棒棒糖上的FloatingActionButton阴影

问题描述

我想通过自定义宽度和高度将我的FloatingActionButton变得更大.我发现只有在FrameLayout或CoordinatorLayout中将其添加为子级时，才有可能.在棒棒糖和棉花糖上看起来不错.但是在棒棒糖之前，来自FloatingActionButton的阴影非常奇怪.是来自Android的错误还是我做错了什么?

I want to make my FloatingActionButton much bigger with custom width and height. I find out that this is possible only if I add this as a child in FrameLayout or in CoordinatorLayout. On Lollipop and Marshmallow it looks good. But on pre-Lollipop the shadow from FloatingActionButton is very strange. Is it a bug from Android or I did something wrong?

<android.support.design.widget.CoordinatorLayout
    android:id="@+id/help_layout"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true">

    <android.support.design.widget.FloatingActionButton
        android:id="@+id/my_btn"
        android:layout_width="150dp"
        android:layout_height="150dp"
        android:layout_gravity="center"
        android:src="@mipmap/ic_launcher" />

</android.support.design.widget.CoordinatorLayout>

我也尝试添加和app:borderWidth="0dp"，但是没有运气.

I also tried to add and app:borderWidth="0dp" but with no luck.

这是奇巧(Kitkat)的样子:

推荐答案

Fab按钮在两个默认尺寸下可用.普通(56dp)，迷你(40dp)

Fab button is available under two default dimensions.Normal (56dp),Mini (40dp)

但是您可以通过在dimens.xml中(在值下方)添加以下代码来覆盖此值.

But you can override this values by adding followings code in dimens.xml (under values).

<dimen name="design_fab_size_normal">150dp</dimen>
<dimen name="design_fab_size_mini">30dp</dimen>
