Here is sample style for borderline on text..

Style.xml

<resources xmlns:android="http://schemas.android.com/apk/res/android">
 <style name="shadoweffect">
        <item name="android:paddingLeft">4px</item>
        <item name="android:paddingBottom">4px</item>
        <item name="android:textColor">#FFFFFF</item>
        <item name="android:textSize">25sp</item>
        <item name="android:shadowColor">#000000</item>
        <item name="android:shadowDx">0</item>
        <item name="android:shadowDy">0</item>
        <item name="android:shadowRadius">3</item>
    </style>

</resources>

Apply style on your TextView

 <TextView
      style="@style/shadoweffect"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:text="your_text" />

Android does not have such feature originally. A few months ago, I had to develop a similar feature, and I used some trick. In that case I used the shadow attribute. In your case on TextView.onDraw() call super() two times. Set the typeface to bold and set the color to border color and call one time, and set normal and call second time. That will work.
