I am using Floating Action Button and I want to change the background color.

这是我的代码

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/btnfab"
        android:layout_width="48dp"
        android:layout_height="48dp"
        android:layout_alignParentBottom="true"
        android:layout_alignParentEnd="true"
        android:layout_alignParentRight="true"
        android:layout_gravity="right|center_vertical"
        android:layout_marginBottom="20dp"
        android:src="@drawable/search" />

这是我用来尝试实现此目标的代码:

Here is the code I am using to try and achieve this:

如图所示，我也在FAB上遇到了麻烦.我应该如何去除那些角落阴影?

I am also getting corners on my FAB as shown in image. How should I remove those corner shadows?

推荐答案

您可以通过将以下属性添加到FloatingActionButton:

You can remove problematic shadow by adding this attributes to your FloatingActionButton:

app:borderWidth="0dp"
app:elevation="6dp"

FloatingActionButton没有背景色.您可以通过以下方式更改该组件的颜色:

There is no background color for FloatingActionButton. You change this component color by:

app:backgroundTint="@color/YOURCOLOR"

记住要在您的父级布局中包含以下行:

Remember to have in your parent layout following line:

xmlns:app="http://schemas.android.com/apk/res-auto"
