How to underline TextView in xml (Xamarin.Android)? - xamarin.android

Question

I have to underline the TextViews of the following table:
The only thing I found in internet is:
http://www.apnatutorials.com/android/how-to-underline-text-in-android.php?categoryId=2 (Approach 4)
But the value of the text in that case is hardcoded. In my case there are 9 rows which can change its number. So hardcoding is not solution for me.

You could create a custom TextView and use it in your .axml file.
Create an underline TextView class:
public class UnderlineTextView : TextView
{
public UnderlineTextView(Context context, IAttributeSet attrs) :
base(context, attrs)
{
Initialize();
}
public UnderlineTextView(Context context, IAttributeSet attrs, int defStyle) :
base(context, attrs, defStyle)
{
Initialize();
}
private void Initialize()
{
//this.PaintFlags = this.PaintFlags | Android.Graphics.PaintFlags.UnderlineText;
//this.Text = "This text will be underlined";
String underlineData = this.Text;
SpannableString content = new SpannableString(underlineData);
content.SetSpan(new UnderlineSpan(), 0, underlineData.Length, 0);
// 0 specify start index and underlineData.length() specify end index of styling
this.TextFormatted = content;
}
}
Then, use it in axml:
<yournamespace.UnderlineTextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="I am underline TextView"/>
