谢谢.

解决方案

此修复程序将包含在 Android Studio 3.5 Canary 2 中

java.lang.IllegalArgumentException: Invalid Region.Op - 只有 INTERSECT 和 DIFFERENCE

targetSdkVersion 28 的问题

看起来这开始在 P 中强制执行:https://developer.android.com/reference/android/graphics/Canvas#clipRect(android.graphics.RectF,%20android.graphics.Region.Op)>

您的情况的临时解决方案

使用

代替

android Button background failure

when I try to add

android:background="@drawable/roundedbutton"

into the .

<Button
     android:id="@+id/button_stop"
     style="@android:style/Widget.Button"
     android:layout_width="match_parent"
     android:layout_height="wrap_content"
     android:layout_margin="3dp"
     android:background="@drawable/roundedbutton"
     android:layout_weight="1"
     android:text="stop"
     android:textSize="18sp" />

the roundedbutton.

<?

the button became blank and Android Studio 3.2.1 gives an error

解决方案

The fix for this will be included in Android Studio 3.5 Canary 2

The issue with targetSdkVersion 28

Temporary solution for your case

Use

<corners
    android:radius="8dp"/>

instead of

<corners android:bottomRightRadius="8dp"
    android:bottomLeftRadius="8dp"
    android:topRightRadius="8dp"
    android:topLeftRadius="8dp"/>
