<ImageButton
android:id="@+id/btn_scan_qr"
android:layout_width="216dp"
android:layout_height="203dp"
android:elevation="10dp"
android:background="@drawable/roundbutton"
android:src="@drawable/ic_power_settings_new_black_24dp"
android:textSize="15dp"
tools:layout_editor_absoluteX="97dp"
tools:layout_editor_absoluteY="225dp"
/>
这是Xml代码
<item android:state_pressed="false"
>
<shape android:shape="oval">
<corners android:radius="40dp" />
<solid android:color="#FFFFFF"
/>
<padding
android:bottom="40dp"
android:left="40dp"
android:right="40dp"
android:top="40dp" />
</shape>
</item>
这是关于椭圆形状的可绘制代码,我想添加它的阴影,我已经使用了立面,但它在约束布局中没有做任何事情,但它在线性布局中做了,但它在正方形中显示阴影,但我希望它在圆形中显示。
请尝试以下代码
椭圆型视图与shadowcustom_bg.xml。
