</RelativeLayout> 

Ich bin neu in Android-Programmierung. Das Layout wird bei einigen Geräten korrekt angezeigt und bei anderen Geräten abgeschnitten. Ich habe Ränder wie "@ dimen/activity_horizontal_margin" im XML für das Layout hinzugefügt. Ich habe erwartet, dass diese nach der Bildschirmgröße berechnet werden, aber das ist nicht der Fall. Wie kann ich die Marge angeben, die nach dem verfügbaren Platz berechnet wird?

Answer 1

Zuerst ist es nicht gut, dass Sie so viele ineinander eingepackte Layouts haben. Und zweitens, ist sehr schlecht, Gewicht in diesen Fällen zu verwenden, da Android viel Zeit braucht, um den Wert in der tiefsten Komponente zu zählen.

Auf diese Weise müssen Sie besser TableLayout für die gleichen Zwecke verwenden.
