Ich bekomme einen Fehler, wenn ich versuche, style="Widget.AppCompat.Button.Colored" zu verwenden. Verwenden der Android-Support-Bibliothek Version 23.2.1. Meine XML-Datei:style = "@ style/Widget.AppCompat.Button.Colored" erzwingt das Schließen der Anwendung
<Button
android:layout_width = "140dp"
android:layout_height = "90dp"
android:text = "Camera"
android:id = "@+id/cameraButt"
android:textAllCaps = "false"
android:textColor = "@color/textColorPrimary"
android:layout_marginLeft = "5sp"
android:layout_marginRight = "5sp"
android:layout_marginTop = "4sp"
style="@style/Base.Widget.AppCompat.Button.Colored"/>
Und es perfekt in 5.0 ++ Version arbeiten, aber nicht in pre Lutscher.
