You need to create a custom background 9-patch image like this one and put it to /res/drawable directory. Here is the tutorial for 9-patch images. Then you need to apply the image as a background for your EditText using android:background attribute.

Here is a sample layout xml:

<EditText
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content"
    android:background="@drawable/white_bg"
    android:text="Test"
    android:layout_marginBottom="5dip" /> 

<EditText
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content"
    android:background="@drawable/white_bg"
    android:text="Currently focused" />

And here is the result:
