Change views after inflating from XML

Question

I have made a layout in XML consisting of a LinearLayout having 2 TextViews as its children.

I want to draw a vertical line within the second text view. For that, I created a class and inflated the above XML in its constructor. Now, what methods do I have to override in order to draw the line, and how do I get the Canvas for the text view ?

You can Override onDraw(Canvas canvas) method of the TextView (by creating a custom View that extends TextView) to draw the line. A simpler approach is to use RelativeLayout and put an ImageView with transparent background over the 2nd TextView and with the line and set its visibility to visible when you need to draw the line.

Thank you !! The other method you've given is quite good !! For overriding onDraw(), how will I specify that I want to draw in the second text view. Im getting only a single Canvas right !! – Cygnus Jun 19 '13 at 14:41
Try the update and yes it returns the canvas for this View only. – Mohamed_AbdAllah Jun 19 '13 at 14:50
The code is not working. It says insert a semi colon after the findViewBydId() call. Is there some other way to override the onDraw for the text view ? – Cygnus Jun 19 '13 at 15:16
You can create your own Custom View that extends TextView and overrides onDraw(), however, let me check why the a/m code is not working. – Mohamed_AbdAllah Jun 19 '13 at 15:21
Since it is protected, you must Subclass TextView. Sorry for the confusion. – Mohamed_AbdAllah Jun 19 '13 at 15:42
