Your problem is that youre overriding the onClickListener after first click, so the listener would only clear the paint flags after the first click.

txt.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        if(txt.getPaintFlags() == 257){
            txt.setPaintFlags(txt.getPaintFlags() | Paint.STRIKE_THRU_TEXT_FLAG); 
        } else if(txt.getPaintFlags() == 273){ 
            txt.setPaintFlags(257); 
        }
    }
});
