android - 如何为形状添加深度

Question

我需要让我的 EditText 看起来像下图一样有深度。

我有这个形状我不知道要添加什么

<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle" >

    <corners android:radius="50dp" />

    <solid android:color="@color/primary_dark" />

</shape>

你可以用这样的 drawable 来完成:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <!--background to compensate the transparency under shadow and glow (for bigger depth values)-->
    <item>
        <shape android:shape="rectangle">
            <corners android:radius="50dp" />
            <solid android:color="@color/primary_dark" />
        </shape>
    </item>

    <!--top, dark, inner shadow-->
    <item
        android:bottom="@dimen/depth">
        <shape android:shape="rectangle">
            <corners android:radius="50dp" />
            <solid android:color="#1A000000" />
        </shape>
    </item>

    <!--bottom, light, outer glow-->
    <item
        android:top="@dimen/depth">
        <shape android:shape="rectangle">
            <corners android:radius="50dp" />
            <solid android:color="#4DFFFFFF" />
        </shape>
    </item>

    <!--your color-->
    <item
        android:top="@dimen/depth"
        android:bottom="@dimen/depth">
        <shape android:shape="rectangle">
            <corners android:radius="50dp" />
            <solid android:color="@color/primary_dark />
        </shape>
    </item>
</layer-list>

并在dimens.xml中定义一个dimen

<dimen name="depth">2dp</dimen>

通过改变dimen你可以改变drawable的深度
