问题描述

我尝试为自定义按钮添加高度，但结果是:

I tried to add elevation to my custom button but the result is:

如您所见，阴影被剪掉了.我曾尝试在 StackOverflow 和 google 中搜索，但发现了类似的问题，但没有答案:)

As you can see the shadow is clipped. I have tried to search in StackOverflow and google and I found similar question but no answers :)

XML:

<Button
   android:id="@+id/email_sign_in_button"
   android:layout_width="141dp"
   android:layout_height="45dp"
   android:textAlignment="gravity"
   android:text="@string/action_sign_in"
   android:gravity="center_horizontal"
   android:elevation="4dp" />

这是我的自定义按钮样式.

Here is my custom button styles.

button.xml:

<?xml version="1.0" encoding="utf-8"?>

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item
    android:state_enabled="false"
    android:drawable="@drawable/button_disabled" />
<item
    android:state_pressed="true"
    android:state_enabled="true"
    android:drawable="@drawable/button_pressed" />
<item
    android:state_focused="true"
    android:state_enabled="true"
    android:drawable="@drawable/button_regular" />
<item
    android:state_enabled="true"
    android:drawable="@drawable/button_regular" />
</selector>

未按下时的样式.

button_regular.xml:

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<gradient android:angle="-90"
    android:centerX="10"
    android:centerY="10"
    android:endColor="#30bbff"
    android:gradientRadius="10"
    android:startColor="#0081c0"
    android:type="linear"/>
<stroke android:width="5dip" android:color="#ffffff" />
<corners android:radius="20dip"/>
<padding android:left="7dp"
    android:top="7dp"/>
</shape>

推荐答案

您的阴影可能会被 View 的边界剪掉.尝试在按钮底部添加填充.

Your shadows may be getting clipped by the View's bounds. Try adding padding to the bottom of the button.

如果按钮位于父级的底部，则父级 ViewGroup 也可能会裁剪阴影.确保父级具有填充并在父级上设置 android:clipToPadding="false".

If the button sits at the bottom of the parent, the parent ViewGroup may also be clipping the shadow. Make sure the parent has padding and set android:clipToPadding="false"on the parent.
