There are 2 options for this:
Using an TextView
and the Paint.STRIKE_THRU_TEXT_FLAG flag
Paint flag that applies a strike-through decoration to drawn text.
This is an example:
TextView someTextView = (TextView) findViewById(R.id.some_text_view);
someTextView.setText("$29,500");
myTextView.setPaintFlags(myTextView.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG);
Or using an Spannable Text, this is an example:
TextView myTextView = (TextView) findViewById(R.id.my_text_view);
myTextView .setText("$29,500", TextView.BufferType.SPANNABLE);
final StrikethroughSpan STRIKE_THROUGH_SPAN = new StrikethroughSpan();
Spannable spannable = (Spannable) myTextView.getText();
spannable.setSpan(STRIKE_THROUGH_SPAN, 0, myTextView.length(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
myTextView.setText(spannable);
As you can see both options are pretty similar, so you can choose one of them.
