You could use parent LinearLayout view and make it roundtable using shapes (like the other answer). Then just put any number of EditText views and use separator view between them.
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle" >
<solid android:color="#ffffff" />
<stroke android:width="1dip" android:color="#000000"/>
<corners android:radius="3dp" />
</shape>
using the following xml code to create a new drawable and set it as background to your LinearLayout that contains EditViews.
