Question

我正在尝试在Android Studio的设计模式下添加ToggleButton。

我的目标是API级别28 targetSdkVersion 28

我的ToggleButton没有显示，我看到了该错误： java.lang.IllegalArgumentException: Invalid Region.Op - only INTERSECT and DIFFERENCE are allowed

这是ToggleButton的xml

 <ToggleButton
            android:text="ToggleButton"
            android:layout_width="100dp"
            android:layout_height="100dp" tools:layout_editor_absoluteY="369dp"
            tools:layout_editor_absoluteX="133dp" android:id="@+id/toggleButton5" android:textOff="OFF"
            android:textOn="ON" android:textColor="@color/colorAccent" style="@style/AlertDialog.AppCompat"
            tools:text="Hello" android:typeface="normal" android:textStyle="bold" android:textAlignment="center"
    />

显然clipRect (RectF rect, Region.Op op)在API 26中已被弃用，但是我不确定需要更改哪些内容？

这是完整的堆栈跟踪：

Android（API级别28），无效Region.Op-仅允许INTERSECT和DIFFERENCE
