Android Scrollview Höhe Dynamische Anpassung

Question

Ich habe eine NestedScrollview in einem CoordinatorLayout. Jetzt gibt es 5-6 Ansichten innerhalb von NestedScrollview und die Sichtbarkeit wird abhängig von den Daten über das Netzwerk ändern. Das Problem ist, dass scrollview immer die gleiche Höhe (insgesamt alle 5-6 Ansichten) und lässt eine leere Stelle am unteren Rand, wenn ich die Sichtbarkeit einer Ansicht ausblenden. Könnten Sie mir bitte sagen, wie ich die Höhe des Scrollview anpassen kann, so dass es keinen leeren Platz am unteren Rand des Scrollview gibt.

<android.support.design.widget.CoordinatorLayout 
    android:id="@+id/main_content"

    android:orientation="vertical">

Dies ist NestedScrollview. Unten ist das profile_extra_details_layout. Dies ist das Layout, dessen Sichtbarkeit basierend auf der Datenverfügbarkeit aus dem Netzwerk und dem Typ des Benutzers, dessen Profil angezeigt wird, gesteuert wird.

Bitte lassen Sie mich wissen, wenn ich mehr überall ausarbeiten muss.

Answer 1

Sie Dies würde helfen: , wenn Sie die Ansicht Verwendung View.GONE verstecken, ich glaube, Sie nestedscrollview Höhe View.INVISIBLE

Answer 2

Versuch zu ändern, um zu match_parent und das Kind lineare Layout Höhe wrap_content verwenden. Danach ändern Sie die Sichtbarkeit des untergeordneten Layouts des linearen Layouts zur Laufzeit.
