Question

Falla de fondo del botón de Android

en el .xml

<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" />

el roundedbutton.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <solid android:color="@color/colorPrimary" />
    <corners android:bottomRightRadius="8dp"
        android:bottomLeftRadius="8dp"
        android:topRightRadius="8dp"
        android:topLeftRadius="8dp"/>

Answer 1

ACTUALIZAR

La solución para esto se incluirá en Android Studio 3.5 Canary 2.

java.lang.IllegalArgumentException: Region.Op no válido: solo INTERSECT y DIFERENCIA

El problema con targetSdkVersion 28

Parece que esto comenzó a aplicarse en P: https://developer.android.com/reference/android/graphics/Canvas#clipRect(android.graphics.RectF,%20android.graphics.Region.Op)

también reportado aquí

• https://issuetracker.google.com/issues/121235731
• https://github.com/facebook/stetho/issues/607
• https://github.com/ArthurHub/Android-Image-Cropper/issues/553
• https://github.com/ArthurHub/Android-Image-Cropper/pull/588

Solución temporal para su caso.

Utilizar

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

en lugar de

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

Answer 2

El mismo problema ocurre al final, se solucionó ahora Cambie el targetSdkVersion 28 to 27 en build.gradle . Gracias

Answer 3

Esto es lo que me lo arregló:

.setCropShape(Build.VERSION.SDK_INT >= Build.VERSION_CODES.P ? CropImageView.CropShape.RECTANGLE : CropImageView.CropShape.OVAL)

Answer 4

Prueba esto

    <shape xmlns:android="http://schemas.android.com/apk/res/android">
    <stroke android:width="2dp" android:color="@color/black"   />
    <solid android:color="@color/black" />
    <corners android:radius="7dp" />

</shape>

Answer 5

intente eliminando "style =" @ android: style / Widget.Button "".

 <Button
            android:id="@+id/button_stop"
            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" />
