Is there an easy way to strike through text in an app widget

Question

I was wondering if there is an easy way to strike text within an app widget in Android  In a normal activity  it is pretty easy  using textview flags   textView setPaintFlags textView getPaintFlags     Paint STRIKE THRU TEXT FLAG     But since in an app widget  I can use only remoteviews    I do not know if this is possible  Anyone know something about this   Thanks

For multiline TextView you should use android text style CharacterStyle like this   SpannableString spannable   new SpannableString text   spannable setSpan new StrikethroughSpan    0  text length    Spanned SPAN INCLUSIVE EXCLUSIVE   remoteViews setTextViewText R id itemText  spannable

Another way to do it programmatically which looks a bit less like a hack than the Paint way   Instead of doing   tv setText s     do   private static final StrikethroughSpan STRIKE THROUGH SPAN   new StrikethroughSpan        tv setText s  TextView BufferType SPANNABLE   Spannable spannable    Spannable  tv getText    spannable setSpan STRIKE THROUGH SPAN  0  s length    Spanned SPAN EXCLUSIVE EXCLUSIVE

2015 Update  Folks  this is for very old versions of Android  See other answers for modern solutions     To strike through the entire text view  you can use a specific background image to simulate the strikethrough effect   android background   drawable bg strikethrough    Where the bg strikethrough drawable is a 9-patch that keeps a solid line through the middle  growing either side  with however much padding you think is reasonable  I ve used one like this          enlarged for clarity   1300            That is my HDPI version  so save it  the first one http   i stack imgur com nt6BK png   as res drawable-hdpi bg strikethrough 9 png and the configuration will work as so
