方法有很多种，这里有适合你的方法

Create your own drawable

border.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item >
        <shape
            android:shape="rectangle">
            <solid android:color="@android:color/darker_gray" />
            <corners android:radius="5dp"/>
        </shape>
    </item>
    <item android:right="1dp" android:left="1dp" android:bottom="2dp">
        <shape
            android:shape="rectangle">
            <solid android:color="@android:color/white"/>
            <corners android:radius="5dp"/>
        </shape>
    </item>
</layer-list>

和your_layout.xml

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
   xmlns:tools="http://schemas.android.com/tools"
   android:layout_width="match_parent"
   android:layout_height="match_parent"
   android:orientation="horizontal"
   android:padding="10dp"
   android:background="@drawable/border"
  />

You can also use use a drawable from android

android:background="@android:drawable/toast_frame"

或：

android:background="@android:drawable/dialog_frame"

或：

android:background="@android:drawable/dialog_holo_light_frame"
