarrassing hidden in the middle of text. All the Lorem Ipsum generators on the Internet tend to repeat predefined chunks as necessary, making this the first true generator on the Internet. It uses a dictionary of over 200 Latin words, combined with a handful of model sentence structures, to generate Lorem Ipsum which looks reasonable. The generated Lorem Ipsum is therefore always free from repetition, injected humour, or non-characteristic words etc." />

Ici, vous pouvez voir que le contenu ne s'affiche pas jusqu'à la fin. J'ai essayé plusieurs solutions mais ne semble pas fonctionner.
Toute aide appréciée.

Try to add paddingBottom="100dp" to your NestedScrollView , if that doesn't work then try with adding it to TextView .
Hope it helps.

J'utilise AndroiX insted of support libarary, et com.google.android.material également
La migration vers androidX peut être effectuée en utilisant android studio Refactor-> Migrer vers AndroidX
Essayez d'encapsuler votre vue de texte avec une mise en page de contraintes.
J'utilise androidx et j'ai eu le même problème, je le pirate avec ça.
<androidx.core.widget.NestedScrollView
android:id="@+id/scroll"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:clipToPadding="false"
app:layout_behavior="com.google.android.material.appbar.AppBarLayout$ScrollingViewBehavior">
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginBottom="?attr/actionBarSize">
<!-- other things -->
</FrameLayout>
</androidx.core.widget.NestedScrollView>
Je recherche beaucoup et teste beaucoup de code mais il n'y a pas de bonne solution, découvrez simplement que nous avons besoin une plus grande hauteur de barre d'outils dans NestedScrollView pour afficher tout le contenu!
Dieu bénisse Google et tous ses développeurs du SDK Android :)
