如何在textview单元格的底部添加1dp行(而不是表格布局)

Question

我是android的新手,jsut是一个非常简单的简单问题,我如何在文本视图中添加一个底线,以便它在单元格的底部显示为1dp,这是到目前为止的代码:

<?xml version="1.0" encoding="UTF-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="47.5dp"
        android:layout_marginLeft="2dp"
        android:layout_marginRight="2dp"
        android:paddingTop="13dp"
        android:background="@drawable/line_str"
        android:paddingLeft="8dp"
        android:text="@string/manage_categories"
        android:singleLine="true"
        android:textColor="@color/white"
        android:fontFamily="Roboto-Regular"
        android:layout_gravity="center"
        android:textSize="16sp"
        />

line_str.xml如下:

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


<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<!-- This is the main color -->
<item>
  <shape>
        <solid android:color="@color/black" />
  </shape>
</item>
<!-- This is the line -->
<item android:bottom="1dp">
 <shape>
       <solid android:color="#252525" />
 </shape>
</item>
</layer-list>

任何帮助赞赏.谢谢!

我将一个水平扩展的9patch图像并将其添加到textview的drawableBottom属性.

至于图层列表方法试试这个:

<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<!-- This is the main color -->
<item>
  <shape>
        <size android:height="@dimen/textViewHeight"/>
        <solid android:color="@color/black" />
  </shape>
</item>
<!-- This is the line -->
<item android:top="@dimen/textViewHeight">
 <shape>
       <size android:height="1dp"/>
       <solid android:color="#252525" />
 </shape>
</item>
</layer-list>
