Wie erstelle ich UI -Komponenten in einem Jetpack -Komponier -Projekt, das sich ordnungsgemäß an verschiedene mobile Bil ⇐ Android

[Guest]

In verschiedenen Bildschirmgrößen [Pixel 9 vs. Small Phone] enthält die Kartenkomponente - einschließlich des Bildes und der Schaltfläche "Wiederspielen" - perfekt auf dem Pixel 9 -Emulator und entspricht dem Vorschau -Bildschirm. Auf einem kleineren Telefonbildschirm schrumpft die Größe jedoch und die Schaltfläche "Wiederspiele" wird versteckt. Dies kann auf das Bild mit einer festen Größe von 160.DP zurückzuführen sein. Wie kann ich sicherstellen, dass es perfekt auf alle Bildschirme passt, während ich das beabsichtigte Erscheinungsbild von 160.DP beibehält? /strong>
