android Edittext如何让字体描边 网上都是Textview

main.xml

<?xml version="1.0" encoding="utf-8"?>
 android:layout_width="fill_parent"
 android:layout_height="fill_parent"
 android:background="@drawable/bg"
 android:orientation="vertical" >
<EditText
    android:id="@+id/et"
    android:layout_width="251dp"
    android:layout_height="wrap_content"
    android:layout_gravity="center" 
    android:drawableLeft="@drawable/title"
    android:background="@drawable/shape"
    android:padding="10px"
    android:hint="北京"
    android:singleLine="true"
    android:textColor="#FFFAFA"/>

在drawable中建一个xml文件：shape.xml

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

 android:width="2px" 
 />
