向 EditText 字段添加阴影效果 [英] Add drop shadow effects to EditText Field

问题描述

我正在尝试设计一个具有像这样的阴影(底部和右侧)的 EditText 字段

I am trying to design an EditText Field having Shadows (bottom and right side) like this

尝试谷歌搜索和搜索了很多 SO 讨论，但都是针对 TextView 而不是 EditText.

tried googling & hunted many SO discussions but all are for TextView not EditText.

这是我在输入文本中添加阴影而不是在文本字段中添加阴影的代码

This is my code adding shadow to Input Text but not to TextField

<EditText android:id="@+id/txtpin" 
        android:maxLength="4" 
        android:layout_marginLeft="10dp" 
        android:layout_height="37dp" 
        android:gravity="center_horizontal" 
        android:inputType="textPassword" 
        android:longClickable="false" 
        android:layout_width="160dp" 

        android:shadowColor="@color/Black"
        android:shadowDx="1.2"
        android:shadowDy="1.2"
        android:shadowRadius="1.5" 

        android:background="@color/White">
            <requestFocus></requestFocus>
        </EditText>

我猜它需要一些可绘制的自定义 xml 视图，但没有得到确切的想法.实现这一目标的逻辑是什么.

I guess it needs some custom xml view in drawable but not getting exact idea. What will be the logic to achieve this.

任何帮助将不胜感激.

推荐答案

嗯.. @Shalini 的回答以这种方式帮助了我，但我仍然有另一种方法可以使用 EditText Field 实现 2D 阴影，我将与您分享.

Well.. @Shalini's answer helped me in this way but still I got another way to achieve 2D shadow with EditText Field and I am going to share with you.

我们需要为 EditText 创建具有三层的自定义 XML 视图，底部阴影和右侧阴影

We need to create custom XML view with three layer for EditText, bottom shadow and right side shadow

下面是我的代码.

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

<!-- most important is order of layers -->

    <!-- Bottom right side 2dp Shadow -->
    <item >
        <shape android:shape="rectangle">
            <solid android:color="#000000" />           
        </shape>
    </item>

    <!-- Bottom 2dp Shadow -->
    <item>
        <shape android:shape="rectangle">
            <solid android:color="#000000" />   
        </shape>
    </item>

    <!-- White Top color -->
    <item android:bottom="3px" android:right="3px">
        <shape android:shape="rectangle">
            <solid android:color="#FFFFFF" />           
        </shape>
    </item> 
</layer-list>

现在我们可以使用Background"属性将此阴影视图设置为我们的 TextField

Now we can set this shadow view to our TextField using "Background" property

喜欢这个

<EditText android:layout_width="wrap_content" 
            android:id="@+id/txtpin"  
            android:maxLength="4" 
            android:layout_height="37dp" 
            android:gravity="center_horizontal" 
            android:longClickable="false" 
            android:padding="2dp"

            android:inputType="textPassword|number" 
            android:password="true" 
            android:background="@drawable/edittext_shadow" 
            android:layout_weight="0.98" 
            android:layout_marginLeft="15dp">
                <requestFocus></requestFocus>
   </EditText>

<小时>

结果屏幕就像我在上面发布的问题一样.
