Android 如何仅在 EditText 底部添加边框？

how add a border only on bottom of EditText?

提问by Manjeet Brar

I saw many related discussions but didn't find a suitable solution. What I need to do is to create a black border on the bottom side of an EditText widget. Is that possible?

我看了很多相关的讨论，但没有找到合适的解决方案。我需要做的是在 EditText 小部件的底部创建一个黑色边框。那可能吗？

I compiled this at my end :

我最后编译了这个：

<?xml version="1.0" encoding="utf-8"?>
    <selector xmlns:android="http://schemas.android.com/apk/res/android">
        <item android:state_pressed="true"><layer-list>
                <item android:bottom="-10dp" android:left="-10dp" android:right="-10dp"><shape>
                        <gradient android:angle="270" android:endColor="#a0e0b071" android:startColor="#a0a67637" />

                        <stroke android:width="10dp" android:color="#5c3708" />

                        <corners android:radius="5dp" />

                        <padding android:bottom="10dp" android:left="10dp" android:right="10dp" android:top="10dp" />
                    </shape></item>
            </layer-list></item>
        <item android:state_enabled="true"><layer-list>
                <item android:bottom="-10dp" android:left="-10dp" android:right="-10dp"><shape android:shape="rectangle">
                        <gradient android:angle="270" android:endColor="#a0a67637" android:startColor="#a0e0b071" />

                        <stroke android:width="10dp" android:color="#5c3708" />

                        <corners android:radius="5dp" />

                        <padding android:bottom="10dp" android:left="10dp" android:right="10dp" android:top="10dp" />
                    </shape></item>
            </layer-list></item>

    </selector>

simple create one edittext_bottom_line.xmlfile in drawablefolder in res

简单 在res 的drawable文件夹中创建一个edittext_bottom_line.xml文件

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

    <item android:bottom="1dp"
        android:left="-2dp"
        android:right="-2dp"
        android:top="-2dp">
        <shape android:shape="rectangle" >
            <stroke
                android:width="0.5dp"
                android:color="@android:color/black" />
        </shape>
    </item>

</layer-list>

To set control's single property like these:

像这样设置控件的单个属性：

 <EditText
     android:id="@+id/editTextEnterPassword"
     android:layout_width="fill_parent"
     android:layout_height="40dp"
    android:background="@drawable/edittext_bottom_line"
    />
