如何在Android中设置视图的边框底部

Question

我试图通过使用layer-list drawable设置Android中TextView的底部边框，但是问题是我看到底部的角落有点向上，但是textview下的直线不是。我希望它是不弯曲的完美直线。

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="rectangle">
            <!-- draw a 4 dp width border around the rectangle shape -->
            <stroke android:color="@color/colorPrimary" android:width="2dp"/>
        </shape>
    </item>
    <!--
        hide left, top and right side border using white color
        by padding 4 dp bottom side
    -->
    <item android:bottom="3dp">
        <shape android:shape="rectangle">
            <solid android:color="@android:color/white"/>
        </shape>
    </item>
</layer-list>




  <TextView
        android:gravity="center"
        android:text="@string/eat"
        android:textSize="12sp"
        android:background="@drawable/border_bottom_green_tab"
        android:paddingTop="5dp"
        android:paddingBottom="5dp"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

Answer 1

这将为您工作，只需将 android：bottom

的3dp更改为1dp

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

            <stroke android:color="@color/colorPrimary" android:width="2dp"/>
        </shape>
    </item>

    <item android:bottom="1dp">
        <shape android:shape="rectangle">
            <solid android:color="@android:color/white"/>
        </shape>
    </item>
</layer-list>

Answer 2

只需在前solid中使用stroke而不是item

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
    <shape android:shape="rectangle">
        <!-- draw a 4 dp width border around the rectangle shape -->
        <solid android:color="@color/colorPrimary" />
    </shape>
</item>
<!--
    hide left, top and right side border using white color
    by padding 4 dp bottom side
-->
<item android:bottom="3dp">
    <shape android:shape="rectangle">
        <solid android:color="@android:color/white" />
    </shape>
</item>
